  • This study was carried out to find a cholesterol removal rate, flavor development, and bitter amino acid productions in Cheddar cheese treated with -cyclodextrin ($\beta$-CD): l) Control (no homogenization, no $\beta$-CD), and 2) Milk treatment (1000 psi milk homogenization, 1 % $\beta$-CD). The cholesterol removal of the cheese were 79.3%. The production of short-chain free fatty acids (FF A) increased with a ripening time in both control and milk treated cheese. The releasing quantity of short-chain FFA was higher din milk treated cheese than control at 5 and 7 mo ripening. Not much difference was found in neutral volatile compounds production between samples. In bitter-tasted amino acids, milk treatment group produced much higher than control. In sensory analysis, texture score of control Cheddar cheese significantly increased, however, that in cholesterol-reduced cheese decreased dramatically with ripening time.

  • Sulgidduk samples were prepared with substitutions of 5, 10, 15, and 20% Queso blanco cheese powder (QBCP) to rice flour basic formulation, along with a control, were then compared in terms of quality characteristics including moisture content, external surface appearance, color, textural characteristics, and sensory analysis, in order to determine the optimal ratio of formulation. Moisture contents were not significantly different among the Sulgidduk samples. For external surface appearance, as QBCP content increased, darkness and yellowness increased. With regard to color, lightness decreased with increasing QBCP content, while redness and yellowness increased. In terms of textural characteristics, hardness, gumminess, and springiness increased as QBCP content increased. The control group had significantly higher fracturability than the QBCP samples. Adhesiveness was highest at the 5% QBCP substitution level, while lowest at the 20% level. Cohesiveness was minimal the 10% QBCP sample, not significantly different among the QBCP samples. Chewiness and resilience were not significantly different among the QBCP samples. In sensory evaluation, color, flavor, and overall acceptability decreased, while softness not significantly different among the QBCP samples. Cheese flavor, saltness, milk fat taste, moistness and off-flavor increased with increasing QBCP content.

  • 본 연구에서는 가교화 ${\beta}-CD$로 크림치즈의 콜레스테롤을 효과적으로 제거하는 실험을 수행 하였으며, 크림치즈의 이화학적 변화와 관능적 특성을 살펴보았다. 크림치즈를 만들기 위한 유지방 함량 36%의 크림을 가교화 ${\beta}-CD$로 처리 시 콜레스테롤 제거 최적 조건은 가교화 ${\beta}-CD$ 10%를 첨가해 교반온도 $20^{\circ}C$, 교반시간 30분, 교반속도 800rpm으로 실험한 결과 콜레스테롤 제거율이 평균 82.0%로 나타났다. 가교화 ${\beta}-CD$처리 크림치즈는 short-chain fatty acid의 경우 저장 기간이 지남에 따라 control과 powder ${\beta}-CD$ 처리한 크림치즈에 비해 저급 지방산 생성에 변화가 거의 없고, 쓴맛을 내는 아미노산의 경우 저장 기간 동안 control과 powder ${\beta}-CD$처리 크림치즈에 비해 생산량이 현저하게 적었다. 또한 가교화 ${\beta}-CD$처리 크림치즈의 조직검사에서 다른 항목에서보다 저장 기간 동안 응집성이 변함이 없으며 그 수치가 높게 평가되었다. 관능검사 결과, 가교화 ${\beta}-CD$처리 크림치즈는 저장 기간 동안 쓴맛의 증가가 거의 없었고 전체적인 기호도 또한 높았다. 위 실험 결과에 따르면, 가교화 ${\beta}-CD$ 사용결과 cholesterol 제거율이 높으며, 제품에 적용시 재활용이 가능하고 품질이 향상되므로 이를 유가공 산업에 활용이 가능할 것으로 기대된다.

  • We explored the quality characteristics of Sulgidduk prepared using different amounts of cheese powder (0%, 6%, 12%, 18%, 24%; all w/w); physico-chemical properties were determined. Proximate composition analysis showed that the moisture content of Sulgidduk decreased with a rise in the level of added cheese powder. Lightness and yellowness values were lowest in control Sulgidduk and highest in Sulgidduk with 24% added cheese powder. Texture profile analysis showed that all of hardness, cohesiveness, springiness, and brittleness increased with a rise in cheese powder level. Scanning election microscopy indicated that the number of air cells fell as the ratio of cheese powder to rice powder increased. Sensory evaluation tests indicated that color, cheese smell, and greasiness rose as the cheese powder level increased, whereas softness and moistness fell. Consumer acceptance testing showed no significant difference in overall acceptability scores among samples. In conclusion, we suggest that cheese powder may be incorporated into Sulgidduk without affecting sensory qualities.

  • As a way of improving the texture and flavor of soybean cheese, whey-say cheeses were made by coprecipitation of various mixtures of whey, whey powder, soy milk and soy protein powder, and mixed culture of str. lactis, str. cremoris and rennet were added, then the cheeses were cured at $15^{\circ}C$ for up to 10 weeks. Physicochemical characteristics of the cheese were investigated by analyzing pH, titratable acidity(TA), water soluble nitrogen, 10% TCA soluble nitrogen, amino acid composition, beany flavor, color and hardness. The pH of whey-soy cheeses during ripening changed from 5.3 to 4.2 after 5 or 6 weeks and maintained that value while that of soybean cheese maintained a higher pH value. TA of whey-soy milk cheeses was gradually increased to the value of 0.4-0.45 after 8 weeks, but that of soybean cheese reached only 0.2 after the same period. Water soluble and 10% TCA soluble-nitrogen increased steadily during ripening. Hardness of the whey-soy milk cheeses reached maximum after three weeks of ripening and greatest at those made from 3 : 1 mixture of whey and soy milk and that from soymilk. Color of the whey-soy milk chesses was lighter than that of soybean cheese. The bean flavor of soybean cheese was strong and persistent for the whole ripening period. Acid flavor was dominant in the whey-so milk cheese and masked the beany flavor partially.

  • The objective of this study was to analyze the flavor pattern of different varieties of cheeses. Four of the each following cheese varieties such as shred type pizza cheese, Cheddar cheese, Mozzarella block cheese, and white mold-ripened cheeses, stored at $4^{\circ}C$ during 2 wks were examined before and after cooking at $70^{\circ}C$ and $160^{\circ}C$. Flavor patterns of these cheeses were analyzed using an electronic nose system based on mass spectrometer. All data were treated by multivariate data processing based on discriminant function analysis (DFA). The results showed the discriminant model by DFA method. Data revealed that flavor patterns of pizza cheeses were well separated as storage prolonged and obviously discriminated as the higher the cooking temperature. The result of pattern recognition analysis based on discriminant function analysis showed that new brand of pizza cheese produced by Imsil Cheese Cooperative was located at middle between the flavors of the imported brands of pizza cheese and those of domestic brand of pizza cheeses. Imsil cheese has a unique flavor pattern among other variety of cheeses. Application of pattern recognition analysis by electronic nose might be useful and advanced technology for characterizing in flavor pattern of cheese products from different origins and different categories of cheeses.

  • All 209 PCB congeners were analyzed in cheese produced in Korea and Canada. 5 Korean and 10 Canadian cheeses were purchased in supermarket in their native countries. 93 PCB congeners were found in Korean cheese; 83 congeners were detected in Canadian cheese. Total PCB concentrations were 299.81 and 200.96 pg/g w.w. in Korean and Canadian cheeses respectively; PCB concentration was 1.5 times higher in Korean than Canadian cheese. Korean TEQ concentration (0.0067 pg-TEQ/g w.w.) in cheese was similar to in Canadian cheese (0.0064 pg-TEQ/g w.w.). These PCB concentrations range was low level compared with that of other cheeses globally. The correlation coefficient $(R^2)$ of regression was high (0.752) between each PCB congener concentration in both Korean and Canadian cheese.

  • The replacement effects of cheese far salted and fermented fish on growth of lactic acid bacteria, fermentation velocity and sensory characteristics of Kimchi were investigated. In both control and cheese Kimchi, the total viable cell count of lactic acid bacteria was increased rapidly during the initial 2 days of fermentation. From 3 days after preparation, Kimchi added with cheese showed higher number of lactic acid bacteria than control Kimchi. The pH of Kimchi decreased rapidly after a small increase at the first day of fermentation, reaching 4.18-4.33 at the third day of fermentation, and the pH was slightly lower in Kimchi added with cheese than in control. Proximate analysis of Kimchi added with cheese was slightly higher in moisture and lower in crude protein and fat than control Kimchi. Sensory evaluation of the Kimchi fermented for 3 days showed that the Kimchi added with 3 or 5% of cheese had higher scores of appearance, flavor and overall taste than the control Kimchi.
