Title : Antioxidant Activity and Microencapsulation of the extract enriched in fruit anthocianins (peel and pulp) from Crysophyllum cainito L
The secondary metabolites are natural compounds that are produced by plants that have as main objective protect plants from biotic and abiotic stresses, besides great nutritional values and pharmacological for human diet and aromatic and dye properties. These compounds are separates in three major groups: terpenes, phenolic compounds and nitrogen containing compounds. Anthocyanins are phenolic compounds found in certain plants that give them their black, purple, blue, or red color, they present antioxidant activity which may be responsible for some biological activities including the prevention or lowering the risk of cardiovascular disease, diabetes, arthritis and cancer. Theses pigments are present in the fruits of the Chrysophyllum Cainito L. (purple Abiu). Based on prior knowledge of the substances present, this work was carried out to obtain the extracts rich in anthocyanins (pell and pulp), microencapsulation of the extracted content, to quantify the content of total anthocyanins, phenols and flavonoids, evaluation of the antioxidant activity and quantify the classes of anthocyanins present in the extracts by HPLC. The results of the study indicate that mainly the samples of peel fruit presented the highest results phenolic, flavonoids and anthocyanins content, efficiency to encapsulate and release the components present in the extract and the antioxidant activity. Thus, C. cainito can be considered a good source of antioxidants possible applications in the pharmaceutical, food and cosmetic industries, of which they show greater interest in these substances for the manufacture of products capable of offering benefits in fighting diseases and in aesthetic issues related to damage caused by oxidative species or that have free radicals in the composition.
