Single-layer microcapsules are the most commonly used form of microcapsules. However, regardless of the bacterial content on the particle surface or the water and gas barrier properties, single-layer microcapsules are weaker than double-layer or multi-layer microcapsules, making their stability relatively low.

Abstract
The invention relates to a microcapsule containing an active substance and a preparation method thereof, in particular to a multilayer microcapsule containing an embedded active substance and a preparation method of the multilayer microcapsule. According to the application, the microcapsule particles are prepared by a method of combining extrusion rolling core making (or centrifugal granulation core making) with fluidized spray coating; the preparation method comprises the following steps: firstly, preparing a primary pellet core by adopting an extrusion spheronization granulation method or a centrifugal granulation method, and then uniformly fluidizing a water-blocking coating layer material and a hydrophilic coating layer material to the surface of the pellet core. The prepared microcapsule particles are safe, free of toxic and side effects, small in particle size, rich in active substances and good in stability under the normal temperature condition, and have a slow release effect.
Description
technical field [0001] The invention relates to a microcapsule containing active substances and a preparation method thereof, in particular to a multilayer microcapsule containing embedded active substances and a preparation method thereof. Background technique [0002] In addition to providing people with energy, satisfying people's hobbies, and providing various components of the human body, many food components also have physiological activities and can regulate the functions of the human body, such as enhancing immunity and preventing diseases. Food scientists and food companies in many countries are paying more and more attention to the research and development of this functional food. [0003] Functional food is very important for improving physical fitness and nutritional intervention for chronic diseases. It covers nutritious food, special medical formula food, special dietary food, health food and functional general food, etc. It is the most market demand and develo...
