Application of Edible Packaging in Dairy and Food Industry

Abstract

There are number of food packaging materials such as glass, paper and cardboard, metals and plastic are available. However, the plastic is a mostly used non-biodegradable packaging material which causes environmental pollution. To overcome these problems, the biodegradable/edible food packaging is currently into focus for use. Edible packaging can be used in film as well as coating form. The materials are used for preparation of edible packaging varies in their function according to their sources. Some examples of edible film (packaging) are starch-based, collagen-based, zein-based, gluten-based, etc. Additives are added during the formation of film to enhance their positive role for packed food. Each additive has their unique role when combined with film material. These types of films have various functions, which would help to increase shelf life of food by acting barrier between food and external environment. The main advantage of edible packaging over synthetic packaging is that this may be safely eaten as a part of food product and thus, may reduce packaging waste and pollution. Edible film is physically and nutritionally better that the synthetic food packaging. Edible film used in food packaging should be passed by FDA as GRAS, then it can be used in food packaging. Edible packaging has several applications in dairy, food, confectionary, meat and also in pharmaceutical industry.
