摘要
探讨了复配叶绿素铜钠保鲜涂膜在常温下对草莓的货架期的影响,通过草莓腐烂度、总酸度、VC和可溶性糖的含量变化来评定保鲜效果。结果表明:用叶绿素铜钠、NOCC和丙二醇-1,2复配制成的保鲜涂膜具有较好的水溶性和成膜性,在贮藏期间能有效降低草莓的呼吸强度,减少水分及营养物质的损失,推迟草莓的衰老,使草莓的货架期达到5d,比未处理的草莓货架期延长4d。
The effect on shelf life of strawberry by compound membrane of Chlorophyllin Copper Sodium at ambient temperaturehas been Studied. The effectiveness of fresh keeping was evaluated by testing the rotten degree, acidity, VC and sugar solubility of strawberries. The result showed that fresh keeping membrane which prepared by Chlorophyllin Copper Sodium. NOCC and 1,2-propylene glycol was more water-soluble. It could lower the respiration strength of the fruit and vegetable effectively and delayed the consenescence of strawberry during shelf life period. It could prolong the shelf life of strawberry to 5d, which has extended 4d compared to those untreated.
