Example Embodiment

[0030] Example 1

[0031] A preparation method of milk protein microcapsule finishing agent, comprising the following steps:

[0032] (1) mixing the aqueous solution containing milk protein and gelatin with the aqueous solution containing gum arabic to obtain a mixed solution, and the milk protein in the mixed solution accounts for 15% by weight at this time;

[0033] (2) dilute with water at 40°C, and then add an aqueous solution containing 4% by weight of maleic anhydride and isopropylene ether copolymer with a weight ratio of 18%;

[0034] (3) adjust the pH value of the mixed solution in step (2) to 6 with an aqueous acetic acid concentration of 18%, and continue to add dropwise an aqueous acetic acid solution with a concentration of 18% to make the mixing in step (2) under constant stirring. When the pH value of the liquid drops to 4.2, the coacervate is precipitated, and the milk protein microcapsule finishing agent can be formed as the temperature of the dispersion liqu...

Abstract

The invention discloses a milk protein microcapsule finishing agent preparation method. The preparation method comprises 1, blending an aqueous solution containing a milk protein and gelatin and an aqueous solution containing Arabic gum to obtain a mixed solution containing 15-20wt% of the milk protein, 2, diluting the solution by water at a temperature of 40-50 DEG C and adding 18-25wt% of a maleic anhydride-isopropenyl ether copolymer with content of 4-6wt%, and 3, adjusting pH of the mixed solution in the step 2 to 6 through an acetic acid aqueous solution with a concentration of 18-22%, continuously and dropwisely adding an acetic acid aqueous solution with a concentration of 18-22% into the mixed solution in the step 2 along with continuous stirring so that pH is reduced to 4.2, carrying out coacervate precipitation and carrying out treatment through an aldehyde substance along with dispersion liquid temperature reduction so that a milk protein microcapsule finishing agent is formed. The invention also discloses a use of the milk protein microcapsule finishing agent.

Description

technical field [0001] The invention relates to a preparation method and application of vitamin milk protein microcapsule finishing agent. Background technique [0002] In recent years, the home textile industry has launched a "functional home textile products" war. Experts and enterprises are scrambling to develop various functional home textile products. Simple antibacterial sanitary textiles can no longer meet people's daily needs. [0003] Milk is one of the oldest natural beverages. It has 20 kinds of amino acids that make up human protein, 8 of which cannot be synthesized by the human body (9 kinds for babies, and more than adults are histidine). These amino acids are called essential amino acids. Amino acids are also very rich in minerals. In addition to the well-known calcium, they also contain a lot of phosphorus, iron, zinc, copper, manganese, and molybdenum. The most rare thing is that milk is the best source of calcium for the human body, and the ratio of calciu...
