Gum base

The gum base is a substance that imparts foaming, plasticizing, chewing, and the like to the gum. Generally, it is mainly composed of polymer gelatinous substances such as natural rubber and synthetic rubber which are insoluble in water and fat, and is composed of a softener, a filler, an antioxidant and a plasticizer. The gum base has a sugar gum resin extracted from plants, a Dama resin; a paraffin wax extracted from petroleum, a microcrystalline paraffin; a natural material such as lanolin extracted from wool, and a polyvinyl acetate prepared by chemical synthesis. And polymer synthetic materials such as styrene-butadiene rubber. As a food additive added to gummies such as bubble gum and chewing gum, it can impart functions such as foaming, plasticizing and chewing. There are more than 30 kinds of products used in the world. Polyvinyl acetate is the most common and often used in combination with other basic materials. The gum bases allowed in China are paraffin, polyvinyl acetate, glycerol tri-rosin, styrene-butadiene rubber, etc., the maximum use of paraffin is 50g/kg, and it can be used for food packaging materials to prevent moisture and anti-stick. Anti-oil; Polyvinyl acetate is synthetically synthesized and is a cheaper base material for gums. Its maximum use is 60g/kg. However, it is hard to be cold when it is cold. About 5% polybutene is used to make up; glycerol tri-rosin ester can enhance the strength of the film, and has a natural resin mouthfeel, the amount is about 10% of the gum sugar; the amount of styrene-butadiene rubber used according to normal production needs. These gum bases are only for chewing, do not enter the human body, and are insoluble in water and fat, will not be absorbed by the body, and have no toxic effects. Gumdrops (sweet gum, bubble gum) are made of gum base, sugar, flavor, etc., and the gum base accounts for 20% to 30% of the gum. At the beginning of this century, rubber bases were almost exclusively derived from the natural tree latex of Chicle. As gum sugar became more popular, this material was in short supply and other similar latexes were used. In the future, synthetic materials are used. The gum base must be inert and insoluble and not easily soluble in saliva. As for the composition of the gum base is very complicated, there may be natural gums, synthetic rubber, resins, waxes, emulsifiers, softeners, gelling agents, antioxidants, preservatives, fillers and pigments, lakes, flavors and the like. The glue base can be made of bubble rubber, soft bubble glue, sour soft bubble glue, sugar-free bubble glue, chewing gum, sour gum, sugar-free chewing gum, etc., and according to the needs of manufacturers. , make the corresponding gum base.
