The present application relates to the technical field of
protein powder processing, and discloses a formula for solving instant
protein powder. The formula comprises the following components in parts by weight: 70-100 parts of
protein base, 2-10 parts of
trehalose, 0.5-3 parts of
triethyl citrate, and 0.1-1 parts of
silicon dioxide. The preparation method adopts a technical
route combining controllable enzymolysis, heat preservation and standing, and three-stage
temperature control spray drying: first, controllable enzymolysis is used to make the degree of
hydrolysis of the protein base reach 7-10%, generating enzymolysis
peptide segments; then, after cooling,
trehalose and
triethyl citrate are added, and nano particles with a particle size of 50-110 nm are formed by heat preservation and standing; finally, three-stage
temperature control spray drying is used to obtain instant protein
powder particles. The present application forms a protective layer by generating
small particles on the surface and inside of the
protein particles, so that the protein powder can be quickly dispersed and dissolved in different media such as water, milk, and
fruit juice, and can meet the requirements of multi-medium instant
dissolution and stable suspension.
