Abstract

The objective of this study is to evaluate the effects of various conditions of additional light on the growth and polyphenol contents of broccoli sprouts. For the purpose of an efficient investigation, an experimental equipment which was emulated a commercial production system was developed. The effects of the combination of different wavelengths of light sources were evaluated on the hypocotyl length, fresh and dry weight and polyphenol contents in broccoli sprouts using this experimental system. Forty eight hours of additional light in the following two types of combinations: 1) white fluorescent light and black light; 2) red fluorescent light and black light, significantly enhanced polyphenol content, while showing much less effect on shortening hypocotyl length and no effect on dry weight in comparison with the commercial condition. These results suggest that additional light supplement combined with black lights (UV-A) leads to an increase of polyphenol content and an enhancement of antioxidative activity in broccoli sprouts with only little negative effects in appearance and yield.
