Abstract: Nuts and peanuts are nutritious raw materials, containing a high content of lipids, in addition to proteins and carbohydrates. They present a fatty acid profile of nutritional interest, mainly unsaturated, among them some are essential to the human diet. They are, therefore, raw materials that stand out for the combination of nutrients they present. The conventional oil extraction from these matrices is usually done by a mechanical process, which provides oil and press cake as a co-product. It is important to develop studies on alternative and green processes that bring advantages compared to the technology currently applied. The enzymatic aqueous extraction of oil from nuts and peanuts is a disruptive and clean process that allows increasing the oil yield and releasing side hydrolysates with characteristics and properties of interest for use in different areas, including the food industry. Thus, the objective of this study was to investigate the technological potentialities of the enzyme-assisted aqueous extraction, in order to obtain high-quality and yield oil from nuts and peanuts. The data were retrieved from the Espacenet® and Instituto Nacional de Propriedade Intelectual (INPI) patent databases, through an advanced search using a suitable terminology, in the “title” and “abstract” fields. The search was not time-limited. After reading the titles, abstracts and (when applicable) patent claims, 9 (nine) documents were selected, which addressed the extraction of oil by enzymes, the use of assistive processes and, in some cases, also obtaining side products. The data collected indicated that these patents of interest to the topic under investigation have been published since the year 2008, mainly by China. Only 1 patent has been granted. The inventions were related to the extraction of functional oil, mostly using the raw materials nuts, followed by pine nuts, macadamia nut, pili nut and peanut. In addition to the oil, three patents focused on the simultaneous extraction of protein hydrolysates and one focused on the extraction of nonhydrolyzed proteins. In some inventions, the use of ultrasound or microwaves as an assistive technology allowed to decrease processing time during enzymatic aqueous extraction. The survey revealed that this enzymatic method is promising, with application potentialities for the biotransformation of these oleaginous matrices. The results of this study contribute to the collection of data, as well as the generation of knowledge, within the production chain of nuts and peanuts, as a way of proposing technological innovations for this sector.
