Introduction There are a lot of different sugars, e.g. sucrose, malt sugar, glucose, HFCS. Strictly speaking of Brix,only the pure sucrose content in a solution is meant. But often as well, the High Fructose Corn Syrup (HFCS) is measured and expressed in Brix ˚. This sugar concentration can be measured with density meters and refractometers. Both instruments are capable to convert the measured experimental data automatically into Brix degrees or HFCS. What is Brix ? Brix is the measurement in percentage by weight of sucrose in pure water solution. This designation of Brix degrees is only valid for pure sucrose solutions. Pure sucrose is extracted from sugar-cane or sugar-beet. What is HFCS ? High Fructose Corn Syrup (HFCS) is a liquid sweetener that is extracted from cornstarch containing mainly Fructose and D-Glucose. HFCS is used to replace sucrose in the beverage and food industries. HFCS is available in three different fructose levels HFCS 42%, 55% and 90% weight percent and is mainly used in the USA. Two methods to measure Brix and HFCS It is possible to measure the Brix and HFCS content either with a density meter or a refractometer
