US 11,879,163 B2 · Methods for monitoring and controlling contaminants in food processing systems

Abstract

A method for determining the lignin or lignin by-product content of a process stream includes measuring the fluorescence parameter of a fluorescence spectra of the process stream, comparing the measured fluorescence parameter with predetermined a fluorescence parameter of lignin or lignin by-product reference samples, determining the amount of lignin or lignin by-product based on the comparison with the reference samples. Lignin or lignin by-products can then be removed from a process stream by adding a sufficient amount of a compound suitable for precipitating the lignin or lignin by-product to the process stream, and removing the precipitated lignin or lignin by-product from the process stream.

Dependent claims

A method or controlling an amount of an anionic contaminant in a stream of a sugar processing system, the method comprising:

determining an amount of the anionic contaminant in the stream using a fluorescence parameter of the anionic contaminant, the anionic contaminant selected from at least one of the group consisting of lignin, a lignin by-product, tannin, and a tannin by-product;
and
controlling an amount of the anionic contaminant in the stream based on the determined amount of the anionic contaminant in the stream.
