How do you measure sugar in orange juice?

To measure sugar in Orange Juice, you can use a refractometer, which measures the refractive index of the juice to estimate its sugar content, typically reported as Brix (degrees Brix). Alternatively, you can use a hydrometer, measuring the specific gravity of the juice, which can also indicate sugar levels. For more accurate results, laboratory methods like high-performance liquid chromatography (HPLC) can be employed to quantify specific sugar types.
