Hydrolysis conditions
WebIf direct hydrolysis with water is kinetically too slow, base can be added to catalyse the reaction. This generates a carboxylate salt which can be isolated or acidified to obtain the free acid. Where water sensitivity or solubility is an issue, a hydroxide soluble in organic solvent can be employed, or a basic phase transfer catalyst. Weba Conditions: 22 hours under reduced pressure in twice distilled HCl at 110”. b Calculations are based on the content of 8 half-cystine resi- dues per mole of protein as 100% (2,3). c Cysteic acid value was taken as 100%. d Not determined. 8 Hydrolyzed for 72.5 hours.

WebThe hydrolysis conditions have been widely adopted due to easy handling and high repeatability. However, this method still has the obvious disadvantages of low SNC yield and long duration of the acid hydrolysis process. WebAfter optimizing the hydrolysis conditions, the most suitable concentration of H2SO4 (2%), hydrolysis temperature (120 °C), hydrolysis time (100min) and solid/liquid ratio (1:10) were obtained. The yield of monosaccharides reached 258 mg/g DDGS and 15.88 g/L glucose, 7.53 g/L xylose and 2.35 g/L arabinose were obtained in unprocessed …
