Degrees Brix is the unit used to determine
sugar content in a solution. |
Degrees Brix is a measurement unit to determine sugar content, typically in the
food and beverage industry using a
refractometer. Brix measurements allow precise quality control for sugar levels in different beverages, with one degree Brix equating to 1 gram of sucrose in 100 grams of solution. While sucrose is the primary element measured by the Brix reading, it is important to understand how other ingredients affect the Brix reading. The Brix reading can relatively calculate the amount of sweetener in a certain product in addition to exactly calculating the previously mentioned sucrose level.
Sucrose and other sweeteners allow for members of the food and beverage industry to create unique recipes for their products. However, a sucrose solution dissolved in water will return different Brix values than a soda because other elements in the process impact the Brix reading. To account for these shifting variables, a Brix value can be measured through either density or refractive index. Specific control parameters need to be established prior to measuring these solutions with refractometers, thus causing the term “Refractive Brix” to be used when comparing samples against results obtained via different calculation methods. Along with the numerical sugar concentration of a particular product, a product’s sugar concentration correlates to the product’s sweetness, giving controllers the ability to ensure repeatability in their process.
Alongside Brix’s main functionality as an indicator of sucrose, high fructose corn syrup (HFCS) has become popular in the food and beverage industry as a replacement for sucrose. Recently, the amount of HFCS in a certain product has also been expressed as Brix, allowing for the Brix degree measurement to expand past its original purpose. Digital refractometers have become increasingly popular in measuring Brix degrees and also the percentage of HFCS in a certain product. These dual measurement possibilities allow operators to compare the content of a certain substance across multiple variables of sweetness. Additionally, the availability of these measurements in a certain process via the same measurement device allows for simplification of the measurement process. Hydrometers are another method used to measure Brix, although, as opposed to refractometers, variations in operator control may cause the results of a hydrometer test to be different. Both Brix and HFCS allow for food and beverage controllers to maintain cost and quality control, both in determining how much sucrose should be used in the process and to ensure each individual product meets quality standards.
