Work out milk standardisation (pearson square) instantly with clear inputs, formula shown and shareable results.
The Pearson square solves a two-stream blend: parts of the higher-fat stream equal the target minus the lower fat, and parts of the lower-fat stream equal the higher fat minus the target. Scaling those parts to the batch volume gives the quantity of each. The target must lie between the two stream values.
Pearson square
Parts of high stream = target - low fat; parts of low stream = high fat - target
Volumes
Volume = batch x parts / total parts
Yes, for any single component blended from two streams. It is simply a linear mass balance and works for fat, protein, total solids or added ingredient percentage.
The Pearson square cannot handle it. Use simultaneous mass balance equations, or fix one stream's quantity and apply the square to the remaining two.
