Technical Documentation on Bris (Sugar Content) in Juice Using Near Infrared Analyzer (NIR)

Simultaneous measurement of sugar content (Brix), glucose, fructose, and sucrose in fruit juice using near-infrared analyzer.

【Near Infrared Analyzer Technical Data 24 Food and Beverages】 When considering root juice as a product, the sugar content in the product is a very important parameter because it is a sweet beverage. Among these, the contents of fructose, glucose, and sucrose are considered very important sugars for quality control. Traditionally, to measure these sugars in fruit juice through laboratory analysis, liquid chromatography is used along with refractive index measurement. When there are multiple analytical methods like this, each analysis requires time and expertise, as well as the need for different analytical instruments. Near Infrared Spectroscopy (NIRS) is an analytical technique that can simultaneously measure glucose, fructose, sucrose, and Brix in fruit juice in under one minute. Furthermore, it does not require chemical reagents, and no sample pretreatment is necessary.
