Abstract
The work aims to study the effects of modified atmosphere packaging and micro-perforated film on the storage quality of grapes to provide basis for prolonging the shelf life of grapes. The fresh grapes were respectively provided with modified atmosphere packaging with the proportions of O2 (5%)+CO2 (5%)+N2 (90%) (MAP1) and O2 (10%)+CO2 (10%)+N2 (80%) (MAP2), and PE ginseng nylon co-extrusion micro-perforated film (MPF) and stored at 4 ℃. The changes of grape hardness, pH value, soluble solids, titratable acid, ascorbic acid, chroma and weight loss rate were measured every 48 d, and the sensory evaluation was made. During storage of 0-12 days, the experimental results showed that, the preservation effect was as follows: MPF>MAP2>MAP1> reference group. During postharvest storage of grapes, the three kinds of packaging can delay the aging process of grapes when the shelf life of grapes is ≤12 days. PE ginseng nylon co-extrusion micro-perforated film has the best preservation effect.
