  • Publication number: 20150140185
    Abstract: The present invention relates to a novel solvent-free process for the production of protein-, starch- and fiber-enriched fractions or fractions rich in specific compounds from pulses, grains, oilseeds, and dried fruits. Unlike conventional wet processes, this dry process preserves the natural configuration and structure of separated components. This process employs a tribo-electrostatic technique to selectively charge proteins, carbohydrates, fibers, and other components in pulses, grains, oilseeds, and dried fruits and separates them based on the magnitude and type of their charge.

  • Patent number: 6569341
    Abstract: A method of raising the concentration of a liquid mixture utilizes osmotic distillation to transfer a volatile liquid component from the mixture in contact with one side of a nonporous, preferably high free volume, gas permeable membrane to a strip solution in contact with the other side of the membrane. Due to its nonporous nature the gas permeable membrane resists penetration and wetting by oily components that may be present in the feed mixture. Similarly, occlusion of the membrane by solids is resisted. Preferably, an amorphous copolymer of perfluoro-2,2-dimethyl-1,3-dioxole is useful for the gas permeable membrane. Osmotic distillation utilizing such high free volume, nonporous gas permeable membranes can concentrate difficult liquid mixtures such as pulpy fruit juices and especially, limonene-containing juices, for example, orange juice. The process can be operated at high flux for long durations between membrane cleanings.

  • Patent number: 4844923
    Abstract: A process for deproteinizing milk products, such as milk or whey, is disclosed. In connection with the steps of acidifying and heating the milk product, the milk product is also demineralized at least to some extent prior to the precipitation of the serum proteins. By means of this demineralization, a destabilization of the proteins is attained, allowing these serum proteins to be precipitated by acidification and heating. The milk products may be deproteinized in dependence upon the degree of demineralization, and the amount of serum protein can be reduced to approximately 0.2% or less. Also, partial or complete demineralization of milk proucts permits a lower acid proportion in the product by maintaining acidification at the same pH value. Reduced acidification time is also noted.

  • Patent number: 4803089
    Abstract: The invention relates to a process for the decationization of by-products of milk, particularly whey for cheesemaking, by ion exchange, comprising passing the by-product in liquid form successively through a weak cationic resin and then through a strong cationic resin and then regenerating the resins by passing an acid successively through the strong cationic resin and then through the weak cationic resin.This process enables the strong cationic resin to be utilized to 90% of its capacity and from 30 to 40% of regeneration reactant to be saved. The product obtained serves as an intermediate in the production of lacto-proteins and demineralized lactoserum products suitable for human and animal nutrition.

  • Patent number: 4786597
    Abstract: Catalytic chemical and biochemical conversion reactions are carried out in a novel compartmentalized catalytic reactor which enables the energy-efficient coupling of the conversion reaction with various energy-consuming post-conversion operations. The catalytic reactor is compartmentalized by means of a multilayer composite membrane comprising a catalytic membrane layer and one or more permselective membrane layers. The arrangement and properties of the membrane layers are such as to enable the free energy change of the conversion reaction to be utilized as the required energy source for effecting various post-conversion operations, including product separation, recovery and enrichment, and second-stage catalytic conversions with unfavorable reaction equilibria.

  • Patent number: 4781809
    Abstract: Processes and apparatus are disclosed for recovering free organic acids from aqueous solutions in which they occur at least in part as free acid together with other organic matter comprising:(a) passing said solution through a de-acidifying chamber (compartment, cell, space) in an electrodialysis ("ED") apparatus, said de-acidifying chamber defined on each face thereof by membranes substantially permeable to anions, said membranes separated from each other by turbulence promoting spacers, such ED apparatus also comprising an organic acid receiving chamber juxtaposed to one face of said de-acidifying chamber;(b) passing a direct electric current (which may include alternating current components) through said ED apparatus in a direction to cause anions of said organic acid and hydronium cations to migrate into said organic acid receiving chamber; and(c) recovering from said organic acid receiving chamber a solution comprising free organic acid.

  • Patent number: 4497836
    Abstract: 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.

  • Patent number: 4374714
    Abstract: The susceptibility to color and flavor loss of liquid containing comestibles due to oxidative deterioration during storage is reduced by placing the comestible in the cathode compartment of an electrochemical cell in which the compartments of the cell containing the anode and cathode are separated by a cation permeable membrane and the anode compartment contains a highly dissociatable, non-oxidizable inorganic acid electrolyte, and thereafter subjecting the comestible to a high density current for a short period of time sufficient to generate hydrogen at the cathode to remove oxygen from the comestible but insufficient to effect a substantial chemical change in the comestible. The deoxidized comestible is then stored in a hermetically sealed container in which air is substantially absent.

  • Patent number: 4317841
    Abstract: A process for reducing the acidity of a coffee extract is described in which the coffee extract undergoes electrodialysis. The non-cathodic extract is collected, contacted with subdivided chitosan and, after removal of the chitosan, is mixed with at least a part of cathodic extract to provide a deacidified coffee extract.

  • Patent number: 4202909
    Abstract: A high yield of relatively pure lactose and salt products are produced from a permeate resulting from ultrafiltration of whey by precipitating calcium and citrate salts from the permeate without substantial precipitation of phosphate salts by concentrating the permeate to a solids content of about 40 to 45% and holding at about 180.degree. to 200.degree. F. for 30 to 90 minutes, removing precipitated solids from the permeate and then further concentrating the permeate and crystallizing and removing lactose.

  • Patent number: 4160713
    Abstract: In a process for electro-dialysis which comprises passing an electrolyte through dilution chambers and concentration chambers formed between a large number of alternately counterposed anion exchange membranes and cation exchange membranes, and applying an electric potential to a pair of electrodes provided at both ends of a plurality of these chambers, thereby migrating ions in the electrolyte through the membranes and effecting dilution or concentration of the electrolyte, such a volumic rate of air bubbles is introduced to the lower parts of the dilution chambers as to make the thickness of a diffusion layer formed by concentration polarization near the ion exchange membranes in the dilution chambers smaller than when air bubbles are not introduced thereto, and make the resistance between the electrodes smaller than when the air bubbles are not introduced thereto. Superficial air velocity of air bubbles introduced into the dilution chambers is preferably 1-4 cm/sec.

  • Patent number: T990005
    Abstract: An improved process for the electrodialysis treatment of liquid whey is disclosed in which the raw whey is first subjected to an ultra high temperature environment of about between 130.degree. C. to 150.degree. C. for a period of approximately two seconds to sterilize the whey. The sterilized whey is then subjected to cooling and then to electrodialysis to effect a substantial reduction in ash content.
