Abstract

This study was carried out to find the optimal conditions for red cabbage seed sprouts in terms of their physicochemical and sensory qualities by electron-beam irradiation, cultivation and storage using the response surface methodology (RSM). Moisture content ($R^2$=0.9638) was affected by irradiation dose and cultivation time. Total phenolics content ($R^2$=0.9117) was mainly affected by irradiation dose, but carotenoid content ($R^2$=0.8338) was affected in the order of irradiation dose, cultivation time and storage time. Sensory properties were also affected by irradiation dose, and thus scores decreased as irradiation dose increased. The optimum conditions estimated by superimposing total phenolics content and overall acceptance were 2.2-3.8 kGy of the irradiation dose, 3.0-4.0 days of cultivation and 2.0-3.0 days of storage.

반응표면분석법을 이용하여 적양배추 종자의 전자선 처리조건과 재배조건에 따른 새싹채소의 이화학적 및 관능적 품질특성을 분석하여 유통에 적합한 최적조건을 모색하였다. 수분함량의 경우 회귀식의 $R^2$가 0.9638이었고 조사선량 및 재배기간에 많은 영향을 받고 있었다. Total phenolics 함량은 회귀식의 $R^2$가 0.9117이었고 조사선량에 많은 영향을 받았으며, carotenoid 함량($R^2$=0.8338)의 경우 조사선량, 재배기간, 저장기간의 순으로 조건 변수의 영향력이 작용하였다. 관능적 품질 역시 전자선 조사선량에 가장 크게 영향을 받아 선량의 증가에 따라 관능평점이 감소하는 경향을 보여주었다. 재배 및 저장조건의 최적화를 위해 total phenolics 함량 및 전반적 기호도를 superimposing한 결과 최적조건은 조사선량 2.2-3.8 kGy, 재배기간 3.0-4.0일 및 저장기간 2.0-3.0일 범위로 예측되었다.
