  • Stable aqueous solution of a polyene fungicide
    Publication number: 20090264379
    Abstract: The invention provides an aqueous composition comprising a dissolved polyene fungicide and a solubilizer, wherein at least 100 ppm of polyene fungicide is present as dissolved polyene fungicide. The aqueous compositions of the invention may further comprise a chelating and/or antioxidation agent. The compositions of the invention provide dissolved polyene fungicides in a more stable form. The present invention further provides uses of the compositions of the inventions and methods of making such compositions.

  • Targeting of active compounds to curd during cheese making
    Publication number: 20030185938
    Abstract: The present invention describes a hydrocolloid matrix in which an enzyme is entrapped. During the cheese making process this matrix can be added to milk. The enzymes are then mainly released from the matrix after that the separation of curd from the whey has taken place.

  • Preserving active fungicide in an aqueous solution
    Publication number: 20030055010
    Abstract: The present invention provides a method for preserving the activity of a polyene fungicide in an aqueous solution comprising providing the said aqueous solution with a chelating agent and/or an anti-oxidation agent, wherein the said chelating agent and the said anti-oxidation agent are the same agent or are different agents. Preferably, the aqueous solution further comprises a polymer. Preferably, the aqueous solution comprises a latex. The invention allows the selection of a wider range of polymer compositions for the preparation of a polymer emulsion comprising a polyene fungicide, wherein the activity of the said fungicide is at least in part stable and wherein the said emulsion is suited for the production of food coatings.

  • Longterm antimicrobial activity obtained by sustained release of hydrogen peroxide
    Patent number: 5747078
    Abstract: Methods for long-term preservation of food products using a lactoperoxidase system. Long-term preservation is achieved by controlled generation of hydrogen peroxide as a substrate for the lactoperoxidase system. Controlled production of hydrogen peroxide is achieved by generating the hydrogen peroxide enzymatically form a system wherein the substrate for the enzyme generating the hydrogen peroxide is immobilized or is generated in situ from a precursor.
