Abstract
In this study, proximate composition, crude fiber, reducing sugar, free sugars, organic acids, minerals and amino acids of Platycodon grandiflorum seeds were analyzed to evaluate its nutritional value. Moisture, crude protein, crude fat, crude ash and carbohydrate contents of seeds were 6.97, 26.05, 27.46, 3.78 and 35.74%, respectively. Crude fiber of 6.31% and reducing sugars of 1.54% were also determined. Sucrose(1,661 mg/100 g) and lactic acid(1,224 mg/100 g) were most abundant free sugar and organic acid, respectively. Both phosphorus and potassium were main minerals that contained more than 700 mg in 100 g seeds. Amino acids analysis of 100 g seeds showed that glutamic acid(3.45 g), arginine(2.51 g), aspartic acid(1.66 g), leucine(1.29 g), lysine(1.10 g), alanine(1.05 g) and glycine(1.04 g) were abundantly contained in order, while others were less than 1 g.
