What are the characteristics of microencapsulation technology?

1. Effectively reduces the reaction of active substances to external environmental factors (such as light, oxygen, and water);
2. Reduces the diffusion and evaporation of the heartwood to the environment;
3. Controls the release of the heartwood;
4. Masks the peculiar smell of the heartwood;
5. Changes the physical properties (including color, shape, density, and dispersibility) and chemical properties of the heartwood.
For the food industry, it allows all-natural flavoring ingredients and physiologically active substances to be incorporated into food systems while maintaining their physiological activity. It simplifies many traditional processing methods and solves many processing problems that cannot be solved by conventional technical means.
1. Powdering: Solidifying easily processed and stored gaseous and liquid raw materials to improve their solubility, fluidity, and storage stability, such as powdered flavorings, powdered edible oils and fats, and powdered ethanol. For example, using liquid oil as the core material and selecting an appropriate wall material, microencapsulation technology can produce solid powdered oil, which can be easily added to various food raw materials. It has been reported that abroad, dozens of microencapsulated powdered oils are used as food industry raw materials, applied to various nutritional health foods or functional foods.
2. Reducing volatility: Preventing the volatilization of flavor components and reducing flavor loss.
3. Reducing toxicity: Reducing the toxicological effects of food additives, such as ferrous sulfate and aspirin. After encapsulation, the release rate can be controlled to reduce gastrointestinal side effects. In the pharmaceutical industry, microencapsulation technology can be used to manufacture targeted preparations to achieve targeted release.
4. Improving the stability of substances (easily oxidized, easily photodegraded, easily affected by temperature or moisture): After many food additives are made into microcapsules, due to the protection of the wall material, they can prevent oxidation and avoid or reduce the influence of ultraviolet light, temperature, and humidity, ensuring that nutrients are not lost and special functions are not lost.
5. Enabling the uniform mixing of incompatible components: Using microencapsulation technology, components that may react with each other are made into microcapsules separately, making them stable in a system. Various effective components are released in an orderly manner and act at the corresponding time to improve and enhance the flavor and nutrition of food products. For example, some powdered foods are very sensitive to acidulants. Because acidulants absorb moisture, they cause the product to clump; and the pH value varies greatly where the acidulant is located, leading to changes in the surrounding color, making the appearance of the entire package unattractive. After the acidulant is microencapsulated, it can delay contact with sensitive components and extend the shelf life of the food.
6. Masking taste: Some nutrients have unpleasant odors or tastes, which can be masked using microencapsulation technology. This type of microcapsule product does not dissolve in the mouth but only in the digestive tract, releasing the contents and exerting its nutritional effect.
7. Isolating active ingredients: Maintaining the active effect of micronutrients and physiologically active substances in food on the human body.
8. Controlling the release and action time and quantity of the core material: Microcapsule products, through a pre-designed dissolution and release mechanism, can provide a special release method
