Ant lipids have been an integral part of traditional medicine in Asia for ages, yet, their nutritional and functional properties remain underexplored. The current study examines the use of three green solvents (ethanol, ethyl acetate, and their binary mixture) for the study of novel extraction kinetics and characterization of lipids from red weaver ants (Oecophylla smaragdina). The solvent, solid-to-solvent ratios (1:10, 1:20, 1:30) and time intervals (5-180 min) were varied for the extractions so as to assess the impact of process parameters on the yield of the lipid fraction. Kinetic modeling with Peleg, Page, and Lewis first-order models proved Peleg's model to be the most accurate in describing the extraction kinetics, as it provided the best fit to the experimental data. Ethanol consistently exhibited highest extraction efficiency, giving the highest lipid recovery at a 1:20 solid-to-solvent ratio, which was due to the increased solvation effects. The ant oil obtained was very rich in bioactive fatty acids such as oleic acid (C18:1), palmitoleic acid (C16:1), palmitic acid (C16:0), lauric acid (C12:0), which are known for their heart protective, antimicrobial and anti-inflammatory actions. The lipid also included long-chain hydrocarbons like eicosane, triacontane, and hexatriacontane and fatty alcohols like n-tetracosanol-1, which not only imparts the lipid matrix structural stability but also oxidative resistance, thus signifying its potential therapeutic and nutritional value. The use of different solvents in extraction greatly influenced the separation and characteristics of the lipids as revealed by comprehensive molecular and structural analyses. To evaluate the environmental sustainability of the suggested technique, the Analytical Green Star Area (AGSA) and Analytical GREENNESS (AGREE) metrics were utilized. Both tools indicated that the used solvents were ecologically sustainable, recommending its use as an eco-friendly alternative for the regular analysis of the examined medications. The findings of this study provide a strong foundation for the development of red weaver ant lipids as a sustainable and functional superfood ingredient with substantial nutritional and industrial applications.
The growing global demand for proteins has prompted greater investigation into alternative, sustainable, and nutritionally comparable protein sources. Insects are emerging as sustainable and eco-friendly protein sources, yet extraction techniques critically influence the physicochemical and functional properties of insect-derived proteins. This study examines the effects of ultrasonic amplitude (10%-50%) and time (5-30 min) on the extraction yield, functional, structural, and surface properties of red weaver ant egg protein isolate. Extraction kinetics were evaluated using first-order, second-order, Peleg, and power law models; Peleg and second-order models showed the best fit (R 2 = 0.99), indicating superior suitability for protein extraction. Maximum yield and purity were achieved at 50% amplitude and 20 min. The optimized ant egg protein isolate exhibited enhanced water (4.58 +/- 0.9) and oil holding capacities (2.28 +/- 0.1), reduced particle size (250.3 +/- 1.9), negative zeta potential, and higher sulfhydryl group, which has a positive effect on protein solubility, emulsifying activity, and stability index (60.34 +/- 0.2 and 68.8 +/- 0.97, respectively). FTIR and XRD structural evaluation revealed a slight decrease in beta-sheets with a corresponding increase in alpha-helix, suggesting secondary structural rearrangements that enhance functionality and thermal stability. DSC analysis further confirmed enhanced enthalpy values compared to the control. SEM observations showed reduced particle size and a more disrupted, fragmented morphology, attributable to cavitation-induced shear forces. These results highlight ultrasound-assisted extraction as a sustainable approach for producing nutritionally valuable ant egg protein suitable for diverse food applications. Overall, this study provides a scientifically validated pathway for industry adoption of insect-based protein using ultrasound technology, bridging the gap between laboratory research and real-world food applications while supporting global goals of food security and environmental sustainability.

Millets are small-grained, climate-resilient cereals that assume great significance in imparting sustainable food and nutritional security. Besides their agronomic advantages, the millets are highly nutritious and contain a wide range of phytochemicals with human health beneficial properties. There has been a recent surge in the consumption of these heritage grains and food technologists across the globe are exploring several heat-imparted processing methods for developing improved products out of these gluten-free grains. Therefore, this work aims to serve as a resource covering the state-of-the-art known information about the conventional and emerging thermal processing techniques employed in millets. However, identifying a specific conventional or emerging technique for precise improvement in nutritional or overall quality remains a distant goal, as the effects of these techniques depend on factors like dosage, duration, and other process-related variables, along with the dynamics of the food matrix. This review not only analysed the common thermal processing methods used for millets but also their influence on nutritional quality, digestibility, bio accessibility, and bioavailability. Understanding these changes can aid in developing new millet-based food products that meet consumer demands, enhance market potential, and support health claims. Overall, this area of research is still under-explored, and future research on emerging technologies and value-added millet products should take into account the relationship between composition and nutrient bioavailability.

Kadamb fruit (Neolamarckia cadamba) is considered as an underutilized fruit in the world despite its nutritional and therapeutic values. This research work emphasized on the determination of some engineering, structural, and thermal properties of Kadam fruit. Moreover, mass was predicted based on measured physical properties using linear, quadratic, and power models. This fruit has an arithmetic mean diameter of 49 mm and sphericity of 0.97 which is inferred as spherical in shape. The angle of repose was found to be 59.53 degrees and the coefficient of friction on the galvanized steel surface was 0.18. Due to its higher moisture content (75%-80% wb), Kadamb fruit is perishable in nature. Linear, quadratic, and power models were used to fit the experimental data to predict mass of the fruit. Goodness of fit was judged based on higher correlation coefficient values (R-2 > 0.85). The flakiness ratio best predicted the mass of the Kadamb fruit. The average values of hardness and hardness deformation for Kadamb fruit were observed to be 51.71 +/- 3.26 N and 10.70% +/- 1.21%, respectively. The glass transition temperature (T-g) of the fruit was recorded as 58 degrees C by a differential scanning calorimeter. Infrared spectrum analysis showed the presence of aliphatic amines, ketones, carboxylic acid, alcohol, ester, ether, and phenols. The crystallinity index of ripe fruit, raw fruit, and peel was found to be 0.35, 0.30, and 0.30, respectively. This experimental result on engineering, thermal, and structural properties, along with mass modeling on Kadamb fruit will be helpful in the design and development of post-harvest machinery and value addition thereafter. Practical Applications The exponential growth of the world population has stood as the most significant challenge in front of food scientists to look for alternative food sources. Kadamb fruit could fill the food bowl of human beings because of its nutritional components, polyphenols, and other phytochemicals. Studies on engineering properties and mass modeling of Kadamb fruit could be the first step in adopting food processes for value addition. This study would be helpful in developing and designing post-harvest handling equipment like graders, sorters, cleaners, and the development of novel products and utilization of its by-products.
Feedstock availability and unremitting supply are decisive factors for the development of bioenergy systems and the bio-based economy of the near future. A holistic approach to biowaste valorization could be a valuable addition to the feedstock supply. The tea industry is one of the most important agro-based contributors to the Indian economy and produces a significant amount of around 190,400 tons of homogeneous biowaste every year, which is currently generally used as fertilizers. These homogeneous waste streams are essential for waste-based biorefineries. In this regard using tea industry waste as a feedstock for the production of energy and value-added chemicals could be a promising and viable opportunity for increasing the circular bioeconomy. This chapter is an endeavor to critically illustrate an up-to-date review of the various waste valorization techniques and the integration toward a biorefinery concept using tea waste for the production of energy and value-added products. This is considered significant in view of the fact that the waste generated during tea processing could be a viable option for waste utilization, resource mobilization, and wealth generation. This could also help in improving the overall economics of tea cultivation and its processing in a typical tea management system.
