I was hoping someone can advise me with the following:
One of the products we manufacture is a dairy blend concentrate (1+7). We currently have a situation where the Brix of our mixture differs between batches of the same flavour. For example, if producing peach flavour, the Brix will be within specification (say 5.0) when the final volume (say 5800 L) has been reached. However every now and again the brix of that exact same product, at the exact same final volume (5800L) is suddenly 5.3. Why would this happen?
I know components in the water and citric acid etc has an influence on the Brix, however the ingredients in the different mixtures are exactly the same. We use Reverse Osmosis water. We also make use of the same, digital refractometer to measure the brix.
If anyone has some advise, I would appreciate it!
Thank you :)
