Abstract: Anhydrous milk powder is prepared to have substantially the same constituent ingredients as dry whole milk powder that is manufactured using conventional processes, except that 100% of the fat constituent is available as fat. Whole milk is first separated into skim milk and anhydrous butter fat; the skim milk is dried by removing all of the available free water therefrom; and the resultant anhydrous skim milk powder solids are combined in a selected amount together with a further selected amount of the separated anhydrous butter fat constituent in a ribbon blender. The resultant blended product has the same constituent make-up as ordinary dry whole milk, but all of the fat constituent is recoverable as fat.

Abstract: Skimmed milk is subjected to acidification by electrodialysis in one or two successive three-compartment electrodialyzers. The resulting milk is at a pH of 4.5 or 2.8. Milk at a pH of 4.5 may be used for obtaining refined casein as a substitute for rennin casein.

The acid permeate is passed over a strong cationic resin in order to be used as an acid agent in the initial electrodialyzers.

Abstract: A method of and equipment for controlling the content of fat in milk. Whole milk is separated into skim milk. Some of the cream is returned to the skim milk to create a standardized milk. The standardized milk is employed to derive a parameter that dictates how much cream is to be added. The fat contents detected in the standardized milk are exploited to vary the amount of added cream. The density of the skim milk is measured at intervals and the results are stored. The density of the standardized milk is measured and more or less cream is added until a prescribed difference between the skim milk and the standardized milk, corresponding to the desired fat content in the standardized milk, is obtained. The density of the skim milk and that of the standardized milk are measured in the same sensor. The result of each measurement of the density of the skim milk is compared with the stored result.

Abstract: A process whereby sweetened condensed milk (SCM) or sweetened condensed skimmed milk (SCSM) is used as a starting material. The SCM or SCSM is pumped to a stainless steel refrigerated holding tank where it is diluted to 50.degree.-65.degree. brix (solids) with water. The product is then pumped into a continuous vacuum dryer, through a deaerator to control foaming and then into a feed pan. A stainless steel feed roll rotates in the feed pan and pick up SCM or SCSM product which then deposits a uniform layer of the SCM or SCSM on a continuous stainless steel belt. The clearance between the feed roll and the stainless steel belt is 0.015 to 0.025 inches. The SCM or SCSM product then goes through three heat zones at which vapor is driven off. Heat zone 1 preconcentrates and degasses the SCM or SCSM. This increases the area and volume of product so that it can withstand rapid evaporation occurring in heat zone 2. Heat zone 2 includes a hot drum at which a major portion of the drying occurs.

Abstract: Butter oil is heated under high vacuum and sparged for up to about 6 hours to remove cholesterol. Walls surrounding a vapor space above the sparged mass preferably are heated to remove cholesterol with reduced loss of desirable low molecular weight components. Alternatively, the temperature of the butter oil is lowered, and the butter oil is sparged with steam for an additional period of up to about 3 hours to partially hydrolyze triglycerides to mono- and di-glycerides and free fatty acids. The low cholesterol butter oil then is cooled before being exposed to air, thus avoiding oxidation which produces off-flavors. The resulting low-cholesterol butter fat and products made therefrom have composition and organoleptic characteristics substantially similar to those of natural butter oil and butter.
