A green analytical method for rapid determination of pectin degree of esterification using micro sequential injection lab-on-valve system

- A novel method for determination pectin DE (%) using μSI-LOV system.
- Optimisation of μSI-LOV system parameters using response surface methodology.
- Calibration curve for non-esterified GalA content of 0.08-0.34% (w/v), R2 = 0.995.
- Comparison of DE (%) of pectin samples obtained by proposed and manual method.
- Very good precision and consumption of low volumes of sample and chemical reagents.
