The present invention relates to the use of a defoaming agent for preventing pellet morphology of thermophilic fungi when grown at acidic pH in chemically defined media. The invention pertains to processes for producing a fermentation product, wherein the thermophilic fungus, e.g. a Rhizomucor species, is grown in submerged culture at acidic pH in a chemically defined medium and wherein the strain is cultured in the presence of a defoaming agent. The defoaming agent can be a vegetable oil such as olive or sun flower oil and the fermentation product can be single cell protein in the form of biomass of the thermophilic fungus for use as a dietary source of protein.

A process for producing a protein product from plants and yeasts comprises providing a thin stillage or a thin stillage concentrate; separating a protein concentrate from the thin stillage; diluting the protein concentrate to a dry substance content of at most 15 wt.%, tempering the diluted protein concentrate to at least 60° C., and adjusting the pH of the diluted and tempered protein concentrate to alkaline; cooling the processed protein concentrate and subsequently separating a liquid phase; adjusting the pH of the separated liquid phase to an acidic pH, and then separating a solid phase; and dispersing the solid phase in a solvent and subsequently separating a product phase, wherein the product phase comprises the protein product from plants and yeasts.

Methods and systems for producing improved hemp seed products, such as proteins and oils are provided.

This disclosure describes methods to separate solids from liquids in a production facility. A process separates components in the process stream by using a mechanical device to separate the solids from the liquids based on a density difference. The process produces the liquids and solids, which may be further processed to create valuable animal feed products.

The invention relates to a peptide isolate isolated from a biomass of protein-rich microalgae, characterized in that it comprises: soluble peptides with a molecular weight of between 1 and 20 kDa, a protein content expressed as N.6.25 of more than 95%, essentially arginine and glutamic acid.

The invention relates to a method for fractionating the components of a biomass of protein-rich microalgae of the genus Chlorella, characterized in that it comprises the following steps: providing a microalgal biomass produced by fermentation, optionally, washing the biomass so as to eliminate the interstitial soluble compounds, thermal permeabilization of the biomass at a temperature of between 50 and 150° C., preferably 100 and 150° C., for a duration of between 10 seconds and 5 minutes, preferably for a duration of between 5 seconds and 1 minute, separation between the biomass thus permeabilized and the soluble fraction by a centrifugation technique, more particularly multistage centrifugation, optionally, recovery and clarification of the soluble fraction obtained in this way by microfiltration so as to remove residual insoluble substances therefrom, separation of the preceding soluble fraction by precipitation, so as to obtain a peptide isolate and a peptide concentrate.

The present invention relates to a process for producing single cell protein, wherein a thermophilic fungus is grown a fermentable carbon-rich feedstock at a high temperature and at an acidic pH. This allows for a cost effective fermentation process that can to be run under non-sterile conditions and without additional cooling requirements. The process can be used to convert by-products or waste from agriculture or food production, or organic fractions of municipal solid waste into valuable single cell protein that can be applied as dietary source of protein or protein supplement in human food or animal feed.

Aquafeed, animal feed, and other food products, as well as nutritional and pharmaceutical compounds, chemicals and biomaterials are important commodities that can be produced at commercial scale by fermentation of microorganisms. The present invention provides a method for producing these valuable multi-carbon compounds from simple gas feedstocks, such as carbon dioxide, hydrogen and oxygen, by cultivating a consortium of microbial cells specially selected for this purpose in an aqueous culture medium. In addition to exploiting inexpensive feedstocks, such as waste industrial gas for this cultivation, the platform described herein also provides the advantage of removing carbon dioxide and other waste gases from industrial emissions, which would otherwise contribute to global climate change. Furthermore, the cultivation of a microbial consortium can provide highly nutritious components to a feed blend that might not be available from a monoculture.

The invention pertains to non-dairy proteins and nutritional compositions comprising non-dairy protein suitable for infant nutrition and a method of preparing a nutritional composition for infants or young children comprising non-dairy protein.

The present invention concerns a method for separation of (a) potato proteins and insoluble fibers from (b) first salts and phenolic and/or glycoalkaloid compounds in potato fruit juice or a derivative thereof, said method comprising the steps of: (i) providing a potato fruit juice or a derivative thereof, comprising potato proteins; and insoluble fibers; and one or more first salts; and phenolic and/or glycoalkaloid compounds; (ii) subjecting the potato fruit juice or the derivative thereof to a first cross-flow membrane filtration process resulting in a first retentate and a first permeate; and (iii) adding aqueous diafiltration liquid containing one or more salts to the first retentate and performing a second cross-flow membrane filtration as diafiltration, to create a second permeate containing at least a portion of said phenolic and/or glycoalkaloid compounds and salts and a second retentate comprising potato proteins, salts and insoluble fibers.

The present invention further concerns a potato fruit juice product comprising potato protein and insoluble fibers, such as a potato fruit juice product obtainable by the method according to the invention.
