The invention belongs to the field of bioengineering, and in particular relates to the application of 5-hydroxy-2 pyridine carbinol isomers as chitooligosaccharide browning markers. The applicant's analysis found that there is an intermediate product in the process of the Maillard reaction (MR) of LMWC, which is an isomer of 5-hydroxy-2 pyridine methanol (5-H-2PMIS), which persists throughout the MR reaction. , so this substance can be used as a browning marker of LMWC. By monitoring the content of 5‑H‑2 PMIS and pigment OD420, it was found that moisture content, pH value, temperature, CO2, and inhibitors had a great influence on MR. The invention determines the important intermediate substances in the Maillard reaction of chito-oligosaccharide and fills the blank. |
