Abstract

The invention belongs to the field of food, and discloses flammulina velutipes polysaccharide-soybean protein gel suitable for 3D printing, which is prepared by the following steps: taking flammulina velutipes polysaccharide and soybean protein as raw materials, dissolving the flammulina velutipes polysaccharide in water to prepare a flammulina velutipes polysaccharide aqueous solution, uniformly mixing the soybean protein with the flammulina velutipes polysaccharide aqueous solution to obtain polysaccharide-protein condensation gel, and performing vacuum drying on the polysaccharide-protein condensation gel to obtain the flammulina velutipes polysaccharide-soybean protein gel. And heating the polysaccharide-protein condensate gel, and cooling to room temperature to obtain the polysaccharide-protein gel. The mass of the flammulina velutipes polysaccharide accounts for 1-10% of the total mass of the soybean protein and the flammulina velutipes The invention further discloses a preparation method of the flammulina velutipes polysaccharide-soybean protein gel suitable for 3D printing. The flammulina velutipes polysaccharide-soybean protein gel is suitable for being prepared into 3D printing products, the printing products are uniform in texture, the printing accuracy reaches 98% or above, the printing stability reaches 99.7% or above, and the purposes of high-protein food processing, food structure customization and food nutrition functionalization are achieved.

Description

technical field

[0001] The invention belongs to the field of food, in particular to the technical field of novel food processing, and relates to a enoki mushroom polysaccharide-soybean protein gel suitable for 3D printing and a preparation method thereof. Background technique

[0002] 3D printing technology is a kind of additive manufacturing technology, which has the advantages of high precision, high reproducibility, and customization. 3D printing can construct foods with different shapes, sizes, and filling rates through models to enrich the taste, improve palatability, and enhance the fun of food. Through the adjustment of materials, foods with different nutrition and tastes can be precisely customized to meet the needs of different groups of people. However, the current restrictions on the application of 3D printing technology to food are mainly due to the limited food materials that can realize 3D printing, which needs to be expanded urgently.
