激光微孔膜包装复合1-甲基环丙烯处理对茭白采后木质化的影响
Effect of Laser Microporous Film Package Combined with 1-Methylcyclopropene Treatment on Postharvest Lignification of Water Bamboo Shoots
摘要
Abstract
Lignification leads to a sharp decline in the postharvest edible value of water bamboo shoots(Zizania latifolia).This study reveals the effect of laser microporous film(LMF)packaging combined with 1-methylcyclopropene(1-MCP)treatment on the lignification of water bamboo shoots at(4±1)℃.The results indicate that,compared to the control group,LMF+1-MCP treatment effectively inhibits lignin accumulation(thereby preserving whiteness),reduces the consumption of soluble solids and sugars,and suppresses respiration and weight loss.These effects are primarily attributed to the treatment's ability to scavenge intracellular reactive oxygen species(O·-2、H2 O2)and reduce MDA accumulation—mechanisms achieved by synergistically enhancing the activity of antioxidant enzymes(SOD,APX,CAT)while simultaneously suppressing key enzymes in the lignin biosynthetic pathway(PAL,C4H,4CL,CAD,LAC,POD).Our studies show that LMF+1-MCP treatment inhibits the activity of lignin synthesis-related enzymes by inhibiting nutrient loss and reducing the accumulation of reactive oxygen species,and ultimately delays the lignification process.The study provides new insights for delaying the postharvest lignification process of water bamboo shoots,and provides an innovative technical solution for the storage and preservation of water bamboo shoots.关键词
