简要总结
Vitamin C is a water-soluble vitamin that is commonly used in food. It is utilized as an additive, because of its reducing and antioxidant properties. The usage of ascorbic acid in food is associated with a variety of biological activities such as the protection of oxidizable molecules, the retardation of enzymatic browning, oxygen scavenging, the prevention of nitrosamine production. The bioavailability and shelf life of bioactive components have both been improved by using encapsulation technology. Liposomes are vesicles that are simple models of highly complex cell membranes, consisting of lipid bilayers surrounding an aqueous core. Due to their unique biocompatibility and biodegradability, liposomes have attracted significant interest in the delivery and protection of both hydrophilic and hydrophobic compounds, such as vitamins. So liposomal encapsulated vitamin C helps to overcome the degradation of vitamin C due to high reactivity. It also improves the absorption into intestine by the controlled release of vitaminC.
