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 capacity.The results showed that total phenolics content,total flavonoids content,total glucosinolates content,myrosinase enzyme activity and DPPH free radicals scavenging rate of 75 mg/L COS-treated kale sprouts showed an upward 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 accordingly 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 significantly 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 nutritional quality and antioxidant capacity of sprouts,and increase the edible value of sprouts.
