Calculate Protein and Fat levels from home made food

Clubman

Making a bit of beef jerky at home and just looking to calculate the protein and fat levels. Ive no idea how to go about this, probably a science question.

Pointers in the right direction would be appreciated.

MyFitnessPal. Stick in the ingredients and amounts. If you get the app there's also a barcode scanner. Very useful!

Many packs will have the info on it, if you are not trimming off anything then you just use these figures after adjusting for loss of moisture content.

e.g. say you had 200g of steak and it was listed as 5% fat and 20% protein.

If this dried down to 120g after cooking/curing, then 200/120=1.66

Your protein is now 33.33% (1.66x20%)and fat is 8.33%.

If you are cooking high fat beef then the fat is obviously falling off and so harder to calculate.

You can double check your results easily enough
200gx20%=40g
120x33.3%=40g

You can just work it out at the start, no need to factor in dried/initial weight.

There is another application for iphone called shape up.. My fitness Pal is also a really good one! I don't really know which one is better.. Check it!

I guessed he is making a large batch of it which he will store and weigh out as he gets through it gradually.
