The results showed that the formula of 3% sucrose + 50 mg/L citric acid + 600 mg/L vitamin C + 20 mg/L 6-BA could effectively maintain the water balance of the cut flower, prolong the vase life of the cut flower to 16.4 d, and maximize the flower diameter and the crown height.展开更多
以1℃冷库贮藏后硬度为3.0 kg·cm^(-2)的‘金艳’猕猴桃果实为试材,采用微孔保鲜袋、不同厚度PE保鲜袋、气调保鲜袋及气体湿度调节包装袋6种不同处理对出库后的‘金艳’猕猴桃进行自发气调处理,以市售保鲜袋为对照,分析其对果实货...以1℃冷库贮藏后硬度为3.0 kg·cm^(-2)的‘金艳’猕猴桃果实为试材,采用微孔保鲜袋、不同厚度PE保鲜袋、气调保鲜袋及气体湿度调节包装袋6种不同处理对出库后的‘金艳’猕猴桃进行自发气调处理,以市售保鲜袋为对照,分析其对果实货架期及其内在品质的影响,以期筛选出适合猕猴桃货架期保鲜的气调包装。结果表明:气调包装处理可有效延长猕猴桃果实货架期,随处理时间延长,果实硬度、可滴定酸含量逐渐降低,失重率、腐烂率、可溶性固形物含量、固酸比逐渐升高,果实不断后熟软化,风味品质得以提升,但不同处理保鲜效果存在差异。果实品质各项评估指标综合评价与感官评价分析,果实货架期延长、果实品质提升效果依次为气体湿度调节包装袋>气调保鲜袋>0.04 mm PE保鲜袋>0.02 mm PE保鲜袋=0.03 mm PE保鲜袋=微孔保鲜袋>CK,气体湿度调节包装袋货架期整体表现更为优异,有效延长了果实货架期,维持了较好的果实品质。因此,兼具气体、湿度调节的包装袋在猕猴桃货架期保鲜中具有更广阔的应用前景。展开更多
