This study addresses the development of a soy hamburger patty containing enzyme-treated textured soy protein (TSP) as a meat analogue. In order to reduce the beany flavor and enhance the texture, TSP was treated with 0.3% Flavourzyme for 5, 10, 20, or 30 min. The degree of hydrolysis and the water holding capacity of the TSP increased with increasing hydrolysis time. The oil binding capacity of the TSP also increased with increasing hydrolysis time, approaching the maximal value, 175.82%, at 30 min, whereas that of pork scored with the lowest value of 128.67%. The volume of pork was reduced to 81.5% as the result of heat treatment, whereas that of the TSP increased to 140.57%. The values of 'L', 'b', and '${\Delta}E$' differed significantly (p<0.001) with heat treatment, but the 'a' values did not differ significantly. With regard to texture, the hardness values were highest in the pork hamburger patty (PHP), and were lowest in the soy hamburger patty (SHP) containing untreated TSP. The hardness of the SHP containing TSP treated for 20 min did not differ significantly from that of the PHP. The cohesiveness and gumminess of the SHP treated for 20 min were highest, whereas those treated for 10 min were the lowest. The gumminess of the SHP treated for 20 min did not differ significantly from that of pork. The chewiness of the PHP was the highest, whereas that of the SHP treated for 5 min was the lowest. In our sensory evaluation, PHP evidenced the highest scores, followed by the SHP treated for 30 min, as color, texture, beany flavor, and overall quality all improved as the consequence of increasing enzyme treatment duration. In conclusion, it is believed that SHP has great potential as a substitute for meat, in that the flavor, texture, and beany flavor of SHP did not differ significantly from those of PHP.

동방유량(東邦油糧)에서 저변성탈지대두박(低變性脫脂大豆粕)을 공급받아 Soy Protein Isolates(SPI)를 제조(製造)하여 이의 식품학적(食品學的) 특성(特性)을 연구(硏究)한바 있다(Korean J. Food Sci., 9, 123(1977)). 이 SPI의 실제응용성(實際應用性)을 검토(檢討)하고자 12% SPI액(液)을 가열(加熱) gel화(化)시켜 풍건 마쇄한 SPI를 beef patties의 증량제(增量劑)로 사용하였을 때, SPI gel로 30% meat를 대체하여도 관능검사(官能檢査) 결과(結果) 유의성(有意性) 있는 차이(差異)를 나타내지 않았다. 또한 cooking loss도 13.5%(대조구(對照區))에서 2%로 현저히 줄었다. SPI를 milk-Solid-Not-fat(MSNF)와 대체하여 제조한 아이스크림은 관능검사결과(官能檢査結果) texture는 대조구(對照區)과 차이(差異)가 없었으나 향미면(香味面)에서 콩비린내 때문에 전체적(全體的) 품질(品質)이 크게 떨어졌다. 이것은 아이스크림이 향미(香味)가 전체품질(全體品質)에 큰영향을 갖는 그 자체의 특성때문인 것으로 간주된다. 탈지대두박(脫脂大豆粕)에서 추출(抽出)한 분리대두단백(分離大豆蛋白)은 콩비린내 문제만 해결(解決)되면 우수한 식품학적(食品學的) 특성(特性)때문에 동물성(動物性) 단백질(蛋白質)과 대체하여 식품제조시(食品製造時) 첨가제(添加劑)로서 사용이 가능(可能)함을 알았다.

The objective of this study was to develop sensory lexicons that can be utilized for various types of tofu such as pressed, unpressed, and tofu made from germinated soybeans, using generic descriptive analysis. In the first phase of the experiment, trained descriptive panelists developed and defined the appearance, aroma, flavor, and texture attributes that are commonly present in tofu. Then, the sensory characteristics of seven types of tofu were analyzed using the sensory lexicons established in the initial stage of the experiment. Four appearance, 6 odor/aroma, 6 flavor/taste, 7 texture, and 4 aftertaste attributes were identified, and reference standards were established for most of the terms in order to facilitate the understanding of the attribute definitions. The intensities of the sensory attributes were measured on a 15-point scale. Statistical analyses, including analysis of variance and principal component analysis, were used for the data. The seven tofu samples showed significant differences in the intensities of 22 attributes. The unpressed tofu samples were generally rated as being high in moistness, easy to cut, silky, and easy to swallow. The pressed tofu, on the other hand, was salty, astringent, beany, hard, and rough in texture. The tofu made with germinated soybeans was characterized as having a strong cooked bean flavor, salty and astringent aftertaste, and hard texture. Overall, the attributes of moistness, easy to swallow, and silkiness showed strong positive correlations; hardness and sticks to teeth were also positively correlated to each other.

The development of soy cutlets containing textured soy protein (TSP) as a meat analog was studied. In order to decrease the beany flavor and to increase the texture, TSP was treated with 0.3% Flavourzyme or 0.1% Protamex for 10 or 20 min, respectively. The degree of hydrolysis for TSP treated with Protamex was higher than that treated with Flavourzyme. Hydrolysis was observed to increase as the reaction time was increased for both Flavourzyme and Protamex. The water holding capacity of TSP treated with Protamex for 10 min was the highest, and that treated with Flavourzyme for 20 min was similar to that of Protamex treatment for 20 min. The oil binding capacity of TSP treated with Protamex for 20 min was the highest. The hardness of the soy cutlets using TSP treated with Flavourzyme for 10 min was higher than that treated for 20 min, while that of Protamex treated for 20 min was higher than that treated for 10 min. The cohesiveness of the soy cutlets using TSP treated with Flavourzyme or Protamex for 10 min was higher than those treated for 20 min. The chewiness of the soy cutlets treated with Flavourzyme for 10 min was higher than for those treated for 20 min, while those treated with Protamex for 20 min was higher than those treated for 10 min. The springiness of TSP treated with Flavourzyme for 20 min was higher than those treated for 10 min, and higher than those treated with Protamex for 10 or 20 min. For sensory evaluation, the beany flavor of the soy cutlets treated with Protamex for 20 min was the weakest. The flavor and chewiness of both a pork cutlet and a soy cutlet treated with Protamex for 20 min were the best. In the overall quality, soy cutlets treated with Protamex for 20 min was the most desirable. In conclusion, soy cutlets treated with 0.1% Protamex for 20 min could be a reasonable substitute of pork cutlets.

Seolleongtang, a traditional broth in Korea, is expected to become a hot global item for its unique flavor and healthiness. In this study, the correlations between sensory attributes and physicochemical characteristics were studied for the popular seolleongtang stock products through descriptive analysis, sensory evaluation and analysis of salt, soluble solid, protein, viscosity and color for the quality control. Our results indicate that color, concentration, viscosity, and freshness are important attributes in evaluating the quality of seolleongtang stock. There were significant differences between preference and sensory attributes among the stock products. Significant correlations were found between flavor and texture and overall acceptability, as well as beany odor and aroma. Preference and physicochemical aspects also correlated, and indicate that a range of salt, solubility, and viscosity are applicable as quality control factors in seollengtang stock.

Soy sauce, a basic ingredient in Asian cuisine, is made of fermented soybeans, salt, water, and barley or wheat flour. The sensory characteristics of soy sauce are not only determined through its main ingredients but also by various flavor compounds produced during the fermentation process. This study was conducted to identify the sensory attributes of five different commercial soy sauce samples that differ in Meju types (traditional Meju or modified Meju) and usage types. Thirty three sensory attributes, including appearance (1), odor (16), flavor (14), and mouthfeel (2) attributes, were generated and evaluated by eight trained panelists. The collected data were analyzed by analysis of variance and principal component analysis. There were significant differences in the intensities of all sensory attributes among the soy sauce samples. Soy sauce made with traditional Meju had high intensity of fermented fish, beany, musty odors and salt, Cheonggukjang, fermented fish flavors. Whereas two soy sauces made with modified Meju were strong in alcohol, sweet, Doenjang, roasted soybean flavors. Two soy sauces for soup made with modified Meju had medium levels of briny, sulfury, fermented odors and bitter, chemical flavors and biting mouthfeel characteristic.
