Claims49
A method for producing a marine peptide product from a marine by-product derived from fish processing, the method comprising:
- filtering a marine by-product, wherein the marine by-product is (i) blue whiting or mackerel bloodwater, or (ii) one or more of fish skins, fish bone and gut waste from blue whiting or mackerel, using one or more filters selected from 3 kDa filter membrane and 10 kDa filter membrane, to obtain at least one retentate, a 3 kDa fraction and/or a 10 kDa fraction,
- wherein the marine peptide product is the obtained fraction(s).
A method for producing a marine peptide product from a mackerel by-product derived from fish processing, the method comprising:
- hydrolysing the mackerel by-product, which is one or more of fish skins, fish bone and gut waste, with one or more hydrolysis enzymes selected from alcalase and papain,
- using one or more filters selected from 3 kDa filter membrane and 10 kDa filter membrane, to obtain at least one retentate, a 3 kDa fraction and/or a 10 kDa fraction,
- wherein the marine peptide product is the obtained fraction(s).
A marine peptide product comprising one or more peptides selected from peptides comprising SEQUENCE ID NO. 1 to SEQUENCE ID NO. 64.
A marine peptide product comprising one or more peptides selected from peptides comprising SEQUENCE ID NO. 65 to SEQUENCE ID NO. 169.
A marine peptide product comprising one or more peptides selected from peptides comprising SEQUENCE ID NO. 170 to SEQUENCE ID NO. 188.
A marine peptide product comprising one or more peptides selected from peptides comprising SEQUENCE ID NO. 189 to SEQUENCE ID NO. 271 and SEQUENCE 363.
A marine peptide product comprising one or more peptides selected from peptides comprising SEQUENCE ID NO. 272 to SEQUENCE ID NO. 362.
A peptide comprising a sequence selected from SEQUENCE ID NO. 1 to SEQUENCE ID NO. 363, or an ACE-1 inhibitory variant thereof having 1 to 3 amino acid changes, wherein said the or each amino acid change is selected from an insertion deletion, addition, and substitution.
