Abstract

Abstract A fibrous milk protein product having a high tensile elongation (115 to 380%) and an excellent stability to hot water cooking (tolerant to treatment in hot water of 135 DEG C. for 4 minutes) which is produced by forming the starting milk protein into a fibrous composition and then treating the fibrous composition in an aqueous solution containing at least one of sodium, potassium and calcium salts and also an aldehyde type crosslinking agent having a ratio of molecular weight (M) to number of aldehyde groups (n) of 120 to 360 (e.g. lactose) at a pH of 2.5 to 6.5 and at 100 DEG to 140 DEG C. for 20 minutes to 3 hours.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 150 words
A process for producing a fibrous milk protein product having a high tensile elongation and stability to hot water cooking, which comprises forming a starting milk protein into a fibrous composition, and contacting the fibrous composition with an aqueous solution containing at least one salt selected from the group consisting of a sodium salt, a potassium salt and a calcium salt in a cationic concentration of 1 gram equivalent/liter or more and a compound containing an aldehyde group and having a ratio of molecular weight (M) to number of aldehyde groups in one molecule (n) of 120 to 360, said aldehyde compound being present in the solution in an amount of 5 to 200 g/liter, the aqueous solution having a pH value of 2.5 to 6.5, said fibrous composition being maintained in contact with said solution at a temperature of 100 to 140° C. for 20 minutes to 3 hours.
Claim 2
Dependent Claim 150 words
A process for producing a fibrous milk protein product having a high tensile elongation and stability to hot water cooking, which comprises forming a starting milk protein into a fibrous composition, and contacting the fibrous composition with an aqueous solution containing at least one salt selected from the group consisting of a sodium salt, a potassium salt and a calcium salt in a cationic concentration of 1 gram equivalent/liter or more and a compound containing an aldehyde group and having a ratio of molecular weight (M) to number of aldehyde groups in one molecule (n) of 120 to 360, said aldehyde compound being present in the solution in an amount of 5 to 200 g/liter, the aqueous solution having a pH value of 2.5 to 6.5, said fibrous composition being maintained in contact with said solution at a temperature of 100 to 140° C. for 20 minutes to 3 hours.
Claim 3
Dependent Claim 32 words
A process according to claim 1, wherein the concentration of total cations is 3 gram equivalent/liter or more and the compound containing aldehyde group has the ratio (M/n) of 180 to 360.
Claim 4
Dependent Claim 28 words
A process according to claim 1, wherein the aldehyde compound is a reducing saccharide or its derivative or a natural product containing the reducing saccharide or its derivative.
Claim 5
Dependent Claim 53 words
A process according to claim 3, wherein the aldehyde compound is a member selected from the group consisting of glycerose, erythrose, xylose, arabinose, ribose, glucose, fructose, galactose, mannose, rhamnose, fucose, maltose, lactose and uronic acids, phosphates, sulfates, fatty acid esters and condensates of these saccharides with a ratio (M/n) of 120 to 360.
Claim 6
Dependent Claim 19 words
A process according to claim 4, wherein the aldehyde is derived from an oxidate of glycerine monofatty acid ester.
Claim 7
Dependent Claim 33 words
A process according to claim 3, wherein the aldehyde compound is derived from a member selected from the group consisting of a skim milk, cheese whey, casein whey and a concentrated product thereof.
Claim 8
Dependent Claim 22 words
A process according to claim 1 or 2, wherein the fibrous composition is treated at a temperature of 104 to 140° C.
