摘要
以尤溪金柑为试验材料,研究其采后贮藏过程中可滴定酸、Vc及可溶性糖含量变化,贮藏90 d后统计好果率和失重率。结果表明,4个试验点的金柑经保鲜剂处理的好果率均明显高于未处理。随着贮藏时间的延长,金柑果皮和果肉中的可滴定酸和Vc含量呈明显下降的趋势;果糖、葡萄糖含量总体呈下降的趋势,但变化幅度不大;果皮中蔗糖含量前60 d逐渐升高,随后急速下降;果肉中蔗糖含量前30 d急剧下降,随后缓慢下降。
As the materials, Youxi kumquat fruits were harvested in early December, and the fluctuations of vitamin C （Vc）, titrat- able acid and, soltible sugar were investigated every 15 days during storage. The results showed that, after 90 days of storage, the rate of good fruits treated with self-preservative was significantly higher than that of untreated huits. With the increase in storage time, titratable acid, vitamin C in the kumquat peel and pulp showed an obvious downward trend; fructose and glucose showed an o- verall downward trend, but the change was in small range; ,the sucrose of pericarp increased gradually until the 60th day, followed by a rapid decline; the sucrose of pulp declined rapidly until the 30th day, followed by a gradual decline.
