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. Whey powder (which also supplies water).Sweetened condensed (which also supplies water and sugar).Condensed milk (which also supplies water and fat).Condensed skim (which also supplies water).Skim powder (which also supplies water, about 3%).Milk solids-not-fat (SNF, or sometimes also called serum solids, S.S.), supplied by any of the following: ![]() Milkfat, supplied by Cream (which also supplies SNF and water) or Butter (which also supplies SNF, water) The following table illustrates the relationship between the major components, the main ingredients that supply the major components, and the minor components that are supplied with the major ones for each ingredient.Ĭomponent and Ingredients to supply that component (but note that each of these ingredients also supplies the following other components): In this section, I include several examples of how to calculate mix recipes based on desired formulations. The complexity is that several ingredients will supply more than one componet, for example cream contains all of milkfat, milk SNF and water. The ingredients to supply these components are chosen on the basis of availability, quality and cost, for example cream or butter as a fat source, skim milk powder or condensed skim milk as SNF sources. The formula is given as percentages of fat, milk solids-not-fat, sugar, corn syrup solids (glucose solids), stabilizers, emulsifiers or other mix components. The general objective in calculating ice cream mixes is to turn your formula into a recipe based on the ingredients you intend to use and the amount of mix you desire. ![]() Calculations for Ice Cream and Frozen Dairy Desserts 19 Mix Calculations
