Abstract
A process for isolating a collagen-derived protein fraction from a marine invertebrate, comprising the steps of: 1) preparing a collagen-containing portion of said marine invertebrate for extraction; 2) treating the collagen-containing portion with a weak acid solution in order to solubilise a collagen-derived protein fraction; and 3) collecting the collagen-derived protein fraction.

A process for isolating a collagen-derived protein fraction from a marine invertebrate, comprising the steps of:
- 1) preparing a collagen-containing portion of said marine invertebrate for extraction;
- 2) treating the collagen-containing portion with a weak acid solution in order to solubilise a collagen-derived protein fraction;
- and
- 3) collecting the collagen-derived protein fraction.
A process for obtaining native collagen, comprising the steps of:
- 1) providing a marine invertebrate from which collagen may be extracted;
- 2) preparing a collagen-containing portion of the marine invertebrate for extraction;
- 3) treating the collagen-containing portion with a weak acid solution in order to solubilise a collagen fraction;
- and
- 4) collecting the native collagen.
A process of de-pigmenting a marine invertebrate having undesirable pigmentation, comprising the steps of:
- 1) isolating the food portion of the marine invertebrate;
- and
- 2) contacting the food portion with a weak acid solution in order to extract the pigment.
An isolated polypeptide, said polypeptide being the α1 chain of type I abalone collagen, said polypeptide having a molecular weight of approximately 123.9 kD.
An isolated polypeptide, said polypeptide being the α2 chain of type I abalone collagen, said polypeptide having a molecular weight of approximately 110.6 kD.
Native collagen isolated from abalone.
