Grape (Vitis vinifera) is one of the most produced crops worldwide used mainly for wine production. Grape pomace is the solid waste produced after the alcoholic fermentation of wine. Grape and grape pomace content compounds with beneficial biological activities, such as phytosterols and phenolic compounds. Their concentration and profile of these compounds present great differences in different grape pomace, and this fact could be due to the use of different cultivars and varieties of the plants, differences in the edaphoclimatic conditions and differences in the extraction procedures used, for example. Terpenoid and phenolic compounds from vegetables and grape pomace have antibacterial and antifungal activities against several microorganisms. The predominant phytosterols in vegetables were β-sitosterol, campesterol, and stigmasterol. So, it is possible to reuse grape pomace as a natural antimicrobial agent. Even though, that extracting phenolic compounds or phytosterols will not solve totally the grape pomace problem, could be a partially solve by transform a waste to raw material, giving an environment friendly solution.
