Research progress on microencapsulation of grape polyphenols

Grape polyphenols are important natural antioxidants in human diet, but its utilization in food industry is limited because of its low water solubility and easy degradation to various external environmental factors.Microencapsulation technology is a new technology which can encapsulate bioactive into carriers and helps to deliver it to the target sites, thereby to improve its bioavailability.Nowadays, microencapsulation technology has aroused great interest in the stabilization of grape polyphenols.In this paper, the latest research progress on microencapsulation of grape polyphenols was reviewed, the existing problems in the research field and the research prospect was also elaborated in order to lay a basis for the scientific research of the stabilization improvement of grape polyphenols in the future.
