纳米喷雾干燥法制备食品生物活性成分微胶囊研究进展OACSTPCD

Functional foods and dietary supplements rich in bioactive ingredients can prevent and alleviate many chronic diseases.However,most of the bioactive ingredients have poor stability.They are easy to decompose and inactivated by light,heat,and oxygen during production,processing,and storage,and react with other ingredients in food.They are easy to degrade after entering the human gastrointestinal tract,showing a low bioavailability.The preparation of microcapsules is considered as a good strategy to improve the stabil-ity and bioavailability of bioactive substances.There are many methods to prepare microcapsules,among which the nano spray drying method is widely concerned because of its small particle size,good stability,and easier penetration into target cells.Therefore,this paper introduced the basic principle of nano spray drying,the differences between nano spray drying and traditional spray drying,and the appli-cation effects of various bioactive components of nano microcapsules prepared.Finally,this paper summarized the advantages of nano mi-crocapsules and proposed the limitations and research directions of nano spray drying.
