Abstract

Nutritional compositions of Korean traditional actinidia (Actinidia arguta) cultivars, such as Otumsense, Chiak, and Skinny green, were investigated as high value-added food substances. Among minerals, K content of three cultivars was the highest, and P, Ca, and Na contents were relatively higher than those of other minerals. Contents of essential amino acids were analyzed as follows: Otumsense (198.48 mg/100 g), Chiak (413.50 mg/100 g), and Skinny green (270.07 mg/100 g). Total amino acids of Chiak were the highest among the three cultivars, and major amino acids of the three cultivars were glutamic acid and aspartic acid. Analysis of fatty acids showed that major fatty acids were palmitic acid as a saturated fatted acid and α-linoleic acid as an unsaturated fatty acid in the three cultivars. Glucose and fructose were major free sugar constituents in the three cultivars. Total free sugar content of Otumsense was relatively higher than others. Finally, niacin and vitamin B6 of Skinny green (1.55 mg/100 g, 1.92 mg/100 g) were the highest among the cultivars. However, β-carotene as a vitamin A precursor (3.82 μg/100 g) and vitamin C as a natural antioxidant substance (47.18 mg/100 g) of Otumsense cultivar were the highest. ? 2014, J Korean Soc Food Sci Nutr.
