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.

Key words: slightly acidic electrolyzed water, ε-poly-L-lysine hydrochloride, fresh lily bulb petals, freshness-keeping effect
