The fruit body of Lepista sordida cultivated with main substrate of tea tree sawdust was used as the experimental samples. The FAO/WHO pattern and amino acid ratios coefficient method were used to evaluate sample from the aspects of mineral and amino acid nutrition. The results showed that the sample is rich in Fe, Zn, Se and various amino acids, of which the Fe content was as high as 388 mg·kg-1. Except for As, which was slightly higher than the limit of As contaminants in edible fungi, the contents of Cd and Pb were all within the limits of standards. Umami amino acid>sweet amino acid>aromatic amino acid among the six flavor amino acid contents. Among them, the umami amino acid(Asp+Glu) accounts for 58.37%. By further analysis showed that the value of EAA/TAA was 0.31, and the EAA/NEAA was 0.46, which were all lower than the high-quality protein standard proposed by FAO/WHO. Thr and Lys were relative excess, Ile was the first limiting amino acid of thesample, the score of ratio coefficient of amino acid in the sample was 78. Although there was a gap between the sample and the model spectrum standard of the amino acids, they met the nutritional needs basically.
[Objective]The effects of different agents combinations of chlorphopham(CIPC),carvone and chlorine dioxide(ClO2)on the storage of sweet potato were explored to provide the scientific basis for its application in the production.[Method]Taking chlorine dioxide(ClO2)as the preservative,and carvone and CIPC as the bud inhibitor in the experiment,the effects of different combinations[non-preservative+non-bud inhibitor(A1B1),non-preservative+carvone(A1 B2),non-preservative+CIPC(A1B3),ClO2+non-bud inhibitor(A2B1),ClO2+carvone(A2B2)and ClO2+CIPC(A2B3)]on the storage of sweet potato were studied by two-factor experiment with randomized block design.[Result]With the prolonging of the storage,the germination rate of Ziyun red core sweet potato under six treatments showed an increasing trend.The germination rate of all treatments(except A2 B2)on 90 d was 1.23%-25.43%,among which A1B3 was the highest,A2B3was the lowest.The germination rate of all treatments on 105 d and 120 d was 2.97%-37.17%and 10.57%-62.03%,among which A1B3 was the highest,A2 B2 and A2B3were the lowest.The germination rate of all treatments on 135 d was 18.17%-100.00%,among which A1B1was the highest,A2 B2 was the lowest.Applying preservative could effectively inhibit weight loss rate and decay rate of sweet potato,while the effects of applying bud inhibitor were not obvious.When the Ziyun red core sweet potato were stored on 135 d,the average weight loss rate of different treatments was 27.72%-41.56%,following A1B1>A1B3>A1B2>A2B2>A2B1>A2B3;The average decay rate was 11.00%-39.67%,following A1B1>A1B2>A1B3>A2B1=A2B3>A2B2.[Conclusion]During the storage period,the combined application of ClO2 and carvone could effectively inhibit the germination of tubers,reduce the weight loss rate of tubers and delay the deterioration of quality.ClO2 had good preservative effect and could be used in actual production.
