Abstract: An agglomerated modified cyclodextrin is made in a two drum dryer. The agglomerated product has low dusting problems and good dissolution in water. The particle size of the agglomerated product is 30 to 200 microns.

Abstract: Microbial growth in an aqueous cyclodextrin composition is inhibited by the addition of a small, polar base to the composition so as to provide a pH of 10-14 to the composition. The base includes sodium potassium, calcium, magnesium and ammonium hydroxides and carbonates as well as ethylamine, diethylamine and triethylamine. The composition is the resulting alkalaine, aqueous cyclodextrin solution. Adjusting the pH to the alkaline side shows superior antimicrobial action compared to conventional antimicrobial agents.

Abstract: The process for reducing sterols and free fatty acids from animal fat entails forming an oil-in-water emulsion using a mixing device such as a pump or an in-line mixer; and then pumping the emulsion through a conduit for a period of time. The emulsion is made from water, liquefied animal fat and cyclodextrin. The mixing device forms the emulsion in less than one minute; and the emulsion is pumped through the conduit for 5 to 60 minutes. During the time that the emulsion is moving through the conduit, the sterols and free fatty acids move from the fat phase to the water phase and form complexes with the cyclodextrin. These complexes are fairly stable and can be separated from the emulsion by centrifugation. The resulting fat has a reduced sterol and free fatty acid content.
