Abstract

Abstract: Clitoria ternatea petals are commonly used in health drinks and natural food colorants due to their antioxidant and antibacterial effects, as well as preventing cardiovascular diseases. In this study, the extract of Clitoria ternatea petals obtained under different temperature conditions was analyzed for their antioxidant components (polyphenols, flavonoids, anthocyanins) and their antioxidant capacity (DPPH free‐radical scavenging rate). The effects of the homogenization mode, ratio of lecithin to cholesterol, extract concentration of Clitoria ternatea petals, and extraction temperature on the diameter and uniform of liposome were also investigated to protect their active biological activities. Furthermore, the objective of this study was to improve the homogeneous size distribution of liposomes by probe‐type ultrasonication and high‐pressure processing (HPP) under the effect of pressure through hydrostatic pressure. The results showed that the extract of Clitoria ternatea petals for the best antioxidant effect was obtained at 50°C. According to the results of the Taguchi method, the optimal liposome particle size was the 1:0.15 ratio of lecithin to cholesterol, extract concentration was 0.7%, using the homogenization mode of the probe‐type ultrasonication. As a result, HPP was first employed as a useful method for the preparation of liposome and the improvement of particle size and polydispersity index via the preprocessing of probe sonication and showed considerable promise for use in encapsulation in the dairy beverage, pharmaceutical, and cosmetic industries.
