  • Patent number: 4352692
    Abstract: A modified vegetable protein adhesive binder and process for its production is disclosed comprising; forming a slurry of a urease containing vegetable protein material having a proteinaceous solids content of 10 to 30% by weight and including in said slurry a quantity of water soluble silicate to minimize foaming during reaction of the protein material. Urea is then added which reacts with the urease to liberate ammonia from the urea and raise the pH of the slurry to above about 8. The slurry having an alkaline pH is reacted with an oxidizing agent to modify the protein, followed by heating of the modified protein at a temperature of 220-320.degree. F. The modified protein material is then cooled and dried to result in a protein adhesive binder with excellent rheological properties and good coating characteristics.

  • Patent number: 4311713
    Abstract: A composition for limiting feed supplement intake for animals is disclosed which comprises an acidulated fat, wherein acidulation of the fat is carried out at a temperature of at least about 220.degree. F. with an acid, preferably a mineral acid. The acidulated fat can be incorporated into the feed supplement at a level exceeding 1.5% by weight to control intake or combined with other intake limiters such as meat meal, diammonium phosphate, and ammonium sulfate for intake control. This composition controls feed supplement intake by the animal when added thereto, permitting self-rationed feeding without waste.

  • Patent number: 4309344
    Abstract: A simplified process for the production of a protein isolate from defatted vegetable protein material is disclosed which comprises extracting a defatted vegetable protein material with an aqueous extractant to provide a protein extract, followed by adjustment of the pH of said extract to the isoelectric point of the protein to provide a protein precipitate. The protein precipitate is thereafter heated to a temperature between about 115.degree.-145.degree. F. and concentrated to a solids level of at least about 44% by weight. This unexpectedly results in the production of a protein isolate which has an improved degree of whiteness over those isolates produced by prior art techniques.

  • Patent number: 4269865
    Abstract: A process for the conversion of feathers into a foodstuff is disclosed wherein moistened feathers are subjected to an elevated temperature and a pressure of 15-40 psig without agitation to form a pulpy mass of the feathers. The pulpy mass of feathers is then hydrolyzed at a pressure of 40-80 psig, to convert the feathers into a highly nutritious food product. The converted feathers can be dried to form a highly nutritious feather meal or combined with other poultry by-products such as offal or blood to form an aggregate or mixture of these by-products.

  • Patent number: 4258667
    Abstract: The present invention comprises an improved animal dust bag for holding and dispensing powdered insecticide. The bag arrangement permits the bag to be hung from two spaced apart points when it is desired to avoid turning of the bag, or from a single overhead point when turning of the bag is of no concern. A flap extends upwardly from the top of the bag and presents an eyelet for receiving the two tie strings. When the two tie strings are threaded through the eyelet there is virtually no possibility of an animal sticking its head or a horn between the tie strings and pulling down the bag or damaging it. The eyelet also assures that the bag will be held relatively even, thus avoiding compaction of the powdered insecticide in one corner. A horizontal hanger bar extends across the top of the bag and presents two eyelets on either side so that when attachment at two spaced apart points is desired, the two eyelets of the hanger bar will avoid strain being placed on the bag material itself.

  • Patent number: 4234604
    Abstract: A composition for limiting feed supplement intake for ruminants is disclosed which comprises a chlorinated fat having a reacted chlorine content in an amount effective to limit intake or usually between about 0.2 and 7.0% by weight of said fat. The chlorinated fat can be incorporated into a feed supplement at a level effective to limit intake, preferably at a level exceeding 1.0% by weight, in addition to being employed with other intake limiters such as meat meal, diammonium phosphate, and ammonium sulfate in a feed supplement for intake control. The noted composition controls feed supplement intake by ruminants when added thereto permitting self-rationed feeding without waste.
