Ask the Diva: Is Ultra-Pasteurized Milk Less Nutritious?
Q. Most of organic milk in my grocery store is “ultra-pasteurized.” Does ultra-pasteurized milk have fewer vitamins or calcium than regular milk?
A. Ultra-pasteurization extends the shelf life of milk from a couple of weeks to a couple of months. They do it by heating the milk to about 260 degrees Fahrenheit (regular pasteurization is at 160 degrees F). It won’t affect the nutritional quality of the milk, but, in my opinion, it does affect the flavor. To me, ultra-pasteurized milk has a slightly flat, stale taste. Your best bet for organic milk that has not been ultra-pasteurized is to find a small, local dairy. You can search for local vendors at LocalHarvest.org.
