Fecha de publicación: 26/10/2023 Fuente: WIPO "stone fruits" They are prepared by a high energy method (e.g. by sonication) from: an oily solution of edible oils (e.g. high-oleic sunflower oil) as solvent, with melatonin (e.g. 100 µM) and edible fat-soluble antioxidant agents (e.g. 100 µM α-tocopherol), and an aqueous solution of edible water-soluble stabilizing agents (e.g. dextrin 1% w/v). These formulations, applied externally (e.g. by spraying) are useful for preharvest application and/or postharvest preservation of fruits or vegetables, particularly of stone fruits, and specifically of sweet cherries. In two varieties of sweet cherries and two varieties of plums, preservations with the formulations are significantly better than those reached with aqueous solutions of melatonin, or with a commercial formulation, or in the absence of treatment.
