It has been found according to the invention, that a biomass containing an oxidation-sensitive material of value may be dried under particularly mild conditions by a method in which the drying gas is passed over the biomass to be dried in cycle gas mode.

It is an object of the present invention to provide a practical means for generating a cysteine from a protein, which is suitable for utilization in the field of food products (food product use). According to the present invention, there is provided a method for producing a cysteine-containing proteolytic product, comprising; allowing a -glutamyl peptide hydrolase, a filamentous fungi-derived protease, and a bacterial protease to act on a protein material.

The invention relates to the uses of a new characterized TET protein showed restricted to N-terminus glycine residues exopeptidase. The invention also relates to a method comprising said use of said new characterized TET protein as a N-terminus glycine residues specific exopeptidase. The invention further relates to a support wherein it is immobilized on said new characterized TET protein as a N-terminus glycine residues specific exopeptidase.

More specifically, the disclosure provides process and system that simultaneously producing oxygenated hydrocarbon compounds at high specific productivity while effectively extracting nutrient supplement products from microbial biomass.

Methods of using thermostable serine proteases are described herein.

The present invention relates to a polypeptide having proline-specific endoprotease activity, selected from the group consisting of i. a polypeptide comprising a mature polypeptide sequence of SEQ ID NO: 2; ii. a polypeptide that has least 70%, 75%, 80%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98% or 99% identity to the mature polypeptide sequence of SEQ ID NO: 2; iii. a polypeptide encoded by a nucleic acid that hybridizes under medium stringency, preferably under high stringency conditions to the complementary strand of the mature polypeptide coding sequence of SEQ ID NO:1; iv. a polypeptide encoded by a nucleic acid that has at least 70%, 75% 80%, 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or 100% identity to the mature polypeptide coding sequence of SEQ ID NO: 1.
The invention further relates to a method of producing the polypeptide and a process for the preparation of a food or feed product wherein the polypeptide is used.

The present invention relates to a method for producing a whey protein hydrolysate, the method comprising subjecting a whey protein-containing starting material having (a) a lipid content of less than 1 mass % and/or (b) a lactose content of less than 1 mass % to hydrolysis treatment. According to the present invention, a whey protein hydrolysate having excellent flavor with reduced odor is produced by reducing the problems involving rough taste, bitterness, or an unpleasant odor caused by hydrolysis of whey proteins. It is also possible to produce a whey protein hydrolysate that is not easily discolored, and that is prevented from being degraded in quality during the production process and storage thereof.

The present invention refers to a method for obtaining dehydrated food with a high content of hydrolyzed proteins from fish stickwater; for this purpose, the insoluble solids and fat traces are separated the stickwater, which then undergoes a process of demineralization by electrodialysis, in order to then adjust its temperature and pH to proceed with the enzymatic hydrolysis that allows to fractionate the protein, which is then concentrated and spray dried, and then the dried product is finally conveniently packaged.

Abstract: A method of preparing a protein hydrolysate using extrusion technology is provided. An intact protein source and a protease component are added to an extruder and mixed therein to form a slurry including a protein hydrolysate having a degree of hydrolysis of 5% to 30%. The slurry has a total protein content of at least 30% based on the weight of solids in the slurry. A protein hydrolysate accordingly produced is also claimed.

The present invention concerns novel protein hydrolysates of marine origin and methods of producing the same. The invention also concerns the use of such hydrolysates as palatants and as a food flavoring agents.
