摘要:
The present invention relates to a method for improving the solubility of vegetable proteins. More specifically, the invention relates to methods for the solubilization of proteins in vegetable protein sources, which methods comprise treating the vegetable protein source with an efficient amount of one or more phytase enzymes, and treating the vegetable protein source with an efficient amount of one or more proteolytic enzymes. In another aspect, the invention provides animal feed additives comprising a phytase and one or more proteolytic enzymes.

A seasoning composition is prepared by preparing a koji and in the absence of added salt, hydrolyzing the koji in the presence of a culture of lactic acid bacteria at a temperature between 15.degree. C. and 60.degree. C. and at a pH of from 4.5 to 10 for a period of from 6 hours to 28 days, and the seasoning composition is obtained without preparing a moromi. Inoculation with the lactic acid bacteria culture is carried out either in the hydrolysis stage or in the koji preparation stage, and the hydrolysis may be carried out in two stages with the culture present during the first stage and so that the temperature of the first stage hydrolysis is between 20.degree. C. and 60.degree. C. and particularly between 25.degree. C. and 50.degree. C. and so that the second stage temperature is from 2.degree. C. up to 20.degree. C., and the second stage hydrolysis is carried out for at from 12 hours to 25 days and the first and second stage hydrolysis are carried out for a combined time of from 18 hours to 28 days.
摘要:
A method of manufacturing a protein gel. In the first step, a protein-containing solution is heated for sterilization. In the second step, the protein-containing solution is cooled, and an enzyme is added to the protein-containing solution. In the subsequent third step, the protein-containing solution and the enzyme are mixed while maintaining the temperature in the second step so as to obtain a mixture. In the fourth step, the mixture is aseptically filled in a food container. In the fifth step, the aseptically filled mixture is allowed to stand at ambient temperature, during which the enzyme denatures the protein in the protein-containing solution. Since the mixture is not required to be heated for denaturing the protein in the protein-containing solution, the energy consumed in the manufacturing process is reduced, thereby lowering the manufacturing costs.

A whey protein dominant baby food is prepared that may contain hydrolysed food with a reduced threonine content. This food can be obtained by adding glycomacropeptide-free or glycomacropeptide-reduced whey powder and/or whey protein concentrate as the whey proteins usually used in the production of milk baby food.
摘要:
Aminopeptidases originating from Aspergilli niger are disclosed, which can be produced in a fermentation broth or a liquid concentrate thereof substantially free of endoprotease. Such aminopeptidases may be advantageously employed in the food industry, e.g. in the preparation of bread doughs or cheese.
摘要:
A method for debittering and reducing the allergenic reactivity of protein hydrolysates is disclosed, which method includes the providing of an aqueous solution of a protein hydrolysate, feeding the solution into a bed of siloxane, and collecting a first portion of the solution exiting from the bed. The first portion contains either a non-bitter or bitter fraction. A second portion of the solution exiting from the bed can be collected which contains the opposite tasting fraction of the hydrolysate. Preferably the siloxane is selected from the group comprising octa-siloxane and octadecyl-siloxane. Preferably the hydrolysate has a molecular weight of less than 10,000, and is derived from the group of hydrolysates comprising casein, whey and soy. Additionally, the bed preferably is of a depth of between 2 to 4 times the bed diameter. A more hypoallergenic protein hydrolysate product produced in accordance with the method of the invention is also disclosed.
摘要:
A whey protein hydrolysate is described which is free of allergenics while preserving the structures susceptible of exerting anticipatory regulations to maximize the tolerance and protein metabolism, and mixtures thereof with casein and/or soy protein hydrolysates. Whey protein hydrolysates according to the invention have an amino acid composition comprising at least 2% by weight of tryptophan, less than 5% by weight of threonine, less than 2.8% by weight of methionine whereby 40 to 60% by weight of the amino acids are in the form of tetra- to decapeptides.
摘要:
A whey protein having a phosphorus content reduced to below 0.15 mg per gram of protein, a manufacturing method thereof, a low-phosphorus hydrolysate highly purified having a low phosphorus content. The method comprises the steps of adjusting pH of the solution containing the whey protein to below 4, and contacting the solution with a cation exchange resin, sequentially contacting the solution with an anion exchange resin, thereby reducing the phosphorus content to below 0.15 mg per gram of protein, and the highly purified low-phosphorus whey protein hydrolysate of the present invention is available by hydrolyzing the above-mentioned low-phosphorus whey protein with proteases.
摘要:
The method for restructuration of raw meat for production of restructured raw meat by addition to the meat of transglutaminase comprises the further addition of phosphate (optional) and sodium chloride, with a subsequent temperature treatment. Hereby the cohesion and hardness of the restructured raw meat is improved, and it can be sold as a refrigerated meat product.
摘要:
There is disclosed a process for producing a soybean protein material which comprises the steps of: hydrolyzing soybean protein with a protease in an aqueous system to an extent of hydrolysis of 5 to 20; if necessary, emulsifying an oil-and-fat ingredient with soybean protein in an amount of 5 to 50 parts by weight per 100 parts by weight of the soybean protein before or after the hydrolysis step; drying the resultant emulsified mixture; and, optionally, a step for dispersing an emulsifier being provided at any stage after emulsification with the oil-and-fat ingredient. The soybean protein material thus obtained has taste, color and water-dispersibility suitable for a pickling solution having a high concentration and thick drinking food such as soup with less foaming property.
