Claim 2:
3. A method of preparing multi-component pectin fibres, the method comprising:
adding pectin and a sacrificial proteinaceous material to water to form a dope; and
forcing the dope through a spinneret while inducing a voltage between the spinneret and a collector plate in a temperature controlled environment,
wherein adding pectin and the sacrificial proteinaceous material to water to form the dope comprises:
adding the sacrificial proteinaceous material to heated water;
agitating the sacrificial proteinaceous material and the heated water using a mixer to form a mixture in which the sacrificial proteinaceous material is fully dissolved;
adding pectin to the mixture to form a solution;
agitating the solution until the pectin is fully dissolved; and
cooling the solution to obtain the dope such that the dope is at room temperature before forcing the dope through the spinneret, and
wherein the multi-component pectin fibres comprise:
a first fibre component consisting of pectin and gelatin;
a second fibre component consisting of gelatin, pectin, and carboxymethyl cellulose fibre; and
a third fibre component consisting of gelatin, pectin, and alginate.
