  • This study was conducted to investigate the effect of baking on the physicochemical and sensory properties of white pan bread with red wine (RW). RW was substituted for water at four levels (0, 19, 38 and 63%). For bread crumb color, lightness decreased with increasing levels of RW, whereas redness and yellowness increased (p<0.05), in proportion to RW levels. Compared to control bread, specific volume of breads added with RW was decreased. The degree of dough raising power decreased significantly depending on the amounts of RW. The hardness of control bread was $87.35g/cm^2$ while the hardness of breads with RW ranged from 85.37 to $94.19g/cm^2$. Hardness, cohesiveness, springiness and gumminess of breads added with RW showed higher scores than the control group. In the sensory evaluation, the highest flavor and taste preference scores were observed in bread containing 38% RW, whereas the lowest score was observed in bread with 63% RW. Accordingly, the quality of bread can be improved by addition of 38% RW substituted for water.

  • The purpose of this study was to investigate the preferences, consumption, and eating frequencies of housewives for commercialized traditional basic side dishes. The investigators visited 18 food markets and questionnaires were distributed to 464 housewives in the Busan area. The number of basic side dishes being sold at the markets were in the order of seasoned dried radish (17 markets; mk), salted garlic stalk (15 mk), braised black soy beans (14 mk), braised peppers and dried anchovies (13 mk), and braised lotus roots (12 mk). The housewives' order of preferences was for stir-fried dried anchovies, braised peppers and dried anchovies, braised seasoned beef, salted perilla leaf, and perilla leaf kimchi equal to seasoned sea lettuce, respectively. The order for eating frequency was stir-fried dried anchovies, braised peppers and dried anchovies, salted perilla leaf, and perilla leaf kimchi, respectively. Salted perilla leaf, perilla leaf kimchi, braised crab preserved in soy sauce, salted bean leaves, seasoned dried radish, and seasoned crab were either occasionally or frequently purchased by over 40% of the women. However, the reasons they did not purchase these products included: the excess use of chemical seasonings, unsanitary, unreliable cooking process, unreliable the origin, and high price, in the respective order. If the commercialized traditional basic side dishes were improved to eliminate these problems, 52.2% of the housewives would buy the products, and 65.6% anticipated increasing their use of these products in the future.

  • Quality characteristics of white breads added with different levels of jujube extracts were investigated. Addition of jujube extract significantly decreased L-value, and increased a and b-values. Addition levels up to 70% did not have significant effects on the texture of breads. Significant increases in the hardness, chewiness, and gumminess were observed in 100% jujube-added group. Additive levels over 50% jujube showed good sensory scores compared with control bread in color, flavor, taste, and general palatability. Textural property increased with increasing amount of jujube extract. Results showed substitution of 50-70% jujube extract for water improved bread quality.

  • The characteristics of ice cream, such as type-keeping viscosity, turbidity and stability of emulsion, were studied with the different composition of fatty acid of monoglyceride. The effect of saturated fatty acid of monoglycerides such as monolaurin, monomyristin, monopalmitin and monostearin on the characteristics of ice cream did not show any difference. The unsaturated fatty acid of monoglycerides, however, such as monocaprin and monoolein, was drastically enhanced the viscosity and easily happened the overrun of ice cream mixture which were resulted in the condensation of the fat droplet. Also the condensed fat droplet had the sterical network-structure. When the ratio of monostearin and monoolein becomed about 30:70, especially, it was confirmed the curdling of fat sphere increase to a maximun so that type-keeping and heat stability of ice cream were improved.

  • This study performed a microbiological hazard analysis, which is required for the application of HACCP (Hazard Analysis Critical Control Point) system to Pteridium aquilinum and Platycodon grandiflorum. The manufacturing process was made by referring to the typical manufacturing process. Based on microbiological hazard analysis, grandiflorum root contained $6.2{\times}10^3CFU/g$ of bacteria, which has the largest amount of bacteria among the agricultural materials. On the other hand, microbiological hazard analysis of the raw materials and after the disinfecting process of confectionery showed a safe result. A microorganism test of the manufacturing environment and workers suggests that the microbiological hazard should be reduced through systematic cleaning, disinfection and accompanied by personal hygiene based on hygiene education for workers.

  • We optimized braising time to improve the storage quality of braised kidney beans. The beans were prepared with different heating times between 25 and 50 min. and then stored at $10^{\circ}C$ for 20 day. Physical, chemical, microbiological, and organoleptic quality indices were monitored throughout storage. Longer braising times yielded products with lower concentrated brine coverage. Bis resulted in higher soluble contents and slightly lower water activities. Excessive heating time exposed the kidney beans to air and caused rapid microbial growth on the surfaces of the beans, which negatively affected product quality. The longest heating time of 50 min. also resulted in a large increase in product hardness. A braising time of 30 min. was best for preservation, as good sensory quality was mainatained.

  • BACKGROUND/OBJECTIVES: The leaves of Moringa oleifera (MO) and Moringa stenopetala (MS) commonly grown in Ethiopia possess potential nutritional and medicinal value. The aim of this study was to evaluate the nutritional and functional characteristics of the dried leaf powder from two Moringa species to develop sustainable nutritional supplements for Ethiopians from locally grown plant sources. MATERIALS/METHODS: Freshly harvested and air-dried MO and MS leaves were authenticated and the nutritional contents, such as protein, ash, lipids, and selected vitamins and minerals, were analyzed using standard analytical procedures. Amino acid compositions were also determined by an amino acid analyzer. Nine-week-old mice were randomly divided into four groups to investigate the anti-obesity effects of Moringa. The first group was fed a basal diet, the second group a high-fat diet, and the others were fed a high-fat diet containing 0.1% Moringa leaf powder from each species. After seven weeks, serum indices related to lipid profiles from each mouse were analyzed. RESULTS: The present study revealed high protein (28-29%) and ash (7-11%) contents. Glutamic acid, aspartic acid, proline, and leucine were the most abundantly found amino acids in both species. The predominant minerals in the leaf powder were calcium (826-1,530 mg/100 g), potassium (794-904 mg/100 g), and magnesium (286-431 mg/100 g). Pyridoxine (475.06 mg/100 g) and vitamin E (34.2 mg/100 g) were found only in MS. Niacin was found only in MO at 32.21 mg/100 g, whereas ascorbic acid was found in both species (3.89 and 6.19 mg/100 g dry weight for MO and MS, respectively). The results of the animal study showed that mice on a high-fat diet containing 0.1% MO leaf powder alleviated the elevation of cholesterol, triglycerides, and low-density lipoprotein cholesterol induced by the high fat diet. MO was more effective than MS in preventing hypercholesterolemia and fat deposition. CONCLUSION: The findings in this work confirmed that Moringa leaves of both MO and MS possessed high nutritional value but MO was better at preventing the harmful effects of the high-fat diet than MS.

  • Objectives: Screen time refers to the time spent using screen media, such as televisions, smartphones, computers, or tablets. Excessive exposure to screen media has been reported to negatively impact young children's health and development, including overweight, short sleep duration, and language delays. This study examined the association of screen time and mealtime media use with dietary behaviors among preschool children. Methods: A cross-sectional survey was conducted on parents of children aged three to five years using the online questionnaires of the Nutrition Quotient for Preschoolers (NQ-P) and the Dietary Screening Test (DST). Data from 261 children's parents were analyzed. Results: Of the 261 children, 96.9% used screen media, 55.6% used screen media for two hours or more daily, and 30.7% were exposed to screen media during meals. The NQ-P scores were significantly lower in the children with longer screen time and mealtime media use. Children who used screen media for two hours or more and those exposed to screen media during meals consumed kimchi less frequently and confectionery and sugar-sweetened beverages more frequently than children who used less than two hours and were not exposed to screen media during meals. In addition, they were more likely to be picky about food, refuse to eat, and less likely to feed themselves than children with shorter screen time and no mealtime media use. Conclusions: This study reported an association between unhealthy dietary behaviors, feeding difficulties, and screen time and mealtime media use among preschool children. Further research should explore effective strategies for reducing children's screen time.

  • This study aims to investigate the quality characteristics of breads with the addition of sweet pumpkin powder. Farinogram showed that the absorption rate of the dough decreased, the development time and stability became shortened, and the degree of attenuation tended to be grown along with increasing the amount of pumpkin powder. From the amylogram, it was found that the gelatinization starting temperature and the maximum viscosity of pumpkin powder added dough seemed to be decreased as the amount of pumpkin powder was increased. Extensogram showed that there was a decrease in the degree of extension of the dough added with increasing the amount of pumpkin powder, while an increase in the degree of resistance and resistance/extensibility. The lightness (L value) and redness (a value) of bread was found to be decreased with increasing the amount of pumpkin powder, while the yellowness (b value) increased. In terms of the dough texture, for which the hardness, cohesiveness and gumminess of the dough were measured, there were no significant differences between groups, while the dough added with 8.0% pumpkin powder showed a significant decrease in the elasticity. The results of sensory evaluation showed that the highest score of color (p<0.05) and taste (p<0.05) were obtained from the bread added with 6.0% and 8.0% pumpkin powder, while the highest score of texture in control and 3.0% pumpkin bread. In addition, the highest score of flavor (p<0.05) and overall acceptance (p<0.05) were observed in bread added with 6.0% pumpkin powder. Upon the results of this study, it was assumed that the development of food products using pumpkin are prospective in response to health-oriented consumers.
