中文摘要: 探究不同透性包装材料对鲜切京葱贮藏期间品质变化的影响。试验采用 3 种不同透性的薄膜对鲜切京葱进行 包装,4 ℃下贮藏 7 d,每隔 1 天测定鲜切京葱的可溶性固形物、袋内顶空气体组分、硬度、颜色、风味、感官及菌落总数的 变化。采用主成分分析法对所测定指标进行综合分析。结果表明,PE1 相较于其余两种包装材料,可以很好地维持鲜切 京葱的品质,其透氧率(OTR)、透二氧化碳率(COTR)和透水率(WVTR)分别为(1 460.58±151.14) cm3/(m2·d·0.1 MPa),

Abstract:The different permeability of packaging materials effect on quality of fresh cut green onion during storage were explored. Fresh cut green onion with 3 different permeability film were packaged and storaged at 4 ℃ for 7 days. The soluble solid matter, bag headspace gas components, hardness, color, flavor and sensory and the total number of colonies were determined every other day. The principal component analysis was used for comprehensive analysis of determination indicators. The results showed that PE1 could maintain the fresh cut green onion quality very well compared to the other two kinds of packaging materials, which the oxygen permeation rate(ORT), carbon oxidation permeation rate(COTR)and water permeation rate(WVTR)respec- tively were:(1 460.58±151.14) cm3/(m2·d·0.1 MPa),(6 218.63±149.90) cm3/(m2·d·0.1 MPa),(0.98±0.013)gm·(m2·day·0.1 MPa).
