Nonfat yogurt must have a maximum percentage of fat prior to the addition of bulky flavors. What is this percentage?

Nonfat yogurt is specifically defined by regulations that limit its fat content to ensure that it can be classified as "nonfat." The maximum percentage of fat allowed in nonfat yogurt prior to the addition of bulky flavors is indeed 0.5%. This standard helps to maintain the product's designation as nonfat while allowing for the incorporation of flavors and other ingredients that might add some complexity to the yogurt's profile.

Maintaining this low fat content is crucial for both nutritional labeling and for consumers who are seeking nonfat options for dietary reasons. This definition is supported by industry standards and regulations designed to differentiate between full-fat, low-fat, and nonfat dairy products. Most other options provided (1.0%, 2.0%, and 3.0%) exceed this limit, which would classify the yogurt differently and not align with the nonfat designation.
