Abstract: The reduction of production costs has been a widely discussed issue in the context of animal production currently. Diet formulations often use feed ingredients that contain antinutritional factors, such as phytate and protease inhibitors, which decrease nutrient bioavailability and hinder digestion in monogastric animals. In light of this, technological alternatives have been sought for the extraction and purification of exogenous enzymes, such as phytases, in order to improve food quality, reduce costs, and enhance nutrient digestibility by partially or completely eliminating the antinutritional factors present in the diets of poultry and swine. In this regard, this literature review aims to present an article that addresses advances in methods for enzyme separation and purification, with emphasis on the aqueous two-phase system (ATPS), which has been widely used for enzyme separation due to its low cost compared to other purification processes.
