Food & Beverage: Caffeine concentration

Analytical monitors for flow chemistry processes can provide precise, accurate, and timely measurements to ensure that products or excipients are properly quantified and are being produced with maximum efficiency. However, current spectroscopic tools are limited to bulk analysis and are a bottleneck in many applications. Tornado Spectral Systems HyperFlux™ PRO Plus puts Raman into the forefront of monitoring and controlling these highly dynamic processes.

The results in this app note are striking in their demonstration of a model developed in-line yielding low detection limits, <15 ppm. Combined with SpectralSoft™ 3.0, Tornado’s HyperFlux™ PRO Plus is the ideal continuous process Raman analyzer that delivers unprecedented measurement precision and actionable data for applications that demand specificity, high sensitivity.

Milk and Dairy Products Analysis

Raman analyzers have proven to be a useful tool for the analysis of milk and dairy products. Milk products, being consumable food stuffs, are subject to rigorous regulation throughout the world both economically and nutritionally and require adherence to quality standards for production, industrialization, and commercialization. Raman Spectroscopy has been investigated as a method to analyze and quantify several key attributes.

Recent work with Tornado Raman analyzer has been able to quantify fat and protein concentration, thus being able to identify skim milk from whole milk and 2%. Raman spectroscopy has also been used to successfully determine proper pasteurization, classify adulterants, and even determine the animal species from where the milk was produced. Analyses can also be performed for a purpose of rapid assessment of lactose content in bovine milk, lactose-free milk, mixtures of bovine milk and lactose-free milk, and bovine milk with additions of lactose. With Tornado Process Raman analyzers , milk production analysis can be employed in-line in a sterile manner that requires no grab samples and offline analysis.
