壳寡糖对羽衣甘蓝芽苗硫代葡萄糖苷及抗氧化活性的影响
Effects on Glucosinolates and Antioxidant Activity of Chitooligosaccharides on Kale Sprouts
摘要
Abstract
In order to investigate the effect of chitooligosaccharides(COS)on the growth of kale sprouts and to provide a reference for the rational application of chitooligosaccharides in the production of sprouts,this study used Jingyu 1 as the test material,and applied different concentrations of COS(25,50,75,100 mg/L)to the seeds after germination to observe the effects of COS on the growth indexes,content of glucosinolates and antioxidant ca-pacity.The results showed that total phenolics content,total flavonoids content,total glucosinolates content,myrosi-nase enzyme activity and DPPH free radicals scavenging rate of 75 mg/L COS-treated kale sprouts showed an up-ward trend,and the differences were significant with the control,with increases of 25.99％,17.99％,29.68％,141.88％,and 2.51％,respectively;the yield and total phenolics content,total flavonoids content,sodium content,boron content and myrosinase enzyme activity,of 100 mg/L COS-treated kale sprouts were also enhanced according-ly and differed significantly from the control,increasing by 15.21％,21.29％,22.47％,15.97％,32.63％,97.71％,respectively.After correlation analysis,it could be obtained that the yield of sprouted seedlings was signifi-cantly and positively correlated with the content of carotenoids,total phenolics,and total flavonoids and DPPH free radicals scavenging rate.In conclusion,chitosan treatment could increase the yield of kale sprouts,improve the nu-tritional quality and antioxidant capacity of sprouts,and increase the edible value of sprouts.关键词
