摘要
以沙田柚为试材,利用分光光度法,研究了低温和薄膜贮藏对沙田柚果实外观、失重率、还原糖、总糖、有机酸、维生素C、可溶性固形物等营养指标和商品品质的影响。结果表明:薄膜贮藏的果实还原糖、总糖、可溶性固形物和维生素C含量最低,低温贮藏和室温贮藏相比差异不显著,但低温贮藏果实有机酸含量最高,糖酸比最低。3种贮藏方式相比,不包膜室温贮藏果实失重最快,贮藏30d,失重率为11.42%;低温贮藏果实在贮藏后60d果顶部开始转绿,沙田柚采后贮藏方式以薄膜室温贮藏最佳,但贮藏时间不宜超过75d。
Taking Shatian pomelo as test materials,the effect of 4℃storage temperature and film packaging on nutritional indexes and marketable qualities of Shatian pomelo,such as sensory evaluation,weight loss rate,total suagr,reduct sugar,organic acid,the contents of soluble solid and vitamin C were studied.The results showed that the contents of total suagr,reduct sugar,vitamin C and soluble solid of fruit under film packaging room storage were the lowest.There was no significant difference between 4℃ without film and ambient temperature without film.The contents of organic acid were the highest under 4℃without film storage,while sugar-acid ratio were the lowest.Compared three different storage methods,the fruits of ambient temperature without film weightlessness was the quickest,on the 30 th day,weight loss rate was 11.42%.On the 60 th day,fruit top began to turned green under 4℃without film storage.Film packaging was the best for Shatian pomelo storaging,while time not to exceed 75 days.
