The invention provides oil-in-water emulsions comprising recombinant collagen-like polymer in an amount sufficient to act as stabiliser of the emulsion. The polymer is especially a polypeptide which is free of helix structure, has an isoelectric point at least 0.5 pH units removed from the pH of the oil-in-water emulsion. Furthermore, amphiphilic recombinant collagen-like polymers are provided for use in oil-in-water emulsions. The amphiphilic polymers are polar at one end as a result of a relative abundance of polar amino acids, and apolar at the other end as a result of a relative abundance of apolar amino acids,
An oil-in-water emulsion having a composition including, in an amount sufficient to stabilize the emulsion, a collagen-like recombinant peptide, the collagen-like recombinant peptide comprising at least one GXY domain having a length of at least 5 consecutive GXY triplets wherein X and Y each represents an amino acid and wherein at least 20% of the amino acids of the collagen-like recombinant peptide are present in the form of consecutive GXY triplets.
An amphiphilic recombinant collagen-like peptide comprising at least one GXY domain having a length of at least 5 consecutive GXY triplets wherein X and Y each represents an amino acid and wherein at least 20% of the amino acids of the collagen-like recombinant peptide are present in the form of consecutive GXY triplets and having an amphiphilic structure, with at least one part of the molecule being polar due to the presence of a sufficient number of polar amino acid residues to render that part polar and another part being apolar due to the presence of a sufficient number of apolar amino acid residues to render that part apolar, wherein the average transfer free energy per amino acid of at least one part polar is at least 0.3 kcal/mole lower than the average transfer free energy per amino acid of at least one apolar part.
