TECHNOLOGY FOR MAINTAINING QUALITY OF CHESTNUT DURING STORAGE USING CHLORINE DIOXIDE GAS TREATMENT

摘要

The present invention relates to a technology for maintaining quality of a chestnut during storage using chlorine dioxide gas treatment. In particular, when a chlorine dioxide gas is treated onto a chestnut at a concentration of 15 ppmv for 20 minutes, the chestnut is stored for 8 weeks, and then the number of aerobic bacteria is measured. As a result, compared to a control group, the number of aerobic bacteria is reduced by 30%. The number of yeast and fungi is reduced by 20%. A weight decrease rate is reduced by 50%. A decomposition rate is also reduced by 75%. It is confirmed that there is not a change in apparent chromaticity caused by chlorine dioxide gas fumigation. After a chestnut is obtained under a treatment condition of a chlorine dioxide gas, the apparent quality of the chestnut is maintained. During storage, microbial safety is ensured, and damage by harmful insects is reduced. Accordingly, the present invention can be useful as a chestnut storage method for reducing a decomposition rate.;COPYRIGHT KIPO 2017
