He bulk, as a result of rupture of hydrogen bonds between water molecules and polar functional groups. Around the the 8c), this hydrogen bonds in between water molecules and polar functional groups. On DSC curve (Figurerupture ofprocess corresponds to a distinct endothermic peak. The price the DSC curve (Figure 8c), growing temperature a to 280.74 and after that of fat reduction for xanthan increases withthis procedure corresponds toupdistinct endothermic peak. The price of fat loss for xanthan increases with rising temperature as much as 280.74 C and decreases. Thus, the key degradation of xanthan occurs in one particular step. Inside the range of the then decreases. Therefore, the key degradation of xanthan occurs in one particular step.

The endothermic effect around the DSC curve in the indicated interval is flatter and not as pronounced.Foods 2021, 10,11 of021, ten, x FOR PEER REVIEWFor sulfated xanthan, the initial stage of heating (as much as 180 C) is characterized by a less intense weight-loss (-7.7 ), when compared with the original xanthan. The endothermic effect on the DSC curve with the indicated interval is flatter and not as pronounced. The principle decomposition of xanthan sulfate, in contrast VBIT-4 supplier towards the original xanthan, occurs in two stages. The DTG curve has two pronounced peaks, with maxima at 226 and 286 C. The initial stage is probably related together with the decomposition of sulfo groups (weight reduction 18.eight ). Throughout the second stage of decomposition (as much as 300 C), xanthan “loses” 64 . On the DSC curve, the decomposition of sulfo groups corresponds to a sharp and rather intense exothermic peak, using a maximum at 226 C, which, with a rise inside the heating temperature, passes into the endothermic zone. The endothermic impact in this area is probably related with the melting in the substance together with the simultaneous decomposition of the structure of xanthan sulfate; the latter statement is confirmed by the slope from the TG curve in this interval. Further 12 of 16 heating of your sample to 600 C results in aromatization from the structure using the formation of a carbonized residue (fat reduction 79 ). 3.7. Atomic Force Microscopy 3.7.
