Application of microencapsulation technology in health food

Microcapsule technology is a kind of micro- or nano-scale micro-particle products, which uses natural or synthetic polymer materials as micro-capsule wall materials to encapsulate solid and liquid pharmaceuticals, foods and chemical raw materials into capsule core materials. New technology, new technology. Has been applied in many fields such as medicine, food, fine chemicals.

Health food refers to foods that claim to have specific health functions or to supplement vitamins and minerals, that is, suitable for consumption by specific people, have the function of regulating the body, are not for the purpose of treating diseases, and do not produce any acute or subacute to the human body. Or food that is chronically harmful. However, some health foods have greatly shortened their shelf life due to their special ingredients and tissue morphology. 宦银根[1] used microcapsule embedding method in the production of natural ginger juice encapsulated health care products, and obtained microcapsules with higher yield. Health products. In the production of health oil-linseed oil, Tian Yuan [2] also used microencapsulation method to microencapsulate linseed oil with β-cyclodextrin as wall material to overcome the limitations of linseed oil and obtain access. Flax oil health products and high-quality raw materials with convenient, stable nature, good fluidity and high nutritional value.

However, there are many methods for making microcapsules, such as spray drying method, spray cooling curing method, air suspension spraying method, etc., wherein the high voltage electrostatic method is the most advanced microcapsule embedding technology method researched in the world, and the micro-encapsulation technology is formed. The capsule particles have a regular spherical shape, uniform size, smooth surface and good quality (see Figure 1). The MP-180 high-pressure microcapsule molding device (see Figure 2) produced by Shanghai Baosheng Company has the advantages of compact structure, simple operation and long release time (see Figure 3).
