  • The rheological properties of soybean paste suspensions as affected by concentrations and heating were studied. All suspensions of soybean paste showed thioxotropic plastic behavior. The concentrated suspensions below the ratio of water to soybean paste, 1.25 exhibited Figure-eight phenomena which were presented by two Intersections of the up curve with the dorm curve of shear rate. The dilute suspension (soybean paste: water=1:2) showed H type hysteresis loop at low temperature. But increasing the heating temperature above $60^{\circ}C$, the hysteresis loop exhibited a Figure eight phenomenon. Consistency index of the suspensions increased remarkably by heating and showed the highest value around isoelectric point of the protein. It was suggested that the proteinous nitrogen might be the main component taking part in viscous behavior under different pH and heat treatment.

  • The study was carried out to determine the effect of storage property and qualities on soybean sauce and paste by adding different amount of pyroligneous liquor obtained by sujpercritical fluid extraction(SFE). Purified pyroligneous liquor obtained by SFE at 4$0^{\circ}C$/110 bar contained p-cresol, o-cresol and m-cresol food sterilizers, but no toxic substances such as tar, scorched, furfuraland and monophenol. Thus pyroligneous liquor was considered to be suitable as natural food preservative. In case of soybean sauce, pyroligneous liquor was tested to determine the potential of natual food preservative to prevent flim formation on soybean ksauce 15days at 3$0^{\circ}C$. Increasing amounts of purified pyroligneous liquor added to soybean sauce prevented film forming yeasts. In case of paste, pyroligneous liquor was tested to determine the potential of natural food preservative to inhibit browning on paste 60 days at 3$0^{\circ}C$. Purified pyroligneous liquor added to paste inhibited brown pigment. As a result, purified pyroligneous liquor offered a promising way of improving the quality and storage property of soybean sauce and paste.

  • The purpose of this study was to investigate the storage stability of mayonnaise containing a different emulsifier and various levels of soybean paste powder. The mayonnaise with egg yolk as an emulsifier is E group according to the amount of soybean paste powder addition of 0%(E1), 3%(E2), 6%(E3) and mayonnaise with soy milk as an emulsifier is S group with soybean paste powder addition of 0%(S1), 3%(S2), 6%(S3). Storage stability of mayonnaise was determined during storage at $30{\pm}5^{\circ}C$ for 8 weeks. The peroxide value, TBA value, acid value of mayonnaise with addition of 6% soybean paste powder was significantly lower than that of 0% and 3% addition. The turbidity decreased according to storage period. The viscosity of mayonnaise was increased with increasing amount of soybean paste powder. Base on these results, addition of soybean paste powder in the mayonnaise improved oxidation stability during storage period.

  • This study conducted surveys on perception and utilization of Korean soybean paste targeting 493 women from their 20s to 60s residing in Daegu. Most subjects married (75.3%), were part of a nuclear family (84.8%), had more than a high school diploma (95.8%), had a career (47.9%), lived in an apartment (68.4%), had a total household income of 5 million won or more (38.1%), and had monthly food expenses more than 0.5 million won and less than 1 million won (42.2%). Regarding perception, 'rich nutrition' was the most commonly held perception in subjects in their 60s (4.4), followed by 'good taste' in subjects in their 40s (4.3). Regarding reasons for consumption 'healthy' was highest in subjects in their 60s (47.3%) and 40s (45.6%) and 'delicious' in subjects in their 20s (56.1%). Regarding how to make it, subjects in their 60s responded 'know for sure' (57.1%), while only 2% of 20s responded the same. Subjects in their 50s and 60s had a higher ratio of answering 'know' while 20s and 30s 'don't know', For preparation methods, subjects in their 20s (53.1%) and 30s (41.4%) answered 'buy at the market', subjects in their 40s (68.9%) 'get from family or relatives' and subjects in their 60s (47.3%) 'make by one's own'. For preservation method, subjects in their 20s and 30s answered 'preserve in refrigerator', the 60s tend to answer 'preserve in jangdokdae'. Buying at the market was most common in subjects in their 20s (36.1%) and 30s (28.5%) and the reason was 'convenient' (39.6%). The place of purchase was 'in large supermarket or department store' (78.5%). For the future consumption pattern, 'increase in consumption of commercialized product (44.0%)', subjects in their 60s answered 'keep making at home' while subjects in their 30s and 40s answered 'keep making at home or buying product half and half'. According to the above study results, women living in Daegu region were aware of excellence of traditional soybean paste. However, due to changes in residential circumstance and lack of knowledge about the recipe, they did not make. They receive soybean paste t from family, relatives or bought in the market, which indicates the continuous decrease in home-made soybean paste. Therefore, due to the expanding social participation of women, the product market is expected to increase. I think it is important to develop traditional commercial soybean paste in the traditional way to improve the traditional flavors.

  • Effects of green tea-soybean paste on weight-changes and serum lipid profiles in rats fed high fat diet were investigated. Sprague-Barley male rats divided into five groups were fed five different diets for 10 weeks: B group, basal diet H group, high fat-diet containing 0.5% cholesterol+15% lard H-S group, high fat diet containing soybean paste H-0.6GS group, high fat diet containing 0.6% green tea-soybean paste H-4GS group, high fat diet containing 4% green tea-soybean paste. H group showed highest weight gain (p<0.05). Addition of green-tea soybean paste to high-fat diet significantly decreased weight gain, H-4GS group showing highest weight loss (p<0.05). No significant differences in food efficiency ratio and total food intake were found among groups. Liver weight of H group was highest. Addition of green tea-soybean paste to high fat diet significantly reduced liver weight (p<0.05, Table 2). Concentrations of glucose, uric acid, bilirubin, and total protein were similar among all group. Mean GPT values of H-4GS group were significantly different from these of H- and H-S groups (p<0.05). H-S, H-0.6GS, and H-4GS groups had significantly lower triglyceride and total cholesterol, and higher HDL than H-group (p<0,05). H-4GS group had significantly lower serum triglyceride than H-0.6GS group (p<0.05).

  • This study investigated preferences toward soybean-based foods and levels of dietary isoflavone intake in female adults living in Daegu. In order to determine the subjects' attitudes toward soybean-based foods their degrees of recognition and preference along with intake frequency were examined. To estimate their isoflavone intake levels, a food frequency questionnaire and the 24-hour recall method were used. The average age, height, weight, and BMI of the subjects were 47.3 years, 159.6 cm, 56.4 kg, and 22.1 kg/$cm^2$, respectively. And their mean energy, protein, dietary fiber, calcium, and sodium intakes were 1,871.9 kcal, 81.1g, 23.2 g, 604.7 mg, and 5.07 g, respectively. The average amount of isoflavones consumed from soy foods was 29.49 mg/day(daidzein 13.14 mg/day and genistein 16.35 mg/day) as assessed by food frequency questionnaire, and by the 24-hour recall method the average amount was 22.97 mg/day (daidzein 10.10 mg/day and genistein 12.87 mg/day), showing that the food frequency questionnaire assessment amount was 6.52 mg higher than that by 24-hour recall method. The major food sources of the isoflavones were soybean paste and soybeans. For the subjects' degrees of recognition of soybean food, soybean paste received the highest score among the items. The results also showed that the most preferred soybean-based foods were soybean paste stew and soybean paste soup. Furthermore isoflavone intake was significantly higher in the postmenopausal women than in the premenopausal women. Overall, these data help elucidate the patterns and determinants of soy food consumption and also provide an assessment of dietary soy isoflavone intake in Korean women.

  • The aim of this study was to investigate the quality properties of beef jerky replaced salt with soy sauce, red pepper paste, and soybean paste. The quality properties of beef jerky including final water activity ($a_w$), moisture content, pH, color, shear force, total plate counts, thiobarbituric acid reactive substance (TBARS) values, and sensory evaluations were investigated. The sliced beef samples were marinated in salt (control), soy sauce (T1), red pepper paste (T2), and soybean paste (T3) for 24 h and then dried at $70^{\circ}C$ for 6-8 h. The water activity of finished beef jerky varied from 0.72 to 0.70. The water activity for control and T1 samples decreased more rapidly as drying proceeded up to 6 h. The samples with salt replacement showed a lower pH and lightness than the control (p<0.05). The T1 sample showed a significant decrease in total plate counts after 21 d of storage (p<0.05). The TBARS for all treatments increased with storage days (p<0.05). The TBARS were significantly lower in T2 and T3 samples compared to control and T1 until 21 d of storage (p<0.05). The samples with salt replacement showed a lower intensity of saltiness than the control. Sensory evaluations found that the replaced soy sauce of beef jerky samples had better overall acceptability scores than the other treatment samples. It was concluded that replacing salt with soy sauce can delay lipid oxidation and enhance the sensory acceptance of beef jerkies.
