During the forcing of the protein substance through the conduit, the method comprises feeding a fat-like substance into one or more further inlets (11) of the conduit for being combined with the food substance for yielding a marbling in the stream of the food product. For feeding the fat-like substance, the method comprises controlling a flow rate of the fat-like substance in the one or more further inlets, such that the marbling in the stream of the food product varies along a direction of the stream.

The present document relates to a protein structuring module for use in a food product manufacturing arrangement. The protein structuring module comprises one or more conduits between an inlet section and an outlet section, each conduit having an inlet at the inlet section for receiving a protein constituent and an outlet at the outlet section for providing a structured food substance including a structured protein material. The one or more conduits are configured for establishing a shear stress in the protein constituent for unfolding and/or aligning molecules in the protein constituent, such as to form the structured food substance. Furthermore, the protein structuring module comprises a chamber between the inlet section and the outlet section, and the protein structuring module further comprises one or more inserts configured for being inserted in the chamber for forming an insert bundle in the chamber of the protein structuring module. The one or more conduits are formed by gaps between the inserts. The document further relates to a food product manufacturing arrangement, a protein heating module, and a method of manufacturing the protein structuring module.

The invention relates to an acoustic sensing system, comprising a sensing fiber [2] located in an environment [3], an interrogator module [4] connected to the sensing fiber for interrogating the sensing fiber using an incident light [I], and a detection module [5',5''] connected to the sensing fiber for detecting light reflected by the sensing fiber illuminated by the incident light. The system further comprises a high power optical pulse light source [7] connected to the sensing fiber for injecting a high power optical pulse therein.

A hydrogen internal combustion engine (100) comprises one or more combustion units (10). Each combustion unit (10) includes a combustion chamber (11) configured to receive a mixture of hydrogen (H2) and oxygen containing gas (O2). An intake channel (12c) with an intake mechanism (12v) allows the oxygen containing gas to enter the combustion chamber (11). A compression mechanism (13) compresses the chamber volume, after which a fuel injector (14) injects hydrogen under pressure into the compressed volume. Combustion (CB) of the compressed hydrogen-oxygen mixture causes the chamber volume to expand, driving the compression mechanism (13). An exhaust channel (15c) with an exhaust mechanism (15v) allows discharge of the resulting combustion product (H2O). A catalytic ignition assembly (18) with catalytic material (C) promotes ignition (IG) of the compressed hydrogen-oxygen mixture to initiate combustion. This configuration may enable autoignition of hydrogen without requiring conventional ignition systems like spark plugs or pilot fuel.
