Abstract: Non-fat and reduced fat whipped frozen dessert products wherein part or all of the milk fat, vegetable fat or oil ordinarily incorporated therein is replaced by a proteinaceous macrocolloid of, e.g., denatured whey protein particles or particles having a core of casein surrounded by a shell of denatured egg white protein. Illustrative embodiments include non-fat ice cream analog products having reduced calorie content, enhanced food value due to increased protein content, and possessing the physical and organoleptic character of full fat ice creams. The egg white protein/casein particles can be used also in sauces, dips, spreads, icing and cream pie fillings.

Abstract: A method for the isolation of a substantially pure L-isomer of an amino acid from its D,L racemic mixture does not require the use of a resolving agent, the formation of a derivative of the amino acid or additional enzymic reactions.The method is based upon the concept of the equal saturation point wherein the L-isomer can be separated from the D-isomer by precipitation of the L-isomer when the relative concentration of the D-isomer is less than 7.0% or by precipitation of the D,L racemate when the relative concentration is greater than 7.0%. Selective crystallization through seeding allows for further isolation of pure L-isomer when its relative concentration in solution is very low.
Abstract: Batch and continuous fluid processing devices including means for generating toroidal flow in a fluid to be processed, disposed in a container whose internal surface conformation corresponds to and is substantially defined by the external surface of the fluid when it is undergoing toroidal flow. In preferred forms, processing apparatus includes a blade mounted for axial rotation within a vessel having bowl shaped interior. The vessel is provided with a lid whose interior surface is shaped to conform to the upper surface of a fluid undergoing toroidal flow.
