Introduction

High fructose corn syrup (HFCS) is one of several products-along with glucose, dextrose, corn starch, ethanol, and other products-derived from the wet milling of corn. U.S. corn refiners produce high fructose corn syrup by first converting corn starch to a syrup that is nearly all dextrose. Enzymes isomerize the dextrose to produce a 42-percent fructose syrup called HFCS-42. By passing HFCS-42 through an ion-exchange column that retains fructose, corn refiners draw off 90-percent HFCS and blend it with HFCS-42 to make a third syrup, HFCS-55.

Overview

Imerys has a range of DE and perlite grades for filtering product at different steps of production. The grades offer a good balance of permeability and clarity, high flow rates and low solids penetration. In addition, our EuroPerl HD and Harborlite S perlite filter aid series are optimized for easy and fast pre-coating, reduced unit consumption and high flow rates in Rotovac applications.
