Infrared spectroscopy - alternative instrumental tool for control of bioethanol production.

Abstract

We investigated the possibility of application of FT-IR (Fourier transformed infrared spectroscopy) and FT-NIR (Fourier transformed near infrared spectroscopy) for analysis of mash parameters. Main parameters of mash were ethyl-alcohol, calcium lactate, glucose, fructose and dry matter amount (Brix degrees). Infrared spectropy was determined like a quick and relatively accurate method for control of ethyl-alcohol manufacturing process.We investigated the possibility of application of FT-IR (Fourier transformed infrared spectroscopy) and FT-NIR (Fourier transformed near infrared spectroscopy) for analysis of mash parameters.
