  • Patent number: 5503112
    Abstract: The present invention includes a method of formulating ruminant feed to selectively change a composition of milk produced by the ruminant. The method includes providing a fistula directly into an abomasum of the ruminant. A selected feed component at a selected level is introduced directly into the abomasum through the ingress. The selected feed component thereby bypasses other portions of the ruminant's stomach. The direct introduction of the selected feed component allows for changing a selected characteristic of the composition of milk. The composition of the milk corresponding to the selected feed component is then analyzed. The direct introduction of the selected feed component is repeated, if necessary, at other selected levels. The milk produced corresponding to the other selected levels is then analyzed.

  • Patent number: 5006349
    Abstract: A protein product is produced by a process that includes introducing a protein-containing fluid and a reactant stream containing a component reactive with the protein, such as an acid through a resonating chamber. The protein-containing fluid and acid are introduced into the chamber at a velocity and pressure which causes instantaneous mixing of the protein-containing fluid with the acid to form an acidified mixture. The acid is introduced into the chamber in a ratio such that the pH of the protein-containing fluid is lowered past the isoelectric point of the protein.

  • Patent number: 4873094
    Abstract: An acidified dairy cream characterized by a non-grainy texture and the absence of cooked flavors is made by acidifying dairy-derived cream to a pH level of approximately 4.6 or below. The cream is then heated to a range of 222.degree. F. to 264.degree. F. while being subjected to a pressure of at least approximately 180 psig. The cream is then aseptically packaged.

  • Patent number: 4648506
    Abstract: A package with spreader is hermetically sealed for storing relatively stiff spreadable materials such as butter until ready for use. The package includes a base having a relatively stiff spreader blade partially defined by a blade spread side surface and an opposed base supply side. The base also includes a deformable blister for holding the spreadable material. The blister is open through the blade to its spread side surface and extends outwardly from the blade on the supply side of the base. A peelable membrane initially seals the butter inside of the blister by being in sealing relation to the spread side surface of the blade. A portion of the membrane is manually peelable from sealing relation with respect to part of the blade and uncovers a portion of the blister to provide a butter delivery opening through which the butter can be forced by digital pressure on the outside of the blister. The butter can then be immediately spread using the sealing side surface of the blade.

  • Patent number: 4552774
    Abstract: A process for making a cheese-like product includes blending shredded cheese with a composition containing water, milk solids and functional whey proteins to form a mixture. Starch is added to the mixture up to 10% of the weight of the mixture. The mixture is then heated to an approximate temperature range of 140.degree. F. to 190.degree. F. and the starch and functional whey protein are permitted to gel and the cheese permitted to melt. The gelled mixture is then processed to reduce the cheese protein to an approximate particle size range of 5 to 325 microns.

  • Patent number: 4543264
    Abstract: A bland and nutritive oilseed food product made from an oil seed having a fat content of at least approximately 10% and a protein content of at least approximately 20% is produced by a process involving the steps of heating a particulate oilseed material with steam to preferably 220.degree. F. and subjecting the particulate oilseed material to lower alcohol vapors. Initially, the oilseed material is placed in a closed vessel and the alcohol is added to the oilseed material in a preferred weight ratio of approximately 9 pounds alcohol to 60 pounds oilseed material along with a small quantity of water. The vessel has agitators that agitate the oilseed material sufficiently to "fluidize" the material within the vessel. Steam is injected into the vessel and when the temperature of the oilseed material preferably reaches 220.degree. F., the steam is stopped and the particulate oilseed material is kept at that temperature in the closed vessel for at least thirty minutes.

  • Patent number: 4447463
    Abstract: A churn-free process for producing a spreadable dairy product includes the steps of: providing a cream having a fat content in the preferred range of approximately 38-42% butterfat; concentrating the cream to increase the fat content to at least 80% butterfat; processing the cream through a homogenizer such that the cream is inverted from an oil-in-water emulsion to a water-in-oil emulsion; adding a liquid vegetable oil to the water-in-oil emulsion; and cooling the vegetable oil/cream mixture sufficiently, preferably through a swept-surface heat exchanger, such that a viscous spread-like mixture is produced.

  • Patent number: 4425370
    Abstract: A process for producing a margarine-type food product includes the steps of: blending a dairy substance such as skim milk with a hydrogenated vegetable oil in approximately a 60/40 ratio; processing the skim milk/oil mixture through a homogenizer to obtain an oil globule size range essentially similar to a fat globule size range found in dairy cream; blending a dairy cream with the homogenized skim milk/oil mixture; and processing the mixture of dairy cream and skim milk/oil through a butter churning process.

  • Patent number: 4289793
    Abstract: Large blocks of cheese are formed in a container having a removable bottom, side walls, and an essentially open top. A plurality of upstanding perforated tapered posts extend from the removable bottom to essentially the desired final height of the cheese block. The posts are longitudinally and laterally spaced from one another so that the curd surrounds each post when the container is filled with curd. Pressure is then applied downward to the curd in the container which compacts the curd and causes draining of whey through the upstanding perforated posts. After the curd has been compacted to the desired height, and the whey has been drained through the upstanding perforated posts, the container is inverted and the tapered posts are withdrawn. Pressure is again applied to cause the curd surrounding each perforated post to knit together and aid in removal of any additional whey, thereby providing a cheese block of uniform texture.
