1-MCP结合低压静电场复合处理对红托竹荪保鲜效果的影响
Effect of 1-MCP combined with low-voltage electrostatic field composite treatment on the preservation of Dictyophora rubrovalvata
摘要
Abstract
In order to investigate the effects of different preservation methods on the storage quality of Dictyophora rubrovalvata,the fresh D.rubrovalvata,from Yibin,Sichuan province,were treated by 1-methylcyclopropene(1-MCP)slow-release stickers and low-volt-age electrostatic field(LVEF)and stored in a cold storage at 4 ℃,RH 75％.The appearance,physiological indexes,nutrients and relat-ed enzyme activities of Dictyophora rubrovalvata were examined,and correlation analysis and principal component analysis were used to in-vestigate the differences in the storage quality of this mushroom.After 12 days of storage,compared with the CK group,the 1-MCP+LVEF group could alleviate the decrease in hardness and quality loss,effectively increase the retention rate of nutrients such as reducing sugar,total phenolics and soluble protein content,significantly reduce the degree of membrane lipid peroxidation,and maintain the integ-rity of mushroom cells.Two principal components were extracted,and their cumulative contribution rate reached 95.14％in the principal component analysis,which showed that weight loss rate,hardness,reducing sugar and ascorbic acid peroxidase activity were the key inde-xes affecting the storage quality of D.rubrovalvata.In conclusion,1-MCP+LVEF preservation technology can better maintain the posthar-vest storage quality of D.rubrovalvata.This study aims to provide a theoretical basis for the development of the preservation technology of D.rubrovalvata and a new idea for its storage and marketing.关键词
