  • Patent number: 5153020
    Abstract: A fat substitute is disclosed which comprises water-dispersible macrocolloid particles composed of carbohydrate materials which particles have a substantially spheroidal shape and a specific particle size distribution effective to impart the substantially smooth organoleptic character of an oil-and-water emulsion.
    Type: Grant
    Filed: March 28, 1991
    Date of Patent: October 6, 1992
    Assignee: The NutraSweet Company
    Inventors: Norman S. Singer, Hsien-Hsin Chang, Pamela Tang, John M. Dunn
  • Patent number: 5112956
    Abstract: The present invention relates to a method for the removal of lipids and cholesterol from protein materials comprising the steps of (a) treating the protein with an extraction mixture comprising a lower alcohol, water and an acid, in concentrations selected to extract cholesterol and lipids from the protein, and (b) removing the extraction mixture from the protein.
    Type: Grant

  • 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.
    Type: Grant

  • Patent number: 4911946
    Abstract: A fat substitute is disclosed which comprises water-dispersable macro-colloid particles having a substantially spheroidal shape and a particle size distribution effective to impart substantially smooth organoleptic character of an oil-and-water emulsion. The particles are composed of carbohydrate material.
    Type: Grant
    Filed: June 24, 1988
    Date of Patent: March 27, 1990
    Assignee: The Nutra Sweet Company
    Inventors: Norman S. Singer, Hsien-Hsin Chang, Pamela Tang, John M. Dunn
  • Patent number: 4283427
    Abstract: A microwave heating package, and a method of microwave heating. Both the package and the method employ a lossy chemical susceptor which upon continued exposure to microwave radiation becomes substantially microwave transparent, thus building into the system a unique maximum temperature shut off at the point at which the chemical susceptor becomes microwave transparent. The chemical susceptor is comprised of a combination of a solute, such as inorganic salts of Group IA and IIA, and a polar solvent for the solute, such as water. The chemical susceptor may be composed of a hydrated form of the inorganic salts. The package, method and chemical susceptor may be used for microwave heating of many products, including among others, food products.
