Problems solved by technology

[0004] High-purity L-selenomethylselenocysteine ​​has a strong garlic-like odor and should not be added directly to health products
In addition, the amount of high-purity L-selenomethylselenocysteine ​​used in health products is small, and the level of added micrograms is not easy to control, and the uniformity of the final product is poor
Current limited simple embedding methods have poor stability and short shelf life

Abstract

The invention relates to an embedding and diluting method for L-selenium methyl selenocysteine. The method comprises the following steps: by taking high purity L-selenium methyl selenocysteine as a raw material, assisting beta-cyclodextrin to embed the L-selenium methyl selenocysteine by virtue of an ultrasonic method; then, by taking starch, dextrin, sodium carboxymethylcellulose and xanthan gum as auxiliary materials, boiling and granulating the mixture for secondary embedment; and finally forming a low purity L-selenium methyl selenocysteine microcapsule finished product which is stable in property and free of objectionable odors. The method provided by the invention has the advantages that the microcapsule is short in forming time and the efficiency is high; the production process is low in energy consumption and small in pollution; the product is good in embedding effect, stable in property and good in dispersibility after being dissolved; the low purity L-selenium methyl selenocysteine microcapsule finished product facilitates addition of selenium element into a health-care food, and the product added with the selenium element is good in mixing uniformity.

Description

technical field [0001] The invention belongs to the field of deep processing of agricultural and forest by-products. Background technique [0002] L-selenomethylselenocysteine ​​is a new type of selenium fortifier, which was recognized by the US FDA in 2002 as the latest generation of selenium source dietary supplements. Compared with other organic selenium, L-selenomethylselenocysteine ​​has the advantages of clear chemical structure, stable content and low toxicity. The chemical synthesis of high-purity L-selenomethylselenocysteine ​​is made from methyl α-acetamidoacrylate and sodium methylselenide through addition and enzymatic resolution. The appearance is powder or Granular solid, soluble in water, with garlic-like smell. [0003] In recent years, as people pay more and more attention to health, selenium-enriched products have been widely accepted, and selenium has become the biggest hotspot in the field of trace element research. Great potential for development. At...
