Abstract: A method is provided for producing a butter-like composition which has a taste, texture and mouth feel similar to butter but which is speadable at refrigeration temperatures. A feed of at least one liquid dairy product which is primarily and oil-in-water emulsion and has a fat content of at about 8% is prepared. The feed is concentrated by removing water until a concentrate having at least about 40% fat is obtained. The concentrate is homogenized and a phase reversal of the concentrate is caused, either prior to, during or after homogenization, so that the emulsion of the concentrate is converted from a primarily oil-in-water emulsion to a predominantly water-in-oil emulsion. The concentrate, thereby, forms a butter-like composition, and the ratio of oil-in-water emulsion to water-in-oil emulsion in the composition is at least about 6:4, and preferably between 7:3 and 8:2.

Abstract: A sensor for measuring the temperature of a liquid or semi-solid material by electrical heating. A core rod has disposed thereon a first electrically insulating member and a thin metal wire is wound about the first insulating member on the core rod. A second electrically insulating member covers the thin metal wire. When an electrical current is passed through the thin metal wire heat is generated in the thin metal wire. The resistance in the thin metal wire is proportional to the temperature thereof, which temperature is proportional to the current passed through the thin metal wire and the temperature of the liquid or semi-solid in which the sensor with the thin metal wire is disposed. Thus the temperature of the liquid or semi-solid can be determined by measuring the voltage or resistance in the thin metal wire by known measuring devices.
