Abstract:

The mechanisms of interaction between acetylated distarch adipate and soymilk on yuba membrane were
investigated using differential scanning calorimeter, fluorospectro photometer and scanning electron microscope. The results
showed that during dyestripping, the acetylated distarch adipate was inlayed in the interspaces of the network structure
when the protein was denaturized, resulting in more compacted protein film and accordingly increased yuba yield with
improved mechanical capacity. Therefore, the addition of acetylated distarch adipate can enhance the hydrogen bond, surface
hydrophobicity and emulsifying capacity of soybean proteins.

Key words: acetylated distarch adipate, yuba, mechanism, fluorospectro photometer, scanning electron microscope
