Abstract:
PROBLEM TO BE SOLVED: To solve the problem of the processing operations requiring significant time, typically on the order of at least one hour, to substantially increase the total dietary fiber.SOLUTION: High amylose flour may be processed by a short hydrothermal treatment to increase its total dietary fiber (TDF) content. This flour may be prepared by heating high amylose flour at a total water content of about 10 to 50 wt.% at a temperature of about 80 to 160°C, for about 0.5 to 15 minutes at a target temperature. This invention further relates to products which contain the high TDF flour, including food products.
Abstract:
The present invention is directed to a dry composition which allows delivery of active agents with good bioavailability. These compositions are prepared by emulsifying the active agent using liposome technology known in the art and then encapsulating with a modified starch. The modified starch is prepared by enzymatic hydrolysis of starch after the preparation of a starch derivative containing a hydrophobic group or both a hydrophobic and a hydrophilic group. The resultant composition is a dry powder with excellent bioavailability. Further, the composition has good load levels and stability.

PROBLEM TO BE SOLVED: To solve such a problem that prior attempts to treat starch in aqueous mixture processes with siliconate salts to develop water repellency (hydrophobicity) have resulted in undesirable properties and/or commercial disadvantages.SOLUTION: This invention relates to a single phase preparation of free flowing, hydrophobic starches which comprises a starch treated with a siliconate and an acid in a single phase process.
Abstract:
PROBLEM TO BE SOLVED: To prepare thermally-inhibited starches and flours by a process which comprises steps of dehydrating and heating granular starches or flours.SOLUTION: This invention relates to a process for preparation of thermally-inhibited non-pregelatinized granular starches includes: a step (a) of dehydrating the granular starch to be substantially anhydrous; and a step (b) of heat-treating the substantially anhydrous starch at 100°C or higher for a time sufficient to inhibit the starch.
