What is it about?
his study explores how discarded sunflower petals can be transformed into natural colorants rich in carotenoids, the compounds responsible for yellow and orange colors in many plants. The research investigates drying methods, extraction processes, and the role of carrier materials in producing stable powdered pigments. It also evaluates how these natural pigments can be incorporated into food products.

Why is it important?
Food manufacturers are increasingly looking for natural alternatives to synthetic colorants. At the same time, large amounts of plant materials are discarded during agricultural production. This research demonstrates how sunflower petal residues can be converted into valuable ingredients, creating natural food colorants while reducing waste and supporting a more sustainable food system.
Perspectives
The findings highlight the potential of agricultural by-products as sources of high-value natural ingredients. Future research could optimize production methods, improve pigment stability, and expand applications in foods, beverages, and nutraceutical products. This approach supports circular economy principles by transforming underutilized plant materials into useful products with commercial and environmental benefits.
