Patent number: 7070822Abstract: 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.Type: GrantFiled: December 20, 2002Date of Patent: July 4, 2006Assignee: National Starch and Chemical Investment Holding CorporationInventors: Yong-Cheng Shi, Yayun Liu, Robert L.

Patent number: 6261376Abstract: 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.Type: GrantFiled: November 10, 1999Date of Patent: July 17, 2001Assignee: National Starch and Chemical Investment Holding CorporationInventors: Roger Jeffcoat, Chung-Wai Chiu, Manish B.
