Lactone bean curd powder and method for preparing lactone bean curd

The invention relates to lactone bean curd powder and a method for preparing lactone bean curd, and belongs to the field of food processing. The lactone bean curd powder is prepared from albumen powder and glucolactone, and the albumen powder is prepared from soyabean protein, peanut protein and walnut protein by the mass ratio of 10:8-10:5-8. The lactone bean curd contains glucolactone, so that it is unnecessary to add glucolactone in the preparing process, and the step of curdling is omitted; the lactone bean curd can be obtained just through dissolving, heating and cooling, and the preparing technology of the lactone bean curd is greatly simplified. As the step of curdling is omitted, the situation that as a curdling technology is difficult to control, the bean curd quality and structure are instable is avoided. By compounding the three materials, glucolactone can achieve the uniform and stable curdling effect (the lactone bean curd is uniform in texture and smooth in mouthfeel) even if glucolactone exists before a protein dissolving solution is heated.
