Abstract: It has now been found that emulsions having a discrete phase volume fraction of 60% to 67% with excellent stability may be prepared using at least one low molecular weight surfactant. Such emulsions have high oil loading and a small mean particle size of less than 0.2 microns. Further, such emulsions may be used in beverages without weighting agents.
Abstract: The method of forming a filter cake from a slurry comprising the steps of feeding the slurry into a filter housing, wherein the filter housing includes a plurality of vertical filter elements; pressing the slurry into the filter housing against the filter elements resulting in i) a filtrate passing through the filter elements and exiting out an exhaust port of the filter housing; ii) forming a solid cake on the filter elements; feeding a wash liquid into the filter housing while draining out the slurry by opening the slurry drain valve; closing the slurry drain valve and then continually feeding wash liquid through the cake and into the filter tube of the filter housing; stopping the feed of wash liquid; introducing a gas into the filter housing and draining out the wash liquid by opening a bottom drain valve; stopping the gas flow and opening a drain to exit most of the gas and remaining wash liquid; opening the bottom cake discharge valve; and back pulsing by a gas to break and to release the filter cake fr
Abstract: This invention is directed to a process for making a thermally inhibited polysaccharide by dehydrating a polysaccharide to substantially anhydrous or anhydrous conditions and thermally inhibiting the substantially anhydrous or anhydrous polysaccharide at a temperature of 100° C. or greater for a time sufficient to inhibit the polysaccharide in an oxygen enriched concentration of at least 6.5 moles/m3.

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.
