Abstract: A plant for manufacturing a dairy preparation made of skim milk and vegatable oil has a first area where the powdered milk is reconstituted to produce liquid skimmed milk to be used, a hot water-oil emulsion area, and a milk water-oil emulsion injection area. The plant further includes static and dynamic mixers, standardization tanks and storage tanks positioned prior to a heater, where the preparation is subject to a sudden heating at temperature 150.degree. for no longer than 4 seconds.

Abstract: A dairy preparation comprising a mixture of skimmed milk with vegetable oil. The animal fat contained in the milk, rich in saturated fatty acids and cholesterol, is removed and largely replaced with oils rich in monounsaturated fatty acids, for instance olive, sunflower and peanut oils. The preparation obtained maintains all the advantage of skimmed milk and is added with vitamins A, D.sub.3 and C. The process of making the dairy preparation starts with the use of liquid or powdered skimmed milk, the latter being reconstituted at a controlled temperature of at least 70.degree. C., and then combined with a hot water-oil emulsion, the necessary and suitable amounts of vitamins A, D.sub.3 and C being added. The preparation is subjected to a sudden heating at temperature 150.degree. C. for no longer than 4 seconds.
