Abstract

17/06/2022(OCR) Carboxymethyl cellulose production process (Carboxymethylcellulose) from bagasse consists of steps that have specific characteristics, namely the step of preparing cellulose pulp from bagasse and the step of producing carboxymethylcellulose from cellulose pulp. Which from the invented process is a process for producing biopolymer carboxymethyl cellulose that can produce high amounts of carboxymethyl cellulose. Reduce complicated steps Reduce the use of chemicals and reduce the extraction time To further expand the use of carboxymethyl cellulose in the food industry, such as as a stabilizer, thickener, moisture control, ingredient in edible films, etc. In addition to the food industry, carboxymethyl cellulose can also be used in the production of paper, leather, various cosmeceuticals and medical material products. Production process of carboxymethyl cellulose (Carboxymethylcellulose) from bagasse consists of steps that have specific characteristics, namely the preparation of cellulose pulp from bagasse and the production of carboxymethylcellulose. C-methylcellulose from cellulose pulp Which from the process that was invented is the production process of biopolymer car. Boxymethyl cellulose that can provide high amounts of carboxymethyl cellulose. Reduce complicated steps, reduce the use of chemicals, and reduce the extraction time.
