abstract
- Since ancient times, different natural products have been used to enhance the attributes of foodstuffs, including sensory characteristics, nutritional value and also extend the shelf-life. More recently, these natural products have been also reported to exert beneficial biological properties in the health of consumers. For these reasons, numerous recent studies have been focusing on the valorization of bio-based extracts and compounds for their application in different industries, especially in the food sector.Moreover, considering that food-derived products not intended for consumption can be rich in bioactive compounds, many efforts have been made to employ by-products from food industry to extract such compounds and contribute to circular economy approaches.
