Method, limits and sources
What this does not do. It does not set your target: the minimum composition of a named milk product is set by the food standards that apply to it, and those change, so confirm the current requirement. It works on weights; if you measure in litres, convert with the density of each stream. It assumes the figures you enter are the true composition of each stream.
Method
- Two streams: the Pearson square. Each stream's parts are the difference, ignoring sign, between the target and the other stream; weights are those parts scaled to the batch.
- Three streams: the mass balances for total weight, fat and SNF are solved together. A negative answer means the targets cannot be reached with those streams.
- Every result is checked back by mass balance, as the article recommends.
