Abstract

The purpose of this study was to estimate the growth promoting effects and improvement of antioxidant activity of the soybean sprouts treated with Chlorella sp. culture solution. The soybean sprout treated with 0.1% and 0.2% Chlorella sp. culture solution was significantly increased the length (more than 43.0%), the thickness (more than 0.5~0.7 mm), fresh weight (more than 2.9~3.7 g) compared to non-treated control in vitro. In organic soybean sprouts farm, the 0.2% chlorella culture solution applied to mass culture of soybean sprout and the fresh weight of soybean sprouts increased by more than 25% and the yield was very high as 598.33% compared to untreated control. In addition of sensory test, there is no fishy odor and better crunchy texture and nutty flavor for the treatment soybean sprouts compared to untreated soybean sprouts. Particularly, free-radical scavenging activity (DPPH) and superoxide dismutase activity (SOD) of the soybean sprouts were significantly increased more than 26.1% and 40.4%, respectively by treated with 0.1% and 0.2% Chlorella culture solution. Consequently, the treatment of chlorella culture solution to grow soybean sprouts is also promoting quality and antioxidant activity as well as promoting the growth of sprouts. Therefore, chlorella is considered to be worth as functional materials for high-quality sprouts grown.
