摘要:
The method of the present invention for separating and purifying a cationic protein is performed by using an electrodialysis apparatus. The electrodialysis apparatus used herein includes an electrodialysis bath having an anode and a cathode. The electrodialysis bath includes an anode compartment, a raw material loading compartment, a concentration compartment, and a cathode compartment in this order from the anode side. The anode compartment and the raw material loading compartment are divided from each other by a porous membrane made of a polymer having an anion exchange group, the raw material loading compartment and the concentration compartment are divided from each other by a porous membrane made of a polymer having a cation exchange group, and the concentration compartment and the cathode compartment are divided from each other by a microporous membrane. The method of the present invention includes the steps of, in this electrodialysis apparatus, (1) loading a cationic protein-containing aqueous solution into the raw material loading compartment and loading an electrolytic solution into the anode compartment, the concentration compartment, and the cathode compartment, (2) applying a current to the electrodialysis apparatus, and (3) collecting a solution containing a cationic protein from the concentration compartment.

A process for removing oil from an agricultural substrate, including a dry grind corn. An ethanol solution with a concentration in the range of from about 90% to about 100% ethanol is mixed with the dry grind corn in a ratio of from about 10:1 to about 1:1 to form an extraction solution including the ethanol solution, oil, and corn solids. The extraction solution is separated into the corn solids and a filtrate, the filtrate including the ethanol solution and oil. The filtrate is membrane filtered, including nanofiltration, to restrain an oil concentrate from the filtrate and pass a permeate of the ethanol solution. The oil contained within the oil concentrate is purified.

The invention concerns a method for obtaining a highly enriched TGF-beta protein fraction in activated form, from a liquid solution rich in proteins said to be soluble in the aqueous phase of milk and/or of whey, said method comprising the following steps; a) adjusting soluble proteins purified at a concentration between 5 and 30 g/liter of solution; b) precipitating part of the whey proteins by acidic treatment of the solution thus obtained to a pH ranging between 4 and 5.5 and at a temperature ranging between 55° C. and 68° C.; c) carrying out a microfiltration of the treated solution by diafiltration, so as to obtain respectively a microfiltration retentate and a microfiltrate; d) recuperating the microfiltration retentate containing the protein fraction highly enriched in TGF-beta; e) drying the microfiltration retentate which has been subjected to diafiltration to obtain a powder highly enriched in TGF-beta.
摘要:
A corn product removal process for removing zein and/or oil from dry-milled corn. Oils and/or zein are extracted from corn using ethanol. Corn solids are separated from the ethanol, oil and zein mixture produced by extracting. Thereafter, the ethanol, oil and zein mixture is membrane filtered to restrain zein from the mixture and pass an oil and ethanol mixture. The zein and/or oil may be concentrated and purified.

Oil seed protein isolates, in particular canola protein isolate, having a decreased phytic acid content is prepared by a procedure in which extraction of phytic acid from oil seed meal is inhibited during extraction of protein from the oil seed meal.
摘要:
According to a first aspect there is a method for producing a protein-free product comprising free amino acids and short peptides, wherein raw protein materials are crushed and hydrolysed with endogenous enzymes and passed through different separation processes, including coagulation of protein residues, in order to obtain the desired product. The invention further comprises the product obtained and uses thereof. According to a second aspect, a protein product enriched with free amino acids and short peptides is produced, wherein the raw protein materials are ground and hydrolysed with endogenous enzymes, and wherein the hydrolysate undergoes various separation processes. The product obtained comprises proteins, short and long peptides, free amino acids and minerals and has a low fat content and salt content. According to a third aspect, hydrolysation of a protein-containing raw material and separation of amino acids/peptides is carried out, wherein the hydrolysation is effected by using the endogenous enzymes of the protein-containing raw material. The hydrolysate is passed through a membrane filter, wherein peptide/amino acids follow a permeate stream, whilst the active enzymes continuously break down any protein residues that are deposited on the membrane surface. The enzymes are passed together with retenate back to the hydrolysis. Furthermore, an amino acid and peptide product and an oil product are described and the use thereof is disclosed.

A system, processes, and milk-based food products made from the system and processes, in which cream is separated from milk to produce an ultra-low fat milk product. The milk product is microfiltered to produce a retentate that is ready to drink and is high in protein and has no or substantially no fat. The permeate from the microfiltration process is ultrafiltered to produce a retentate that is high in protein with few other solids. The permeate may be used to provide protein fortification to other food and beverage products, and is especially useful in its liquid form for such fortification.

Soy derived materials such as soy milk, soy flour, soy concentrates and soy protein isolates, are deflavored by adjusting the pH of an aqueous composition of such soy derived materials to about 9 to 12 to solubilize the soy proteins and to release the flavoring compounds and thereafter passing the pH-adjusted composition to an ultrafiltration membrane having a molecular weight cutoff up to about 50,000 Daltons under conditions at which the flavoring compounds pass through the membrane, leaving the retained soy material with improved flavor.
