Abstract

Microencapsulation is introduced as a key enabling technology to protect sensitive bioactive compounds, improve their stability and control their release in pharmaceutical, cosmetic, food and related products (Picot et al., 2015). The main objective of this project is to research and apply microencapsulation techniques to protect bioactive substances such as polyphenols and promote the development of personalised and sustainable products.  In it, polyphenols from by-products of the wine industry (grape peels) were selected as target bioactives due to their antioxidant and health-promoting properties. Different extraction techniques were applied, followed by microencapsulation using ionic gelation and coacervation methods with natural polymers such as alginate, pectin and hydroxypropyl methylcellulose (HPMC). The resulting microcapsules were incorporated into pilot formulations of functional foods and cosmetic products. Experimental results demonstrate that the selection of encapsulation technique and material strongly influences capsule size, stability and suitability for final applications.
