Abstract: The chestnut(Castanea mollissima Blume.’Yanchang’)was studied for its change in the contents of sugar,starch,protein and ethanol,the rate of rot and sprouting after water-curing treatment for different time(Bubble,Bubble+1 d,Bubble+2 d and Bubble+3 d)and then stored at 0±0.5 ℃ in holed PE bags.The results showed that the rate of rot and sprouting in shelf-life are significantly reduced.The soluble sugar and protein are kept well and starch hydrolyzable rate is slowed down by" Bubble+2 d" treatment during cold storage.All the data have shown that" bubble+2d" treatment improved the quality of chestnut during storage.
