摘要:
Bipolar membrane electrodialysis (BMED) was used to separate lipids from biological solutions. The lipids are separated from animal as well as vegetable solutions. Particularly, bipolar membrane precipitates high levels of lipids from a biological solution. The BMED single step process improves significantly lipid precipitation rates in several biological solutions of different natures.
摘要:
A quark matrix having improved taste characteristics is suggested, which is obtainable by (a) subjecting raw milk to heat treatment, separating the cream, (b) subjecting the skimmed milk such obtained to an ultrafiltration step, a microfiltration step, and/or a reverse osmosis step, producing a high-protein retentate R1 and a high-lactose permeate P1 in the process, (c) enriching the retentate with an amount of lactose which corresponds to the amount that had been separated in the ultrafiltration step as permeate before, (d) subjecting the enrichment product such obtained to heat treatment until denaturation sets in, (e) fermenting the denaturation product such obtained by adding starter cultures and rennet, and (f) adjusting the fermentation product such obtained to defined dry matter and protein contents.
摘要:
A method of dephospholipidating whey to separate the lipoproteins out of it and/or decrease its residual fat content by adding calcium to the whey, heating it and keeping it hot to aggregate the lipoproteins, and then centrifuging it. The pH of the whey is increased before it is heated by adding sodium-hydroxide solution, and the calcium is not added until after the whey is heated.
摘要:
A PROCESS FOR REMOVING DISSOLVED LIPID MATERIAL FROM AN AQUEOUS SOLUTION, PARTICULARLY FROM SOLUTIONS CONTAINING PROTEIN AND/OR LACTOSE, BY ADDING A DIVALENT METAL ION AND ADJUSTING THE PH TO A VALUE ABOVE 6 AT A TEMPERATURE BELOW 140*F., PRODUCING A LIPID-CONTAINING PRECIPITATE, AND SEPARATING THIS PRECIPITATE FROM THE SUPERNATE LIQUID.
摘要:
The present invention relates to processes for the treatment of dairy products and dairy process streams to produce lipids and substantially defatted protein streams. More specifically it relates to the use of near critical fluid extraction techniques to extract lipids from liquid dairy products and dairy process streams. Preferred solvents for use in the described near critical extraction techniques are ether based solvents that are partially miscible with water. A particularly preferred solvent for use in the invention is dimethyl ether.
摘要:
The present invention provides formulated milk compositions for infants analogous to human milk in which non-protein nitrogen components are abundant and the contents of .beta.-lactoglobulin and/or .alpha..sub.S casein are reduced.
摘要:
Whey from bovine milk is treated by a process involving passing whey through a diatomaceous earth filter, subjecting the filtered whey to ultrafiltration with water injection to form a whey protein concentrate and contacting the concentrate with a strongly acidic cationic exchange resin to produce a whey protein concentrate low in viable and total microbial count, low in mineral salt and having a pH in the range of 2.7 to 3.6.
摘要:
The invention is directed to precipitating whey lipids from a source material such as whey by adding a sufficient amount of chitosan to form a chitosan-lipid complex, and subsequently precipitating out the lipid from the resulting whey supernatant. The precipitate is removed either by filtration or centrifugation. The supernatant contains all the whey proteins which may then be recovered by conventional means such as ultrafiltration and spray drying. The lipids from the chitosan-lipid complex are then extracted
摘要:
A process for producing whey derived products suitable for use in infant food formulas from edible cheese whey. The cheese whey is subjected to ultrafiltration to produce a protein-rich retentate and a lactose-rich permeate. The permeate is then partially demineralized as by electrodialysis, and blended with the protein-rich retentate. Also products produced by the process.
