摘要:
A milk or other dairy product, capable of minimising the onset of disease such as coronary heart disease or enhancing the immune response is derived from animals which are substantially free of the beta -casein A allele. Bulk milk can be produced by testing for and culling cows who test positive for the beta -casein A allele, or by producing immunoglobulins and other immune response proteins, in cow's milk from animals not possessing the beta -casein A allele, or other commercial milk pruducing animals, to this allele, to counteract the immunosuppressant substances present that are produced from it, in commercial milking cows such as Holsteins, together with its blending with non-treated milk or the recovery of such immunoproteins.

The invention concerns a method for isolation of proteins from whey or soy and for modification of the proteins isolated, according to which method: a) whey or soy or a concentrate thereof is brought into contact with a reagent that forms sulfite ions in order to sulfonate the protein, and optionally b) the sulfonated protein is precipitated at an acid pH, and c) the sulfonated protein or the precipitated and soluble sulfonated protein is recovered and optionally processed further.
摘要:
A whey protein with a phosphorus content reduced to 0.15 mg or less per gram of the protein, a process for the production thereof, a hydrolyzate of a highly purified low-phosphorus whey protein, and a process for the production thereof. The low-phosphorus whey protein is produced by adjusting the pH of a whey protein solution to 4 or below and bringing the solution into contact with a cation-exchange resin and an anion-exchange resin successively to thereby reduce the phosphorus content to 0.15 mg or less per gram of the protein. The hydrolyzate of the highly pure low-phosphorus whey protein is obtained by hydrolyzing the low-phosphorus whey protein with protease.
摘要:
A method of producing immunoglobulin-rich milk, including colostrum, in mammalian mothers, is described. The method comprises administration of an effective daily dosage of a preparation containing at least one type of xanthophylls, such as astaxanthin, to said mothers, e.g. cows. Immunoglobulin-rich milk, including colostrum, produced according to the method and immunoglobulin concentrates derived from such milk, including colostrum, are also disclosed. Theses products may be used as nutrient for mammals, and as raw material for diagnostics, human and veterinary medicines, dermatologic preparations and cosmetics industry.
摘要:
An apparatus for the continuous production of soft protein foods wherein the liquid protein source remains enclosed, passing through a heat exchanger followed by one or more holding tubes, passing into coagulation tubes. The product exits onto a perforated conveyor belt, permitting drainage of a liquid by-product. This invention also includes processes for producing various soft protein foods such as acid-curd cheeses, whey cheeses, soyfood, and casein.
摘要:
The invention concerns a simple ion-exchanging industrial process which consists in treating a liquid lactic raw material containing glycomacropeptide in the presence of a weak anionic resin to obtain an improved protein product useful in food processing and said glycomacropeptide which is selectively adsorbed on the resin, then eluted in said resin. Before being treated with resin, the liquid raw material is decationized so that its pH has a value between 1 and 4.5.
摘要:
The invention relates to a method for the isolation of total milk protein or whey protein content of milk, in a concentrated and functional form. The protein product is suitable for use in food formulations and dietetic products, where it performs as well as sodium caseinate, but with the added benefit of having more bland flavour characteristics. The product has enhanced nutritional properties and better flavour characteristics when compared to sodium caseinate. The process involves the acidification of skimmed milk or whey to a pH below the isoelectric point, followed by heating to at least 50 °C at the acidic pH.
摘要:
The invention provides a process for preparing a plurality of modified milk growth factors which process includes: providing a milk product extract including a plurality of milk growth factors having basic to approximately neutral isoelectric points and a source of acid; subjecting the milk product extract to transient acidification utilising the acid source; and isolating a plurality of modified milk growth factors from the transiently acidified milk product extract. Also provided are growth promoting compositions, cell culture compositions, and pharmaceutical or veterinary compositions for the treatment of surface wounds, gastrointestinal injuries, diseases or ulcers, each including a plurality of modified milk growth factors having isoelectric points above approximately 6.0 and molecular weights in the range of approximately 5000 to 30.000, the milk growth factors being modified by transient acidification.
摘要:
A whey-protein dominant baby food including hydrolysate food with a reduced threonine content is prepared. This food can be obtained by adding glycomacropeptide free or glycomacropeptide-reduced whey powder and/or whey protein concentrate as whey proteins usually used in the production of baby milk food.
摘要:
A process for encapsulating solid particles within a protein which comprises contacting a protein dispersion containing the solid particles with a polysaccharide in an aqueous medium at a pH above the isoelectric point of the protein to produce a mixture forming two phases, one of which is a concentrated heavier, lower phase comprising the solid particles encapsulated within the protein and the other of which is a diluted, lighter upper phase relatively rich in polysaccharide, and separating the concentrated, heavier lower phase to produce the solid particles encapsulated within the protein.
