The Standard of Identity for ice cream requires that it contain a minimum of ________ percent milk fat.

The correct choice is 10 percent milk fat because the Standard of Identity for ice cream, as established by the Food and Drug Administration (FDA), specifies that ice cream must contain a minimum of 10 percent milk fat. This regulation ensures that the product meets certain quality and richness parameters, contributing to its texture, flavor, and overall sensory experience. Ice cream's creaminess and mouthfeel are significantly influenced by the fat content; hence, maintaining a standard minimum is crucial for producing a product that aligns with consumer expectations and industry standards.
