Xinhua News Network News Students from Du Jingwen, Kang Jie, and Wang Changqian of the School of Food Science and Engineering at Nanjing University of Finance and Economics have used their brains. Under the guidance of teacher Tang Pei'an, after repeated experiments, he developed a "green chewing gum" and won the first prize at the Nanjing University Students Food Technology Forum.
According to reports, the main ingredients of chewing gum are sugar powder, syrup and gum base. Because the gum base of traditional chewing gum is rubber and calcium carbonate, it has strong adhesiveness. Du Qianwen told reporters that the formulas of biodegradable gum bases they used included zein, polyester resin compounds, ester gums, calcium carbonate, glycerol monostearate, etc. This formula can make chewing gum base suitable The viscoelasticity and plasticity are not brittle in the winter and soft in the summer, so that the chewing ability, film forming property, and odor-susceptibility of the chewing gum are almost the same as those of the conventional chewing gum.
Kang Jie introduced that they are using the cornstarch factory's waste - corn yellow powder to process chewing gum base, so the cost will not be very high. "Maize yellow powder has a rough taste, poor water solubility, and lack of lysine and tryptophan. It is often used as a feed. Our approach is to turn waste into treasure and use organic solvent extraction or ultrasonic extraction methods to extract corn alcohol from it. Lysin was processed into chewing gum bases after plasticization, kneading, homogenization, emulsification, and molding.†In addition to the degradation of the gum base, the students also added spirulina, raffinose and other ingredients to the chewing gum. Make chewing gum has a health function.
Du Qianwen said that although the chewing gum they developed could be automatically degraded, they still hoped everyone would pay attention to public health and consciously throw the chewing gum residue in the trash. (Correspondent Li Rongguo reporter Wang Jinghui)
