  • This study was performed to evaluate the physicochemical and quality characteristics of bread with Enteromorpha intenstinalis added. In order to compare the physical and organoleptic properties, 1 to 4% of E. intenstinalis powder was mixed with the flour. Among the physical characteristics of the dough, the absorption ratio in the farinogram and the degree of attenuation increased with increasing amounts of E. intenstinalis powder, whereas the development time, dough stability, the degree of extension, the degree of resistance, and R/E became reduced. In the amylogram, there was no difference in the gelatinization starting temperature among the samples, but the maximum viscosity gradually increased according to increasing amounts of E. intenstinalis powder. Also, a sensory evaluation was carried out in terms of acceptability (color, flavor, moistness, tenderness, mouth feel, and overall acceptability). Taken together, the 2% treatment showed the highest evaluation values, as compared to the other treatments.

  • This study was conducted to evaluate the meat quality of pork produced by feeding fermented rice bran (FRB) (10 to 20%). In the proximate composition analysis there were no significant differences, but the FRB treated groups showed a tendency for higher moisture content and a lower fat content. There were no significant changes found in the physicochemical property analysis, except for cooking loss and water holding capacity, which are the most important factors for estimating meat quality. The cooking loss of the FRB pork was significantly lower than that of the control group (p<0.01). The water holding capacity of the 20% FRB roup was higher than that of the control group (p<0.01). The shear force value of the 20% FRB group was also higher than that of the control group, but the 10% FRB group showed no difference from the control group. The total free amino acid volume of the meat increased, depending on the volume of FRB added. The contents of glutamic acid, glycine, and alanine, which are important factors for taste and flavor, were higher in the FRB groups an the control group. In the sensory analysis, the FRB groups showed high scores for color, aroma, flavor, juiciness, taste, and overall acceptability. Taken together, adding FRB to the feed improved the quality of pork.

  • Quality characteristics of tofu as affected by addition time (before or after coagulant) and the amount (0, 3, 6, and 9%) of astringent persimmon fruit (Diospyros kaki T. cv. Cheongdobansi) powder added were investigated. Yield and sensory acceptability were higher in tofu prepared by adding persimmon before than after adding the coagulant. The yield of tofu with added persimmon was higher than that of the control. The L value of the tofu decreased as the amount of added persimmon increased. Hardness, chewiness, and crispness of tofu made with 6% persimmon were higher than those of the others. DPPH radical scavenging activity tended to increase as persimmon concentration increased but no significant difference was observed between the 3% and 6% added persimmon treatments. A sensory evaluation showed no significant differences in aroma, beany, astringency, and texture. However, the 9% sample had the significantly lowest score for overall acceptability. Thus, astringent persimmon powder (3-6%, before coagulant addition) can be utilized as an additive during tofu processing.

  • Onions were treated with different amounts of sulfur (S) during cultivation and examined for their physicochemical properties and flavor. Onions cultivated without S application were the control group; the treatment groups were grown in soil that had been pretreated with S and received additional S applications or four times before harvest. As the number of S applications increased, the levels of crude protein, quantified with total nitrogen; ash, approximating total amounts of minerals; and dietary fiber of the onions tended to increase. The mineral compositions also improved, with noticeable increases in the levels of Mg, K, Fe, and Zn. In particular, the reducing capacity of the onions increased appreciably (p<0.05), without increases in the levels of S-containing compounds such as thiosulfinate or S-containing amino acids. Nevertheless, the spicy hot taste and flavor, which is generated mainly from S-containing compounds, were perceived more strongly in the onions that had received more S applications.

  • The changes in fat acidity of brown rice and eating quality of rice during long term grain storage of unhulled rice were evaluated for the government managed rices. The Tongil type rice grains had consistently significantly lower fat acidity during three and half year storage than the Japonica type rice. On sensory evaluation of the fresh milled cooked rice the eating quality of the long term stored rices, 1987, 1988, and 1989 produce Tongil did not differ much each other even though increase in fat acidity by year of storage. The Japonica rices produced in 1989 and 1990 in different locations and stored there also did not differ much in eating quality. The grains stored in storehouses of super grade did not differ significantly from those stored in the first grades, but the grains stored (4 $^{\circ}C$, RH 50%) grains have kept the eating quality almost same as the fresh grains even after two and half years. A higher degree of milling did not improve significantly the sensory taste of cooked rice of the grains long term stored.

  • This study was carried out to investigate the changes in microflora, enzyme activity and sensory quality of four kinds of cheonggukjang during fermentation. Three different kinds of cheonggukjang were prepared with germinated soybeans using rice straw, Bacillus natto, B. natto plus Aspergillus oryzae, and the last one was prepared with non-germinated soybeans using rice straw. The pH values of cheonggukjang prepared with germinated or non-germinated soybeans increased up to 36 hr of fermentation and then decreased. The number of bacteria and molds increased significantly up to 24 hr of fermentation and then leveled off during fermentation. Acidic and neutral protease activities of all cheonggukjang continuously increased significantly during fermentation. ${\alpha}$- and ${\beta}$-Amylase activities of cheonggukjang decreased slightly during fermentation except cheonggukjang prepared with germinated soybeans using the mixed culture. The number of microflora, protease and ${\alpha}$-amylase activities were highest in cheonggukjang prepared with germinated soybeans using B. natto plus A. oryzae. The results of the sensory evaluation revealed that for overall acceptability, the cheonggukjang prepared with germinated soybeans using B. natto plus A. oryzae was similar to the cheonggukjang prepared with non-germinated soybeans using rice straw.

  • The behaviour of shrimp in response to the trap was much influenced by the type, size and the dimensions of entrance as well as physiological and ecological conditions. The entry and the escape behaviour of shrimp to the model trap were observed in accordance with netting materials, baits, type and slope of entrance, and gathering response were also investigated on the odour of bait extracts in the aquarium from June to August, 1983. Entering shrimp to the circular entrance was significantly more than to the triangular or the square; however, no differences were found in the entry behacior among netting materials i e., P. A, P. E. and cotton. According as the slope of entrance was increased its angle from 0$^{\circ}$ to 90$^{\circ}$, number of entering shrimp was decreased; however, number of escaping shrimp at 30$^{\circ}$or 60$^{\circ}$ with time was fewer than at 0$^{\circ}$ or 90$^{\circ}$. Gathering responses of shrimp on the odours were more sensitive to the flesh of mackerel or the shrimp than to the pickled anchovy, or the pettitioes, while no differences were found between another bait extracts, i e., the shrimp and the flesh of mackerel, the short-necked clam and the horse mackerel, the flesh and the viscera of mackerel.

  • This study was performed to evaluate the quality change of pork patties containing silkworm powder and vegetable worm (Paecilomycis japonica) stored for 9 days at $5^{\circ}C$. pH values were higher in treatment groups than that in controls by storage day 6. L (lightness) and a (redness) value were decreased with increasing addition of silkworm powder and vegetable worm powder in pork patties (p<0.05). However, b value (yellowness) was increased with increasing addition amounts of the silkworm powder and the vegetable worm powder (p<0.05). Water holding capacity (WHC) of pork patties was not affected by the silkworm powder and the vegetable worm powder, while pork patties containing 0.4% silkworm powder (T2) showed low cooking loss (p<0.05). Pork patties containing either silkworm powder and vegetable worm alone or a combination of them showed lower lipid oxidation value than that of control (p<0.05). Sensory preference of pork patties was decreased with increased of storage days. The overall acceptance was higher in treatment groups than at control groups at the initial day (p<0.05), yet no significant difference was found during storage. From these results, 0.4% silkworm powder decreased not only cooking loss but also lipid oxidation of pork patties. Also, no adverse effect was found in water holding capacity (WHC) and sensory preference of pork patties. Therefore, the silkworm powder and the vegetable worm powder could be useful to pork meat product industry as additives.

  • The purpose of this study was to examine obstetrical & gynecological health status and body composition for married female immigrants. The participants were 154 immigrant women living in Busan. Data were collected from July 2008 to July 2009 using a questionnaire and a bioelectrical impedance analysis tool (Inbody 720) for analysis of body composition. Most subjects were in the normal range for body composition, but some of those who answered the questionnaire had experienced some gynecological problems such as dysmenorrhea, or irregular menstruation. There was a significant difference in experiences with in vitro fertilization, pregnancy and abortion according to age and in premensturaion syndrome, as well as differences in regulation of menstruation during the past year, leukorrhea odor, experiences in in vitro fertilization, and delivery and breastfeeding according to nationality. There were significant differences in body mass index and waist-hip ratio according to age, as well as differences in percent body fat, body mass index and waist-hip ratio according to nationality. There were also significant differences in body mass index and waist-hip ratio according to period of stay in Korea. Procreative care protocols concerning married female immigrants' characteristics should be developed.
