Análise físico-química das antocianinas presentes na casca da jabuticaba (Myrciaria cauliflora) e seu uso em cosméticos

Abstract

Jabuticaba (Myrciaria cauliflora) is a Brazilian fruit found in the Center-South region. However, it grows in most parts of Brazilian territory, being one of the national symbols of biodiversity. Dark-coloured and spherical-shaped, Jabuticaba contains a large amount of anthocyanin, an antioxidant molecule responsible for its pigment, which makes its peel an interesting by-product. Usually discarded, the peel contains several not researched bioactive compounds. Thus its use in the cosmetics industry emerges as an alternative for a sustainable reduction of residues. The high colouring power of the anthocyanin pigment is an interesting quality for products such as lipsticks, which are known for their huge variety of tones. This research will develop as a bibliographical review, obtaining extract containing anthocyanin from Soxhlet method and further Physico-chemical analysis of properties, for instance, chromatography test, humidity, ash content and pH. Technological quality tests will be done to rate organoleptic properties, spreadability, consistency, and water activity. The cosmetics showed satisfactory results, with good spreadability, emollience and color.
