Dairyscience Calculators and models
Site calculators and models
This section provides an access point to a range of calculators and models. These include calculators for determining the theoretical yields of Cheddar cheese (Van Slyke), the yield of Cottage cheese, the volumes of skim and whole milk required to standardise milk to a required fat content, the predicted grade value of Cheddar cheese, casein retention, fat retention, casein to fat ratio, protein to fat ratio, the quantities of ingredients required for a balanced ice cream mix, the ideal MSNF value for ice cream, MSNF in unwashed butter, MSNF in cream and the energy value of foods. Software for calculating the F value of thermal processes has also been provided. This software can be used to teach the principles of thermal processing or to check the adequacy of, for example, a canning process. It is easy to use and applicable to a broad range of thermal processes.
