Research of additives on texture property and microstructure of Yuba

The effect of additives ( such as glycerol, trehalose, sucrose ester, and monostearin) and different additives combination on texture characteristics, color, microstructure properties of Yuba were studied.The results showed that glycerol, trehalose, sucrose ester, and monostearin could improve the texture property of Yuba. Adding the compound additives could improve the quality of Yuba, and the combination of glycerol, trehalose, and sweet ester ( 2%, 0.5%, 0.5%) had the best effect on the comprehensive quality of Yuba.The microstructure of Yuba was observed by transmission electron microscopy ( TEM) and infrared spectroscopy ( IR) , found that the intermolecular network gaps of the macromolecules in the Yuba was reduced by the interpenetration of the small molecules of the additive, thus improving its mechanical properties.
