Brix Corrections for Citric Acid and Temperature
Brix Corrections for Citric Acid and Temperature
The total soluble solids (TSS) contents of fruit juices and other food products is conveniently determined by a refractometer and expressed in °Brix (), which stands for the percent weight of a sucrose solution having the same refractive index at 20 °C. Since citrus juices have a considerable amount of citric acid and the 20 °C temperature is not always maintained, the refractometer's reading needs to be corrected for acidity and temperature following standard tables. This Demonstration calculates the correction for either or both, with the formulas used to create these tables.
