Abstract：Yali pear is vulnerable to be suffered from carbon dioxide injury. At present, for storing the fruit of Yali pear it hash 't been packed with any film but instead wrapped in paper (normally artificial parchment paper). But fruit wrapped with paper suffers from heavy weight loss and skin shriveling. In this study,effects of packaging with micro-perforated LDPE (low-density polyethylene)film on the storage quality of Yali fruit were investigated. For the control Yali fruit were wrapped with artificial parchment paper. During storage the carbon dioxide concentration inside the headspace of the packages was in the range of 1.1% to 3.2% for the normal LDPE film packs and 0 to 0.6% for the package of micro-perforated LDPE film. Re-suits showed that the packages with micro-perforated film reduced the incidence of core and flesh browning,fruit weight loss and skin shriveling. The fruit quality attributes such as TSS (total soluble solids)and TA (total titratable acidity)were similar among the 3 treatments. Packing Yali fruit in micro-perforated LDPE film bags was a much better method than the presently used method of paper wrapping.
