Can You Label Your Food Dairy-Free? The Rules
Dairy-free sells to a big, worried audience: people with a milk allergy and people avoiding lactose. Here is the catch most sellers miss. The FDA has never defined dairy-free, the related term non-dairy can legally contain a milk protein, and milk is one of the major allergens you have to declare no matter what. Here is how to use the words without misleading the buyer who needs them most.
Dairy-free is not an FDA-defined term
The FDA has never set a standard for dairy-free. There is no threshold and no certification the government requires, so it is a voluntary claim held only to the general rule that a label be truthful and not misleading. Because the people who look for dairy-free often have a milk allergy, a wrong claim here is not a marketing slip, it is a safety problem.
Non-dairy and lactose-free are not the same as milk-free
Non-dairy is defined in FDA regulations at 21 CFR 101.4, and here is the surprise: it can legally contain a milk-derived ingredient like sodium caseinate as long as that ingredient is declared. Non-dairy coffee creamer is the classic example. Lactose-free, also undefined by the FDA, points at the milk sugar lactose, not the milk protein, so a lactose-free food can still contain the protein a milk allergy reacts to.
Lactose intolerance and a milk allergy are different conditions. Mixing up these words on a label can send the wrong signal to the person for whom it matters most, so say only what is true of your food.
Milk is a major allergen you must declare
Whatever front-label word you use, milk is one of the nine major food allergens under U.S. law, and any milk ingredient has to be named, either in the ingredient list or in a Contains: Milk statement. A dairy-free claim does not remove that duty. Cross-contact with milk on shared equipment is worth a voluntary caution on top of it.
What Nutripane does and does not do
Nutripane reads your recipe and flags milk in the ingredient list and the allergen line, so the panel is honest about what is in the food. It cannot verify that your kitchen is free of milk cross-contact, because that depends on your equipment and process, not the layout. Make a dairy-free claim only when your ingredients and your kitchen both back it up.
Questions
Is dairy-free the same as milk-free?
Not necessarily. The FDA has not defined dairy-free, and the related term non-dairy can legally contain a milk protein like caseinate. Milk is a major allergen that must be declared either way, so a person with a milk allergy should read the ingredient list and the Contains line, not just the front label.
Can I call my food dairy-free if it is made in a kitchen that also uses butter?
Only carefully. A dairy-free claim has to be truthful and not misleading, and cross-contact with milk in a shared kitchen can make it misleading for an allergic buyer. If milk is used on the same equipment, a voluntary caution like made in a kitchen that also handles milk is the honest thing to add.
