Type of edible film:
(1) a protein-type edible film protein-based film, for example, a soybean protein packaging film, which is an edible film made of soybean protein, an added enzyme, and other treating agents, is used for food packaging, and can maintain the moisture of the food, and It prevents oxygen from entering and can be cooked with food. There are three types of protein sources: 1 collagen sea film, which is based on animal protein; 2 milk-based film, which is based on whey protein or cheese protein or a combination of the two; 3 grain film, Then based on soy protein, zein, wheat gluten, rice glycoprotein, peanut protein, egg protein, fish protein and the like.
(2) A polysaccharide-type edible film polysaccharide-type edible film, such as a chitosan edible packaging film. The shellfish extract polysaccharide is used as the main raw material, and chitosan and lauric acid are combined to form a uniform edible film with a thickness of 0.2-0.3 mm. The peeled fruit or fruit pieces are packaged with the film and have a good preservation effect. The polysaccharide base film can be divided into four types according to the difference of the base material: 1 cellulose film, which can be based on methyl cellulose, hydroxypropyl methyl cellulose, pectin, etc.; 2 chitosan film
The shellfish extract monosaccharide is used as the base material; the 3 moldy polysaccharide membrane is based on the biopolymer compound seedling polysaccharide produced by fermentation of potato, potato, cassava, broken rice and other agricultural by-products; 1 starch membrane , based on grain starch. Among the edible packaging materials such as corn, wheat, potatoes, and potatoes, the corn starch is modified into edible packaging materials, and the processing technology and practical application are mature, and can be made into films. .
(3) Fat type food film Fat type base film is divided into three categories according to the difference of fat source: 1 vegetable oil type film, which is resin acid, linoleic acid, palm oil, sunflower oil, coconut oil, safflower oil, respectively. , vegetable oil, etc. as the base material; 2 animal type film, which is based on anhydrous floating film, lard, etc.; 3 waxy film, which is based on beeswax, small turbid wax, carnauba wax, etc. Fresh food is preserved by film coating.
(4) The composite edible film composite film is a composite component which is required to be combined with a protein or a polysaccharide fat in a mass ratio, for example, a corn starch alginate or a chitosan composite packaging film. It is based on corn starch and is supplemented with sodium alginate or chitosan. It is compounded with plasticizer, tackifier and preservative. It can be processed by special techniques. It can be used for dried fruits, cakes, instant noodle soup and various conveniences. Inner packaging of food.
