This study was done to provide the basic information of bread made with curry powder. The amounts of curry powder used were 0 to 3% based on the wheat flour weight. The quality of bread was investigated by evaluation of the specific loaf volume, water absorption capacity, color, sensory quality and texture. The weight of bread decreased with the increase of curry power contents, but there were no significant differences among 0.5, 1 and 2% added curry powder bread. The volume and specific loaf volume also decreased with the increase of curry power contents, but those decreases were not significant between 1% one and 2% one. The water absorption capacities were not affected by the addition of curry powder. The lightness and redness decreased with an increase of curry powder content in the bread, while yellowness increased significantly(p<0.01). The result of the sensory evaluation showed that total acceptabilities of appearance, aroma, texture and taste in the bread with 0.5% and 1% curry powder were significantly higher than the control group and the other groups. Overall quality was negatively affected by the yellowness, odor, hot and bite taste of added curry powder. The factors affecting on the overall quality of the bread with added curry powder were in order of taste quality > curry powder odor > texture quality > aroma quality > springiness > wheat flour odor.

Texture is a major challenge in addressing the need to find sustainable meat alternatives, as consumers desire alternative meat to have a sensory profile like meat. In this study, the fabrication of imitated muscle fiber (IMF) is performed by introducing different kinds of protein sources, with an effective bottom-up technique- wet spinning. Herein, the protein sources (pea protein isolate, wheat protein, and myofibrillar paste) were combined with sodium alginate to stimulate the bonding with the coagulation solution for fabrication. It has been found that the fabrication of IMF is possible using all the protein sources, however, due to the difference in protein structure, a significant difference was observed in quality characteristics compared to conventional meat. Additionally, combination of wheat protein and pea protein isolate has given similar values as conventional meat in terms of some of the texture profiles and Warner-Bratzler shear force. In general, the optimization of protein sources for wet spinning can provides a novel way for the production of edible fiber of alternative meat.

본 연구는 증편 제조기법을 이용하여 피자 crust 제조를 시도한 논문으로서 이를 위한 표준 recipe의 제시와 발효시간, 점도의 변화 및 완성된 증편피자의 질감특성과 수응도를 기계적 검사와 관능검사를 통해 평가하였다. 이를 위해서 기존의 증편 제조시 사용하는 탁주와 콩물을 이스트와 날콩가루로 대체하였으며 날콩가루 첨가 수준을 달리하여 그 효과를 연구하였다. 증편 제조기법을 이용하여 증편 crust를 제조한 결과 질감과 형태가 피자 crust로 사용하기에 적당한 것으로 나타났으며 이를 위한 표준 recipe를 제시하였다. 증편 제조시 날콩가루를 첨가한 결과 부피가 증가하는 속도가 빨라져서 1차, 2차 발효에 걸리는 시간이 단축되었다. 특히 5% 날콩가루 첨가군의 경우 대조군에 비해 발효시간이 유의적으로 짧아졌다. 1차, 2차 발효 후의 증편 반죽의 점도는 날콩가루 첨가에 따라 모두 유의적으로 증가하였다. 완성된 증편 crust의 질감을 기계적으로 측정한 결과 날콩가루 첨가군이 대조군에 비해 경도, 검성, 씹힘성이 낮은 것으로 나타났으며 씹힘성은 날콩가루 5% 첨가군이 대조군에 비해 유의적으로 낮았다. 이와 같이 제조 직후에는 날콩가루 첨가가 완성된 증편 crust의 질감에 큰 차이를 나타내지 않았으나 저장시에는 노화를 지연시키는 효과가 있을 것으로 기대된다. 관능검사 결과 증편 피자의 질감 특성은 기계적 검사결과와 유사하게 경도, 응집성, 부착성, 촉촉한 정도가 날콩가루 첨가에 의해 낮아지는 것으로 나타났다. 특히 5% 첨가군의 경우 대조군에 비해 유의적으로 질감 특성이 낮게 나왔다. 3% 날콩가루 첨가군의 질감 특성은 대조군에 비해 유의적인 차이가 없었으며 외관, 부드러운 정도, 전체적인 수응도에서는 오히려 좋은 점수를 받았다. 이상의 결과로 증편 제조기법을 이용하여 피자 crust 성형이 가능하며 날콩가루를 3% 정도 첨가하였을 때 발효시간이 단축되고 질감과 수응도는 대조군과 큰 차이가 없이 우수한 것으로 나타났으며 저장시 노화지연 효과를 기대할 수 있었다. 본 연구는 전통적인 증편 제조기법을 현대인이 선호하는 편의식인 피자와 접목시킴으로서 한국형 건강 편의식 개발을 위한 증편 피자 개발을 시도하였다.

In sourdough fermentation, lactic acid bacteria perform important roles in the production of volatile and antimicrobial compounds, and exerting health-promoting effects. In this study, we report the probiotic properties and baking characteristics of Lactobacillus plantarum SPC-SNU 72-2 isolated from kimchi. This strain is safe to use in food fermentation as it does not carry genes for biogenic amine production (i.e., hdc, tdc, and ldc) and shows no β-hemolytic activity against red blood cells. The strain is also stable under simulated human gastrointestinal conditions, showing tolerance to gastric acid and bile salt, and adheres well to colonic epithelial cells. Additionally, this strain prevents pathogen growth and activates mouse peritoneal macrophages by inducing cytokines such as tumor necrosis factor-α, interleukin (IL)-6, and IL-12. Furthermore, the strain possesses good baking properties, providing rich aroma during dough fermentation and contributing to the enhancement of bread texture. Taken together, L. plantarum SPC-SNU 72-2 has the properties of a good starter strain based on the observation that it improves bread flavor and texture while also providing probiotic effects comparable with commercial strains.

In this study, we assessed the physicochemical and sensory characteristics of cookies containing various concentrations (0, 3, 5, 7 and 9%) of leek powder. The L values of cookies containing leek powder were significantly lower than those of the controls. The spread ratio decreased proportionally with the quantity of leek powder added to the cookie recipe. The loss rate and leavening rate of samples to which 3% and 5% leek powder was added evidenced a higher value than the samples to which 7% and 9% leek powder was added. The L value of brightness was significantly reduced when leek powder was added to the cookie recipe. The a and b values were also significantly reduced with the addition of leek powder. Hardness evidenced significantly high levels in the samples to which 3% and 5% leek powder was added. The results of our sensory evaluation evidenced significantly better appearance, flavor, color, texture and overall acceptability as compared to the 3% and 5% added samples. The observed quality characteristics of the 3% leek powder added samples and 5% leek powder added samples indicated the possibility that leek cookies might be developed.

The aim of this study was to evaluate the physico-chemical, sensory, and microbiological properties of ready-to-eat Korean traditional seasoned beef ribs ("galbi-jjim") prepared by sous-vide/cookchill technology during storage at three different temperatures (4, 10, and $20^{\circ}C$). Beef short ribs marinated in soy sauce for 24 h at $3^{\circ}C$ were packed with vegetables under vacuum. Vacuum-packed beef ribs mixed with vegetables were heated at $90^{\circ}C$ for 90 min in a water bath, and then immediately chilled below $3^{\circ}C$ within 120 min in an ice slurry. Physicochemical (pH, water activity, TBARS, $L^*a^*b^*$ color, and texture profile), sensory (appearance, odor, flavor, texture, and acceptance) and microbiological (Coliform, Escherichia coli, food-borne pathogenic bacteria) properties of the samples were determined during storage at different temperatures. Results showed that pH, $a_w$, and sensory evaluation of products were not affected in any consistent way as a function of either storage duration or temperature. Coliform, E. coli and food-borne pathogens were not detected during storage at any temperature. However, TBARS significantly increased during storage period (p<0.05). Based on TBARS values, SV/CC "galbi-jjim" can be stored for 15 d, 12 d and 1 d at 4, 10 and $20^{\circ}C$, respectively.

본 논문에서는 식물성 육류 유사식품에 대한 개념과 소비자 인식, 발달과정, 그리고 시장전망에 대해 조사하였다. 전 세계적으로 육류 소비량 및 요구량이 증가함에 따라 지구온난화와 토지부족과 같은 환경적인 문제가 발생하고 있다. 또한, 소비자들의 종교적 또는 개인적 신념에 따른 식생활에 대응해야 하는 상황에서, 기존 육류를 대체할 수 있는 육류 유사식품의 필요성은 꾸준히 증가하고 있다. 육류 유사식품의 원료 중 대표적으로 식물성 단백질원이 있으며 대두단백, 콩, 밀, 목화씨 등이 이용된다, 동양권에서는 전통적으로 섭취되어온 두부, 세이탄, 템페 등이 식물성 육류 유사식품에 해당한다. 서양에서는 1930년대부터 식물성 육류 유사식품을 본격적으로 생산하기 시작하였으며, 최근 다양한 제품들을 출시하고 있다. 육류 유사식품의 경우 식물성 원료의 압출성형 공정에 대한 연구와 제품의 관능적 특성을 향상시키기 위한 연구가 지속적으로 이루어지고 있다. 전통적인 식육생산 시스템의 한계로 인해 식육 유사식품 시장은 지속적으로 성장할 것이라 예측된다. 특히 최근 출시 중인 식물성 육류 유사식품의 경우, 관능적으로 우수하여 소비자들의 관심이 더욱 증가할 것으로 전망한다.
