采用蜂胶涂膜剂对圆脆鲜枣进行保鲜处理,通过测定贮藏期鲜枣的腐烂指数、失重率、硬度、可溶性固形物含量、可滴定酸含量、Vc含量及呼吸强度的变化,评价其对圆脆鲜枣的保鲜效果。结果表明,蜂胶涂膜保鲜处理可以显著地降低圆脆鲜枣的失重率和腐烂指数,维持圆脆鲜枣的硬度,抑制可溶性固形物含量、可滴定酸含量和Vc含量的下降及呼吸强度增大,能明显延缓圆脆鲜枣采后的衰老,有效延长圆脆鲜枣的贮藏保鲜期,1.5%蜂胶涂膜处理保鲜效果最佳。
The fresh-cut crisp jujube was treated with propolis-coating agent. The decay index, weight loss rate, hardness, soluble solids content, titratable acidity, Vc content and respiration intensity of fresh jujube were evaluated during storage Fresh crisp fresh dates effect. The results showed that the preservation of propolis coating could significantly reduce the weight loss rate and the rot index of the fresh-cut crisp jujube, maintain the hardness of the fresh cut crisp jujube, inhibit the decrease of soluble solids content, titratable acid content and Vc content, and increase the respiratory intensity Large, can significantly delay the aging of the round and crisp jujube postharvest, effectively extend the storage and preservation of the crisp jujube, 1.5% propolis coating the best preservation effect.
