Abstract

The invention relates to hydrolyzed D90 demineralized whey powder and a preparation method thereof. The hydrolyzed D90 demineralized whey powder comprises a D90 demineralized whey solution, a protease preparation, and an acidity regulator. The preparation method comprises the steps of preparing the D90 demineralized whey solution by dissolving sweet whey powder with water, and performing desalinization treatment to remove mineral substances, allowing the D90 demineralized whey solution to enter an tank, performing circulating heating, adjusting the pH target value of the D90 demineralized whey circularly-heated material solution by adding potassium hydroxide, adding trypsin and neutral protease into the D90 demineralized whey solution, performing enzymolysis on the D90 demineralized whey solution under stirring in a circulating heating and heat preservation condition, performing circulating cooling on material liquid in which the D90 demineralized whey solution is in the end of hydrolysis to inhibit the activation of enzymes, performing sterilizing, enzyme deactivation and concentration by using an evaporator for concentration, and performing spray drying by using a spray drying tower to prepare a dried powdery product. According to the invention, the nutritive value of the demineralized whey powder is further improved, and the protein allergy influence is reduced, the protein nutrition absorption efficiency is improved, and the hydrolyzed D90 demineralized whey powder and the preparation method thereof are applied to the technical field of food nutrition.

Description

technical field [0001] The invention relates to a hydrolyzed D90 desalted whey powder in the technical field of dairy products and a preparation method thereof. Background technique [0002] Hydrolyzed protein products can be used in infant formula milk powder, health food, special dietary food and nutritional supplement food, and have broad market prospects as functional ingredients. In recent years, hydrolyzed desalted whey powder has been favored by consumers for its good taste and physiological functions. Hydrolyzed desalinated whey powder is a hydrolyzed protein dairy product raw material that uses desalted whey liquid as the main raw material, and the whey protein in it is enzymatically hydrolyzed by protease preparations. Because the hydrolyzed desalted whey powder has the characteristics of reducing allergies and easy digestion and absorption, the whey protein in the desalted whey liquid is decomposed into short peptides and amino acids through enzymatic hydrolysis....
