Abstract: The effects of chitosan, licorice extract and their mixture on physiological and biochemical changes of Laiyang pear fruits during at room temperature ( (22 ± 2 ) ℃) were investigated. The results showed that all the three preservative treatments could significantly (P< 0.05) inhibit the respiration intensity, decrease weight loss rate and decay rate, and delay the reduction of vitamin C, titratable acidity and soluble solids when compared with the control group.

Key words: Laiyang pear, licorice extract, chitosan, preservation
