Problems solved by technology

Studies have shown that when exposed to sunlight for 6 hours, the retention rate of vitamin K1 in milk powder is less than 30%.
The above patents all disclose the preparation methods of vitamin microcapsules or powders. Some of these methods involve expensive equipment and are generally difficult to realize. At the same time, they are less involved in the loss of vitamins caused by environmental factors, especially vitamins caused by temperature and light. The loss protection is more limited

Abstract

The invention discloses a photothermally stable vitamin microcapsule powder and a preparation method thereof; the raw and auxiliary materials of the photothermally stable vitamin microcapsule powder include: vitamins, oils, modified starch, starch sugar, stabilizer composition, pH adjustment agent, buffer, amylase and anti-caking agent; its preparation method is as follows: firstly dissolving vitamins in oil, adding astaxanthin in the stabilizer combination; dissolving modified starch in water, adding the above solution to obtain a primary emulsion; Dissolve starch sugar in water, add starch carbohydrase to control DE value of 70-85%, add the enzymatic hydrolysis solution to the above solution after inactivation, and carry out primary emulsification; dissolve gellan gum and konjac gum in the stabilizer combination in water , adding the above solution to carry out secondary emulsification; spray drying the emulsion to obtain vitamin microcapsule powder. The vitamin microcapsule powder obtained by the method provided by the invention has the characteristics of stable photothermal conditions and high embedding rate.

Description

technical field [0001] The invention belongs to the technical field of microcapsules, and in particular relates to a light-heat-stable vitamin microcapsule powder and a preparation method thereof. Background technique [0002] Vitamins, as the name implies, are a type of micronutrients that humans and animals must ingest to maintain normal physiological functions. Generally, vitamins cannot be produced by themselves and must be ingested from food. Although people and animals have a low intake of vitamins, vitamin deficiency can cause serious health problems, and adequate intake of vitamins is necessary for good health. In recent years, with the booming dietary supplement market and people's increasing emphasis on health, the demand for vitamins has also increased year by year. [0003] There are many types of vitamins, the common ones are vitamin A, vitamin D, vitamin E and B vitamins, etc. Different vitamins play different important roles in the body. For example, vitami...
