  • Patent number: 4731248
    Abstract: The present invention relates to a process for the production of unique palatability enhancing materials, particularly suited for pet foods, from filamentous fungi biomasses. The palatability enhancing materials are produced by forming a slurry of a filamentous fungal biomass, and preferably an added proteinaceous material, such as meat, which is then autolyzed, in the absence of an added autolysis initiator, at a pH sufficient to form a palatability enhancing autolysate preferably at a pH of between about 2.5 and 10, most preferably of about 3.0 to 7.5. Autolysis is preferably performed at two distinct temperature stages during which endogenous protease and nuclease activity is initiated during the first stage and endogenous nuclease activity is increased during the second temperature stage, followed by substantial deactivation of endogenous protease activity.

  • Patent number: 4689381
    Abstract: A modified vegetable protein adhesive binder and a process for producing the same is disclosed wherein an alkaline protein dispersion is formed of a vegetable protein material and said dispersion is treated with a cationic monomer, preferably a cationic monomer selected from the group consisting of cationic epoxide monomers and cationic acrylate monomers, in an amount sufficient to modify the protein material. The modified vegetable protein adhesive binder has a greater affinity for pigments in a paper coating composition. This greater pigment affinity results in an improvement in the porosity of the final coating, thereby improving ink receptivity and printability on the coating surface.

  • Patent number: 4655161
    Abstract: An apparatus and method are provided for depositing chips of chocolate, fudge, and the like on food products. The apparatus comprises a hopper shaped to retain the chips therein, and a depositor roll having a peripheral surface with a plurality of recessed pockets into which the chips are received. A feed plate extends from an outlet portion of the hopper to the depositor roll at an elevation substantially commensurate with the longitudinal axis of the depositor roll. The feed plate preferably has a length which is greater than twice the dimension of one of the chips to form a dynamic, free-surface reservoir in which the chips temporarily pool prior to lodging in the depositor roll pockets. When the depositor roll is rotated, the chips continuously feed from the hopper, along the feed plate, and into the depositor roll pockets.
