莲藕采后生理生化特性研究

Studies on the Biochemistry and Physiology Proprtise of Rat-harvest Lotus Root

以新鲜莲藕为试验材料,对不同品种的莲藕在贮藏过程中的生理生化特性进行了研究。结果表明:贮藏过程中表皮白度逐渐下降,但藕肉白度变化不大;多酚氧化酶活性和多酚含量变化均呈现出先上升后下降的趋势;纤维素含量对藕的脆度变化有一定的影响;综合白度变化、脆度和腐烂率等因素来考察,3个品种中以济南大卧龙品质最优。

biochemistry and physiology of various of post-harvest lotus root were investigated. The resuits showed that during storage, the WI value of lotus epidermis were decreased, but not much change in inner lotus root; Polyphenol oxidase activity and phenols content were both showed increased and then decreased; The fiber content of lotus root can affect the change of tender; Taken the factor of WI value ,tender and decomposed rate into account, the quality of JN Dawolong was the best.
