Abstract Cloud Point Extraction (CPE) technique was used to recover phenolic compounds from wine sludge wastes using lecithin as a surfactant. Lecithin is a safe natural product with no toxicity and, therefore, no separation of recovered phenolic substances from the surfactant system is required to use them in food systems. A progressive optimization sequence involving multiple recovery stages
