MAUNFACTURING METHOD OF HIGH PURITY CHITOSAN AND CHITOSANOLIGOSACCARID

摘要

PURPOSE: a kind of manufacturing method purifying cleanser utilize chitosan and chitin polymer with for improve water purification by destroy specific microorganism to Gram-negative bacteria and gram-positive bacteria (molecular weight) according to and enhance water purification by combining, and absorb the chitosan of toxicant and heavy metal by space structure. ;CONSTITUTION: it is a kind of purify cleanser manufacturing method include the following steps. The chitosan of step 2.0 ~ 7.0% is dissolved in the acetic acid solution of its viscosity to 0.5 ~ 5.0% for having the distillation and 10 ~ 23 centipoises more than 90% degree; Increase by 0.5 ~ 5.5 units/kg citizen to reaction 10 ~ 16 3 hours, in pH 4.0 ~ 6.5,30 ~ 55& deg almost without the molecular weight less than 5000 with production low molecule chitosan oligosaccharide; C. And the manufacturing method for purifying cleanser includes the following steps. The chitosan of step 1.0 ~ 3.0% be dissolved in its viscosity for having the distillation and 200 ~ 400 centipoises more than 80% degree into 0.5 ~ 5.0% acetic acid solution and generation step almost without polymer shell oligosaccharide molecular amount than 300,000 increases by 0.5~5.The citizen of 5 units/grams are to reaction 8 ~ 12hours pH 4.0~6.5 and 30 ~ 55& deg; C. ;The 2013 of copyright KIPO submissions;[Reference numerals] (AA) ammonium; (BB) ammonium sulfate; (CC) supernatant; (double) centrifuge; (EE) ultra filtration
