Infrared absorption. Sugars also have known infrared absorption spectra and this has made it possible to develop instruments for measuring sugar concentration using mid-infrared (MIR), non-dispersive infrared (NDIR), and Fourier transform infrared (FT-IR) techniques.
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. Both methods will give the same result if pure sucrose/HFCS content of a solution is measured. Brix Hydrometers are widely used for measurement of Brix.
In this science fair project, you will investigate the concentration of glucose in common fruits and juices. In order to measure the glucose concentration, you will use glucose test strips. These strips were developed to help people with diabetes maintain a healthy level of blood glucose.
The Brix scale is used to measure sugar content in substances such as soft drinks, fruit juices and tomato concentrates, as well as products such as cutting oil, which are very often far away from pure sucrose/water solutions.
In this science fair project, you will learn how to measure the concentration of sugar dissolved in a liquid by using a laser pointer, a hollow prism, and some physics. You will discover how refraction, or the bending of light, is the key to measuring the sugar content of a liquid with a laser pointer.
Since sugar concentration has a linear relationship with SG and density, Brix can be measured via any of these two quantities. The most popular instrument for Brix measurement is either refractometer or a hydrometer, where a refractometer is an optical device, and a hydrometer is a glass device used to measure the specific gravity [ 4 , 5 , 8 ].
