Several edible films and coatings are formed from milk protein (whey, casein), wheat protein (gluten), soy protein and peanut protein. Therefore, the presence of a coating with a known allergen on a food must be also clearly labelled (Franssen & Krochta, 2003).

How are edible coatings made?
Edible films and coatings are produced mainly from biopolymers, including proteins, polysaccharides (carbohydrates and gums), lipids, and from food-grade additives.
What is edible film made of?
Edible films intended for food packaging have been produced from the washed EAEP residue combined with glycerol, different concentrations of citric acid (0%, 10%, 15%, 20%, 25%, and 30%), and sodium hypophosphite.
What kind of edible coating materials are used?
For edible coating purposes, various biopolymers are used as an antimicrobial hosting matrix, including chitosan, soy protein, whey protein, corn zein, methyl cellulose, hydroxypropyl methyl cellulose, starch, and other gums (Han, 2005; Min and Krochta, 2007).
What are the problems associated with edible coating?
➢ Disadvantages: Edible coatings have some disadvantages [27, 70]. o Thick coating can prohibit Oxygen exchange, causes off- flavour development. o Edible coatings have good gas barrier properties which causes anaerobic respiration due to this normal ripening process is disturbed in fruits and vegetables. o Some edible
What is edible coating?
An edible coating is defined as a thin layer of edible material, generally not exceeding 0.3mm, applied to the surface of foods in addition to or as a substitution for natural protective coatings. They are able to form a barrier against moisture, oxygen, UV-light and solute movement of the food1,2.

What is used for making edible films for wrapping candies?
Among the polysaccharides used for edibles films and coatings production, starch is the most widely used natural biopolymer, due to its easy processing, low cost, abundance, biodegradability, edibility and ability to form a continuous matrix [4].
Which of the following unmodified starch are used for making edible films for wrapping candies?
One of the marine polysaccharide used as base material for edible film preparation is agar.
What are the advantages of edible packaging?
Edible packaging eliminates the typical waste cycle and does not require any recycling. Since most edible packaging can be eaten or composted, it is very biodegradable, will not fill up landfills or recycling centers, or break down into microplastics in our soil.
