Abstract

The study aimed to investigate the effect of different polyethylene (PE) film packaging on the quality of Xueqing pear during 24 weeks cold storage at 0 ℃. Xueqing pears were packaged with 0.03 mm PE film, 0.06 mm PE film, microporous film, respectively, and stored at 0 ℃ for 24 weeks. The quality changes of Xueqing pears were then analyzed. After 24 weeks storage at 0 ℃ , the quality of Xueqing pear packed with microporous film was the best, its sensory evaluation, weight loss, firmness, soluble solid, titratable acid, vitamin C and soluble sugar content were 7.0, 1.65%, 24.36 N, 10.93%, 0.107%, 6.68 mg/100 g, 4.61%, respectively. Taken together, film packaging effectively inhibited the increase of weight loss and delayed the decrease of sensory evaluation and content of VC, soluble solid, soluble sugar and titratable acid of Xueqing pear during cold storage. The quality of Xueqing pear packed with microporous film was the best.
