代谢组揭示低温储藏蛹虫草干制品中风味的变化及最佳食用时间
Metabonomics reveals the changes of flavor and the best eating time of dried Cordyceps militaris products stored at low temperature
摘要
Abstract
Postharvest Cordyceps militaris has high moisture content,and fresh products are prone to mechanical damage and microbial infection.Therefore,the products in the market are mainly dry products and secondary processed products,and mainly stored at room temperature without vacuum sealing.In this study,liquid chromatography-mass spectrometry(LC-MS)and gas chromatography-mass spectrometry(GC-MS)were used to analyze the changes of main metabolites of dried C.militaris products stored at 4℃for 1-6 months.In total,856 non-volatile substances and 431 volatile substances were identified by metabonomics,among which 159 non-volatile substances and 110 volatile substances were screened by difference significance analyses.Further analysis showed that the non-volatile metabolites fluctuated significantly during three months of prestorage,and the components tended to be stable after three months of storage.The volatile components reached equilibrium after two months of storage.This study provides a new insight for exploring the eating time of dried C.militaris products.关键词
