1. A method of using a composition having an oil-in-water dispersion to enhance a physical, chemical, nutritional and/or sensory property of a food, comprising:

  • applying, into or onto the food, a substantially surfactant-free composition that remains stable when diluted at least up to 1000 fold with an aqueous fluid, the composition comprising;

    a first oil-in-water dispersion having an oil phase comprising one or more hydrophobic particles that have a net negative charge that is −

    30 mV or lower of a hydrophobic agent that is edible and 90% wt. or more non-polar suspended in an aqueous phase comprising either water or water and one or more water-miscible substances;

    wherein the particles of the hydrophobic agent in the first oil-in-water dispersion have an average particle size of about 100 nm to about 999 nm in diameter, at least 85 wt % of the particles of the hydrophobic agent in the first oil-in-water dispersion have a particle size that is ±

    200 nm of the average particle size, and the particles have a polydispersity of 0.25 or less;

    wherein the net negative charge imparted to the hydrophobic particles causes the particles of the hydrophobic agent to repel each other with a force of repulsion;

    wherein the force of repulsion sufficiently exceeds the force of coalescence among the particles of the hydrophobic agent, thereby enhancing stability of the first oil-in-water dispersion by resisting aggregation of the particles of the hydrophobic agent;

    wherein small average particle size, low polydispersity, and force of repulsion of the particles of the hydrophobic agent in the first oil-in-water dispersion increase an extent of penetration of the first oil-in-water dispersion throughout a water phase of a substrate of the food; and

    thereby producing a bloom effect distributing the particles of the hydrophobic agent uniformly throughout the water phase of the substrate that enhances a physical, chemical, nutritional and/or sensory property of the food.
