Successful cultivation of S. tuberosum L. plants require appropriate irrigation management practices and water quality assessment. This study investigates irrigation water quality parameters in two S. tuberosum L. cultivation fields (A and B), aiming to optimize water uses for sustainable production, knowing that potato is an irrigation dependent crop. A comparative analysis approach was performed, using tools such as Piper and Wilcox classification diagram with sodium adsorption ratio (SAR) index, in order to assess irrigation water quality. Key parameters were analyzed, including pH, electrical conductivity and several ion concentrations (calcium, potassium, magnesium, sodium, sulfate, bicarbonate, and chloride), which impact potato crop development and productivity. Results revealed slight variations in water quality irrigation between fields, which may affect soil preservation management strategies in the future. Irrigation water from both fields showed different hydrochemical facies: calcium bicarbonate for field A and calcium sulfate bicarbonate for field B. Data indicated the importance to monitoring salinity in field B due to the high water conductivity (1495 µS cm−1). SAR index of field B (2.53) indicates a greater potential for sodium accumulation in the soil, potentially causing soil sodification due to a high proportion of sodium concentration (138.9 mg L−1) compared to those of calcium (178.2 mg L−1) and magnesium (30.2 mg L−1). Field A showed a lower SAR index (0.71), indicating a relatively low proportion of sodium (38.7 mg L−1) compared to calcium (176.6 mg L−1) and magnesium (14.5 mg L−1). This lower potential for sodium accumulation can be beneficial for soil structure and plant growth. The integrated approach provides important data to decision-making about water and soil use based on physical and chemical parameters of the irrigation water.

Soil fertility is a critical factor for sustainable agricultural production, yet traditional soil analysis methods are often time-consuming and costly. As such, the aim of our research was to evaluate the potential of near-infrared (NIR) spectroscopy as a rapid, cost-effective, and non-destructive tool to assess soil fertility properties in agricultural soils. The soil samples were collected from the Quinta da Foz located in Benavente (Portugal) across agricultural regions including rice paddies, tomato fields, and Montado ecosystems. The sampling locations were guided by the Normalized Difference Vegetation Index (NDVI) to capture spatial variability, and soil analyses included near-infrared (NIR) spectral measurements and laboratory-based chemical determinations of soil fertility parameters (pH, electrical conductivity, total carbon and nitrogen, organic matter, macro- and micronutrients) as well as multiple soil carbon fractions. Two predictive modeling approaches (Random Forest (RF) and Partial Least Squares Regression (PLSR)) were developed to estimate soil chemical properties from spectral data. The RF models consistently outperformed PLSR, achieving high accuracy (R2 = 0.85) for nutrients such as Mg, Fe, Ni, Ca, and Na and organic matter. A moderate predictive performance (R2 between 0.70 and 0.80) was observed for different elements, namely, K and Mn. On the other hand, P, S, Zn, electrical conductivity, pH, total N, and various carbon fractions were poorly predicted. The spatial interpolation of predicted values enabled the generation of soil fertility maps that informed site-specific nutrient management. The results indicate that NIR spectroscopy combined with robust modeling offers a promising approach for rapid spatial assessment of selected soil nutrients, supporting precision agriculture and sustainable land management.

Rice (Oryza sativa L.) cultivation under flooded conditions enhances arsenic (As) mobilization and accumulation, raising concerns about food safety and human health risks. This study aimed to investigate As dynamics and mobilization in water, soil properties, fertilization practices, and in plant organs (root, culm/leaves and grain) in a paddy field located in the Tejo River Basin (Portugal), during two cropping seasons (2018 and 2019). Soil As concentrations ranging between 19 and 23 mg kg−1. The Hydrochemical analysis revealed contrasting redox environments with the stability diagrams confirming the arsenate (As(V)) dominance in floodwater and arsenite (As(III)) prevalence in soil solution. Irrigation water was classified as C3S1, evolving to C3S2 at field outlets and plant analysis demonstrated that As accumulation was predominantly confined to root tissues (> 96

The brown marmorated stink bug (Halyomorpha halys) is a major invasive pest threatening fruit production across Europe. This study integrates spatiotemporal geostatistical modelling with degree-day and photoperiod analyses to characterise its seasonal dynamics in Emilia-Romagna (Italy) from 2020 to 2022. Weekly pheromone trap data were used to quantify developmental succession among Small nymphs (early instars, N1–N3), Large nymphs (late instars, N4–N5), and Adults. Time-series and cross-correlation analyses confirmed consistent developmental delays across years, with Small preceding Large by approximately two weeks and Adults emerging after an additional two to three weeks. However, global inter-stage correlations were moderate (r ≈ 0.4–0.5), indicating substantial spatial heterogeneity among monitoring sites and suggesting that regional averages do not fully capture local population dynamics. To address this variability, a three-dimensional spatiotemporal geostatistical model (space × time) was implemented using Direct Sequential Simulation. The model successfully reproduced seasonal population waves and interannual differences in onset and persistence. The identification of persistent hotspots and stage-specific temporal windows is biologically relevant because it highlights where and when H. halys populations are most likely to increase. As such, from an IPM perspective, these outputs can support earlier monitoring, more precise timing of management interventions, and spatial prioritization of control efforts. These findings demonstrate that combining stage-specific temporal analysis with spatially explicit modelling improves forecasting accuracy and supports more precise timing of biological and chemical interventions. The proposed framework provides a scalable tool for climate-responsive integrated pest management in fruit-growing systems.

Arsenic (As) accumulation in rice (Oryza sativa L.) is considered a major environmental and food safety concern, particularly in flooded agroecosystems where reducing conditions mobilize As from soils. Portugal is one of Europe’s rice producers, especially in the Tejo, Almansor, and Sorraia valleys. As such, this study evaluates As pathways across 5000 ha of rice fields in the Tagus, Sorraia, and Almansor alluvial plains by combining soil, water, and plant analyses with a geostatistical approach. The soils exhibited consistently elevated As concentrations (mean of 18.9 mg/kg), exceeding national reference values for agricultural soils (11 mg/kg) and forming a marked east–west gradient with the highest levels in the Tagus alluvium. Geochemical analysis showed that As is strongly correlated with Fe (r = 0.686), indicating an influence of Fe-oxyhydroxides under oxidizing conditions. The irrigation waters showed low As (mean of 2.84 μg/L for surface water and 3.51 μg/L for groundwater) and predominantly low sodicity facies, suggesting that irrigation water is not the main contamination vector. In rice plants, As accumulation follows the characteristic organ hierarchy roots > stems/leaves > grains, with root concentrations reaching up to 518 mg/kg and accumulating progressively in the maturity phase. Arsenic content in harvested rice grains was 266 μg/kg (with a maximum of 413.9 μg/kg), being close to EU maximum limits when considering typical inorganic As proportions, assuming 60 to 90% inorganic fraction. Together, the findings highlight that a combined approach is essential, and identify soil geochemistry (and not irrigation water) as the primary source of As transfer in those agroecosystems, due to the flooded conditions that trigger the reductive dissolution of Fe oxides, releasing As. Additionally, the results also identified the need for targeted monitoring in areas of elevated As content in soils and support future mitigation through As speciation analysis, cultivar selection, improved fertilization strategies, and water-management practices such as Alternate Wetting and Drying (AWD), to ensure the long-term food safety.

The winemaking industry represents one of the most important sectors of the Mediterranean agrifood economy, generating large amounts of solid residues, especially grape pomace. The study aimed to evaluate during two consecutive harvest years the influence of the production system (conventional vs. organic) and cultivar on the mineral, chemical, and antioxidant composition, as well as the colorimetric properties, of grape pomaces obtained from four Vitis vinifera L. cultivars in Alentejo-Portugal. The results showed that mineral composition was significantly affected by both production system and cultivar, with organic grape pomace showing higher K and Mn contents, whereas Ca and Cu showed consistently higher content under conventional. Protein content tended to increase under organic production, while fiber and fat were overall higher in conventional, particularly in the first year. Sugars displayed strong cultivar specificity, with Arinto showing the highest concentrations (30 to 40%), and considering all cultivars, total phenolic content ranged between 4000 ando 9000 mg GAE/100 g, while antioxidant capacity varied among cultivars and years. Colorimetric parameters were essentially influenced by cultivar and harvest year rather than production system. The PCA revealed that PC1 (44.06%) represented a gradient associated with mineral and antioxidant composition, while PC2 (21.26%) reflected minor variation in color and sugars, and the hierarchical clustering distinguished Syrah and Alicante Bouschet as the cultivars most responsive to production system, whereas Aragonez and Arinto exhibited greater compositional stability across years. Overall, the findings indicate that both cultivar and management practices (organic and conventional) influence the compositional profile of grape pomace, with organic showing a tendency to enhance K, Mn, protein, and antioxidant parameters, whereas conventional practices favored higher levels of Ca, Cu, and fiber. The results provide valuable insights for the valorization of grape pomace and the development of sustainable viticultural strategies in Mediterranean environments.

Grape pomace (i.e., the residual skins, seeds, and pulp left after vinification) retains up to 70% of the fruit’s original phenolic compounds and is also rich in dietary fiber. As such, because this by-product is generated in large quantities worldwide and its disposal is both technologically problematic and costly, reusing it as a food ingredient could simultaneously mitigate environmental burdens, lower winery waste-management expenses, and enhance the nutritional profile of fortified foods. In this context, this study investigated the nutritional enrichment of dark chocolate by incorporating flour produced from red (cv. Syrah) and white (cv. Arinto) grape pomace at three levels (5, 10, and 15% w/w). Formulated chocolates and controls were manufactured under industrial tempering conditions and subsequently analyzed for protein, lipids, sugars, dietary fiber, total phenolic content, antioxidant capacity (DPPH and ORAC), color, texture, and consumer perception (hedonic test). All fortified samples showed higher fiber and antioxidant activity than the control, with “White_15” showing higher fiber content (43.1%) and “Red_5” for ORAC (69,483 µmol TE/100 g) and DPPH (6587 µmol TE/100 g). Dietary fiber showed an increase in content with the increase in grape pomace incorporation, regardless of the type (red or white). Texture softening was observed in all fortified chocolates independently of the incorporation level or type (red or white). Principal Component Analysis (PCA) and hierarchical clustering confirmed clear separation between control and fortified chocolates based on the parameters analyzed. Sensory evaluation with untrained panelists revealed good overall acceptability across all formulations. These findings demonstrate that grape pomace flour can be effectively valorized as a functional ingredient in dark chocolates, supporting circular economy practices in the wine and confectionery sectors while delivering products with enhanced health-promoting attributes (nutritional and antioxidant).

Potato (Solanum tuberosum L.) is an important global food crop, being greatly valued for its high carbohydrate content and nutritional profile. In response to the world population’s rapid growth and the increasing need for nutritionally enhanced food quality, potato biofortification has become a key focus of agronomic research. This study investigated the effect of calcium (Ca) biofortification on two potato cultivars (Picasso and Rossi) cultivated in Portugal, assessing its impact on the photosynthetic functioning and the Ca content and distribution of tubers. At the beginning of the tuberization stage, seven foliar applications of CaCl2 or Ca-EDTA at 12 kg ha−1 were performed. The application of Ca-EDTA led to an increased Ca content in peeled tubers of Picasso (37%) and Rossi (16%), and 88% and 79% in unpeeled tubers, in the same cv. order and as compared to their controls, with Ca predominantly accumulating in the epidermis/peel region. Photosynthetic performance was negatively impacted by the Ca-EDTA treatment in Picasso but not in Rossi, which was reflected in the significant declines in net photosynthesis (Pn) and maximal (Fv/Fm) and actual (Fv′/Fm) photochemical efficiency of photosystem II. Additionally, both genotypes showed negative impacts (greater in Picasso) on the quantum yield of non-cyclic electron transport (Y(II)) and photochemical quenching (qL) after five foliar applications. This contrasted with the absence of negative impacts under the use of CaCl2, which resulted in 17.1% (Picasso) and 29.5% (RFossi) increase in Ca content in peeled tubers, without any significant differences between the unpeeled tubers of both cvs. Moreover, only with CaCl2, the tuber weight and yield were not negatively impacted. These findings pointed out that, although with a lower Ca increase in the tubers, CaCl2 was the best suitable option for the Ca biofortification of these cvs. at the applied doses.

Potato (Solanum tuberosum L.) is the world’s fourth most important food crop and is considered a staple food. Nutrient absorption in potato plants is influenced by different factors such as soil properties (namely mineral element composition). This study aimed to assess Ca, K, S, and Fe dynamics in three potato cultivars (Agria, Désirée, and Red Lady) grown across different soil types. As such, soil analyses were carried out before and after cultivation, revealing different variations in Ca, K, S, and Fe content. The results demonstrated that mineral distribution in the different plant organs (leaves, stems, roots, and tubers) showed distinct patterns, with Ca accumulating preferentially in leaves, K in stems, S in roots, and Fe in leaves. Mobilization efficiency was also evaluated and followed a specific pattern across all cultivars and soil types: K > S > Fe > Ca, reflecting the mineral translocation efficiency of these mineral elements within plant tissues to tuber. No significant differences were observed in tuber weight, or minimum and maximum diameter, indicating that these quality parameters were not influenced by the soil type. Fresh weight of tuber biomass assessment showed variability among the different cultivars and soil types. Principal component analysis showed that Ca content is associated with productivity parameters as well as K, contributing to tuber yield. Overall, cultivar-based variations in mineral uptake patterns were identified, suggesting that both genetic and environmental factors play an important role in mineral element absorption and translocation efficiency. This study highlights the importance of understanding mineral element dynamics in S. tuberosum L. cultivation, in order to optimize tuber yield and quality.

Seven commercially available apples varieties in Portugal (Jongold, Pink Lady, Reineta, Fuji, Gala, Golden and Granny) were analyzed for their physical and chemical properties. In this context, mineral content, height, weight, diameter, firmness, total solids soluble content, color, total lipids content and total protein content were carried out. Mineral content was assessed using X-ray fluorescence spectrophotometry in apples with and without peel, revealing significant differences between each variety. Moreover, there were significant differences between height, dry weight content, density, total soluble solids content, firmness, size, colorimetric parameter. Furthermore, significant differences were also observed in Fe, Ca, K, Cl and S content as well as protein and total lipid content. Additionally, Reineta variety emerged as the sweetest variety among the studied varieties and the study also revealed that the mineral content was higher in apples with peel compared to those without peel, highlighting the nutritional importance of apple skin.

Potato (Solanum tuberosum L.) is the world’s third most popular vegetable in terms of consumption and the fourth most produced. Potatoes can be easily cultivated in different climates and locations around the globe and often in soils contaminated by heavy metals due to industrial activities. This study assessed heavy metal accumulation in different organs of three S. tuberosum L. varieties (Agria, Désirée, and Red Lady) grown in different substrate formulations containing slag and waste from the Caveira polymetallic sulfite mine in Portugal. Results reveal that Cu, Pb, and As accumulation in the different organs of the plant depends on variety and substrate formulation, with tubers exceeding reference values from the literature. Tubers accumulated less Cu (varying between 17.3 and 32 mg/kg), Pb (varying between 5 and 27.6 mg/kg) and As (varying between 4 and 14.8 mg/kg) compared to other plant organs, and the Désirée variety exhibited high Pb (with a maximum of 27.6 mg/kg) accumulation in tubers compared to the remaining varieties. Although the phenological development of plants was not impacted, substrate formulation played a critical role in the plant’s metal uptake. The Agria variety presented a lower contamination risk in tubers, but potato cultivation in contaminated soils can present a risk to human health.

Dialium guineense (velvet tamarind), Parkia biglobosa Jacq. (African locust bean) and Adanosonia digitata L. (baobab) are fruits from African plants whose nutritional potential remains poorly characterised. As such, their pulps and seeds were analysed for colour (CIELab system), moisture, ash, protein, fat, soluble and insoluble dietary fibre, free sugars (HPLC-RI), organic acids (HPLC-PDA), macro and microelements (XRF analyser) and amygdalin (HPLC-PDA). The colours of their pulps differed considerable (ΔE > 38 between the velvet tamarind and African locust bean) and the moisture content was lower in seeds (about 7%) compared to pulps (9–13%). Seeds were more concentrated in protein (20–28%) and fat (5–22%), whereas pulps were richer in sugar (1–12%). African locust bean pulp was the sweetest (39% total sugar), while baobab pulp contained the highest soluble fibre (>30%) and citric acid (3.2%), and velvet tamarind pulp was distinguished by its tartaric acid content (3.4%). Seeds of the African fruits presented higher Ca, P, S and Fe contents, whereas pulps had higher K content. No amygdalin (<6.34 mg per 100 g of dry weight) or toxic heavy metal contents were detected. The PCA segregated samples by pulp and seed and the PC1 explains the sugar and moisture of the pulps, while protein, fat and minerals are associated with the seeds. These data confirm that African fruit pulps and seeds have distinct functional profiles, are safe for food use and can be consumed, which is important for efforts to promote the conservation of these tropical plant species.

Zinc enrichment of edible food products, through the soil and/or foliar application of fertilizers, is a strategy that can increase the contents of some nutrients, namely Zn. In this context, a workflow for agronomic enrichment with zinc was carried out on irrigated Vitis vinifera cv. Syrah, aiming to evaluate the mobilization of photoassimilates to the winegrapes and the consequences of this for winemaking. During three productive cycles, foliar applications were performed with ZnSO4 or ZnO, at concentrations ranging between 150 and 1350 g.ha−1. The normal vegetation index as well as some photosynthetic parameters indicated that the threshold of Zn toxicity was not reached; it is even worth noting that with ZnSO4, a significant increase in several cases was observed in net photosynthesis (Pn). At harvest, Zn biofortification reached a 1.2 to 2.3-fold increase with ZnSO4 and ZnO, respectively (being significant relative to the control, in two consecutive years, with ZnO at a concentration of 1350 g.ha−1). Total soluble sugars revealed higher values with grapes submitted to ZnSO4 and ZnO foliar applications, which can be advantageous for winemaking. It was concluded that foliar spraying was efficient with ZnO and ZnSO4, showing potential benefits for wine quality without evidencing negative impacts.

Zinc deficiency affects the population worldwide, being developed several strategies to mitigate this health problem, such as agronomic biofortification. The absence of an adequate amount of Zn affects growth, immunity, and reproductive system. Accordingly, a technological itinerary for Zn agronomic biofortification was outlined using grapes Vitis vinifera cv. Moscatel (i.e., with irrigation), aiming the optimization of the Zn content, and the determination of potential implications in some quality parameters. Along the production cycle, three foliar applications of ZnSO4 and ZnO fertilizers were performed at the concentrations of 0, 450 and 900 g ha─1 (with the control being sprayed with water). At harvest, all biofortified grapes showed an increase in Zn content (greater at maximum concentrations of 900 g ha─1), with ZnO-grapes achieving a 4.2-fold increase. Through the tissue analyses (µ-EDXRF) a Zn accumulation in the seeds was found after the application of Zn fertilizers. Moreover, sugar analyses presented mainly glucose and fructose within the range of 7.70–13.22

There is a growing need for strategic actions involving efficient water use, sustainable agricultural production, and food security. Agricultural productivity can be improved through good agricultural practices based on water-quality management, new genetically modified resources, and using precision agriculture. This study aimed to monitor the crop water (supply, irrigation, and flooding) of an advanced rice (Oryza sativa L.) line of the breeding program (OP 1509) subjected to Selenium (Se) enrichment. Water lines in a paddy rice field were monitored by Unmanned Aerial Vehicles (UAVs). The parameters of pH, pHs, electrical conductivity, temperature, HCO3−, Cl−, SO42−, PO43−, Na+, K+, Ca2+, and Mg2+ were analyzed. According to the Piper diagram, the samples were classified as sodium chloride bicarbonate (supply) and sodium bicarbonate chloride (irrigation and flooding). The Langelier Saturation Index (LSI) was calculated and indicated that waters are good to use in agricultural practices. According to the Wilcox classification, regarding agriculture use, the samples were classified as C2S1 (supply and irrigation) and C3S1 (flooding). The Selenium contents were analyzed by atomic absorption and significant differences were observed in rice grains, with a maximum content of 10 mg.kg−1. In conclusion, the water quality is in accordance with the parameters for use in this crop and the workflow used improved the grain quality.

Tackling human malnutrition resulting from mineral deficits in foods is currently an agro-industrial problem. To address this problem, an agronomic workflow to enrich Rocha pears with calcium (Ca) was considered in two orchards in Portugal. This study aims to assess quality differences in the irrigation water of two orchards (of Rocha pear) where an agronomic Ca enrichment workflow would be performed and identify possible conditioning to Ca increases in fruits. Thus, electrical conductivity (EC), pH, pHs, cations (Na+, K+, Ca2+, and Mg2+), and anions (HCO3−, Cl−, and SO42−) were attained to calculate the Sodium Adsorption Ratio (SAR) index and the Langelier Saturation Index (LSI) and assess the agricultural use. The values of EC, pH, pHs, SAR index and LSI of both orchards varied between 1198 and 1211 µS/cm, 7.4 and 7.5, 7.7 and 8.1, 3.5 and 7.4, and −0.69 and −0.21, respectively. Regarding Piper classification, irrigation waters were classified as sodium bicarbonate (orchard 1) and sodium chloride bicarbonate (orchard 2). Both orchards presented different classifications regarding agricultural use, namely C3S1 (orchard 2) and C3S2 (orchard 1). The water of both orchards presented the same salinity hazard (C3), but the use of these irrigation waters is enabled since these trees can be considered salt-tolerant. However, regarding the alkalinization hazard to soils, the irrigation water from orchard 2 offers less danger (S1) in comparison to orchard 1 (S2). Meanwhile, a slightly inferior LSI (orchard 1) can favor a higher tendency to dissolve calcium carbonate. In conclusion, although slightly different, analysis indicated that the waters of both orchards did not induce toxicity in Rocha pear trees.

Iron (Fe) and zinc (Zn) are micronutrients commonly linked to nutritional deficits. Inadequate intakes of Fe can be linked to impaired cognition, weakness and fatigue or pathologies such as anemia. As for Zn, cell damages, stunting or increases in infection susceptibility can occur. In Portugal, an enrichment workflow with foliar sprays was performed, to increase Fe and Zn contents in two organically produced tomato cultivars. A total of 4 foliar sprays with a mixture of Maxiblend (concentrations of 1–7 kg/ha) and Zitrilon 15

Potato (Solanum tuberosum L) is one of the most important food crops worldwide, being a carbohydrate-rich food and presenting a good source of vitamins and minerals. Moreover, the mineral enrichment of potatoes through foliar appli-cation has been implemented over the years, namely in calcium (Ca). As such, this study aimed to assess the Ca effect on some quality parameters in three varieties of tubers of Solanum tuberosum L. plants produced in Portugal (Agria, Picasso, and Rossi) and submitted to Ca biofortification process carried out with two types of Ca (CaCl2 and Ca-EDTA) and two different concentrations (12 and 24 kg.ha-1), at harvest and after four and eight months under cold storage con-servation. The Ca content increased with the biofortification treatments in the three varieties relative to control tubers and different correlations were observed between the mineral elements analyzed (Ca, P, K, Fe, Zn, and Mg). Only Agria (the control and treatment with 24 kg.ha-1 of Ca-EDTA) was found suitable for industrial processing in the three periods analyzed (harvest, 4M and 8M) and overall, both in raw and cooked tubers, there were differences between each variety considering the work strength, adhesiveness and CIELAB parameters (L, a*, and b*).

Remote sensing technology (namely UAVs) has been used to monitor potato crops. As such, this study aims to analyze the relationship between the NDVI model and yield productivity in Solanum tuberosum L. plants from the Agria variety, submitted to a Ca biofortification process with two different concentrations (12 and 24 kg/ha) of CaCl2 or Ca-EDTA. The NDVI values were collected six days after the six foliar applications and analyzed alongside the Ca content in the potato tubers (at harvest) and the total yield. The results highlight the fact that 24 kg/ha of CaCl2 presented the lowest NDVI value, yet these plants did not show the lowest yield. Moreover, that same treatment presented the highest Ca biofortification index in tubers. Also, it seems that the NDVI can be used in decision making to improve crop management strategies, considering that it is an indicator for detecting plant growth or vigor; however, in this research, it is not sufficient for yield prediction.

Human malnourishment is a current problem of society, and agronomic biofortification is a procedure that wishes to tackle these mineral deficits in human diets by increasing a specific nutrient in the edible part of food crops. Calcium is an important mineral element that performs structural functions and thus can help prevent the development of pathologies such as osteoporosis. Thereby, this work aims to study the impact of calcium enrichment on fatty acid (FA) content in Rocha pears. Thus, an agronomic enrichment workflow with seven foliar sprays of CaCl2 (with concentrations between 4–8 kg/ha) was performed in an orchard located in the western region of Portugal. Besides Ca enrichment assessment in fruits (with a portable X-ray fluorescence analyzer) at harvest, fatty acids quantification and FA profile (acquired with a gas–liquid chromatograph, coupled to a flame ionization detector (GC-FID)), double bond index (DBI), and lipoperoxidation values (with a spectrophotometer) were also attained. Increases of Ca in sprayed fruits reached 7.6% to 44.3%. For FA-related parameters, no significant differences were observed, suggesting that Ca sprays did not impact these parameters. Total fatty acids (TFA), DBI, and lipoperoxidation values varied between 0.72–0.74 g/100 g FW, 8.13–9.83 and 2.23–3.18 µM/g FW, respectively. The following FA profile was attained: C18:2 > C16:0 > C18:3 > C18:0 > C18:1 > <C16:0. No significant differences were observed. In summary, CaCl2 can be used to increase Ca levels in fruits, allowing the production of fruits with prophylactic characteristics, while the concentrations from this study did not impact their FA content. Overall, this suggests that cell compartmentation and membranes’ regular functioning were maintained, suggesting the absence of lipid decay and avoiding a potential increase in storage losses.
