Food Industry

• Food Preservation: β - Cyclodextrin can encapsulate easily oxidizable and volatile food components to form stable inclusion complexes, thereby improving the stability of these components and prolonging the shelf - life of food. For example, when oils and vitamins are encapsulated by β - cyclodextrin, their oxidation and deterioration can be prevented, and the flavor and nutritional components of food can be maintained.

• Removal of Off - Flavors: It can encapsulate off - flavor substances in food, such as fishy smell and mutton smell, thereby improving the odor and taste of food. When processing aquatic products and meat products, adding an appropriate amount of β - cyclodextrin can effectively remove off - flavors and improve the quality of products.

• Improvement of Food Texture: β - Cyclodextrin can interact with certain components in food, affecting the texture and rheological properties of food. In baked goods, it can interact with starch to delay the retrogradation of starch, keep bread, cakes and other products soft in texture, and prolong their shelf - life.

Pharmaceutical Industry

• Drug Carrier: β - Cyclodextrin can encapsulate poorly soluble drugs in its cavity, increasing the solubility and stability of drugs and improving the bioavailability of drugs. For example, some lipophilic drugs such as vitamin D and estrogen, when formed into inclusion complexes with β - cyclodextrin, can be better dissolved in water, which is convenient for the preparation of oral preparations or injections.

• Reduction of Drug Irritation and Toxicity: For some drugs with high irritation or toxicity, the encapsulation effect of β - cyclodextrin can reduce the direct contact between the drug and the gastrointestinal mucosa, thereby reducing the irritation and toxicity of the drug. For example, garlic oil has strong irritation. After being made into β - cyclodextrin inclusion complex, the irritation to the gastrointestinal tract can be reduced, which is convenient for patients to take.

• Control of Drug Release: By selecting appropriate preparation methods and conditions, the release rate of drugs in β - cyclodextrin inclusion complexes can be adjusted to achieve slow - release or controlled - release of drugs. For example, when ibuprofen is made into β - cyclodextrin inclusion complex, the drug can be slowly released in the body, prolonging the action time of the drug and reducing the number of doses.

Cosmetic Industry

• Stabilization of Cosmetic Raw Materials: β - Cyclodextrin can encapsulate easily - deteriorated components in cosmetics such as fragrances, pigments and vitamins, preventing them from being decomposed, discolored or deteriorated by light, heat, oxygen and other factors, and improving the stability of cosmetic raw materials. For example, when natural fragrances are encapsulated by β - cyclodextrin, the volatilization of fragrances can be reduced, and the fragrance can be more lasting.

• Improvement of Cosmetic Skin Feel: β - Cyclodextrin has certain hygroscopicity and moisturizing property, which can form a protective film on the skin surface, increase the water content of the skin, and make the skin feel softer and smoother. At the same time, it can also adjust the viscosity and rheology of cosmetics, improving the spreadability and application of cosmetics on the skin.

Chemical Industry

• Separation and Purification: β - Cyclodextrin can be used to separate and purify specific components in mixtures based on its encapsulation selectivity for different molecules. For example, in petrochemical industry, it can be used to separate mixed hydrocarbon compounds; in fine chemical industry, it can be used to separate and purify fragrances, drug intermediates, etc.

• Catalyst Support: β - Cyclodextrin can be used as a support for catalysts, loading the active components of catalysts on its surface or in the cavity to improve the stability and selectivity of catalysts. For example, loading metal catalysts on β - cyclodextrin and using them in organic synthesis reactions can improve the reaction efficiency and the selectivity of products.

Agricultural Field

• Slow - Release of Pesticides: Making pesticides into inclusion complexes with β - cyclodextrin can slow down the release rate of pesticides, prolong the duration of pesticide efficacy, reduce the amount of pesticides used and the number of spraying times, and reduce the pollution of pesticides to the environment. For example, when pesticides such as insecticides and fungicides are encapsulated by β - cyclodextrin and applied to crops, the pesticides can continue to play a role for a long time.

• Plant Growth Regulators: The inclusion complexes formed by β - cyclodextrin and some plant growth regulators can improve the stability and biological activity of plant growth regulators, and regulate the growth and development of plants. For example, when plant growth regulators such as gibberellin and auxin are encapsulated by β - cyclodextrin and used to treat seeds or seedlings, they can promote the germination, rooting and growth of plants.
