The invention discloses a composite
protein powder capable of improving
immunity and a preparation method thereof. Using
soybean protein isolate, concentrated
whey protein and phospholipids as main raw materials, stevia is processed into
stevia extract at low temperature, which can retain Active ingredients and bioactive ingredients of stevia, high extraction rate, pure
flavor, natural color, no licorice taste, scientifically compounded with main ingredients, and added
antifreeze polypeptide,
dietary fiber powder, bee chrysalis enzymatic hydrolyzate,
wheat germ Powder, to prepare a compound
protein powder with suitable taste, good
solubility, comprehensive
nutrition, strong
biological activity, suitable for a wide range of people, and capable of improving
immunity. The preparation method adopts non-thermal
processing technology, which has high work efficiency, low
energy consumption, environmental friendliness, no
pollution, reduces the introduction of food additives and chemical additives, effectively improves
food safety, improves product quality and reduces production costs , achieved the goal of low-carbon production, and can be scaled and industrialized.
