  • Nutritional compositions in edible portion of Castanopsis cuspidata seeds were investigated. Moisture content of Castanopsis cuspidata was 24.72 (Wt. %), crude protein was 2.19% (Wt. %), crude lipid was 0.83% (Wt. %), ash was 1.04% (Wt. %), and carbohydrate was 52.63% (Wt. %) in Castanopsis cuspidata seeds. Major amino acids were glutamic acid, aspartic acid, arginine and histidine, and minor ones were alanine, serine, proline, and valine. Sucrose was the highest content of free sugar in the seed. Major fatty acids were linolenic acid (18:3), palmitic acid (16:0) and oleic acid (18:1). Major minerals were P, K, Mg, Zn and Ca at the level of 88.31, 26.00, 13.20, 10.90, and 3.93 mg/100 g, respectively.

  • This study investigated the nutritional components and antioxidant activity of dry bitter melon (Momordica charantia L.). The moisture, crude protein, crude fat, crude ash, carbohydrate, and ascorbic acid contents of dry bitter melon were 6.10%, 3.31%, 1.08%, 2.31%, 87.20%, and 908.84 mg/100 g, respectively. Potassium was the most abundant mineral, followed by Mg, P, Na, Ca, Zn, Cu, and Mn, which means dry bitter melon was an alkali material. Regarding amino acid contents, dry bitter melon was rich in arginine, urea, asparagine, ${\gamma}-aminobutyric$ acid, and alanine. Total polyphenol and total flavonoid contents of dry bitter melon extract were 36.08 mg gallic acid equivalents/extract g and 15.66 mg tannic acid equivalents/extract g, respectively. The $IC_{50}$ value for 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity was 9.81 mg/mL for dry bitter melon ethanol extracts.

  • Nutritional evaluation of the proposed supplementary foods (high nutrition-low cost foods) for children were conducted for the ‘Wonseong County Comprehensive Nutrition Program’ in Korea. Proximate composition, mineral, vitamin and amino acid composition were determined and also protein efficiency ratio(PER) was evaluated for the propsed formulas which were recommended as CSS (corn-soybean-sesame blend)-3, CSS-4 and BSS (barley-soybean-sesame blend)-4 in previous study. Protein and caloric contents of the formulas were around 18% and 400 Kcal/100 g respectively, and they have reasonable contents of mineral and vitamin. Amino acid score (83-89) and PER (2.33-2.36) of the proposed formulas were considered to be in adequate range of protein quality for feeding the target group in Wonseong County area.

  • This study were carried out to analyze nutritional ingredients of pre-inoculation and post-harvest Flammulina velutipes media. pH, moisture content, total carbon(T-C), total nitrogen(T-N), crude protein, crude fiber, and crude fat content on the 8 raw materials using Flammulina velutipes bottle cultivation medium, and after sterilization(pre-inoculation) and post-harvest medium was analyzed. This result is expected to be utilized as the basis for recycling post-harvest media.
