| Abstract: | Different concentrations of coating with soy protein isolate (SPI) and chitosan (CH),separately or combined together were prepared to explore the effect of coating treatment on the tofu qualities.The quality properties including total plate count,sensory properties,texture,color were evaluated and scanning electron microscope (SEM) were used to observe the morphology of the surface and cross section of coated tofu.The study concluded that the tofu treated with the composite membrane solution (2.0%CH+0.5%SPI) had the lowest value with total plate count and the highest sensory evaluation score.In addition,by SEM observation it was also showed that the surface of the tofu treated with the composite membrane solution at the same condition displayed a denser and more uniform appearance with smooth and clear coating. |
