Abstract
A method of preparing a gelled product from an ungelled aqueous hydrolyzed collagen, such as gelatin or glue, concentrate containing 10-60 weight percent hydrolyzed collagen and a lyotropic agent is disclosed. The concentrate has a hydrolyzed collagen-to-lyotropic agent weight ratio of 1:0 of 1:0.1 to about 1:4.5, a pH value of 2.5-7 and gels at less than 20.degree. C. On dilution with water to a hydrolyzed collagen concentration of about 2 weight percent while substantially maintaining the pH value of the concentrate, the diluted composition gels at a temperature above that of the concentrate. Specific concentrates, food products, industrial applications and methods for using the concentrates are disclosed.
Claims13
A method for coating a substrate with a hydrolyzed collagen gel comprising the steps of:
- providing first volume of an aqueous hydrolyzed collagen concentrate comprising water, from about 10 to about 60 weight percent hydrolyzed collagen and a non-acid lyotropic agent, the weight ratio of hydrolyzed collagen-to-non-acid lyotropic agent being about 1:0.1 to about 1:4.5, said concentrate having a gel-set temperature of less than about 20.degree. C. and a pH value between about 2.5 and about 7;
- diluting said first volume of hydrolyzed collagen concentrate to from about 2 to about 300 times said first volume to a hydrolyzed collagen concentration of between about 0.5 and about 25 weight percent to provide a diluted composition having a gel-set temperature higher than that of said hydrolyzed collagen concentrate;
- applying said diluted composition, prior to gelation, to contact the surface of a substrate and form a coating thereon;
- and
- maintaining said applied, diluted composition in contact with said substrate surface at a temperature below the gel-set temperature of said diluted composition for a time sufficient to form a gel on said surface.
A method for controlling the escape of dust from a dust laden surface comprising the steps of:
- providing an aqueous hydrolyzed collagen concentrate comprising water, from about 10 to about 40 weight percent hydrolyzed collagen and a lyotropic agent, the weight ratio of hydrolyzed collagen-to-lyotropic agent being about 1:0.3 to about 1:4.5, said concentrate having a gel-set temperature of less than about 0.degree. C. and a pH value between about 4 and about 6;
- diluting said hydrolyzed collagen concentrate to a hydrolyzed collagen concentration of between about 0.5 and about 3.5 weight percent to provie a diluted composition having a gel-set temperature higher than that of said hydrolyzed collagen concentrate;
- applying said diluted composition, prior to gelation, to contact the surface of a dust laden substrate;
- and
- maintaining said applied, diluted composition in contact with said substrate surface at a temperature below the gel-set temperature of said diluted composition for a time sufficient to form a gel on said surface.
