Effect of 50% CO_2 and 100% N_2 Shock Treatment on the Quality Changes of Chinese Chestnut (Castanea mollissima Blume) during Shelf-life

LIANG Li-song,WANG Gui-xi(Research Institute of forestry, CAF;Key Laboratory of Tree Breeding and Cultivation, State Forestry Administration,Beijing 100091,China)  
Chinese chestnut (Castanea mollissima Blume, cv. Yanchang ) stored 180 days at 0℃ were treated with 50%CO_2 or 100%N_2 for 5days or 10days to investigate the quality changes of chestnut during shelf-life. The result indicated that compared with other treatments, 50%CO_2 shock treatment decreased the sprouting rate and rot rate of chestnut significantly, and maintaining quality during shelf-life. High N_2 treatment increased the sprouting rate of chestnut, and can not contorl chestnut decay effectively during shelf-life. Chestnut treated with 50%CO_2 or 100%N_2 showed higher content of starch and lower content of soluble suger than control,but there was no significant effect on proten content.Chestnut with shock treatment in 50% CO_2 for 5 days had the better quality during shelf-life.
