Heretofore described wheat gluten protein is based on alcohol soluble protein and glutelin, and protein content is 75%~90%；It is micro-
The wheat gluten protein Powder Particle Size of micronization processes is the mesh of 800 mesh~1500.The kaolin addition is 0.30~0.80 mass
Number, the mass fraction of precipitated calcium carbonate addition 0.35~0.75.
Beneficial effects of the present invention are as follows：
The present invention obtains the wheat gluten protein fine powder of characteristic particle size scope by wheat gluten protein miniaturization handling process
Body, hence it is evident that improve its surface hydrophobic in aqueous isopropanol, the viscosity of wheat gluten protein-aqueous isopropanol is also with small
The reduction of wheat mucedin powder granularity and dramatically increase, hence it is evident that improve wheat gluten protein building coating water resistance and wall
The uniformity of appearance of film.In addition, the present invention develops coating for wall surface product, realizes grain using vegetable protein as raw material
The increment for eating processed side product is utilized, while the consumption of the materials such as non-renewable resources oil is decreased, to improving wheat flour
Muscle Protein processing is respectively provided with weight using the utilization of quality, the commodity value of lifting wheat gluten protein, saving non-renewable resources
Want meaning.
