There is a brand of orange juice here in the U.S. that is calcium enriched. The ingredients show CALCIUM LACTATE as the ingredient that is added to provide the calcium. Is that a dairy ingredient? Is the orange juice milchig?

Dear Sheldon Rothman,

Often, questions such as yours can best be answered by the kashrut agencies that deal with these issues on a day-to-day basis. So I forwarded your question to the Orthodox Union kashrut department. Here is their answer:

"Thank you for your inquiry to the OU 'Vebbe Rebbe.' In response to your question: Calcium Lactate is not a dairy ingredient.
