A method of post-harvest treatment on fruit, comprising applying to the fruit an edible aqueous formulation comprising:

• between 1 and 30% by weight of lecithin;
• between 0.1 and 20% by weight of a polysorbate;
• between 0.1 and 20% by weight of a sorbitan ester;
• between 0.1 and 20% by weight of a sucrose ester of fatty acids, between 0.1 and 20% by weight of a sucrose glycerids of fatty acids;
• or between 0 and 20% by weight of a cellulose derivative;
• between 0 and 30% by weight of a glycol;
• between 0 and 20% by weight of an alcohol;
• and
• between 0 and 0.4% by weight of a defoamer;
• wherein all amounts are with respect to the weight of the formulation, wherein applying is done during any one of the stages of a post harvesting period.
