Things are really getting cheesy at BUCHI.

When prodded, I suppose many at BUCHI would agree that some of the cheesiest members of the team belong to the NIR group.

Maybe that’s something to be proud of!

More cheese, please!

Cheese is delicious, after all. With a global market of around $100 Billion USD, I think there is a general agreement on the matter.

There are many ways to consume cheese, of course. Processed cheese products like fondue have their place on the cheese continuum, particular around special events like graduation parties and weddings that seem to dominate our summer calendars.

Manufacturing processed cheese products like fondue is a complex task, with special emphasis on key quality parameters like total solids and fat content.

These products are typically produced by blending one or more shredded natural cheeses with additional ingredients, such as: emulsifying salts, condiments, flavors and other goodies. This mixture is then heated and sheared until a homogeneous molten mass is obtained which can be poured into heart- or graduation-capped shaped molds or other shapes for future devouring.

In order to consistently deliver the same great-tasting product, real-time control of key quality attributes is a must. Monitoring total solids content, fat, salt, pH, homogeneity and more during a blend can allow for real-time process adjustments to meet all of the quality targets and avoid having to rework a batch. The end result: tasty cheese products (read: make money) and improved manufacturing efficiency (read: save money).

While traditional laboratory methods exist for determining the quality parameters, issues with representative sampling and the method collection times are rate-limiting.

You can also visit our NIR-Online Solutions page to learn more.

If cheese quality is on your mind, but an on-line solution isn’t a good fit, BUCHI also has milk & dairy solutions for our off-line and at-line NIR. You can use our NIR Applications Finder on-line tool to configure the perfect NIR solution for you. Choose your industry and products, then get a full listing of available pre-calibrated applications, plus a quote.

Among our pre-calibrated parameters, you’ll find: dry matter, moisture, fat, protein, lactose, fatty acids, total sugar, ash and more.

Use our new NIR Application Finder to get the latest in Pre-Calibrated Solutions for your industry.

Interested in an application that isn’t listed? Fear not! We have a team of Application Scientists at the ready. Reach them using our Application Support Request Form .

If you’re looking for the full gamut of our published cheese & dairy applications, check out the BUCHI Application Finder. You’ll find methods related to:

  • Extraction
  • Spray Drying
  • Kjeldahl for protein determination
  • Near-infrared spectroscopy

Stay cheesy, my friends!

Evolution of BUCHI NIR

February 12 was Darwin Day. Darwin, of course, was known for his theories of evolution. While his theories continue to be hotly debated 137 years after his passing, none could argue that products and companies must evolve in some capacity to keep pace with, and meet the demands of customers-at-large.

Charles-Darwin-1880-631

Borrowing the words of Spanish soccer player Gerard Pique, “Evolution is all about looking forward.” The BUCHI NIR portfolio shows evidence of evolution in that sense. 

The BUCHI NIR “big bang” occurred in 1999 with the acquisition of Buhler NIR, with incremental steps leading up to the dramatic upgrade to the NIRFlex series, and so far culminating with the N-500 FT-NIR product.

The NIRFlex bench-top instrumentation was designed to meet consumer demands in both R&D and routine testing labs for true flexibility and high performance. Hot-swap modules accommodate nearly any sample type (i.e. solid, liquid, semi-solid or slurry), while the Fourier-transform (FT) technology provides exceptional precision. A novel single-beam FT design further propels instrument performance, stability and robustness, while hardware and software components continue to meet even the demands of the  pharmaceutical regulatory agencies.

NIRMaster_NIRMaster_ProNext, the NIRMaster was added to the portfolio specifically to serve the demands of the food and feed industries, bringing with it IP-54 and IP-65 ingress protection and features designed to ensure food safety. This revolutionary design was the first to marry the accuracy of FT-NIR with a robust and hygienic standalone at-line design suited for the production floor.

NIR-Online

In 2005, the BUCHI portfolio expanded with the acquisition of German on-line sensor manufacturer NIR-Online, just a modest train ride away from company headquarters in Flawil, Switzerland. With this acquisition, BUCHI was finally able to offer a true in- and on-line NIR solution for process control. Since its introduction, the NIR-Online product has further evolved, expanding capabilities to include multiplexing, and continuing to meet requirements for workplace safety, including explosion-proof options for hazardous environments.

In late 2018, the BUCHI NIR portfolio saw its next evolution: the ProxiMate. This at-line workhorse took the speed and agility of the NIR-Online solution at-line, creating an affordable option for the typical food and feed industry customer without compromise in quality or performance.

ProxiMate_masterProxiMate offers 3 main benefits for food and feed industry users: applicative fit, extreme robustness and simple operation.

  • BUCHI application chemists have developed many ready-to-use pre-calibrations typically required by the food and feed industries, enabling accurate results with minimal effort and by users of any ability level

Of course, the idea of the “survival of the fittest” comes to mind on Darwin Day. It seems that the more recent of our evolutionary steps in the NIR product portfolio has been hyper-focused on robustness–survival in the dirtiest, harshest, or most hazardous environments.
