Why is chewing gum chewy?
In many ways, chewing gum is a perfect example of modern chemistry at work. We see miracles of polymers in our everyday life,from plastic bottles to innovative packaging designs. Have you ever considered all the wonderful science behind such a fun food product like chewing gum? For many years,chicle was the main ingredient in gum base. However,manufacturers eventually began looking for a less expensive alternative to this natural product obtained from the latex of some trees. For most of the present manufacturers,gum base is created using synthetic rubber that has proven to be cheaper to produce,easier to manufacture and even more effective as a base for chewing gum products. One of these is styrene butadiene rubber (SBR). It is a copolymer of styrene and butadiene used for many purposes such as car tires. Other rubber bases used are polyethylene and polyvinyl acetate. While gum base makes chewing gum sticky and chewy,all the other substances we see in gum are what make...
