Optimization of Cultivation and Storage Conditions on Red Cabbage Seed Sprouts

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.
