Abstract: The contents of nutritional and functional components of walnut kernel pellicle were analyzed preliminarily by using conventional and instrumental analytical methods.Results showed that the contents of protein,carbohydrates,fat,vitamin B1,vitamin B2,and minerals such as phosphorus,zinc and calcium are 11.03 g/100 g,7.74 g/100 g,20.20 g / 100 g,0.205 mg/100 g,0.05 mg/100 g,and 442 mg/100 g,29.20 mg/100 g and 23.20 mg/100 g respectively.The contents of vitamin B1,phosphorus and zinc are as 1.37,1.50 and 13.46 times as those of walnut kernel repectively.The contents of polyphenols and flavonoids are 1.038 g / 100g and 0.744 g/100 g,as12.51 and 1.78 times as those of walnut kernel respectively,which suggests that walnut kernel pellicle has high nutritional and health values.
