Abstract:
The characteristics of physiological and biochemical changes of Agaricus bisporus strain W-192 harvested at three different times(according to the fungus lid and growth period,fungus lid 2-3,3-4,4-5 cm were marked as harvest times Ⅰ,Ⅱ and Ⅲ respectively) in low temperature storage(4±1)℃were studied systematically,these indexes included water content,percentage cap opening,browning degree,the respiration rate,total polyphenol,polyphenol oxidase(PPO) activity and malondialdehyde.Compared with harvest time Ⅰ and Ⅲ,the appearance of respiration peak of harvest time Ⅱ was later about 3 days,the content of malondialdehyde was always at a low level and it also had higher water content in early storage,white degree maintained good in late storage,while percentage cap opening was lower than the other two groups,harvest time Ⅱ had a better storage quality.From the analysis of fresh-keeping performance,Agaricus bisporus strain W-192 should be harvested at harvest times Ⅱ,while from biological yield the harvest times Ⅲ is appropriate for upcoming Agaricus bisporus.
