» Asic Food Grade coatings have been used for centuries to prevent loss of moisture and to create a shiny fruit surface for aesthetic purposes.
» These practices were accepted long before their associated chemistries were understood, and are still carried out in the present day. Today, edible film use has expanded rapidly for retaining quality of a wide variety of foods, with total annual revenue exceeding $100 million.
» Most food consumed comes directly from nature, where many of them can be eaten immediately as we take them from the tree, vine or ground. However, with increased transportation distribution systems, storage needs, and advent of ever larger supermarkets and warehouse stores, foods are not consumed just in the orchard, on the field, in the farmhouse, or close to processing facilities. It takes considerable time for a food product to reach the table of the consumer. During time-consuming steps involved in handling, storage and transportation, products start to dehydrate, deteriorate, and lose appearance, flavorand nutritional value. If no special protection is provided, damage can occurwithin hours or days, even if this damage is not immediately visible . Edible films can provide either clear or milky (opaque) coatings, but consumers generally prefer invisible, clear coatings. Coatings can be obtained in various ways .
(1) by dipping or by brushing or spraying it with solution, so as to deposit the film directly on food surface
(2) by creating stand alone film from solution or through thermoformation for subsequent covering of food surface.
» The simplest way to apply a film is directly from solution. Depending on concentration of coating solution, the product will absorb an appropriate amount of coating material necessary to form the desired layer, which when dried, forms a protective layer at the food surface.
» Food compatible polymers are used by smaller food-makers, such as bakeries, and restaurants. In these applications, silicone food contact materials are used on cookware, baking pans and as sealants in food packaging. At home, silicones are also used in cooking and kitchenware, but beyond, they are actually used in tableware or as baby-bottle feeding teats.
» These products, whether for commercial or home applications, contain only food grade components and comply with strict national and international regulations. They are easy to use, safe to handle, odorless and do not modify food properties.
