Abstract: The present invention relates to an enzymatic method of preparing a fermented plant-based product. More specifically, the method involves treating a plant-based liquid substrate having a plant protein content of 1% (w/w) or higher with one or more proteases and a microorganism: and allowing the treated plant-based substrate to ferment to produce the fermented plant-based product. Preferably, the protease is B. amyloliquefaciens neutral metalloprotease (bacillolysin, P7L) and lactic acid bacteria are used for fermentation. At low degree of hydrolysis viscosity of the protease-treated plant protein surprisingly increased, potentially due to the formation of peptides with hydrophobic N-terminal moieties, which could form a gel due to hydrophobic interactions. At higher degree of hydrolysis viscosity was—as expected—reduced.

Abstract: A process for separating particles of different sizes comprising projecting a stream of particles into a fluid medium; allowing the particles to develop differing trajectories in the fluid medium; providing at least two separate collection areas for different average size particles from the stream of particles; and collecting particles along said different trajectories.
