Type-controllable double-gel fat as well as preparation method and 3D printing application thereof

The invention discloses a type-controllable double-gel fat-like product as well as a preparation method and 3D printing application thereof, and belongs to the technical field of grease processing and fat-like product 3D printing. The preparation method of the type-controllable double-gel fat comprises the following steps: dissolving natural wax and a small molecule emulsifier in vegetable oil to obtain an oil gel solution; dissolving water-soluble polysaccharide in water to obtain a hydrogel solution; mixing the oil gel solution and the hydrogel solution, and homogenizing to obtain a double-gel emulsion; and then gelation is carried out, such that the double-gel fat is obtained. The type-controllable double-gel fat substitute prepared by the method has obvious beneficial effects in the aspect of food 3D printing, and different types of double-gel fat substitutes have obvious applicability difference on a printing model, so that the method has great guiding significance in 3D printing application of fat custo
