Abstract:

Liposomes and nanoliposomes as small vesicles composed of phospholipid bilayer (entrapping one or more hydrophilic or lipophilic components) have recently found several potential applications in medicine and food industry. These vesicles may protect the core materials from moisture, heat and other extreme conditions. They may also provide controlled release of various bioactive agents, including food ingredients at the right place and time. Potential applications of enzyme-loaded liposomes are in the medical or biomedical field, particularly for the enzymereplacement therapy, as well as cheese industry for production of functional foods with improved health beneficial impacts on the consumer. Encapsulation process has a recondite impact on enzymes. In fact, liposome preparation techniques may alter the pH and temperature optima, affinity of the enzyme to substrate (Km), and maximum rate of reaction (Vmax). In addition, in this paper, the impact of process variables on the kinetic characteristics of enzymes encapsulated in liposomes was investigated. Also, the effects of enzyme entrapment in liposomes, prepared by different methods, on the catalytic efficiency of enzyme, as well as its kinetic properties and stability compared to native (free) enzymes has been reviewed.

Keywords: Encapsulation, enzyme, kinetic parameter, liposome, morphology.
