Comparison of Si-GA-PLS and Si-CARS-PLS build algorithms for quantitation of total polyphenols in black tea using the spectral analytical system.

The build model's prediction ability was amended in the order of PLS<Si-PLS<CARS-PLS when full spectroscopic data was used and Si-PLS<Si-GA-PLS<Si-CARS-PLS when interval selection was performed with Si-PLS model. Finally, the developed method was successfully used to quantify total polyphenols in tea. This article is protected by copyright. All rights reserved.
