  • Patent number: 6676840
    Abstract: The precipitation and removal of suspended fat and protein components and other suspended solids from a given solution can be accomplished by the addition of an aluminate to complex with the fat and protein components and the addition of a flocculating agent to flocculate the aluminate/fat and protein component complexes into insoluble particles capable of removal by conventional technology, which insoluble particles can be rendered to produce tallow.
