不同厚度聚乙烯保鲜袋对贵长猕猴桃的贮藏效果

摘要

The effect of single-layer (PE ) freshness protection bags with different thickness (0.03 mm,0.04mm and 0.07 mm)on storage of Guichang kiwifruit was studied at 0~1℃ to provide a reference for storage property of kiwifruit.The results showed that single-layer (PE)freshness protection bag with 0.04 mm can inhibit respiration intensity of kiwifruit obviously and delay fruit senescence,and its VC content,soft rate,rotted rate and commodity rate of kiwifruit are 104.23 mg/100g,10%,10% and 90% after 3 months separately.%为提高贵长猕猴桃果实的耐贮性提供参考，在0～1℃条件下，进行了0．03 mm、0．04 mm 和0．07 mm 厚度聚乙烯（PE）单层保鲜袋包装对贵长猕猴桃贮藏效果的影响试验。结果表明：采用0．04 mm聚乙烯（PE）单层袋贮存可明显抑制贵长猕猴桃果实的呼吸强度，延缓果实衰老，贮存至3个月时，果实各项生理指标仍较好，其中维生素 C 含量达104．23 mg/100g，果实软果率和腐烂率均为10％，商品率达90％。
