Buttermilk powder is a dried milk product used as a commercial ingredient. The figures here are calculated from uncultured buttermilk and refer to the powder rather than a prepared drink. It mainly provides carbohydrate and protein, with some fat. Per 100g, it contains 51g of carbohydrate, all of which is sugar, 34g of protein, 5.1g of fat and 1210mg of calcium.

Protein supports the maintenance and repair of body tissues, while calcium contributes to normal bones and teeth. The sugars in uncultured buttermilk are mainly lactose, the naturally occurring sugar in milk, which may be relevant to people with lactose intolerance. Salt and saturated fat content are also worth noting when comparing ingredients. Full nutrient figures are in the tables below.

About these figures

Values are per 100g of the food as described (Commercial ingredient, calculated from uncultured buttermilk). "Trace" means only a very small amount was found. Nutrients that were not measured are not shown. Salt is calculated from sodium.

These figures come from an older part of the dataset that is no longer updated. Original source: Milk Products and Eggs Supplement, 1989.
