Edible Packaging Films and Application
C) The two companies have made the U.S. fiber membrane. It has many excellent properties, such as pH stability, and does not participate in the body's metabolism, Peijia gastrointestinal motility, has certain health effects, while the membrane barrier also made good in 50% RH conditions, the oxygen transmission rate than low density polyethylene (LDPE) is about 10 times lower. But with the humidity will increase its rate of increase of oxygen. This is a fibrous membrane tangled derivatives inadequacies. (-) Membrane protein, whether animal protein or plant protein can be used as raw material for edible films, the protein itself is essential for nutrition, safety, and this is the advantages of membrane proteins. Animal protein in the development of collagen membrane is the application of one of more of the edible film. Since the polarity of protein than the high fiber, high density binding energy after the film, so the oxygen barrier film is better than the tangled fibers, in 50% RH conditions, the oxygen permeability rate of collagen membrane almost polyester ( PET) films the same. Vegetable protein soy protein in the membrane film, corn protein film structure because of its non-linear rate caused by oxygen, can be used to add plasticizers, and other technology to make up. There is also gas permeable membrane protein ratio increases with increasing humidity shortcomings. (C) amylose starch films can be used to produce low oxygen permeability of water-based film, such as hydroxypropyl starch film after crystallization is high, energy density is also high end homes,christian louboutin shoes, so the oxygen permeability rate is lower, particularly valuable the high amylose film in high temperature environments will not drop barrier. Can effectively protect the food packaging. Some were almost hydroxypropyl starch and oxygen barrier film plastic film polyvinylidene ethylene dioxide (PVDC) the same oxygen barrier packaging can be applied to (d) Other edible film and composite film of carrageenan is also a Division algae polysaccharide material,mulberry outlet, edible films can be produced from citrus peel pectin extracted from plants such as the formation of three-dimensional network structure can be made into film after the barrier is also good, but they eat the real application of film not many were formed as a single group of edible film there are certain limitations in performance, for the packaging of edible films and better performance, a number of recent studies using a variety of membrane components of the mixtures and the use of two-story or two layer above the membrane complex system of membrane technology. Block each other hand to make edible films, mechanical strength are much improved, and achieved good results. Third, the preparation of edible edible film immersion method, emulsion method, coating method, emulsion + coating method. Studies have used methyl cellulose (MC),tory burch outlet, hydroxypropyl methyl cellulose (HPMC),franklin et marshall, and polyethylene glycol fermentation (PEG) dissolved in ethanol, the solution of a bearing temperature of 65 degrees Celsius plus stearin mixing acid and palmitic acid. Coating on the glass was dried at 100 degrees for 15 minutes into film. Finally, beeswax and then coated membrane thinning in the commitment of this surface. Results edible film made from 97% RH environment is still a very good barrier properties, and has excellent low temperature performance. Lipid membrane in which wax is used because it has excellent moisture resistance, low cost and generally considered safe non-toxic level (CGAS level) of these performance reasons. The film of methyl cellulose (Mc) Preparation of lipid emulsion that {film transmission rate lower than the MC membrane, then coated in the emulsion membrane lipid membranes more significantly reduced transmission rate. Preparation of the carrier film and the drying of different temperature, time, relative humidity and air flow will affect the film quality and performance, there is not one by one introduced in the practical application of edible film for packaging food and more medicines, such as corn protein films, whey protein film or cellulose film to package roasted peanuts, cashews and other nuts on the coating can slow down the oxidation rate of both the extension of its credit on the frame. Kara film coated with frozen shrimp, dessert topping, chicken, meat and other frozen food or microwave food. Frozen in time to prevent the consumption and oxidation. Cellulose membrane coated with fried chicken, fried meatballs, fried frozen convenience foods such big row, and not only extend the shelf life. The edible film packaging and these fried foods fried in the complex can prevent the seepage of oil adsorption surface and the food inside. To the effect of the soft crisp outside. Collagen membrane can not only packed sausage. And other meat products can be packaged. Forming uniform appearance. Food taste good, and natural animal casings and plastic casings compared to film. Has its unique advantages. In the drug's packaging, edible films as a tablet capsule drug packaging applications is greater now with the application of edible films to improve and expand its technology, of course, the present large quantities of edible films and application of industrial production is still small, as packaging material, the current number of edible films are inadequate. Can not compete with the plastic film,abercrombie et fitch, however, with the development of technology, I believe the near future, a new type of edible film packaging materials in a place. 95
