Coagulation solution for causing coagulation of a collagen
View Patent ↗Described is a coagulation solution suitable for causing coagulation of a collagen-containing casing of a co-extruded food product. This coagulation solution comprises a highly soluble inorganic salt. The pH of the coagulation solution is adjusted using a buffer solution. Also described is a method for coagulating a collagen-containing of a co-extruded food product. This method comprises the step of bringing the collagen casing into contact with a coagulation solution. The coagulation solution herein comprises a solution as described above.
1. Coagulation solution suitable for causing coagulation of a collagen-containing casing of a co-extruded food product, characterized in that the coagulation solution comprises a coagulation sufficient amount of a highly soluble inorganic phosphate salt and a buffer solution to adjust the pH of the coagulation solution to the isoelectric point of collagen; wherein the pH of the coagulation solution is adjusted to be between 5.5 and 6.0.
2. Coagulation solution as claimed in claim 1 , characterized in that the buffer solution for an inorganic dipotassium phosphate salt contains a weak acid, for instance citric acid, lactic acid or acetic acid, which is within the presence of an organic salt.
3. Coagulation solution as claimed in claim 1 , characterized in that the buffer solution for an inorganic sodium phosphate salt contains a base, for instance sodium hydroxide, which is supported by the presence of an organic salt.
4. Coagulation solution as claimed in claim 1 , characterized in that the highly soluble inorganic salt comprises a sodium phosphate or a potassium phosphate.
5. Coagulation solution as claimed in claim 4 , characterized in that the highly soluble inorganic salt comprises monosodium phosphate or dipotassium phosphate.
6. Coagulation solution as claimed in claim 1 , characterized in that the coagulation solution also comprises a highly soluble organic salt.
7. Coagulation solution as claimed in claim 6 , characterized in that the highly soluble organic salt is chosen from the group of lactate, citrate and acetate compounds.
8. Coagulation solution as claimed in claim 7 , characterized in that the highly soluble organic salt comprises a sodium salt.
9. Coagulation solution as claimed in claim 1 , characterized in that the coagulation solution also comprises a carbohydrate compound.
10. Coagulation solution as claimed in claim 9 , characterized in that the carbohydrate compound comprises glucose syrup and/or maltodextrin.
11. Coagulation solution as claimed in claim 1 , characterized in that the coagulation solution comprises a cross-linking compound.
