摘要: 研究壳聚糖、海藻酸钠、乳酸链球菌素和溶菌酶4种天然保鲜剂对樱桃番茄贮藏保鲜效果的影响,分析比较4种天然保鲜剂处理对樱桃番茄的感官品质、质量损失率、硬度、呼吸强度、VC含量、可溶性固形物含量以及超氧化物歧化酶(SOD)活性等生理生化指标的变化。结果表明:壳聚糖涂膜处理的樱桃番茄,感官效果最好,在4℃条件下贮藏15d后,果实的腐烂指数为0.231,质量损失率仅为7.34%,VC含量为26.4mg/100g,可溶性固形物含量为8.9%,呼吸强度显著低于其他处理组,保鲜效果最佳。

Abstract: The effects of chitosan, alginate, nisin and lysozyme on fresh-keeping of cherry tomatoes were compared by determining their sensory quality, weight loss, hardness, respiration rate, vitamin C content, soluble solids content and SOD activity during the storage. The results showed that chitosan coating gave the best preservation effect, determined 15 days after coating and storied at 4 ℃. The rot index was 0.231, weight loss rate was 7.34%, vitamin C content was 26.4 mg/100 g, soluble solids content was up to 8.9%, and respiration rate was significantly lower than cherry tomatoes treated by other reagents.

Key words: cherry tomatoes, fresh-keeping, coating, chitosan
