The invention relates to the field of gel, in particular to gel of polymerized
whey protein and
dendrobium officinale
polysaccharide and application of the gel in preparation of yoghourt or a gel base membrane. Comprising the following steps: (1) dissolving
whey protein and
dendrobium officinale
polysaccharide powder in deionized water, and uniformly mixing; adding an
inducer, adjusting the pH value, heating and cooling to prepare polymerized
whey protein and
dendrobium officinale
polysaccharide hydrogel; (2) dissolving goat milk
powder with deionized water, adding
sugar, sterilizing, cooling, adding polymerized whey
protein and
dendrobium officinale polysaccharide gel, inoculating a
leavening agent, and fermenting to obtain yoghourt; (3) adding
glycerol into the polymerized whey
protein and
dendrobium officinale polysaccharide gel, and stirring to obtain a film forming solution; and uniformly spreading the film forming liquid, and
drying to obtain the gel base film. According to the invention, the texture of the goat milk yoghourt is improved, and the application of polymerized whey
protein and
dendrobium officinale polysaccharide in dairy products is widened; the quality of the fruits is improved, and the application of the protein and the dendrobium officinale polysaccharide gel base membrane is widened.
