![]() Percent snf may be found same as for cream or by making a total solids test and deducting the percent fat. (d) Milk – Percent fat measured by an acceptable method. Example: In cream testing 30% fat, the percent snf would be (100 – 30) x. 09 = % snf (assuming that the “skim milk” contains 9% total solids). ![]() Percent MSNF found by formula as follows: (100 – percent fat) x. ![]() (c) Cream – Percent fat usually measured by an acceptable method. skim milk powder, whey powder, WPC, milk powder blends, usually taken to be 97 percent solids as they retain some moisture. Fat (0.01% – 0.10%) should be taken into account if significant. (a) Skim milk – can be determined by analysis or assumed at 9 percent serum solids. Information on the various ingredients is given below: In some cases the percentage of solids contained in a product is taken as constant, while in others the composition must be obtained by analysis. In standardizing mixes, the composition of the various ingredients used must be known. This method has solved the simultaneous equations in a general way so that only the equations need to be known and not resolved each time. Other commercial options are available from or įor manual calculations, a method known as the “Serum Point” method has been derived. For an example of a on-line mix calculator by subscription, see . A free on-line simultaneous equation solver is available at. To solve simultaneous equations, you need as many independent equations as you have unknowns. If there are two or more sources, for example we need 10 % fat and it is coming from both cream and milk, then we need to utilize an algebraic method.Ĭomputer programs developed for mix calculations generally solve a simultaneous equation based on mass and component balances. If there is only one source of the component we need for the formula, for example the stabilizer or the sugar, we determine it directly by multiplying the percentage we need by the amount we need, e.g., 100 kg of mix 10% sugar would require 10 kg sugar. The first step in a mix calculation is to identify for each ingredient we intend to use its components. Sweetener, supplied by dry or liquid (which also then supplies water) sucrose or corn syrup solids. Water, supplied by Skim milk (which also supplies msnf), or milk (which also supplies fat and msnf), or pure water.
