Embodiment 1

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

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

[0033] (2) dilute with 40 DEG C of water, then add the aqueous solution of maleic anhydride and isopropene ether copolymer containing 4% by weight of 18% by weight;

[0034] (3) be that the aqueous acetic acid solution of 18% is adjusted with concentration and make the mixed solution pH value of step (2) drop to 6, under the situation of constantly stirring, continue to drip the aqueous acetic acid solution that concentration is 18% to make the mixing of step (2) When the pH value of the liquid drops to 4.2, the coacervate precipitates, and the milk protein microcapsule finishing agent can be formed as the temperature of the dispersion liquid ...

Embodiment 2

[0039] A preparation method of milk protein microcapsule finishing agent, comprising the following steps:

[0040] (1) mixing an aqueous solution containing milk protein and gelatin with an aqueous solution containing gum arabic to obtain a mixed solution, at this time, the milk protein in the mixed solution accounts for 18% by weight;

[0041] (2) dilute with 45 DEG C of water, then add the aqueous solution of maleic anhydride and isopropenyl ether copolymer containing 5% by weight of 20% by weight;

[0042] (3) adjust the pH value of the mixed solution of step (2) to 6 with a concentration of 20% acetic acid aqueous solution, under the situation of constant stirring, continue to add dropwise concentration of 20% acetic acid aqueous solution to make the mixing of step (2) When the pH value of the liquid drops to 4.2, the coacervate precipitates, and the milk protein microcapsule finishing agent can be formed as the temperature of the dispersion liquid is lowered and treated w...

Embodiment 3

[0047] A preparation method of milk protein microcapsule finishing agent, comprising the following steps:

[0048] (1) mixing an aqueous solution containing milk protein and gelatin with an aqueous solution containing gum arabic to obtain a mixed solution, at this time, the milk protein in the mixed solution accounts for 20% by weight;

[0049] (2) dilute with 50 DEG C of water, then add the aqueous solution of maleic anhydride and isopropene ether copolymer containing 6% by weight of 25% by weight;

[0050] (3) be 22% acetic acid aqueous solution adjustment with concentration and make the mixed solution pH value of step (2) drop to 6, under the situation of constantly stirring, continue to add dropwise concentration and be the acetic acid aqueous solution of 22% to make the mixing of step (2) When the pH value of the liquid drops to 4.2, the coacervate precipitates, and the milk protein microcapsule finishing agent can be formed as the temperature of the dispersion liquid is ...

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...
