  • Patent number: 4985270
    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.

  • Patent number: 4847409
    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.
