Apparatus and method for hydrolysis of a protein containing raw material and application of the resulting hydrolysis products

摘要

Apparatus and methods for hydrolyzing protein-containing raw material into water soluble protein and other products. The apparatuses and methods comprise an optional collection or processing stage in which protein-containing raw material, such as fish or animal carcasses from food production plants, are collected and optionally processed. The raw material is then reacted with one or more enzymes to hydrolyze the protein present, after which the one or more enzymes are inactivated and the components separated. The processes and apparatuses, which can be run as a batch processes or, advantageously as a continuous processes, can yield water soluble protein, oils, bone meal and other products that have utility as food or food additives.

主权项

1. A method for continuous, low emulsion hydrolysis of protein-containing raw material derived from the group consisting of fish, animal, and plant material comprising the steps of:
a) providing an apparatus comprising a hydrolysis area, an inactivation area, and a separation area; b) hydrolyzing said raw material in the hydrolysis area by reacting a reaction mixture comprising said raw material and at least one enzyme present in said hydrolysis area, wherein the reaction mixture contains both solids and liquid, and wherein upon hydrolysis, said reaction mixture further comprises hydrolysis product; c) inactivating said reaction mixture from the hydrolysis area in the inactivation area to substantially inactivate the enzyme present in the reaction mixture; and d) separating the reaction mixture in the separation area that receives at least a portion of the reaction mixture from the inactivation area and is capable of separating it into two or more components, including at least one substantially liquid component which comprises water-soluble protein; and including at least one substantially solid containing component; wherein the hydrolysis area, inactivation area, and separation area operate in a continuous mode and maintain an even and continuous flow mode of said reaction mixture; and operated such that any emulsion present in said liquid component is present in an amount is maintained below 10% of the reaction mixture.
