Associated scholarship(s):19/12372-6 - Polyphenols encapsulation obtained from the grape residue by supercritical antisolvent technique: Powder characterization, chemical stability and controlled release study in simulated gastrointestinal fluids, BE.EP.PD


The vegetal residue generated by the wine industry has been recognized as an excellent source of bioactive compounds due to its expressive amount of polyphenols, which have been shown to have protective effects against several chronic diseases, such as Cancer, cardiovascular diseases and inflammatory diseases, given by attenuation of oxidative stress and blocking of oxidative signaling pathways. However, sometimes the efficiency of the phenolic compounds is limited due to their poor solubility in aqueous medium and the low stability under severe conditions of acidity and alkalinity, and high temperatures, besides the low availability after oral administration. Starting from the mouth, the polyphenols begin their journey through the gastrointestinal tract, where they are submitted to several physical-chemical-biological transformations, of which they can lose their bioactivities completely. In order to overcome these problems, the development of polyphenol encapsulation systems (such as anthocyanins) through non-thermal, environmentally and humanly safe techniques are interesting to be employed in order to increase and improve the rate of release and its bioavailability to the target regions, especially when this regions is the lower gastrointestinal tract. In this context, this project proposes to investigate the antioxidant and anti-inflammatory properties of microparticles rich in grape skin extract produced by the emerging technique Supercritical Antisolvent (SAS) in the treatment of colitis, which is a type of inflammation of the large intestine, induced by acid 2,4,6-trinitrobenzenesulfonic acid (TNBS) in rats. In order to achieve this objective, the project was strategically structured in five steps: i) receigt, pre-treatment and characterization of the raw material (grape skin); ii) extraction and characterization of the extract; iii) extract encapsulation by the SAS technique and characterization of the microparticles; iv) administration of microparticles and unencapsulated dry extract in rats with induced Colitis; and v) analyzes of blood, tissues and faeces of animals. By performing these steps, it is expected that the microparticles produced by the SAS technique have great functional potential in vivo, thus contributing to the promotion of health and human well-being.
