Hello everyone, welcome to "Sodium Chloride NaCl", here every day will share some popular science knowledge, like friends please pay attention.
Guangxi, located in South China, is located on the southeast edge of the Yunnan-Guizhou Plateau, and belongs to the subtropical monsoon climate and tropical monsoon climate. Due to the unique environmental conditions and geographical advantages, it has created a wealth of forest resources here, especially the Masson pine is the most famous. By using pine resin extracted from pine trees as a raw material, important raw materials such as medicine, chemical industry, and food can be produced in different processing methods.

Pine resin is a transparent, brittle solid natural resin, which is an oil flowing from the inside of a pine trunk, melted into a watery state after high temperature, and dried into a lumpy solid, it has no fixed melting point, the color is burnt yellow and crimson, and has a special fragrance.

But you know what? This seemingly inedible substance turned out to be the raw material for making chewing gum!
After the pine resin is distilled, some impurities are removed to obtain a lighter rosin fragrance. This light-colored rosin is then esterified with food grade glycerin to form rosin glycerides. Finally, hydrogenated rosin glycerides are obtained by hydrogenation, which can become the raw material for making chewing gum.
Rosin glycerides
Hydrogenated rosin glycerides are then heated and melted together with natural sugar gum, gum, wax, vinyl acetate, etc. and then spices, sugar and pigments are added to make chewing gum.
chewing gum
Chewing gum is a popular sweet, especially among children and young people. In fact, chewing gum is also one of the oldest candies in the world. Archaeologists have found that long before there are historical records, human beings like to chew natural gum for fun, which is the most primitive "chewing gum".
Natural gum
The texture of chewing gum has a strong viscosity, can remove the residue on the surface of the teeth, so often chewing gum can clean the teeth, fresh breath, prevent caries, help to improve oral health, and can promote facial blood circulation so that facial muscles can be exercised, the teeth and maxillofacial development has a role. Japanese scientists have found that chewing gum can also temporarily improve memory. In addition, chewing gum can also relieve earache when flying.
Chewing gum has many benefits, but it is not suitable for eating more, so pay attention to the appropriate stop.
