2. Gum base is the key raw material for chewing gum, and its composition is complex. The gum base is made of rubber, resin, filler, wax, emulsifier and antioxidant. The gum base is made of rubber, resin, filler, wax, emulsifier and antioxidant. Rubber was originally taken from natural tropical gum and other similar latex. Due to insufficient supply, it has been basically replaced by synthetic substances, such as styrene-butadiene rubber, butyl rubber and polyisobutylene rubber. Resin makes rubber dissolve and other substances dissolve into rubber, and also makes chewing gum bubble-blowing. Permitted resins used in gum base include polyvinyl acetate (PVA), partially dimerized rosin glycerol, partially hydrogenated rosin glyceride, partially hydrogenated rosin pentaerythritol ester, partially hydrogenated rosin methyl ester, vinyl acetate-vinyl laurate polymer, and synthetic resin. (including terpene resin), polyvinyl acetate (PVA), polymerized rosin glyceride, wood rosin glyceride, pentaerythritol rosin ester, etc. Generally, calcium carbonate or talcum powder is used as filler. Talcum powder should be used in chewing gum containing acidic spices. Waxes play a role in softening the chewing texture of soft chewing gum at all stages and reducing the melting point in the processing of gum base. Permitted waxes include palm wax, beeswax, polyethylene wax homopolymer, paraffin wax, etc. Emulsifier plays the role of affinity bonding of various gum base components. Licensed fatty acid glycerides, glycerol, pectin, lecithin, gelatin, hydrogenated vegetable oil, acetylated mono-and di-fatty acid glycerides, triacetin, stearic acid, etc. Antioxidants are used to extend the shelf life of gum base and chewing gum. Commonly used are butylated hydroxyanisole (BHA), dibutyl hydroxytoluene (BHT), propyl gallate (PG), tocopherol, etc.
3. Sweeteners are white sugar and glucose ground into fine powder. With the popularity of the concept of sugar-free food, sugar substitutes with low calorie and no tooth decay have replaced sucrose (cane sugar and beet sugar), glucose, maltose and fructose. Sugar substitute sweeteners include sugar alcohols (such as xylitol, sorbitol, maltitol and mannitol), starch hydrolysates (such as starch syrup, fructose syrup and malt syrup) and synthetic sweeteners (such as acesulfame, sodium cyclamate, saccharin, aspartame and sucralose).
4. Spices are usually various liquid spices with mint flavor and fruit flavor. Special flavor forms such as powder or microcapsule can be used to make chewing gum produce a taste with different release strength.
5. The softener is glycerol. Help improve the hardness of chewing gum and better bond various ingredients.
6. Pigment makes the appearance of chewing gum more attractive, which is generally matched with its fragrance.
7. Functional substances are related to the functional selling points of chewing gum. For example, healthy food chewing gum is added with vitamins, calcium and Chinese herbal ingredients.
