Using the Kjeldahl method for sulfur dioxide determination in alcoholic beverages A patented BUCHI SO2 Method for the determination of Total SO2 in beer to satisfy regulations by the European Union (maximal permitted level of total SO2 of 20 mg/L), or the FDA (25 mg/L). Levels of SO2 higher than 10 mg/L must be labelled. The process can be used to analyze other beverages, such as wine. The same equipment can also be used for food analysis and protein determination via nitrogen determination in liquid samples such as milk.

Dr. Fabiana Quaglia, Associate Professor of Pharmaceutical Technology at the Faculty of Pharmacy–University of Napoli Federico II, Italy discusses how reliability and smart features of the rotary evaporator, Rotavapor® R-300, let her easily evaporate solvents in particle production for cancer and cystic fibrosis drug development and formulation. Diletta Esposito, one of her PhD students, shares her experience of using the Rotavapor® in her research on natural product delivery through particle technology. Unique features such as a centralized interface, various condensers, Combi-clip system for flask attachment, foam detector sensors, automated distillations and remote monitoring of process parameters enable the scientists to fully focus on their research while fully trusting the quality control of their final products. The convenient features of the system also allow Dr. Quaglia to let her students use the equipment with minimal training.

Mr. Robert Paxton, Mix Plant Manager at Krispy Kreme Dougnuts discusses how NIRMaster and NIR-Online contribute to fast quality control of incoming goods by providing reliable measurements of important parameters, such as moisture, protein and fat. Mr. Paxton emphasizes that the functionality and ease-of-use of the NIR units are great for reducing the amount of work for lab techs while simultaneously delivering the consistent results needed for a smooth production process. 

How Krispy Kreme uses NIR to add speed and reliability to quality control at the production line 

Reference methods in food processing generate results with certified accuracy and dependability. During food manufacturing, samples are analyzed at various production points to ensure full conformance to quality standards. Fat extraction is a reference method for assessment of food and feed samples. The process is ideal for control of ingredients, mixtures, intermediates and final products. This video summarizes three of the most commonly used methods for fat extraction in food processing analytics. The processes of Soxhlet extraction, hot extraction (Randall) and continuous economic extraction (Twisselmann) are described graphically. Users can gain a clear idea of the differences between the approaches and decide if a particular method is suitable for their sample. The video also showcases the revolutionary FatExtractor E-500 for quick extraction of total or crude fat from food and feed samples. The fat extraction system offers convenient combination of several extraction methods, including Soxhlet, hot extraction and Twisselmann in one unit. The fully automated fat extractor can process up to six samples in parallel for faster processing times. The system offers performance that is in full accordance with official regulations: ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ Some of the benefits of the FatExtractor include: 🔹 Easy switch between Soxhlet, hot extraction and Twisselmann by simple interchange of glass assembly 🔹 Highest extraction efficiency thanks to individual level sensors 🔹 Flexible sample sizes 🔹 Cost-efficient ability to collect and reuse solvent 🔹 Maximal user and environmental safety thanks to innovative flange z-seal system that guarantees minimal solvent emission 🔹 Intuitive operation for users of any skill level with easy setup of an automated extraction or use of pre-set methods
