Dairy analyser double-act hands new powers to cheesemakers

Cheese table
By Richard Mills
The analytical landscape has changed for producers wanting quick, accurate tests on both liquid and solid samples during the cheese making process.

The new DairyScan™ is a handy new analyser that measures moisture and fat in cheese samples. Another recently released analyser, the MilkoScan™ Mars is a similar solution, but aimed at liquid milk analysis. Together they provide an alternative to either time-consuming traditional analysis with methods such as the Gerber method or rapid tests with solutions that seek to cover both liquid and solid samples with a single analytical technology. 

 

 

MilkoScan Mars and DairyScan

 

Why not one universal solution
While having one instrument to cover both liquids and solids might sound ideal, in reality it is a compromise in terms of accuracy. It is all about different forms of infrared analysis and what they are best at. 

Near Infrared (NIR) is the best technology for solid samples, in particular the form of NIR called near infrared transmission employed in the DairyScan, allows the light to penetrate the sample for a representative measurement.

Fourier Transform Infrared (FTIR) combines high sensitivity with a full spectrum making it particularly useful for liquid milk samples. As well as measuring parameters such as fat and protein with high accuracy, FTIR technology can be used to screen incoming raw milk samples for adulteration.

For more parameters and more sample types
The two technologies are well proven in two other FOSS solutions that have served the dairy industry for decades, the MilkoScan FT1 and FoodScan for dairy

The MilkoScan Mars and DairyScan provide slimmed down versions of both solutions, offering the same reliability and speed, but with more limited range. In the case of the MilkoScan FT1, it can give a wider range of measurements for liquid milk and also handle viscous sample types such as yoghurt. The FoodScan handles the same type of solid samples, but tests more parameters. Both instruments are larger than the DairyScan and MilkoScan Mars and are, inevitably, in a different price  bracket.
