The paper aims to study the effects of 4 packaging films on the storage quality of flowering cabbage to provide basis for prolonging the shelf life of flowering cabbage.The flowering cabbage was respectively packed with LDPE, PVDC, PVC and PE, and stored at 4 ℃. The physiological and biochemical indexes such as respiratory intensity, MDA content and peroxidase activity of flowering cabbage were measured every 3 days during storage. During storage of 0~6 days, the inhibitory effect of LDPE, PVDC and PVC on respiration intensity of flowering cabbage was superior to PE. The hardness of flowering cabbage of LDPE, PVC and PE groups was slightly high and close to that of the fresh. The results showed that four packaging film scould effectively inhibit chlorophyll degradation and phenylalanine ammonia-lyase activity, and enhance peroxidase activity. During postharvest storage of flowering cabbage, the four packaging films could delay the aging process of flowering cabbage and improve its quality. LDPE was the most suitable packaging film for flowering cabbage, followed by PVC. When the shelf life of flowering cabbage was≤6 days, the comprehensive quality of flowering cabbage was the best.
