| titleOfInvention | A kind of preparation technology of oligosaccharide maltose syrup with high maltotetraose content |
| abstract | The invention discloses a process for preparing maltose oligosaccharide syrup with high content of maltotetraose, which includes: adding water to starch to make starch slurry, adjusting the pH of the starch slurry to 5.8-6.0; adding high temperature resistant α-amylase to the starch slurry. The starch slurry is prepared by one-time spray liquefaction, laminar flow tank insulation, and second-time spray liquefaction to obtain a liquefied liquid; when the liquefied liquid is rapidly cooled to 55-65 ° C, pullulanase and maltotetraase are added successively to carry out saccharification reaction After 5-18 hours of saccharification reaction, a reaction solution is obtained; the reaction solution is subjected to activated carbon decolorization, ion exchange and concentration to obtain the maltose oligosaccharide of the present invention. In the present invention, a flash heat exchanger is used to rapidly cool down to the saccharification temperature after the liquefaction is completed, so as to avoid the problems of starch aging and retrogradation during the cooling process, and a two-step enzymatic addition method of adding pullulanase and then adding maltotetrasidase is used to carry out the process. Saccharification, improving the conversion rate of maltotetraose, simplifying the technological process, and preparing the oligosaccharide syrup with the content of maltotetraose ≥65%. |
