General Information
Casein is the most widely used refined protein source, but it is also possible to use other refined protein sources, such as "vitamin-free" test casein (alcohol extracted), lactalbumin, isolated soy protein, and egg white solids. These particular protein sources are usually used to achieve a specific research objective, rather than for routine use. For instance, vitamin-free test casein is most appropriately used in vitamin deficient diets, and egg white solids is most suitable for zinc or biotin deficient diets.

Adjusted protein diets usually range from "protein-free" (trace) and 50% protein, depending on the research. A few examples are shown from a series of diets with the following features: casein-based, isocaloric (3.8 kcal/g) and matched for fat (5.5%), calcium (0.7%), and phosphorus (0.54%).
