Abstract:
The proximate composition and functional groups of dried red chillies were affected by a number of light-based techniques, including Ultraviolet C (UV C) radiation, blue light emitting diode (LED), and atmospheric plasma. The proximate composition, Vitamin C content, and functional group analysis of the control and treated samples were performed using Fourier transform infrared (FTIR) spectroscopy. The results demonstrated that these techniques had a significant impact on the proximate composition and vitamin C content when compared to the control sample. With the exception of plasma, the vitamin C content of chilli increased significantly and functional groups were relatively maintained across all treatments when compared to the control sample. These light-based techniques can be preferred over other nonthermal techniques to preserve the nutrient compositions and functional properties of chilli.
