摘要:
Lactoferrin hydrolyzates, having a decomposition rate between 6%-20% as measured by formol titration, for use as an antibacterial agent, and which have remarkably more potent activity than unhydrolyzed lactoferrin; and lactoferrin hydrolyzates, having a decomposition rate between 4-50% as measured by formol titration, for use as a tyrosinase inhibition agent, are obtainable by conventional methods for hydrolysis with acids or enzymes, and are stable to heating.

摘要:
A method for treatment of a matter which contains moisturized or liquified lactoferrin which has been isolated from mammalian milk, processed mammalian milk and by-products in mammalian milk-processing, without losing the physiological activities of lactoferrin, which comprises adjusting pH of said moisturized or liquefied lactoferrin contained in said matter within an acidic range between 2.0 and 6.0 both inclusive by adding acid or aqueous solution of acid when the pH of said moisturized or liquefied lactoferrin is out of said pH range, and heating said matter in the range from 60.degree. C. to 130.degree. C. for a span of time which may assure 60% or more of undenaturization rate of lactoferrin.
摘要:
Bioactive agents, having growth-promoting activity upon Bifidobacteria, consisting of one or more lactoferrin-compounds selected from the group consisting of bovine lactoferrin, bovine apolactoferrin and bovine Fe-lactoferrin, which can be used as it is as agents to promote proliferation of Bifidobacteria both in vivo and in vitro, and as additives to prepare compositions, materials and products to afford growth-promoting activity thereto, and to improve survivability of Bifidobacteria, if contained therein.
摘要:
Bioactive agents consisting of one or more lactoferrin-compounds selected from the group consisting of Zn-, Cu- and Mn-lactoferrin and having selective biological activities, i.e. growth-inhibitory activity against certain harmful microorganisms on one hand and growth-promoting activity upon certain useful microorganisms on the other hand; as well as compositions, products or materials therefor comprising the bioactive agents consisting of one or more lactoferrin-compounds selected from the group; and a method for treating materials, which are edible for human beings or animals or which are applicable to a portion of body of human beings or animals, with the bioactive agents consisting of one or more lactoferrin-compounds selected from the group consisting of Zn-, Cu- and Mn-lactoferrin or the compositions comprising the bioactive agent consisting of one or more lactoferrin-compounds selected from the group consisting of Zn-, Cu- and Mn-lactoferrin as an effective component.
摘要:
A method for producing a peptide mixture from a starting protein by (1) adding at least one protease to an aqueous solution of at least one starting protein to hydrolyse the starting protein, (2) measuring the amount of a free amino acid selected from the group consisting of lysine, phenylalanine, leucine and arginine produced during the hydrolysis of the starting protein, (3) calculating the amount of the free amino acid with respect to the total amount of amino acid contained in the starting protein, and (4) terminating the hydrolysis when the calculated amount of the free amino acid with respect to the total amount of the amino acid contained in the starting protein falls within a predetermined range. The inventive method provides a starting protein hydrolysate of uniform and consistent quality.

摘要:
A method of manufacturing a low-phosphorus whey, the method including subjecting a raw whey liquid to a demineralization treatment using a nanofiltration method to obtain a low-chloride whey liquid in which the chloride content has been reduced to not more than 30 mmol per 100 g of solids, and passing the low-chloride whey liquid through an ion exchange resin to obtain an ion-exchanged whey liquid having a reduced phosphorus content, wherein the ion exchange resin is composed of an anion exchange resin, and at least an anion exchange resin in chloride form is used as the anion exchange resin. The method of manufacturing a low-phosphorus whey can reduce the phosphorus content within the whey while suppressing reduction in the calcium and magnesium content.
