摘要
以马来6号番木瓜果实为试材,用不同浓度壳聚糖(CTS)涂膜处理后放入人工气候箱中于(理25可±显2)℃著下降贮低藏膜,脂研过究氧了化壳过聚程糖中对脂常氧温合保酶鲜(番LO木X瓜)活膜性脂的过增氧长化的,减影缓响超。氧结阴果离表子明(,O一2-)定的浓产度生的速壳率聚,提糖高处超氧化物歧化酶(SOD)和超氧化物酶(POD)等膜保护酶的活性,减少了膜脂过氧化物产物丙二醛(MDA)的积累,从而有利于果实硬度的维持。结论:壳聚糖可减轻膜脂过氧化程度,延缓番木瓜果实的后熟,以1.25%处理浓度最好。
In this report, the effect of Chitosan （CTS） on the membrane lipids peroxidation of papaya fruits （CV. Malaya 6 # ） was studied, which were stored in artificial bioclimatic chamber under room temperature （25 ±2）℃ after dip coating with different contents of CTS. The results indicated that proper content of CTS could reduce the activity growth of Lipoxygenase （LOX）, slow down the production rate of superoxide anion （O2-）, enhance the activity of Superoxide Dismutase （SOD） and Peroxydase （POD）, decrease the content of Malonaldehyde （MDA）, then keep higher firmness of papaya fruits during the storage. So it can be drawn a conclusion that CTS has effect on alleviating the peroxidation degree of membrane lipids, prolonging the store maturity time of papaya fruit. The best content of CTS is 1.25%.
