Problems solved by technology

[0002] Thiamine dilauryl sulfate, a salt of vitamin B1, is rarely reported, and there is no such product in China. The commonly used vitamin B1 in the past was thiamine hydrochloride, which was added to many foods as a nutritional enhancer Among them, thiamine hydrochloride has good water solubility, is easy to decompose by moisture absorption, and decomposes when exposed to ultraviolet rays. It is unstable when heated above PH5.5, and it is not easy to disperse in non-aqueous products. There are many limitations in use. This is a problem. where the

Embodiment Construction

[0010] The present invention will be further described in combination below.

[0011] The present invention is carried out according to the following steps:

[0012] (1) Thiamine or thiamine salt and lauryl sulphuric acid or lauryl sulphate are stirred at a temperature of 35 to 55°C for 0.2 to 10 hours to obtain a reaction mixture; among them, the common ones are the easiest to obtain economical The lowest cost reactants are thiamine hydrochloride and sodium lauryl sulfate. The reaction ratio is 34 g / 100 ml of thiamine hydrochloride aqueous solution and 57 g of sodium lauryl sulfate; or 34 g / 100 ml of sulfur Add 54 g of potassium lauryl sulfate to the aqueous solution of amine hydrochloride; or add 61 g of lauryl sulfuric acid to the aqueous solution of 34 g / 100 ml of thiamine hydrochloride.

[0013] The thiamine or thiamine salt (called "thiamine") used in the above reaction can use free thiamine, thiamine hydrochloride, sulfate and other inorganic and organic salts of thiamine. ...

Abstract

The invention discloses a preparation method of thiamine dilauryl sulfate vitamin B1 salt, which comprises the steps as follows: subjecting vitamin B1 or vitamin B1 salt and lauryl sulfuric acid or lauryl sulfate to reaction to obtain a mixed solution, optionally treating, crystallizing, drying wet blocks containing the thiamine dilauryl sulfate vitamin B1 salt via a vacuum drier, and drying via a fluidized bed granulation drier to obtain granular thiamine dilauryl sulfate vitamin B1 salt. The thiamine dilauryl sulfate vitamin B1 salt crystalline particles have uniform shape and good dispersity, and can be directly added to various foods.

Description

Technical field [0001] The invention relates to the field of preparation of nutritional fortifiers, and more specifically, to a method for preparing thiamine dilauryl sulfate. Background technique [0002] Thiamine dilauryl sulfate is a salt of vitamin B1. There are few reports. There is no such product in China. The commonly used vitamin B1 is thiamine hydrochloride, which is added to many foods as a nutrient fortifier. Among them, thiamine hydrochloride has good water solubility, is easy to absorb moisture and decompose when exposed to ultraviolet rays, it is unstable when heated above pH 5.5, and it is not easy to disperse in non-aqueous products. There are many limitations in use, which is a problem. Where. Summary of the invention [0003] The technical problem to be solved by the present invention is to overcome the shortcomings existing in the prior art and provide a manufacturing method of thiamine dilauryl sulfate. [0004] The manufacturing method of thiamine dilauryl ...
