Liposome-Based Encapsulation of Extract from Wild Thyme ( L.) Tea Processing Residues for Delivery of Polyphenols.

This study developed phospholipid-based liposomes loaded with extract from wild thyme ( L.) tea processing residues to enhance polyphenol stability and delivery. Liposomes were prepared with phospholipids alone or combined with 10-30 mol% cholesterol or β-sitosterol.

Design and Characterization of Liposomal-Based Carriers for the Encapsulation of Fruit Extract: Gastrointestinal Release Behavior.

The increasing demand for natural compounds as an alternative to synthetic antioxidants and conservans has led to the utilization of secondary plant metabolites in the food industry, as these bioactive compounds possess great antioxidative and antimicrobial properties without side effects on human health. Despite this, the sensitivity of plant-derived compounds is a restrictive factor in terms of their full potential. The current research aimed to characterize rosehip-fruit-extract-loaded liposomes (non-treated and UV-irradiated) in terms of their density, surface tension, viscosity, chemical composition (FTIR and HPLC analyses), and thermal behavior.
