Description
Post harvest treatments with chemical fungicides and waxes are commonly used with fruit including citrus, apples and pears, to preserve freshness and extend shelf life. The label records treatment with two fungicides, Imazalil and Thiabendazole, and two Waxes (E904, and E914), which are used to prevent losses due to rind wounds or bruising. In the EU, all food additives are identified by an E number. E904 is shellac, which is a glaze. E914 (oxidised polyethylene wax) is a synthetic glazing substance providing a waxy coating to prevent water loss from a surface and provide other protection. Though these treatments are ?ǣGenerally Considered as Safe?ǥ (US FDA), their continuous use is raising concerns over health and environmental issues. Due to growing restrictions over the use of agrochemicals, there is increasing interest into research and development of antifungal edible coatings.
