Abstract

The aim of this study was to investigate the effects of guar gum on the rheological behaviors, sensory attributes, and consumer acceptability of soft tofu stew sauce. Five different soft tofu stew sauces were commercially manufactured with various levels of guar gum (0.0, 0.1, 0.2, 0.4, and 0.5%). Twelve sensory attributes of the stew sauces were identified by nine trained descriptive panelists, whereas hedonic levels of the stew sauces were assessed by a group of 51 consumers. Steady flow of the stew sauces were measured by a rheometer. Significant differences were observed in terms of sensory saltiness and viscosity among the products. For the consumer test, 0.1% guar gum-added product was most liked by consumers. Partial least square regression showed sensory shellfish, green onion, and shrimp flavors to be key factors affecting overall acceptability for the stew sauces. For rheological behaviors, 0.0, 0.1, and 0.2% guar gum-added products showed newtonian behaviors ($R^2$=0.99 by power law model), whereas 0.4 and 0.5% products followed pseudoplastic behaviors ($R^2$=0.99 by power law model). Based on the established equivalence table using rheological and consumer data, smaller than 0.0114 ($Pa{\cdot}s$) of the apparent viscosity should be necessary to guarantee 'slightly like' category in a consumer hedonic test. It seems that addition of guar gum not only influenced rheological properties but overall acceptability for the stew sauces.

본 연구는 순두부찌개 소스의 품질 특성에 영향을 주는 guar gum의 농도를 다르게 첨가하여 제조한 순두부찌개 소스의 품질 특성의 변화를 알아보고 그 특성들이 소비자 기호도에 어떤 영향을 끼치는지 알아보았다. 그 결과 짠맛은 guar gum 농도의 증가에 따라 유의적으로 감소하는 결과를 보였고 소비자 기호도에 영향을 주는 인자로는 조개맛, 새우맛, 파향이 나타났으며, 모두 부정적인 영향을 주는 인자로 나타났다. 순두부찌개 소스의 유동 특성은 guar gum 농도가 증가할수록 pseudoplastic 한 성질이 증가되는 결과가 나타났으며 guar gum 농도의 증가와 소비자 기호도를 토대로 소비자 기호도 예측 모델을 개발하였다. 그 결과 guar gum의 농도가 증가할수록 소비자 기호도가 감소하였고 소비자 기호도를 보통 이상으로 유지하기 위해서는 겉보기 점도를 0.0114($Pa{\cdot}s$) 이하로 유지해야 할 것으로 사료된다. 따라서 본 연구 결과는 guar gum 함량에 따른 소스 제품의 품질 평가의 기초 연구로 소스 제품의 품질 최적화에 활용될 수 있을 것으로 판단된다.
