Instructions & Example Calculation

Instructions

Enter the concentration of the high source, low source, and desired target percentage. Provide the total target weight/volume to calculate the exact mix weights.

Example Calculation

To standardise cream fat to 3.5% using 40% cream and 1.5% milk: Parts of cream needed = 3.5 – 1.5 = 2.0 parts. Parts of milk needed = 40.0 – 3.5 = 36.5 parts. Total parts = 38.5. For a 100 kg batch, this requires 5.19 kg of cream and 94.81 kg of milk.
