The confused grandmother was doing housework, and saw the little grandson holding the gum in his father's pocket with his feet, so he quickly took the little grandson aside, pretended to be angry, and said: "Be careful that your teeth are glued off by the gum." Smart Grandpa smiled with a newspaper to cover his face.
Smart Grandpa reminds: For thousands of years, Mexicans put some of the viscous gum secreted from trees into the mouth to chew, used to clean teeth, fresh breath, this is the earliest "chewing gum". In the 20th century, Americans used this sugar gum extracted from the heart fruit tree as a gum-based material, began the production and processing of chewing gum, and the product quickly swept the world and became one of the most popular candies around the world.
Smart Grandpa reminds: When you eat gum or bubble gum, you will definitely feel that they are not dissolved in the mouth, do not stick to the teeth, and will change shape with the teeth chewing. The secret of the difference between gum sugar and ordinary candy lies in the gum base that is not easily soluble in saliva, which is what we call the gum base.
Smart Grandpa reminds: Gum sugar base agent is to give gum and bubble gum foaming, plasticizing, chewable substances, generally based on natural gum and synthetic resin, plus a variety of waxes, softeners, gels, fillers, antioxidants, preservatives. Initially, people used natural rubber to make gum gum, Malay latex, etc., but due to limited production, it was gradually replaced by synthetic resin.
Smart Grandpa reminds: Natural gum is best with sugar gum gum, good gum-based plasticity, good ductility and elasticity, and easy to maintain fragrance. However, almost all of the bubble gum base uses synthetic resin styrene-butadiene rubber, which is because styrene-butadiene rubber has good film-forming and expansion properties, and can be blown into large and interesting bubbles.
