摘要: Metabolic changes of mushroom (Flammulina velutipes) applied with polyethylene (PE) material (Normal-PM) or nanocomposite reinforced PE packaging (Nano-PM) were monitored using tandem mass tags (TMT) labeling combined two-dimensional liquid chromatography-tandem spectrometry (2D LC-MS/MS) technique. A total 429 proteins investigated as differentially expressed (DEPs) among treatments after a cold storage period. 232 DEPs up-regulated and 65 down-regulated in Nano-PM packed F. velutipes compared to that Normal-PM. The mainly involved amino acid synthesis metabolism, signal transduction, response stress while the largely located mitochondrion participated carbohydrate metabolic, organic metabolic. It was also revealed could inhibit energy metabolism bioprocess, promote acids biosynthesis,...
