  • Proximate compositions of black rice and antioxidative effects of its methanol extract on refined perilla oil were investigated. Black rice seeds were composed of water 12.4%, crude protein 7.9%, crude fat 2.2%, crude fiber 1.0%, ash 1.4% and N-free extract 75.1%. The hexane and 80% methanol fractions in yields were higher than 80% ethanol and chloroform. In AOM(active oxygen method) test, antioxidative effects of black rice added to the refined perilla oil was increased with dose-dependent fashion in concentration of the black rice extracts. Among several extracts tested, 80% aqueous methanol extract showed the highest antioxidative activity, followed by hexane, chloroform, in that order. The peroxide value and TBA value for their antioxidation stability were also lower than that of control. This result was similar to that of AOM test.

  • Mixed feeds and their components are a very diverse matrix compared to other agricultural products worked on with NIRS classically. On a database of mixed feeds and their components (n=2.500) universal PLS calibrations and “local” calibrations were compared. The results from validation (n=600) show the potential of the calibrations and their limitations. Crude protein, crude fiber, crude fat, sugar and starch are predicted with SEPs of 0.6%, 1%, 0.3%, 1% and 1.5%, respectively. Ash content of 15% and more in several mixed feeds or components as well as rare components limit the use of NIRS for routine analyses.

  • The principal objective of this study was to determine the quality characteristics of tofu prepared with the addition of skate (Raja kenojei) powder. The moisture, crude ash, carbohydrate, crude protein, and crude lipid contents of the used skate powder were 5.34%, 14.15%, 1.90%, 76.60%, and 2.08%, respectivly. The yield rate of the tofu did not differ significantly with the level of added skate powder; however, significant reductions in pH and a significant increase in acidity were observed. The L and b values of the tofu decreased with increases in the amount of added skate powder in the formulation, whereas the a values increased directly with the amount of added skate powder. Furthermore, hardness was increased significantly as the level of skate powder increased. In terms of overall acceptability, the preferred tofu samples were the control and the group to which, 1.0% skate powder was added.

  • Baked black soybean has great nutritional value, so it is a great potential ingredient in cake. To find an acceptable ingredient ratio, baked black soybean powder was to wheat flour in different experimental groups. The control was pure wheat flour, and the experimental groups had 0 (control), 10%, 20%, 30%, and 40% baked black soybean powder added. The baked black soybean powder consists of moisture (4.88%), crude protein (34.46%), crude fat (11.35%), crude ash (4.84%), and carbohydrates (44.47%). The specific gravity, spreadability, and baking loss increased with an increase in the amount of baked black soybean powder, but specific volume decreased. The 'L' and 'b' chromaticity values of a sponge cake decrease with increased amounts of added baked black soybean powder. The texture becomes more hard and stuff with added baked black soybean powder, but springiness decreases. A sensory test found the best experimental group to be that of 20% powder added.

  • This study was conducted to investigate the quality characteristics of sun-dried salt prepared with added Cheongyang hot pepper juice(CPJ). The moisture, crude protein, crude lipid, and crude ash contents of the CPJ were 84.36%, 2.27%, 1.41%, and 0.67% respectively. The moisture content, yellowness, capsaicin, and dihydrocapsaicin of sun-dried salt increased according to the level of added CPJ, whereas the NaCl, pH, lightness, and redness value increased. The sensory evaluation results showed that preferences for the sun-dried salt increased as CPJ, approached their optimum value and decreased as they exceeded optimum levels. Consequently, the proposed optimum level in the ingredient formulation for manufacture of the standard sun-dried salt was 30% CPJ, as based on analyses. Ultimately, this study was expected to contribute to the commercialization of sun-dried salt of high quality.

  • The quality characteristics of doenjang which contained Astragalus membranaceus water extracts were investigated in this study. The contents of moisture, crude protein, and crude fat were not significantly different in the doenjang which contained Astragalus membranaceus water extracts. The crude ash content was significantly higher in the doenjang which contained Astragalus membranaceus water extracts. The doenjang which contained Astragalus membranaceus water extracts showed higher a-value. Antioxidative activity was evaluated by using the thiobarbituric acid reaction products assay and peroxide value. Antioxidative activity and hydrogen donating activity were increased in doenjang which contained Astragalus membranaceus water extracts. Doenjang which contained Astragalus membranaceus water extracts showed no differences with traditional doenjang in sensory profiles of taste, color, flavor, and overall quality. These result showed the applicability and higher quality of doenjang which contained Astragalus membranaceus water extracts.
