Abstract

Highlights: Laser light improved the nutritive value of common and tartary buckwheat sprouts. Laser irradiation boosted the antioxidant capacity of both buckwheat sprout types. Tartary buckwheat sprouts were more responsive to laser light treatment. Laser light-treated buckwheat sprouts pose induced anti-inflammatory activities. Abstract: Buckwheat sprouts are rich in several nutrients such as antioxidant flavonoids that have a positive impact on human health. Although there are several studies reported the positive impact of laser light on crop plants, no studies have applied laser light to enhance the nutritive values of buckwheat sprouts. Herein, the contents of health-promoting minerals, metabolites and enzymes as well as the antioxidant and anti-inflammatory activities were determined in laser-treated (He–Ne laser, 632 nm, 5 mW) common buckwheat (CBW) and tartary buckwheat (TBW) sprouts. Out of 49 targeted minerals, vitamins, pigments and antioxidants, more than 35 parameters were significantly increased in CBW and/or TBW sprouts by laser light treatment. Also, laser light boosted the antioxidant capacity and anti-inflammatory activities through inhibiting cyclooxygenase-2 and lipoxygenase activities, particularly in TBW sprouts. Accordingly, laser light could be recommended as a promising method to improve the nutritional and health-promoting values of buckwheat sprouts.
