Abstract: The low calorie butter consists of choice grade or table butter, a first aqueous phase with a slightly acidic buffer substance and a second aqueous phase with milk albumens. A quantity of choice grade and/or table butter corresponding to a butter fat content of up to 60% by weight, based on the end product, is brought to a processing temperature of 15.degree. to 25.degree. C. and, is pushed in a tightly sealable machine by cutting blades operating with a high shearing force. During the subsequent mixing and kneading of the finely cut choice grade and/or table butter composition the first aqueous phase with 2 to 8% by weight, based on the end product, of natural lactic acid concentrate which buffers the aqueous phase of the end product to a pH of 5 to 6.5 is firstly added, then the second aqueous phase with 4 to 10% by weight, based on the end product, of alkali and/or alkaline earth caseinate is added. The components are mixed thoroughly by the kneading operation with a rise in temperature of 3.degree. to 5.
