  • This study concerns designing effective fuzzy inference rules, which can be used to evaluate other experiment sets for sensory tests. The number of fuzzy inference rules might be determined by the fuzzy division of variables. For the more the number of fuzzy division does not mean the more effectiveness, the number of inference rules should be reduced to improve efficiency of inference engine of expert system. This study verified that its suggested method and inference rules are effective in comparison with the existing studies.

  • The purpose of this study was to investigate the effect of Opuntia ficus-indica var. Saboten powder on the quality of noodles. Noodles containing 04.5% of Opuntia ficus-indica var. Saboten powder were prepared for test the quality of mechanical and sensory characteristics. Moisture content of noodles with or without Opuntia ficus-indica var. Saboten powder was 32∼33%. In Hunter's color values of noodles of control, the lightness(L) was 74.21, redness(a) was -2.40 and yellowness(b) was 5.52. The lightness(L) of noodles was decreased by the increasing concentration of Opuntia ficus-indica var. Saboten powder. The redness(a) and yellowness(b) were increased by the increasing concentration of Opuntia ficus-indica var. Saboten powder. In mechanical characteristics of noodles, strength, hardness and brittleness were increased with increasing concentration of Opuntia ficus-indica var. Saboten powder. In sensory evaluation, color of noodles in C group(0.3%) and D group(0.5%) addded Opuntia ficus-indica var. Saboten powder were significantly higher score than control group(p<0.05). Overall, Noodle added 0.3% of Opuntia ficus-indica var. Saboten powder showed the highest preference in sensory evaluation.

  • This study was conducted to promote fish paste made with white poria cocos wolf powder as a food. The tested concentrations of the powder were 0, 1, 3, 5, and 7%. All the fish paste samples had 37% water content. For the Hunter color values of samples, L-values decreased but a- and b-values increased with increasing concentrations of the powder. In addition, the folding test scores of all samples were good (AA). In the texture tests, brittleness increased where as springiness decreased with increasing concentrations of the powder. In the sensory evaluations, color, flavor, hardness, and cohesiveness scores increased, and sleekness and oily taste scores decreased, with increasing concentrations of the powder. The fish paste containing 3% white poria cocos wolf powder (3WPWP) had the highest acceptance scores for appearance, flavor, taste, texture, and overall quality. These results suggest that white poria cocos wolf powder can be applied to fish paste to increase its quality.

  • Bacillus polymyxa No. 26이 생산하는 생전분 당화형 $\beta$-amylase를 쌀가루 반죽시 첨가하여 45$^{\circ}C$에 5시간 둔 후 증자하여 제조한 절편을 4$^{\circ}C$ 저온실에 40시간 동안 저장하면서 기계적 검사와 관능검사에 의하여 물성과 맛을 측정하고 효소 무 첨가의 경우와 비교하여 노화억제 효과를 조사하였다. 기계적 검사시 효소 무 첨가구의 경우는 40시간까지도 굳지 않아 노화되지 않았으며, 경도, 점착성, 씹힘성에서도 큰 차이를 보였다. 관능검사시에도 경도, 촉촉함성, 단맛에 있어서 효소 첨가효과가 크게 나타났으며 떡의 제조 시 효소의 이용으로 설탕첨가를 생략할 수 있고 소화성과 맛을 좋게하므로서 품질을 향상시킬 수 있었다.

  • The purpose of this study was to investigate the characteristics of beef jerky adding of many kinds of saccharides and three levels of green tea powder. Color and hardness were increased with the addition of green tea powder while tenderness was decreased. Moistureness Gf beef jerky added honey was higher than that of sugar, oligo saccharide. In color, the lightness was decreased with increasing concentrations of green tea Powder. Redness and yellowness values were increased. In measurement of texture, hardness were increased with the addition of green tea powder. The hardness of beef jerky by adding of honey appeared to be higher than that of sugar, oligo saccharide. Gumminess and brittleness were increased with the addition of green tea powder while springness was decreased. Springness in addition of 3% green tea powder was higher than control. The beef jerky added with 3% green tea powder and sugar had good overall perference.

  • Fuzzy reasoning was applied to sensory evaluation of cooked rice. A sensory attribute diagnostics was done in terms of tour kinds of attributes-texture, taste, odor and appearance which determine overall palatability. First, rating for the contribution level of each attribute to the overall palatability was asked as one of five scales-very important, important, moderate, slight and very slight. Secondly, the preference level of each attribute for a cooked rice sample was asked as one of five hedonic scales-excellent, good, fair, poor and very poor. Thirdly, the results of the scales were converted into fuzzy values and operated by fuzzy reasoning. Finally, the contribution and preference levels of the attributes were composed to infer the overall palatability of cooked rice sample.

  • The effects of defatting on sensory and instrumental characteristics of corn and mung bean starch gels during storage were investigated. The untreated and defatted starch gels stored at room temperature for 24 hrs and 72 hrs. The sensory characteristics of defatted corn starch gels were significantly different from untreated ones but the properties of defatted corn starch gels were similar to those of mung bean ones. Mung bean starch gels showed no changes in sensory characteristics by defatting. In the case of instrumental properties, there was highly significant in all characteristics between corn starch gels and mung bean starch gels, but firmness in defatted corn starch gel was similar as in mung bean starch gels.

  • This research was conducted to predict taste of barley kanjang using multiple regression analysis between taste components and sensory score. In the analysis of single correlation, the correlation coefficient of proline, alanine, Methionine, lysine, histidine, lavulinic acid, ${\alpha}$-ketogutaric acid was significant in 5% level. On the other hand, the taste of barley kanjang was not significantly effected by threonine, serine, cystein, phenylalanine, succinic acid, arabinose, xylose, and sucrose. It was impossible to measure taste of kanjang with barley bran to use simple correlation analysis. The 93% of barley kanjang taste was predicted using multiple regression analysis with taste components and sensory evaluation scores.

  • This study was performed to compare the pungency perception of Koreans with that of Australians by sensory evaluation using capsaicin and capsaicin-containing chilli powder. First, the sensory tests for various concentrations of capsaicin were carried out, and then capsaicin-containing chilli powder was added to water, porridge and noodle, and they were evaluated to find out the threshold concentrations of capsaicin in each medium. In the results, the pungency perception of Australians was higher in low concentrations of capsacin, while Korean perceived the pungency better in high concentrations, and the panels perceived hot taste better in water followed by porridge and noodle. The low concentrations of capsaicin was not easily perceived if it is contained in porridge or noodle.

  • 김치의 단맛을 내기 위하여 일반 제조에 이용괴고 있는 sucrose 대신 stevioside나 sorbitoal과 같이 당의 종류를 달리하여 제조한 김치의 이화학적 성분. 미생물의 변화 및 관능적 특서에 미치는 영향을 조사하였다 pH와 적정산도는 stevioside와 sorbitol이 첨가된 처리구가 sucrose 가 첨가된 처리구보다 산의 생성 억제효과가 있는 것으로 나타났다 총균수의 경우 전반적으로 당의 종류와 저장온도와는 관계없이 미생물의 생육 억제효과가 없는 것으로 나타났으나 젖산균의 경우 1$0^{\circ}C$에서는 균의 생육 억제효과는 없는 반면 5$^{\circ}C$에 저장한 김치의 경우 stevioside와 sorbitol이 첨가된 김치는 젖산균의 생육에 억제효과가 있는 것으로 나타났다 관능검사를 실시한 결과 stevioside 첨가된 김치가 sucrose 첨가구에 비하여 기호도에서는 전반적으로 우수한 것으로 나타났다.
