A stable and non-separable composition comprised of starch and a water-immiscible material can be prepared in the absence of external emulsifying or dispersing agents by thoroughly solubilizing an aqueous dispersion of the starch at elevated temperatures and incorporating the water-immiscible material into the non-retrograded starch under conditions of high turbulence. The resulting dispersions form soft gels that can be easily converted to pourable fluids by the application of heat. Upon drying, these dispersions yield solid compositions that are easily redispersed in water to form smooth, stable dispersions. These compositions are useful as thickening agents, suspending agents, waterproof coating materials, adhesives, fat substitutes, and seed coatings. They are receptive to the addition of a variety of other water-immiscible materials, such as volatile and essential oils, food flavorants, medicinals, waxes, agricultural chemicals, and the like.
A method of preparing a composition characterized by a uniform and stable distribution of water-immiscible material throughout a continuous starch phase, the method comprising the following steps:
A composition comprising droplets of a water-immiscible material stably and substantially uniformly distributed in a continuous starch phase in the absence of an external emulsifier, wherein said starch phase consists essentially of completely disrupted starch granules and said droplets are surrounded by a boundary layer separating them from the starch phase.
