Fat % - How Calculate?
« on: September 07, 2012, 02:48:53 PM »
I am making a Neufchatel type cheese. I add 1/2 pint heavy cream per gallon raw goat milk.
Can some one tell me how much fat by percentage I have going into my vat?

Heavy cream is 36% My milk is around 3.75%
Not even sure what formula I would use? I need to know because the Temp at which I pasteurize depends on fat content.
Thanks

5.647%

Weighted Average

1 part cream, 16 parts milk
cream is 6% of the total; 6% * 36% fat = 2.118%
milk is 94% of the total; 94% * 3,75% fat = 3.529%

Add them up for 5.647.

Another way to look at it is to look at how much fat is present divided by how much total volume you have.

1/2 pint at 36% = .18 pint of fat in the cream added

.0375 x 8 = .3 pints of fat in the milk  (8 pints per gallon at 3.75%)
.18+.3=.48 pints of fat total
.48/8.5=.05647 or...5.647%  (8.5 pints total volume...1 gallon milk and .5 pint cream)
