摘　　要：建立了圣女果MAP模型,在货架寿命内对不同包装方式和贮藏温度下圣女果的Vc含量、可溶性固形物含量、可滴定酸含量、失重率、感官品质5个指标进行测定。利用SPSS软件对试验数据进行了方差分析,结果表明:包装方式对圣女果失重率的显著性方差值sig=0.012<0.05,为显著影响;温度对圣女果失重率的显著性方差值sig=0<0.001,为极高显著影响;贮藏温度对圣女果可溶性固形物的显著性方差sig=0.05,为一般显著差异。试验表明,使用LDPE与CPP薄膜材料包装可以显著延长圣女果货架期;低温贮藏可以进一步提高圣女果的保鲜效果。MAP model of cherry tomato was established. Cherry tomatoes during shelf-life with different packa- ging methods and storage temperatures were tested to get 5 indicators, which were Vc content, soluble solids content, titratable acid content, weight loss rate, and sensory quality. Variance analysis of experimental data was carried out using SPSS software. The results showed that packaging methods on cherry tomato weight loss rate of significant variance of values sig=0. 012〈0.05 was significantly impact; temperature on the cherry tomato weight loss of significant variance sig= 0. 000〈0. 001 was highly significant difference; significant variance of temperature to cherry tomato soluble solids content sig = 0.05 was general for significant difference, Experiments showed that using plastic film I.DPE and CPP packaging materials can significantly extend the shelf-life of cherry tomato; low-temperature storage can further improve the fresh-keeping effect.
