침지 전처리 및 광조건에 따른 양배추 새싹 추출물의 항산화 활성 능력

다국어 초록 (Multilingual Abstract)

Cabbage (Brassica oleracea var. capitate) is a vegetable crop from Brassicaceae, mainly grown in Asia. It is a popular food ingredient worldwide due to its abundance of nutrients and bioactive compounds. In this study, cabbage seeds were subjected to pre-soaking treatment and different light conditions, and the total flavonoid content (TFC), total polyphenol content (TPC), and antioxidant activity of the sprouts were compared. Cabbage seeds exposed to dark conditions after pre-soaking treatment showed the greatest increase in sprout biomass, including shoot length (16.3 mm) and fresh weight (346.8 mg/plant). The hypocotyls of sprouts grown under blue light after pre-soaking treatment turned purple. Sprouts grown under dark conditions and blue light after pre-soaking treatment had excellent TFC (125.1 and 135.2 mg·NE·g−1, respectively), TPC (130.1 and 126.2 mg·TAE·g−1, respectively), DPPH radical scavenging activity (1.11 and 1.25 mg·mL−1, respectively), and ABTS radical scavenging activity (0.97 and 1.12 mg·mL−1, respectively). Therefore, cabbage sprouts grown under different light conditions after pre-soaking treatment have better growth, bioactive compounds, and antioxidant activity. This sprout cultivation method can help improve the quality of various sprout vegetables and produce functional foods.
