Abstract

The increasing interest of the industry by phenolic compounds has justification in the knowledge of the beneficial effects to the health related to the consumption of these compounds. Obtaining extracts rich in bioactive phenolic compounds from agroindustrial coproducts can be a way to add value to waste, and to develop sustainable processes in the food production chain. The use of environmentally friendly technologies to obtain bioactive compounds such as enzyme and microwave assisted extraction is the proposal of this Project. The proposal is develop a clean process to recovery of phenolics bioactive compounds from the California olive oil industry coproducts . This industry seeks to expand based on sustainability and productivity and the recovery of bioactive compounds from the production residues can generate products of high added value for the food and cosmetic industry. The optimization of the extraction process variables will be performed based on the phenolic composition of the extracts as well as on the maximization of antioxidant and antimicrobial activity of the extracts obtained. The application of these technologies is possible in several types of agroindustrial residues and complements the projects that I have been developing in Brazil obtaining phenolic extracts of residues from the orange, soy and grape industries.
