Losses of elements vary considerably with the method of cooking
employed, being of course greatest where small pieces of meat are
subjected to prolonged cooking. The chief loss in weight when meat is
cooked is due to the driving off of water. When beef is cooked by pan
broiling--that is, searing in a hot, greased pan, a common cooking
process--no great loss of nutrition results, particularly if the fat and
other substances adhering to the pan are utilized in the preparation of
gravy. When beef is cooked by boiling, there is a loss of 3 to 20 per
cent. of material present, though this is not an actual loss if the
broth is utilized for soup or in some similar way. Even in the case of
meat which is used for the preparation of beef tea or broth, the losses
of nutritive material are apparently small though much of the flavoring
matter has been removed. The amount of fat found in broth varies
directly with the amount originally present in the meat; the fatter the
meat the greater the quantity of fat in the broth. The loss of water
in cooking varies inversely with the fatness of the meat; that is,
the fatter the meat the smaller the shrinkage due to loss of water.
In cooked meat the loss of various constituents is inversely proportional
to the size of the cut. In other words, the smaller the piece of meat
the greater the percentage of loss. Loss also appears to be dependent
somewhat upon the length of time the cooking is continued. When pieces
of meat weighing 1-1/2 to 5 pounds are cooked in water somewhat under
the boiling point there appears to be little difference in the amount of
material found in broth whether the meat is placed in cold water or hot
water at the beginning of the cooking period. When meat is roasted in
the oven the amount of material removed is somewhat affected by the
character of the roasting pan and similar factors, thus the total loss
in weight is naturally greater in an open than in a closed pan as the
open pan offers more opportunity for the evaporation of water. Judging
from the average results of a considerable number of tests, it appears
that a roast weighing 6 pounds raw should weigh 5 pounds after cooking,
or in other words the loss is about one-sixth of the original weight.
This means that if the raw meat costs 20 cents per pound the cooked
would represent an increase of 4 cents a pound on the original cost;
but this increase would, of course, be lessened if all the drippings
and gravy are utilized.
