1. A method of preparing multi-component pectin fibres, the method comprising:
adding pectin and a sacrificial proteinaceous material to water to form a dope;
forcing the dope through a spinneret;
crosslinking the dope with a source of ions to form fibres; and
drying the fibres,
wherein adding pectin and the sacrificial proteinaceous material to water to form the dope comprises:
adding the sacrificial proteinaceous material to heated water;
mixing the sacrificial proteinaceous material and the heated water while heating the sacrificial proteinaceous material and the heated water to form a mixture;
adding pectin to the mixture while heating the mixture to form a homogeneous solution;
applying a vacuum to the homogeneous solution to remove excess air; and
cooling the homogeneous 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.
