From the figure it can be observed that, over the course of 30 min, no degradation is detected of the capsaicinoids up to a temperature of 125 ◦C.
The degradation of the capsaicinoids begins to be seen at 150 ◦C; in fact, there are three compounds that present a significant difference from the reference, and this degradation becomes more marked as the temperature is increased. At 200 ◦C a very striking degradation of all the capsaicinoids present in the extract is observed.
Based on these findings, the extraction method developed will take place at 125 ◦C, to ensure that there will be no degradation of the compounds of interest
