The effect of garlic addition on quality and shelf-life of soybean curd was investigated. The yield of garlic soybean curd slightly decreased in proportion to amount of garlic added. In the case of texture, hardness of the garlic soybean curd increased when $5{\sim}10%$ garlic was added, whereas hardness, adhesiveness, cohesiveness, springiness and chewiness significantly decreased in the case of 20% garlic added. Microbial counts of soybean curd stored in sterilized distilled water as tofu-immersion solution increased, whereas pH decreased during storage at $15^{\sim}C$. During all storage periods, microbial counts of the soybean curds containing garlic were always lower than that of the ordinary soybean curd. These results imply that garlic is a useful additive in suppressing the proliferation of aerobic microorganism and has a potential use in extending the shelf-life of soybean curd. According to yield, textural properties and shelf-life data, the suitable concentration of garlic was around $5{\sim}10%$.
