Abstract: A process for the production of a pet food product resembling a "cooked" hamburger patty is set forth, which has a moisture content exceeding about 40% by weight and is stabilized against bacterial and mycotic penetration comprising: grinding raw animal meat into particles of a substantially uniform size, heating the same and impregnating the meat with a preservative composition which comprises a mixture of a bacteriostatic agent and an edible antimycotic. A critically defined range of expanded protein pieces are added to the final product which is between about 25 to 90% by volume of the product. The addition of a critically defined percentage of the expanded protein pieces provides a realistic chunky appearance and gives the product a shear value which exceeds about .080 ft. lb./gram. The bacteriostatic agent is preferably an organic acid selected from the group consisting of succinic acid, pyruvic acid, fumaric acid, adipic acid, glucono-.DELTA.

Abstract: A method of production of animal feed pellets made from oleaginous seeds and containing high levels of fat or other nutrient material. More particularly, hard, dry high fat feed pellets containing up to 50% fat are produced with the fat incorporated prior to the pelleting operation and is thereby distributed throughout the pellet.

Abstract: A method of continuously forming elongated protein filaments from a cooked meat source is disclosed which comprises forming an aqueous slurry of a cooked meat source having a solids content of at least about 10 percent by weight and a pH of between about 3 and 10, followed by treatment of the noted slurry to provide a pumpable slurry with a viscosity ratio, as measured at a solids level of 15 percent by weight, to an uncooked meat slurry of substantially identical composition of at least about 1:2. Elongated protein filaments are thereafter formed from the slurry by continuously conducting the slurry under pressure through a heat exchanger and heating the slurry to a critical temperature of at least about 280.degree. F. and preferably between about 310.degree. - 335.degree. F. while the protein is subjected to such temperature for a sufficient period of time so that elongated filaments are separated from the slurry.

Abstract: Meats are effectively pumped in excess of 140% of their green weights, yet maintain their original proteinaceous posture and nutritional value by a critically controlled preparation and injection of a protein medium. A salt tolerance protein isolate is hydrated in water and subsequently curing salts are admixed to the hydrated salt tolerant protein isolate. Upon curing the liquid medium, which has been pumped into the meat, cooks to a uniformly distributed, meat-like gel, the extra pumped meat product maintains the same nutritional protein value and substantially identical textural properties of natural meat tissue, the protein substantially retains its hydrated form in the final product and there is substantially no protein separation.

Abstract: A novel protein food product having a porous expanded structure with the texture and organoleptic properties of meat, is produced by a process which comprises: forming a mixture of a vegetable protein containing material and a meat source in an amount of between about 5 to 80% by weight, said mixture having a protein content on a dry basis of at least about 25% by weight, followed by extrusion of said mixture to form a porous expanded food product. The extrusion of a meat source and vegetable protein material provides a product having the economic and functional advantages of a simulated meat piece derived solely from a vegetable protein containing material, with the palatability of a real piece of meat because of the use of a meat source in the product.

Abstract: A novel protein isolate derived from vegetable oilseed protein is disclosed that is substantially free of impurities. More particularly, a novel soy protein isolate is disclosed which is substantially devoid of color and lacks the characteristic "beany" flavor of soybeans. The protein isolate is produced by extracting a ground oilseed material, such as soybean meal, with an alkaline extractant to provide an alkaline protein extract with a pH of at least about 9.5, passing the alkaline extract through activated carbon to deflavorize and decolorize the protein material, followed by precipitation and isolation of the deflavorized protein.

Abstract: A complete maintenance, nutritionally balanced animal food composition of a moisture content of about 75% is presented which incorporates expanded soybean fiber chunks throughout to simulate natural meat chunks and to resemble a canned all meat product, said chunks having been impregnated with flavorful components to impart a meat-like taste and consistency thereto, and a process for producing said food composition comprising: grinding raw animal meat containing proteinaceous material to particles of a substantially uniform size; mixing expanded soybean fiber chunks, moisture and oils therewith; cooking the slurry of said chunks to impregnate them with flavorful components of said particles of meat, flavors and oils for consistency and taste, the cooking being carried out at a sufficient moisture content to allow the food compositin to resemble a canned, all meat food product; then forming a nutritionally balanced food composition with the cooked slurry; packing the food composition into a container; and cook

Abstract: Fruit drinks which contain residual sulfur dioxide will have improved taste and odor and improved vitamin C retension if packaged in a substantially gas permeable container.

Abstract: The present invention is an extruded horse feed having size, shape, surface texture, and ingredient constituency which characterize unexpectedly good palatability and increased available energy supply such that the feed is uniquely capable of improving the consistency of horses' performance.

Abstract: A method of producing an expanded product which resembles meat, directly from soybean meal itself, including the steps of utilizing soybean meal that has substantially all the fat removed to an amount of about 5% or less, and preferably 2% or less, moistening the soybean meal such as mixing the soybean meal with water to obtain a moisture content of about 20%-40% by weight, controlling the pH within the range of 5 to 12, preferably 6 to 9, preferably adding an edible pH altering electrolyte while maintaining the controlled pH, and then simultaneously, mechanically working, heating above 212.degree. F., and pressurizing the moistened soybean meal in an extruder chamber sufficiently to cause continuous conversion of the meal to a flowable substance, and forcing the substance through and out of restricted orifice means to expand it into a lattice network structure having resilience, body strength, and appearance approaching that of meat.
