Abstract

The study was carried out to improve the red pepper quality and reduce the drying period by using different covering film materials inside plastic film houses. The mean temperature of drying bed was higher under polyethylene (PE), polypropylene (PP) non-woven fabric covering than under non-covering. Mean relative humidity was lower under PP non-woven fabric covering. Drying period was 2 to 3 days shorter by PP non-woven fabric covering than control in August, while 5 days shorter in September. The marketability was higher (90.5%) under PP non-woven fabric covering than under non-covering in cv. ‘Daemyung’, and PE non-woven fabric treatment was higher (96.2%) in cv. ‘Keumtab’. Hunter's color of dried red pepper was some high black shade net treatement. Sugar content of dried red pepper was higher (6%) in cv. ‘Daemyung’ than cv. ‘Keumtab’ and capsanthin was high in cv. ‘Keumtab’. However sugar, capsaicin and capsanthin contents did not differ significantly by covering material treatments.

고추 하우스 건조 시 피복 재료를 처리하여 건조기간을 단축하고 품질을 향상시키고자 본 시험을 실시하였다. 건조상의 평균온도는 PE 또는 PP부직포 처리에서 높고 습도는 PP부직포 처리에서 낮아 고추 건조에 유리하였으며 PP부직포 피복시, 건조기간은 무처리에 비해 8월에는 2∼3일, 9월에는 5일 빨랐다. 평균 상품률은 대명' 품종의 경우 PP부직포 처리에서 90.5%, 금탑'품종은 PE 부직포 처리에서 96.2%로 가장 높았다. 색도는 흑색차광망 처리에서 다소 높은 경향을 보였으며 8월에 비해 9월에 건조한 고추가 L, a, b 값이 높았다. 건고추의 주요 성분 중 당은 대명' 품종이 금탑'에 비해 약 6% 많았고 capsanthin은 금탑' 품종이 높게 나타났다. 그러나 피복재 처리에 의한 당함량, capsaicin, capsanthin 성분에 있어 처리 간 유의성은 없었다.
