  • Patent number: 7070822
    Abstract: The present invention is directed toward a free flowing powdered blend of a polysaccharide and a crystalline polyol for use as an edible adhesive for particulate materials such as seasonings and flavorings. The powdered adhesive blend can easily be mixed with seasonings or flavorings and will melt during a heating process to a sticky viscose liquid capable of adhering seasoning particles to the food substrate. The blends of the present invention have the benefits of being easy to prepare, use and store as they will stay a free flowing powder under most ambient conditions.

  • Patent number: 6261376
    Abstract: Thermally-inhibited, pregelatinized non-granular starches and flours are prepared by pregelatinizing the starch or flour and thermally inhibiting the starch or flour by dehydrating the starch or flour to anhydrous or substantially anhydrous and then heat treating the dehydrated starch. The pregelatinization may be carried out prior to or after the thermal inhibition using known methods which disrupt the granular structure such by drum drying or jet cooking and spray-drying. Preferably the starch or flour is adjusted to a pH above 7.0 prior to the thermal inhibition. The starch may be dehydrated by heating the starch in a suitable heating apparatus, by extracting the water from the starch using a solvent such as ethanol, or by freeze drying the starch. Preferably the starch or flour is treated with a solvent to remove proteins and/or lipids and thus prevent off flavors.

  • Patent number: 6231675
    Abstract: Thermally-inhibited starches and flours which are functionally equivalent to chemically-crosslinked starches are prepared by a process which comprises the steps of dehydrating a granular starch or flour to anhydrous or substantially anhydrous (<1% moisture) and heat treating the dehydrated starch or flour for a time and at a temperature sufficient to inhibit the starch, (e.g., 120-180° C. for up to 20 hours). Preferably the pH of the starch is adjusted to neutral or greater (e.g., pH 8-9.5) prior to the dehydration. The dehydration may be a thermal dehydration carried out simultaneously with the heat treatment or a non-thermal dehydration carried out by extraction with a solvent (e.g., ethanol) or by freeze drying.

  • Patent number: 6221420
    Abstract: A thermally-inhibited granular starch or flour is used as an ingredient in various foods. The thermally-inhibited starches are functionally equivalent to chemically cross-linked starches. The stashes or flours are prepared by dehydrating the starch or flour to anhydrous or substantially anhydrous (<1% moisture), preferably at a neutral or basic pH, and heat treating the dehydrated starch or flour for a time sufficient to inhibit the starch to the desired degree. The dehydration may be carried out by heating the starch, extracting the starch with a solvent, or freeze drying the starch. The starch may be pregelatinized prior to or after thermal inhibition using known methods which do not substantially rupture the starch granules.
