이산화염소 및 저온 플라즈마 가스 살균 및 MAP 처리가 파프리카의 저장 중 품질과 미생물학적 변화에 미치는 영향 (Effect of Chlorine Dioxide, Cold Plasma Gas Sterilization and MAP Treatment on the Quality and Microbiological Changes of Paprika During Storage)

초록

This study was conducted to investigate the effect of packaging methods and sterilization treatment on stor ability and microbial control in paprika fruits. When treated with chlorine dioxide gas for 3, 6, and 12 hours and cold plasma gas for 1, 3, and 6 hours, and then packed in a carton box and stored in a 8 ± 1o C chamber for 7 days, chlorine dioxide treated 12 hours and plasma treated 6 hours was prevented the development of E·coli and YM(yeast and mold).
Accordingly, the control was treated with chlorine dioxide for 12 hours and plasma for 6 hours, packed using a carton box and 40,000 cc·m-2·day-1·atm-1 OTR film (MAP), and stored in a 8 ± 1o C chamber for 20 days. Fresh weight loss rate during storage was less than 1% in the MAP treatments, and the visual quality of the MAP treatments was above the marketability limit until the end of storage. There was no difference in the contents of oxygen, carbon dioxide, and eth ylene in the film. In the case of firmness, the chlorine dioxide treatments was low, and the Hunter a* value, which showed chromaticity, was highest in the Plasma 6h MAP treatment. Off-odor was investigated in the MAP treatments, but it was very low. The rate of mold growth on the fruit stalk of paprika was the fastest and highest in the chlorine dioxide treated box packaging treatments, and the lowest in the chlorine dioxide treated MAP treatments at the end of storage. The aer obic count in the pulp on the storage end date was the lowest in the plasma treated box packaging treatments, the lowest number of E·coli in the chlorine dioxide treated MAP treatments, and the lowest yeast & mold in the chlorine dioxide treated box packaging treatments. As a result, for the inhibition of microorganisms during paprika storage, it is considered appropriate to treat plasma for 6 hours before storage regardless of the packaging method.
