This study investigates the physicochemical and sensory properties of the soy-based patties using κ-carrageenan (CG) and methyl-cellulose (MC) as binders. Soy-based patties were prepared using 0%-2% of κ-carrageenan and methyl-cellulose in proportion, and the quality change of soy-based patties was measured by storing them at 4oC for 4 weeks. During the storage periods, the water holding capacity of ‘MC 1.5%+CG 0.5%’ showed high values.
As the MC content increased, the weight loss and cooking loss tended to decrease, and both values increased significantly during the storage period. As the MC content increased, the lightness and redness tended to decreased.
The hardness and chewiness of soy-based patties tended to increase as the MC content increased. During the storage period, the total aerobic bacteria and the coliforms tended to increase. The VBN content was showed 14.6-17.5 mg%/100g in first week, since then, the VBN content has continued to increase. As a result of sensory evaluation, the springiness, taste and overall acceptability of soy-based patties with ‘MC 1.5%+CG 0.5%’ and ‘MC 2.0%’ showed the highest value.
