For sucrose refining, shell-shell activated carbon can be used, which can be used for decolorization before sucrose pulp is crystallized into white granulated sugar. On the one hand, the shell activated carbon can adsorb plant pigments from sugar cane, and can also absorb the color produced by the production process (such as melanoid and caramel). Powdered activated carbon can be used for large-scale production and then thermally regenerated. The application of granular activated carbon is flexible and can be used to treat sucrose raw materials due to the quality of the different origins and the scouring process must be adjusted for this purpose.
Natural glycerin
The shell activated carbon is used to purify natural glycerin, which is derived from high pressure cracking and vinegar transfer of edible oils and fats or biodiesel. Refined glycerin is used as a food additive to prevent food from cracking or to prevent food phase changes due to dry cracking. This property improves the softness of the food and the chewiness of the confectionery. Powdered activated carbon is used to remove organic impurities such as colored substances and some substances that cause isoindoles from glycerin.
Biochemical food
The shell activated carbon and coconut shell activated carbon can adsorb syrup pigments. The sources of these pigments are citric acid, lactic acid and other biochemical foods. Powdered activated carbon can also be used to increase biochemical conversion efficiency during fermentation. For the final product purification of lactate and gluconate, ultra-high purity activated carbon products meet the most stringent purification requirements.
