NEW RESEARCH ARTICLE: Microwave pretreatment to improve extraction efficiency and polyphenol extract richness. Effect on antioxidant bioactivity

Microwave assisted extraction advantages are widely recognised. However, its implementation at an industrial scale is restricted due to microwave limitations. In this work, a microwave pretreatment is proposed as an easy scale-up alternative. The double effect of this pretreatment on extraction yield and on product richness is assessed. Microwaves accelerate the extraction kinetics of most […]

[Paper]: Using different natural origin carriers for development of epigallocatechin gallate (EGCG) solid formulations with improved antioxidant activity by PGSS-drying

Epigallocatechin gallate (EGCG) is the catechin with the highest antioxidant activity present in green tea. Nevertheless, due its low bioavailability, it is necessary to develop EGCG formulations capable of improving its stability resulting in increased bioavailability and thus higher biological activity of this catechin (e.g. antioxidant activity). The purpose of this work was the formulation […]
