    • A particulate proteinaceous product and methods for producing the same from waste raw animal parts are disclosed. The product is dry to the touch, is compressible into pellets or cakes, and comprises about 45 to 65 w/w percent partially hydrolyzed, non-denatured animal protein, about 20-35 w/w percent oil derived from the animal parts, about 10-15 w/w percent moisture, and about 0-7 w/w percent ash. The product also has less objectionable odor, less propensity to oxidize, and higher nutritional value than existing products. The method comprises a mulling stage wherein the raw animal parts are reduced to a ground condition; a hydrolyzing stage wherein proteins in the ground animal parts are hydrolyzed to a predetermined extent to form an aqueous suspension, using either endogenous or supplementary proteolytic enzymes, and subsequently heated to inactivate the enzymes and convert fats in the suspension to oils; a screening stage wherein non-digestible solids are removed from the suspension; a concentration stage wherein extraneous oil is added to the suspension, the suspension is pasteurized, and a large portion of the water is removed therefrom; and an oil-separation stage wherein sufficient oil is removed to form the product. A portion of the removed oil is routed back to the beginning of the concentration stage as extraneous oil added to the suspension to permit sufficient water to be removed from the suspension without forming a stiff, unprocessable mass. The method is distinctive in that it produces a dry, flaky product without the use of a conventional dryer. The method is also distinctive for its substantial resistance to equipment clogging.
    • 公开了一种颗粒状蛋白质产品及其从废物生物动物部件制备该颗粒蛋白质产品的方法。 该产品是干燥的,可压缩成颗粒或蛋糕,并且包含约45至65w / w%的部分水解的非变性动物蛋白,约20-35w / w%的衍生自动物部件的油,约 10-15w / w%的水分和约0-7w / w%的灰分。 该产品还具有较少的异味,较少的氧化倾向,以及比现有产品更高的营养价值。 该方法包括将生物动物部分还原成地面状态的研磨阶段; 水解阶段,其中将研磨动物部分中的蛋白质水解至预定程度以形成含水悬浮液,使用内源或补充蛋白水解酶,随后加热灭活酶并将悬浮液中的脂肪转化为油; 筛选阶段,其中从所述悬浮液中除去不可消化的固体; 向悬浮液中加入外来油的浓缩阶段,将该悬浮液巴氏灭菌,并从中除去大部分水分; 以及其中除去足够的油以形成产物的油分离阶段。 去除的油的一部分被返回到浓缩阶段的开始,作为添加到悬浮液中的外来油,以允许从悬浮液中除去足够的水而不形成刚性的,不可加工的物质。 该方法是独特的,因为它在不使用常规干燥器的情况下产生干燥的片状产品。 该方法也具有显着的抵抗设备堵塞的特征。
