Abstract

|
The nutritional components of astringent persimmons according to growing region (five different regions) and cultivar (Daebong and Bansi) were analyzed. The analyzed nutritional components were proximate compositions, insoluble and soluble dietary fibers, vitamin C, carotenes (β-carotene and lycopene), free sugars (glucose, fructose, and sucrose), sugar alcohols (xylitol, sorbitol, and mannitol), minerals (Na, Mg, K, Ca, Mn, Fe, and Zn), organic acids (tartaric acid, malic acid, citric acid, and succinic acid), tannic acid, total phenolic compounds, and flavonoids. Daebong and Bansi, which are representative cultivars of astringent persimmons grown in Korea, exhibited significant differences in nutritional components. Insoluble dietary fibers, β-carotene, fructose, sucrose, mannitol, potassium, malic acid, succinic acid, and total phenolic compounds were present at higher levels in Daebong as compared to Bansi. On the other hand, Bansi was rich in moisture, crude protein, vitamin C, Ca, Mn, tartaric acid, and flavonoids. Nutritional components were highly influenced by growing region. Daebong grown in region A was greater in β-carotene, sorbitol, mannitol, zinc, and total phenolic compounds among the all other tested persimmons grown in five different regions. The crude protein, Na, Ca, Mn, tartaric acid, and flavonoids were highest in Bansi grown in E region.
