Fast Casein Test

Hi,

Reasoning that rennet will set mainly casein and that the whey proteins will be free to run away with the whey(hey, it rhymes!) I have thought of using this to determine the casein content of milk.
This with a cheap little milk analyser like an Ekomilk. I would test the milk protein and then set the milk with rennet and then put the resulting whey through the Ekomilk. Subtracting the 2 figures from each other would then theoretically give the casein content of the milk.
Well, this sounds logical to me, but that does not say a lot and I don’t know how that would compare to a Kjeldahl determination, which would be the official way of doing it.
May be a project for a rainy day. Any comments?

See ya!

Milkoscan 133B

Hi, Milkfans

Have some time to write, because my FOSS Milkoscan 133b has a problem with the “filter wheel not running OK” at the correct speed. For you other lab techies out there the procedure to check for this is to turn the key to horizontal and to type in Program 9824 from the Standby Menu. You should get a reading of 14400 if everything is alright. Slight variations from 14400 is OK, but preferably it should be constant.
When finished testing turn the key back to vertical and press the RESET button on the back of the machine.

Till next time,

Welcome!

Hi, Milkfans

Thanks for visiting my dairy-friendly website!
We will discuss industry and consumers issues.
Here in South Africa I work at the Elsenburg Dairy Lab, just outside of Stellenbosch, in the Western Cape. That’s near Cape Town for all you international visitors.
Well to some good fun and lots of valuable info in the future!

Bye for now.
