Abstract
Disclosed are novel compositions containing the egg yolk protein phosvitin or peptide fragments thereof. The compositions are substantially free of mineral ions chelated to the phosvitin protein or peptide fragments thereof. The compositions may be used in the formulation of products, including food products, personal care products, or pharmaceutical products, for example, to preserve the products.
Claims24
A method for formulating a product comprising:
- (i) providing a composition comprising phosvitin or peptide fragments thereof, wherein the phosvitin or peptide fragments thereof are substantially free of mineral ions chelated thereto;
- and
- (ii) formulating an effective preservative amount of the composition with additional ingredients suitable for formulating the product, to thereby form the product.

A product comprising:
- (i) an effective preservative amount of a composition comprising phosvitin or peptide fragments thereof, wherein the phosvitin or peptide fragments thereof are substantially free of mineral ions chelated thereto;
- and
- (ii) additional ingredients suitable for formulating the product.
27-45. (canceled)
A preservative formulation comprising phosvitin or peptide fragments thereof substantially free of mineral ions chelated thereto, together with a diluent, a carrier, or auxiliary agent, the mineral ions selected from the group consisting of calcium ions (Ca2+), iron ions (Fe2+), zinc ions (Zn2+), and manganese ions (Mn2+), wherein the phosvitin or peptide fragments thereof comprise less than about 148 ppm calcium ions (Ca2+), less than about 3.2 ppm iron ions (Fe2+), less than 2.3 ppm zinc ions (Zn2+), and less than about 0.033 ppm manganese ions (Mn2+) chelated thereto.
