Abstract: A process for producing a nanoemulsion formulation comprising the following main stages: (a) extraction of natural antioxidants from peels or seeds of fruits, vegetables or cereals, wherein the extraction is carried out with pure water, with a concentration of the extracted natural antioxidants with a vacuum distillation method between 0.5-15 inHg at 20-60° C. for 10-95 minutes until the concentration of the extracted natural antioxidants is between 10-50 wt % and then a tangential nanofiltration of the concentrated natural antioxidants; (b) encapsulation of the natural antioxidants; (c) formation of a nanoemulsion; and (d) cryodrying of the formed nanoemulsion.

Abstract: The present invention refers to a process for producing a nanoemulsion that consists of natural antioxidants encapsulated at a nanometric scale; the formulation of said product and its application for the preservation of different natural food products or derivatives, such as fresh or minimally processed fruits, vegetables and cereals and juices are disclosed. The formulation includes four main stages: (a) obtaining the natural antioxidants from fruit, vegetable and cereal waste; (b) encapsulation of the natural antioxidants; (c) formation of the nanoemulsion with natural antioxidants; and (d) cryodrying of the formed nanoemulsion.
