Abstract
As a series of study on the hygienization and long-term storage of dried red pepper and red pepper powder using gamma irradiation, water activity and fatty acid composition were monitored for stored samples. In proximate composition of dried pepper, moisture contents were 21.75 % in pericarp and 9.30% in seed, and crude fats were 7.20% (fresh wt.) in pericap and 22.50% in seed, respectively. Proximate components were stable against irradiation up to 10 kGy. Moisture contents and water activity of packaged samples in PE (0.1mm)/polycloth (whole pepper) and in nylon
감마선 조사에 의한 건고추와 고춧가루의 위생화 및 장기저장을 위한 일련의 연구를 수행하면서, 감마선 조사후 저장조건 별 시료를 대상으로 수분활성과 지방산 조성의 변화를 검토하였다. 건고추의 부위별 일반 성분 조성에서 수분함량은 과피 21.75%와 씨 9.30%였고, 조지방 함량은 과피 7.20% (신선물 기준)와 씨 22.50%였으며, 일반성분은 감마선(max. 10 kGy) 조사에 의해서도 유의적인 변화가 없었다. 건고추와 고춧가루는 PE (0.1 mm)/폴리마대 및 nylon
