Abstract

The quality characteristics and antioxidant activity of three kinds of tofu made from lipoxygenase (LOX)-free genotypes soybeans were compared to the Taekwang (LOX-present) tofu as the control. The mineral contents of Jinyang tofu were significantly higher than those of the control. The hardness and gumminess of tofu made from LOX-free genotypes were significantly higher than those of the control. Gaechuck#2 tofu showed higher sensory evaluation results than the other kinds of tofu in terms of taste, flavor and overall acceptability. The total isoflavone contents were higher in the LOX-free genotypes than in the control. The total phenol content was similar for the Gaechuck#1, #2 and Taekwang tofu. The flavonoid content was higher in Gaechuck#1 and #2 tofu than in the control. The antioxidant activities were the highest in Gaechuck#1 tofu, followed by the Gaechuck#2. During the 15-day storage at $4^{\circ}C$, the turbidity of the immersing water tended to increase, but Gaechuck#1 and #2 tofu were significantly lower than in the control after 15-day storage. Therefore it is suggested that Gaechuck#2 tofu could be the suitable genotype for tofu products because it is the most effective in terms of overall acceptability, antioxidant activity, and storage stability.

LOX 결여 콩(개척#1, 개척#2 및 진양)과 일반콩(태광)으로 만든 두부의 이화학적 특성 및 항산화 활성을 비교하였다. 두부의 무기물 함량은 대조구에 비해 진양 두부에서 훨씬 높은 함량이었다. 경도 및 검성은 대조구에 비해 LOX 결여 콩 두부에서 유의적으로 높았다. 두부의 맛, 풍미를 포함한 전체적인 기호도는 개척#2 두부가 다소 높게 평가되었다. 두부의 이소플라본 함량은 대조구에 비해 LOX 결여 콩 두부에서 높았다. 두부의 총 페놀 함량은 대조구와 개척#1 및 개척#2 두부에서 비슷한 수준이었으며, 플라보노이드 함량은 대조구에 비해 개척#1 두부는 2.6배, 개척#2 두부는 1.4배 높았다. 두부의 항산화 활성은 개척#1 두부에서 가장 높았으며, 다음으로 개척#2 두부였다. $4^{\circ}C$에서 15일 저장하는 동안 두부 침지액의 탁도는 점차 증가하였는데, 저장 15일 경과 후 개척#1 및 #2 두부는 태광 두부에 비해 유의적으로 낮았다. LOX가 결여된 개척#1 및 #2 두부는 이소플라본 및 총 페놀 함량이 태광 두부에 비해 높아 항산화 활성 및 저장 안정성에 효과적이었으며, 특히 개척#2 두부는 전체적인 기호도가 높아 LOX 결여 콩 품종이 두부 가공에 적합할 것으로 판단된다.
