| titleOfInvention | Optimized method for purifying starch used as glucose polymer raw material for peritoneal dialysis |
| abstract | The present invention relates to a process for purifying starch used as a raw material for the preparation of glucose polymers intended for peritoneal dialysis, comprising the following steps: -preparing waxy corn starch; -placing the waxy starch in suspension at a concentration of between 20% and 40% dry matter in process water having a pH of between about 5 and about 6, in particular about 5.5; -treating the starch suspension with a peroxyacetic acid solution having a concentration equal to or between 100ppm and 500ppm, preferably 300 ppm; -dehydrating the starch and then dissolving it in demineralized water adjusted to a pH between about 5 and about 6, in particular about 5.5, and in a concentration of between 20% and 40% dry matter; -increasing the temperature to about 107 ℃ and then adding the alpha-amylase for 15 minutes; -optionally, treatment with an enzyme preparation having detergent and clarification properties; -filtering the suspension over a bed of diatoms; -treatment with activated carbon having very high adsorption capacity, pharmaceutical quality and "microporous" porosity; -treatment with a second activated carbon having a porosity of "mesopores"; -optionally, passing through a macroporous adsorbent polymeric resin having a porosity greater than 100 angstroms; -optionally, performing a continuous 5000Da ultrafiltration; safe filtration through a sterile filter with a porosity of 0.22 μm. |
