preparation example Construction

[0027] The invention provides a kind of preparation method of modified phospholipid composite fatliquor, comprising the following steps:

[0028] (1) preparing hydroxylated sulfated phospholipids;

[0029] (2) Compounding the hydroxylated sulfated phospholipids, surfactants, and inert oils prepared in step (1); it contains 30-60 parts of hydroxylated sulfated phospholipids, 50-90 parts of surfactants, and 50 parts of inert oils ~90 servings.

[0030] As mentioned above, the hydroxylated sulfated phospholipids need to undergo hydroxylation of the phospholipids and then sulfate the hydroxylated phospholipids. Obviously, the introduction of hydroxyl groups into the phospholipid molecules can improve the hydrophilicity of phospholipids, which can be moderately dispersed even in cold water, and the obtained products have a light color due to the bleaching effect of hydrogen peroxide.

[0031] It can be understood that although hydroxylated phospholipids have introduced hydrophili...

Embodiment 1

[0057] The preparation method of the modified phospholipid complex fatliquoring agent provided by the invention.

[0058] Hydroxylation of phospholipids: Add 50 parts of soybean lecithin and 1 part of lactic acid into a three-necked flask equipped with a stirring device, a thermometer and a condenser, stir and heat to 50°C, then drop 5 parts of hydrogen peroxide into the three-necked flask, drop After completion, react at a constant temperature of 50°C for 2h. After the reaction is completed, the moisture is removed in vacuum to obtain milky white syrupy hydroxylated phospholipids.

[0059] Sulfation of hydroxylated phospholipids: 60 parts of prepared hydroxylated phospholipids were put into a three-necked flask, and cooled with cold water (water temperature: 0° C.). At the same time, 4 parts of concentrated sulfuric acid was slowly added with a dropping funnel at a rate of 5 drops / min, and the temperature of the liquid was 25°C during the dropping. After the sulfuric acid w...

Abstract

The invention provides a modified phospholipid fat liquoring complex agent and a preparation method thereof.The modified phospholipid is prepared from 30-60 parts of hydroxylation sulfating phospholipids, 50-90 parts of surfactant and 50-90 parts of inertia oil.Compared with the prior art, the modified phospholipid fat liquoring complex agent has the advantages that phospholipid is sulfated after being hydroxylated, a hydroxide radical is introduced into phospholipid molecules, hydrophilic groups such as sulfate groups and sulfonic acid groups are introduced, the nonsaturation of phospholipid is lowered, and the modified phospholipid fat liquoring complex agent has the advantages of being light in color, good in liquidity, excellent in emulsifying performance and dispersion, free of foreign taste, good in oxidation resistance and the like.

Description

technical field [0001] The invention relates to a composite fatliquoring agent and a preparation method thereof. Specifically, the invention provides a modified phospholipid composite fatliquoring agent and a preparation method thereof. Background technique [0002] Phospholipid is a natural amphoteric surfactant, which is a by-product of oil processing. It has abundant sources and low price. The unique molecular structure of phospholipid makes it have multiple functions such as emulsification, dispersion, penetration, softening, and wetting, so it is used in Food, paper, printing and dyeing, leather and many other fields. However, the currently commercially available soybean phospholipids have a low hydrophilic-hydrophobic balance number (Hydrophile-Lipophile Balance Number, HLB), poor hydrophilicity, and are difficult to disperse in water. It is easy to oxidize in the air, the color turns brown and produces odor, and the peroxide value increases, which affects the sensory...
