Calculations for Frozen Foods - TechWizard™ is an excellent tool for formulating and evaluating frozen products. If a product is stored and/or served frozen then the size of the ice crystals and the total amount of ice in the product can have a tremendous influence on texture and/or stability. TechWizard can be used to estimate the ice content of a product. 

A good example of this is using TechWizard™ to evaluate frozen desserts. The following discussion considers estimating the ice content of a frozen dessert. 

The freezing characteristics of a mix can be determined based on % water frozen or % product frozen. The % water frozen term is the more common term used in relation to frozen desserts. The term can be explained by the following example. If a liquid mix contains 40% total solids then the rest of the mix is water, i.e.; the water content is 60%. If 50% of the water in the mix is frozen (50 % water frozen) then half of the 60% water is frozen meaning that the mix contains 30 g of ice for 100 g of product. This leads us to the other term used to express freezing characteristics, % product frozen. The % product frozen is simply the grams of ice per 100 grams of product. A value of 50% product frozen means that it contains 50 grams of ice per 100 grams of product.
