Abstract[English]
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.[French]
Des formulations sont préparées par un procédé à haute énergie (par exemple, par sonication) à partir : d'une solution huileuse d'huiles comestibles (par exemple, de l'huile de tournesol à haute teneur en acide oléique) en tant que solvant, avec de la mélatonine (par exemple, 100 µM) et des agents antioxydants liposolubles comestibles (par exemple, 100 µM d'α-tocophérol), et d'une solution aqueuse d'agents de stabilisation solubles dans l'eau comestibles (par exemple, dextrine 1 % p/v). Ces formulations, appliquées en externe (par exemple, par pulvérisation) sont utiles pour une application de pré-récolte et/ou une conservation post-récolte de fruits ou de légumes, en particulier de fruits de pierre, et spécifiquement de cerises sucrées. Dans deux variétés de cerises sucrées et deux variétés de prunes, des conservations avec les formulations sont significativement meilleures que celles obtenues avec des solutions aqueuses de mélatonine, ou avec une formulation commerciale ou en l'absence de traitement.
