Edible packaging films for domestic and international progress
Methyl cellulose as raw material, stearic acid, palmitic acid, beeswax, and agar as plasticizers, reinforcing agent obtained translucent,[link widoczny dla zalogowanych], soft, smooth, mouth or of the packaging films. High tensile strength, low moisture permeability, air permeability characteristics. Meanwhile, China's edible in the bagasse cellulose research and development on the packaging film also made good progress. 3. Edible plants and animals plastic packaging films such as edible film with gelatin gelatin, bone glue, shellac, vegetable gum, such as glucomannan, carrageenan, pectin, sodium alginate, Prussian blue as a substrate, glycerol , polyols, such as sorbic acid ester plasticizer, a system for various uses of edible packaging film. Japan edible plants and animals plastic packaging film has been in development and application of world leading level on the four countries Industrial Technology Research Institute, Institute of Biochemistry, Lin Yuan, Osaka Chemical Taijin, Mitsubishi Rayon Company has developed a variety of plants and animals Edible plastic packaging films are transparent, high strength, printability, heat sealing, gas barrier, good moisture resistance characteristics of water has been used for seasoning, sweet ignorant of the material, soup, oil and other food packaging. All domestic Kan Jian, CHEN Yong-gelatin edible films such as mechanical strength and heat seal strength, Li Hongjun, He Juvenile Non film-forming properties of sodium alginate and the membrane mechanical properties, LUO cut on glucomannan and other film-forming edible films Research based and processes for the industrial production of edible films and application of foundation. 4. Edible Chitosan Chitosan membrane evening bag shrimp, crabs, insects, crustaceans and other extracts. The packaging film by the U.S. Agricultural Research,[link widoczny dla zalogowanych], Agricultural Research Center in California developed a success. Mainly used for packaging fruit and vegetable foods. Chitosan lauric acid with 12 carbon atoms together. Can generate a homogeneous edible film, the thickness of only 0.2-0.3 mm. Therefore, transparency is high, for peeled or sliced fresh fruit packing, preservation of good. Disk i: j: a: a ~ 'a:' Pan B Guo Fu reference date more complex Cao Zhi hand drum used by peddlers Cou edible packaging film research and application is the current trend. Department of Food Engineering at the University of Wisconsin research and development of edible packaging material, the different proportions of protein, fatty acids and polysaccharides together to create into an edible packaging films. The packaging film, the greater the fatty acid molecules, the slow escape of moisture resistance performance, the better,[link widoczny dla zalogowanych], and because membrane protein, polysaccharide types, different content, film transparency, mechanical strength, printability, heat sealing,[link widoczny dla zalogowanych], gas barrier resistance, moisture resistance performance of different water,[link widoczny dla zalogowanych], so to meet the different needs of food packaging. China successfully developed the composite packaging film with corn starch as the base material, plus sodium alginate or chitosan, which together with a certain amount of plasticizer, tackifying Jing, preservatives, processed by a special process that can be used Preserves , cakes, instant noodles soup and other food products in a variety of convenient packaging. Its main feature is a strong tensile strength and elongation. And a very good water resistance. Such film is based on natural resources, molasses, oil and other raw materials, produced by microbial fermentation of a hydroxy-3-butyl, hydroxy pentyl 3, 4 hydroxy butyl lactone, etc. has been made of edible packaging polyester film . Current research and development of microbial copolyester products have a British ICI Company 3 and 3-hydroxy butyl hydroxy valerate (90%) of the copolymer of a polyester film and 3-hydroxy butyl and 4-hydroxy-BA copolymer of a polyester film and Massachusetts Institute of Technology (/ fil1) the development of aliphatic polyester copolymer membranes. Both of these films have good optical properties of ordinary plastic film, transparent and glossy. Physical performance, light density, chemical stability. Easy to shape processing and maintenance of a wide range of advantages, but also has edible and completely biodegradable, so by the national attention. References l difference in Pian translation.
