Abstract

Color is one of the main sensory attributes for consumers, directly affecting their perceptions of products. The color additive market is mainly composed of colorants of synthetic origin, however, the population's awareness of the need for sustainability, has been boosting the consumption of natural additives. Carotenoids and Azaphilone polyketides are natural colorants, with a wide variety of tones, which can range from red to yellow, synthesized by yeasts and filamentous fungi, respectively. Along with their vibrant color, carotenoids present antioxidant activity, while the extract containing polyketide colorants presents antimicrobial activity. These characteristics make these compounds even more attractive for the cosmetic and pharmaceutical industries. Given this context, this project proposes the evaluation of the application of carotenoids produced by the yeast Rhodotorula glutinis and polyketides produced by the filamentous fungus Talaromyces amestolkiae, obtained by submerged cultivation, in the development of cosmetic formulations. This proposal will contribute to the development of more sustainable, natural, vegan and functional products, reducing risks to human health and environmental impacts associated with synthetic colorants.
