Spotting the Allergen: Milk Protein

It seems ironic that the food on which most babies thrive, can be dangerous and even fatal for others.  Milk is the most common food allergy in children, affecting 2.5% of children under 3. An allergic reaction is triggered by proteins in cow’s milk called caseins.  In many cases it is obvious which foods contain dairy products, but is surprising how many seemingly “dairy-free” products contain casein.  Even though it is required by law for manufacturers to list "milk" on the product label if applicable, it is still worthwhile to be familiar with the following foods and ingredients.

Food containing milk:
  • Butter, butter fat, butter oil, butter flavoring, butter acid, butter ester
  • Buttermilk
  • Cheese
  • Cottage cheese

  • Half-and-half
  • Milk in any form (evaporated, powdered, etc)
  • Pudding
  • Racaldent (strengthens teeth)
  • Sour cream
  • Sour milk
  • Yogurt
  • Frozen yogurt
  • Goats milk (has a similar protein to cow’s milk)
  • Brown sugar flavoring

Ingredients containing milk protein:
  • Casein, calcium casein, casein hydrolysate, magnesium casein, potassium casein, rennet casein, sodium casein, caseinates (all forms)
  • Lactalbumin, lactoalbumin phosphate, lactablobulin, lactose, lactoferrin, lactulose
  • Whey, whey hydrolysate
  • Diacetyl
  • Tagatose (sweetener)
  •  
Ingredients that DO NOT contain milk protein:
  • Calcium lactate
  • Calcium stearoyl lactylate
  • Cocoa butter
  • Cream of tartar
  • Lactic acid (lactic acid starter culture may contain milk)
