During drying, fermentation occurs, leading to the creation of hydroperoxides and causing a decrease intensity of the O-H stretching peak at 3444 cm−1 [37]. Using a regulated fermentation process (DP technique) reduced the production of alcohols, thereby impacting O-H stretching 3280 cm−1...
The Y-axis of the tendency chart represents the percentage of the related composition, while the X-axis shows the development time of the pupae. The table under the figure shows the parameters of the equation. The FTIR spectra were also selected from the OPLS-DA and PLS models according to...
