Problems solved by technology

Studies have shown that the type and proportion of wall materials will affect the structure and size of microcapsules, such as cracks or pores on the surface of microcapsule particles, low embedding rate, poor oxidation stability of oil, etc.; in addition, in order to reduce the embedding rate of oil The problem of too low, the current microencapsulated fat powder has a core material ratio of about 20-60%, and the content is low, which limits the application range of oil to a certain extent

Abstract

The invention discloses a preparation method for microencapsulated lipid. The preparation method comprises the following steps: microencapsulating lipid; and performing carbon dioxide treatment on theabove material in the process of microencapsulation, wherein the carbon dioxide treatment comprises introduction of carbon dioxide into the material and refrigeration of the material. The preparationmethod effectively improves the embedding rate of lipid in the microencapsulated lipid and the stability of the lipid, and can better prolong the shelf life of corresponding final products. The invention also discloses the microencapsulated lipid prepared by using the method.

Description

technical field [0001] The invention relates to the technical field of microencapsulated oil production. More specifically, it relates to a microcapsule oil and a preparation method thereof. Background technique [0002] Most of the traditional oils are viscous liquids with poor fluidity. In some cases, it is difficult to mix them evenly with other raw materials, and they are easily exposed to the air due to the influence of light, temperature and other environments. A series of hydrolysis and oxidation processes , not only leads to the loss of nutrients, but even produces toxic substances, which limits its application in the food processing industry. In the prior art, it is known to use starch or flour to absorb grease to make powdered grease in order to solve the above problems. However, the powdered oils produced by these two methods have a common shortcoming. The oils are all adhered to the surface of the carrier and are still exposed to the air, and these processes in...
