  • Why are polyacrylamide based anionic flocculants used in sugar production?
  • In sugar production, polyacrylamide-based anionic flocculants are added for juice treatment, the main objective being to remove impurities that affect the quality of the sugar. However, if they remain in the final product, those polymers can present carcinogenic and neurotoxic actions besides contaminating the soils where the waste is discharged.
  • Can natural flocculants replace polyacrylamide in sugar cane juice purification?
  • To overcome this problem, the present study proposes, for the first time, natural flocculants based on cellulose obtained from sugarcane bagasse (residue from sugarcane processing) as substitutes for the flocculants based on polyacrylamide, normally used in sugar cane juice purification.
  • Is polyacrylamide a comonomer?
  • Polyacrylamide (PAM) is the basis for most commercial polymeric flocculants mentioned in the literature (anionic, cationic, or non-ionic); this polymer is also modifiable with combinations of comonomers.
  • Can syrup clarification be used in conjunction with syrup sulfitation?
  • In one case where syrup clarification was used in conjunction with syrup sulfitation, the colour of the product sugar was reduced from about 150 IU to below 100 IU. In another case, the colour of the sugar was reduced from 150 IU down to 120 IU by replacing the syrup sulfitation process with syrup clarification.
