弱酸性电位水结合壳聚糖对银耳活性氧代谢的影响
Influence of Slightly Acidic Electrolyzed Water and Chitosan Treatment on Activate Oxygen Metabolism of Tremellafuciformis
摘要
Abstract
In order to solve the issues of intolerant preservation of Tremellafuciformis,the effects of different treatments on changes of physiological characteristics related to active oxygen metabolism of post-harvest T.fuciformiswere investigated by using four different processing methods on direct storage,chitosan coating,slightly acidicelectrolyzed water(SAEW) immersion cleaning and SAEW-assisted chitosan processing.The results showed that the processing of SAEW cleaning and chitosan coating can play a favorable preservation but the corrosion resistance appeared to weaken at later storage period.SAEW-assisted chitosan processing was superior to other treatments in some indexes.In the 10 d storage period,the total number of colonies,microbial respiration rate and biochemical index maintained at low levels but no greater volatility,the activity of antioxidant enzymes(SOD,POD and CAT) remained at a high level,the decreased rate of non-enzyme antioxidants (AsA and GSH) was significantly lower than that of the other experimental group (P ＜ 0.05).The conclusion provided a new useful method for safer preservation of T.fuciformis.关键词
