The change to True Protein in federal milk
marketing orders is resulting in a strong move to true protein pricing by plants offering
cheese yield pricing programs. The chart below shows the amount of Cheddar cheese in 100
pounds of milk at various component levels. This table uses a modified Van Slyke Cheddar
formula using 90% fat recovery, a casein to fat ratio of 0.64:1, and 38% moisture cheese.
Different plants may use a different formula, depending on the type of cheese, fat
recovered in cheese, the casein-to-fat ratio, and cheese moisture levels.
Fat used in Cheese:
Cheese Fat % = Lower of
% True Protein in Milk x 0.829
0.64
OR % Fat in Milk
True Protein Formula:
Cheddar Cheese Yield =
( Cheese Fat % x 0.9 + True Protein % x 0.829 - 0.1 ) x 1.09
1 - Moisture
Note that the cheese yield does not
increase as you look down the shaded columns in the chart below. Once the casein-to-fat
ratio drops below 0.64:1, cheese yields do not increase with increased fat content. This
is because the amount of milk protein available limits the amount of fat useable in
cheese. The value of this additional milkfat is based on the butter price, rather than the
cheese price. Some plants do not adjust for the casein-to-fat ratio because they need the
all of the producer milkfat available to manufacture the type of cheese they are making.
