Abstract
Chios mastic gum derived from the plant Pistacialentiscus L. var.chiais traditionally used as a food additive. Evidence has also suggested that mastic gum exhibits hepato protective cardio protective, anti inflammatory/antioxidant, and anti atherogenic properties. A total mastic extract without polymer was prepared after removal of the contained insoluble polymer in order to ameliorate solubility and enhance in vivo activity. In order to combine in a new colloidal dispersionthe bioactive-functional properties of mastic gum total fraction and the advantages of liposomes in food technology,the selection of a suitable carrier is crucial. Three different methods of preparation, thin-film evaporation, freezing thawing, and ethanol injectionwere used for the preparation of liposome?s consisting of phosphatidylcholine (PC) and cholesterol (CH). The effect of PC:CH molar ratio on the percentage of total mastic extract encapsulated was investigated. Total mastic gum extract/liposomes interaction was studied using Fourier transform infrared spectroscopy and differential scanning calorimetry. The effects of different preparation methods on the physicochemical properties of colloidal systems were evaluated by means of surface morphology by field emission scanning electron microscopy, and size distribution using a particle size analyser.
