摘要:

为探究微酸性电解水(SAEW)与ε-聚赖氨酸盐酸盐(ε-PLH)复合处理对鲜百合鳞片的保鲜效果,本试验将新鲜百合鳞茎人工分瓣,随机设置对照组(CK,无菌蒸馏水浸泡)和复合处理组(MIX,30 mg·L-1 SAEW浸泡10 min后,再用0.2% ε-PLH浸泡10 min),测定了百合鳞片在4 ℃贮藏过程中的理化指标。结果表明,MIX处理显著(p<0.05)降低了鲜百合鳞片的失重率,提高了鲜百合鳞片的白度和可溶性固形物含量,并显著抑制了丙二醛的积累。此外,MIX处理显著提升了鲜百合鳞瓣的1,1-二苯基-2-三硝基苯肼(DPPH)自由基清除能力,抑制了其多酚氧化酶活性,延缓了维生素C的降解。综上,SAEW与ε-PLH复合处理有效延缓了鲜百合鳞片的品质劣变,可为预制净菜的绿色保鲜提供技术参考。

Abstract:

To investigate the freshness-keeping effect of slightly acidic electrolyzed water (SAEW) and ε-poly-L-lysine hydrochloride (ε-PLH) on fresh lily bulb petals, fresh lily bulbs were manually segmented into petals and randomly divided into a control group (CK, sterile distilled water immersion) and a combined treatment group (MIX, 30 mg·L-1 SAEW immersion for 10 minutes followed by 0.2% ε-PLH immersion for 10 minutes) in this study. And the physicochemical parameters of lily bulb segments during storage at 4 ℃ were measured. The results showed that the MIX treatment significantly (p<0.05) reduced weight loss,increased the whiteness and soluble solids content, and effectively inhibited malondialdehyde accumulation. Additionally, the MIX group significantly enhanced DPPH radical scavenging activity, suppressed polyphenol oxidase activity, and delayed the degradation of ascorbic acid in the petals. In conclusion, the combined SAEW and ε-PLH treatment efficiently delayed the quality deterioration of fresh lily bulb petals, providing a technical reference for the green preservation of fresh-cut vegetables.
