Abstract

The invention discloses an L-Se-methylselenocysteine inclusion compound and a preparation method thereof. The L-Se-methylselenocysteine inclusion compound is prepared from the main raw materials of L-Se-methylselenocysteine, mono- and diglycerides of fatty acids and sucrose fatty acid ester as well as auxiliary materials of microcrystalline cellulose, beta-cyclodextrine and maltodextrin through certain processes. The L-Se-methylselenocysteine inclusion compound has the advantages of good inclusion effect, high uniformity, good taste-masking effect, no objectional odor after being dissolved and no influence on mouth feeling, is simple and safe in process, does not need water or organic solvent or a drying course, is time-saving and labor-saving, consumes few equipment, is simple in operation method, good in repeatability, low in equipment requirement, suitable for large-scale production and industrialization and wide in applicability, can be uniformly dispersed in milk beverage, and is not liable to moisture absorption.

Description

technical field [0001] The invention relates to an L-selenium-methylselenocysteine ​​inclusion compound and a preparation method thereof. Background technique [0002] Selenium is one of the essential trace elements for the human body. Selenium has the functions of anti-oxidation, protecting cardiovascular health, enhancing immunity, promoting growth, and anti-tumor. In addition, selenium also has detoxification effects on toxic metals. Long-term lack of selenium can lead to Keshan disease and Kaschin-Beck disease, and the phenomenon of selenium deficiency in the population is related to the low selenium content in the soil of the geographical environment in which they live and the insufficient intake of selenium in the diet. [0003] my country is a large selenium-deficient country. The low selenium content in most of the land in our country, the low selenium content in natural foods such as grains, and the differences in eating habits are the three main reasons for the ins...
