FT-IR-based fingerprint combined with unsupervised chemometric analysis revealed particle sizes and aqueous-ethanol ratio alter the chemical composition and nutraceutical value of .

This study reported the effects of particle size of dry powder and the optimum solvent extraction on the nutraceutical value of carrot by observing its FT-IR fingerprint, TPC, TFC, and antioxidant activity. The dried-powdered carrot was ultrasound-assisted extracted using EtOH, water, and EtOH-water. The TFC, TPC, and antioxidant activity were analysed by a colorimetric method using a spectrophotometry UV-Vis.
