Fresh-keeping effects of packaging materials on fresh-cut pineapple
摘要
Abstract
The fresh-keeping effect of different kinds of packaging materials on fresh-cut pineapple was studied. Pineapple were chosen,peeled and cut to wedges（1. 5～2. 0cm chick）. Dipped in 0. 5% citric acid solution for 3min,the pineapple wedges were packaged in plastic trays and covered with polyethylene（PE）film,high-density polyethylene（HDPE）bags and polyethylene-polypropylene（PE/PP）composite bags respectively,or packaged in polyester（PET）cup and covered with a PET top having a 3mm diameter hole,and then stored at 5℃ for 10 days. The fresh-cut pineapples were measured at 0,2,4,6,8,10 day respectively. The results showed that PE/PP and PET packaging materials with low gas-permeability could reduce weight loss,browning,juice leakage,electrolyte leakage and dehydroascorbic acid loss more than PE and HDPE films did,but all the packaging materials did almost the same effects on the acid and TSS contents.关键词
