The new century, China's food industry, the first major innovation initiative: since January 1, 2000, introduced a "degradable" in Food Packaging Materials, and gradually ban the use of non-degradable materials to control disturbing "white pollution", for the next "edible packaging" lay the foundation for the development of edible packaging is the world's food industry the main trends of new technology development, it has been involved a wide range of applications, such as Casings , Fruit wax, sugar, rice paper, clothing and ice coated tablets and so on.
As edible packaging versatile, environmentally sound, are easy for human consumption, so the food industry in recent years competing developed countries, new products, new technologies are emerging, foreign edible packaging show the following dynamic.
Dynamic one: the latest research topics
Eight universities in the United States at least set up a Department of edible food packaging research topic. University of Minnesota Department of Food Science and Nutrition has a development team, specializing in different components with fresh edible food films. Clemens University of Agriculture and Biological Engineering Department will carry out a wide range of membrane protein edible film materials research. University of Wisconsin research team led by Fei Nima, the use of polysaccharides, and fat developed moisten as much as double the edible film of polyethylene film, and use it for a "simulation of food" to achieve superior results.
French research team led by Ge Bote also carried out extensive studies of edible films. , Japan, Germany, the same is also carried out extensive research in this field. Particularly noteworthy is the United States and Japan in this field has accumulated a large number of patented technologies.
Dynamic 2: Multi-edible film Edible packaging is one of the emerging area of multifunctional development of edible packaging films, primarily by natural water-soluble polymer membrane, or a combination of hydrophobic substances and Emulsifier As the membrane liquid, with addition of various preservatives, even with addition of enzymes and other bioactive materials, dipping in the agricultural or food surface, dried to form a layer of almost invisible film, the film has a resistance layer of wet gas barrier , pest control, antiseptic, antioxidant, anti-browning, disease resistance of different nature, and edible.
, For example, thin-skinned fruits, large leafy vegetables and cauliflower in plastic wrap often sent together with the import of fruit and vegetable, and asked not to be found. Cakes, candy and some livestock products within the package within the package also can be dissolved in mouth, delicious transparent and have adequate moisture resistance, only the function of oxygen and anti-corrosion and other more practical and high-end.
Dynamic III: biodegradable artificial casing artificial casing of one of the areas are developed
The one hand, the artificial synthetic casings, such as nylon casing, polychlorinated Asia, such as vinyl casings have been widely practical application. Their strength, resistance to boiling, flexible in use before the unnecessary flooding; the other hand, synthetic materials, synthetic casings are not edible, thus artificial edible casings provide a good opportunity for development.
Have invented the edible artificial casings and collagen casings fibrin. It is divided into two types, named Naturin and Devro, they are made with Kraft pulp degeneration of collagen protein group, and then made pressure extrusion. However, "Na-turin" in the denaturation temperature and the stability of sub-natural casings, and "Devro" the contraction of it is too high, so have to improve.
