Purpose: This study investigated the quality characteristics of traditional and commercial red pepper pastes (Gochujang) for development of traditional red pepper pastes. Methods: Proximate compositions, amino acid nitrogen contents, salt contents, color, viable bacteria, and inorganic substance contents of 19 traditional and three commercial Gochujang were investigated. Results: Analysis of proximate compositions showed huge differences between the samples. For moisture content, six kinds of traditional Gochujang did not meet the standard of the food codex. Contents of moisture, fat, and protein were significantly higher in traditional than commercial Gochujang. However, carbohydrate content was higher in commercial than traditional Gochujang, and thus calories were also higher. The amino nitrogen contents of the three kinds of traditional Gochujang did not meet the standard of the food codex. Salt contents and color were not significantly different between traditional and commercial Gochujang. In the microbiological analysis, total bacteria counts were higher in traditional than commercial Gochujang. The number of B. cereus did not exceed the standard of the food codex in all samples. S. aureus and fungi were not detected in any samples. In the inorganic substance analysis, inorganic substances contents in Gochujang were in the order of Na, K, Mg, and Ca. Overall, Na, K, Mg, and Ca were more abundant in traditional than commercial Gochujang. However, due to wide variations in inorganic substance contents of traditional Gochujang, there were no significant differences between traditional and commercial Gochujang. Conclusion: For the development of traditional Gochujang, quality standardization is considered necessary.

Purpose: This study aimed to investigate the quality characteristics of traditional and commercial soybean pastes (Doenjang) for development of traditional soybean pastes. Methods: Proximate compositions, amino acid nitrogen contents, pH, acidity, salt contents, chromaticity, viable bacteria and inorganic substance contents of nineteen traditional and three commercial Doenjang were investigated. Results: Analysis of proximate compositions indicated a significant difference between samples. In moisture content, D10 did not meet the standard of food codex. The contents of moisture, fat, protein and ash were slightly higher in traditional than commercial Doenjang. However, the carbohydrate content was 2-fold higher in commercial than traditional, and thus, the calories were also higher. The amino nitrogen content was lower in commercial than traditional Doenjang. pH, acidity and salt contents of Doenjang were pH 4.67-6.15, 1.53-3.29%, and 9.01-18.78%, respectively. pH and acidity showed no significant differences between traditional and commercial Doenjang, however, salt contents were significantly higher in traditional than commercial Doenjang. In case of chromaticity, the averages of L, a, b values were higher in traditional Doenjang. In microbiological analysis, total bacteria counts were higher in traditional than commercial Doenjang. The number of Bacillus cereus in D12 and D19 exceeded the standard of food codex. Staphylococcus aureust was undetected in all samples. The number of fungi varied widely between samples, with no detection in five traditional and all commercial Doenjang. Results of inorganic substance analysis indicated that contents of inorganic substances in Doenjang were in order of Na, K, Mg and Ca. Overall, Na content was higher in traditional Doenjang. Contents of inorganic substances showed wide variations in traditional Doenjang. Conclusion: For the development of traditional Doenjang, quality standardization and ensuring safety are considered necessary.

This study was conducted to evaluation the quality of meals served in elementary school based on nutrient contents and food diversity . A questionnaire was mailed to school foodservice dietitians requesting one week menus for April and October . Menus served in 388 schools from each province and from major cities in Korea were analyzed. Mean nutrient contents per meal of persons served, and food expenses per meal. Mean percentages of energy from fat was 20.2% , and was significantly l different by foodservice system. When nutrient contents were converted to amount per 1, 000kcal, all were higher than that calculated from RDA except calcium, iron, and Vitamin A. Most of these were not significantly different according to area, foodservice system, the number of persons served, and food expense per meal. Compared to 1/3 of RDA for children , many meals provided lower amounts of energy, Vit A, VitB2, and Ca. More than half of the meals provided less iron than 1/3 RDA for 10-12 years girls. Using the highest values of RDA for the elementary school age group as evaluation, criteria nutrient adequacy ratios(NAR) were lowest for Ca(0.61), Vit A(0.57), and iron(0.77). The mean adequacy ratio(MAR) was 0.86. Mean numbers of food items and dishes per meal were 15.3 and 5.1 , respectively. 66.3% of the meals provided three food groups of grain, meat, and vegetable. Except for the number of different food items served per meal, the aspect of food diversity was similar to that of nutrient contents. There was significant positive correlation between mean number of different food items served per meal and nutrient content . In summary , schools in small cities and rural areas than those in large cities, schools adapting commissary or joint management than those or density. Also the more food groups served per meal, the higher the nutrient content per meal . In summary , schools in small cities and rural areas than those in large cities, schools adapting commissary or joint management than those adapting conventional foodservice system, schools serving smaller number of persons, and schools with higher food expenses provided higher energy contents and food diversity.

Amygdalin contents of the seeds, endocarps, and mesocarps from three peach cultivars (i.e., Stone Peach, Hikawa Hakuho, and Bakhyang) were measured at three stages of fruit development (stone-hardening, fruit enlargement, and ripening). The peach samples were dried and defatted with a Soxhlet apparatus, reflux extracted with methanol, and analyzed using reverse phase high-performance liquid chromatography. During all fruit development stages, the amygdalin contents in the seeds were higher than those in the endocarps and mesocarps. The amygdalin contents of the Stone Peach were comparatively higher than the Hikawa Hakuho and Bakhyang (P<0.05). Further, the amygdalin contents during ripening were very low or not detected. Overall, the amygdalin contents of the three peach cultivar samples (seed, endocarp, and mesocarp) increased until the fruit enlargement stage and either remained constant or decreased during ripening.

The purpose of this study was to examine the relationship between the regular selling price and nutrient contents of foods used for special medical purposes in Korea. This study investigated the regular selling price and nutritional composition of 114 enteral nutrition (EN) foods on the manufacturer's internet homepage. The average price of the total products was 1,156.0 won/100 mL. The price of foods used for calorie and nutrient supplementation (CNS) was significantly higher compared to that of the other EN food types (p<0.01). With respect to the nutritional content per 100 mL of the product, EN foods for CNS had significantly higher contents of energy, protein, 5 minerals, and 7 vitamins than the other EN food types. On comparing the nutritional contents of foods according to the price, the balanced nutrition foods showed significantly higher contents of energy, carbohydrate, protein, 3 minerals, and 7 vitamins in high-priced products than in low-priced foods. Summarizing these results, foods for CNS were approximately twice as expensive as the other EN foods, and the energy, protein, mineral, and vitamin contents were also high. Balanced nutrition foods had higher nutrient contents in high-priced products, which showed the relationship between the product price and nutrient content.

Forty plants used as tea materials were chosen for determining the contents of total phenolics, selenium (Se), ${\beta}-carotene$, ${\alpha}-tocopherol$ and ascorbate. Total phenolics and ascorbate contents were analyzed colorimetrically. The Se contents were measured by hydride-atomic absorption spectrometry. The contents of ${\beta}-carotene$ and ${\alpha}-tocopherol$ were simultaneously determined by high performance liquid chromatography using separate detectors, UV for ${\beta}-carotene$ and FL for ${\alpha}-tocopherol$ analyses. The contents of these antioxidants were as follows (per 100 g dry plant); Contents of total phenolics in green tea leaf, black tea leaf, oolong tea leaf and instant coffee were about 7 g and the Se contents in corni fructus and arrowroot were found to be about $4{\mu}g$, which were the highest among all plants used. Contents of ${\beta}-carotene$ in eucommiae cortex, persimmon leaf and green tea leaf were 8587, 6222 and $3652\;{\mu}g$ respectively. The persimon leaf contained the highest ${\alpha}-tocopherol$ content (33 mg) and then followed by eucommiae cortex (26 mg), green tea leaf (16 mg) and black tea leaf (13 mg) in order. Ascorbate contents were found to be high in green tea leaf (199 mg) and black tea leaf (117 mg).
