Microencapsulation granulation is the use of wall material (or encapsulated material) to coat the heart material (or encapsulated material) in it. After microencapsulation and embedding, the wall material can protect the wrapped material and isolate it from the unsuitable environment, so as to keep the original color, fragrance, performance and biological activity to the greatest extent, and prevent the loss and destruction of nutrients. In addition, some materials can mask their own peculiar smell after being microencapsulated, or transform from a liquid that is not easy to process into a relatively stable solid form, thereby greatly preventing or delaying the occurrence of product deterioration and improving product quality. In addition, the microencapsulated products can meet the requirements of customers for particle size, and at the same time have better solubility than general traditional spray-dried products.
