The invention provides a mixed
protein base material and application thereof, and the mixed
protein base material comprises the following components in percentage by
mass: 25%-80% of
whey protein, 15%-70% of
collagen peptide, 2%-4% of moderately hydrolyzed
whey protein, 1%-2% of highly hydrolyzed
whey protein and 2%-4% of whey
protein rich in milk
phospholipid membrane. According to the mixed protein base material provided by the invention, an oil-water interface of an
emulsion is jointly stabilized through proteins with different molecular weights and compositions, the
emulsion and microcapsules can be effectively stabilized, and fat-soluble functional factors are further delivered by utilizing the obtained
emulsion and microcapsules, so that the stability of the fat-soluble functional factors can be improved; and the
bioavailability can be improved.
