    Abstract: Case 78109 COLD-WATER-DISPERSIBLE LECITHIN CONCENTRATES Cold-water-dispersible lecithin concentrates are prepared by a homogeneous blend of lecithin and certain nonionic emulsifiers (e.g., polyoxyethylene mono- and diglycerides and polyoxyethylene derivatives of partial fatty acid esters and hexitol anhydrides). The concentrates readily disperse into cold water (e.g., under 5.degree.C.) over a broad concentration range (e.g., 0.05-30%) to form low-viscosity and stable lecithin in water emulsions. Concentrates containing polyoxyethylene mono- and/or diglycerides are particularly effective emulsifiers for the lecithin concentrate.

    Abstract: A method of recovering a high-grade lecithin and solvents from an oil-bearing full miscella which also contains lecithin and which results from an oilseed ternary solvent extraction process. The method may include a first step of phase separation of the oil-bearing miscella containing lecithin and the ternary solvents into a polar and a non-polar phase, and a second step of azeotropic distillation of the non-polar phase to recover a portion of the solvents, and to remove substantially all the water from the residual crude oil, thereby keeping the lecithin in solution. A commercial grade lecithin having good water dispersibility is subsequently recovered from the residual crude oil, and a small amount of highly water dispersible lecithin may be recovered from the polar phase by atmospheric distillation. In another embodiment, when the full miscella containing crude oil ternary solvent and lecithin resulting from the above ternary solvent extraction is initially subjected to azeotropic distillation to recover solvent therefrom and remove substantially all the water, a highly water dispersible lecithin having a high choline chloride content is obtained. Premature degumming of this highly water dispersible lecithin is avoided by maintaining the solvent rations above certain minimums. The ternary solvents for the oilseed extraction include a lipophilic hydrocarbon, such as hexane; a water miscible lower alcohol, such as ethanol; and a minor amount of water. The recovery method is energy efficient, because the boiling temperature of the ternary azeotrope is lower than any other combination of the three solvents.

    Abstract: LOW-VISCOSITY, HIGH-NSI, HEAT-GELLING SOY ISOLATES The present invention provides high NSI dry vegetable protein isolates which may be effectively utilized to replace egg albumin and/or miIk caseinates in food recipes. The isolates are characterized as having an NSI of at least 90, substantially free from vegetable protein hydrolyzates, capable of forming insoluble heat-set gels and having aqueous Brookfield viscosities substantially lower than those which are obtained from conventional undigested vegetable protein hydrolyzates. The relatively neutral pH extraction conditions in the presence of sulfurous ions, coupled with its recovery without chemically or enzymatically hydrolyzing the protein constituents affords an effective method for manufacturing these unique isolate products. The isolates may be used to directly replace either casein or egg albumin in a wide variety of food recipes.

    Abstract: 7S AND 11S VEGETABLE PROTEIN FRACTIONATION AND ISOLATION Aqueous mixtures of water-soluble 7S and 11S proteins are effectively fractionated and isolated by precipitating the 11S protein at a pH 5.8-6.3 in the presence of carefully controlled concentrations of water-soluble salts and sulfurous ions. The enriched 7S whey may then be adjusted to a pH 5.3-5.8 to precipitate substantially all of the remaining water-soluble 11S protein from the whey an enriched 7S fraction may then be recovered from the whey. The fractionation is capable of producing either 11S or 7S isolates which respectively contain less than 5% 7S or 11S protein impurities.

    Abstract: By enzymatically modifying vegetable glycoprotein isolates with an acid proteinase such as pepsin, the glycoproteins may be converted to a vegetable isolate useful as egg albumin replacement or whip-stabilizing agent. The enzymatic modification partially hydrolyzes the glycoproteins and compositionally alters the glycoprotein subunit and aggregate structure. The enzymatic alteration produces a glycoprotein aggregate comprised of a plurality of subunits having saliently different physical and functional properties from that of the vegetable protein precursor source materials. The enzymatically modified vegetable isolates are capable of forming firm, white, opaque heat-set gels similar to those of egg albumin. The enzymatically modified glycoproteins are compatible with salt-containing recipes and functionally useful over a broad pH range.

    Abstract: Case 81033 Phytate-containing proteinaceous materials are treated with trivalent aluminum to alter the physical, chemical and metabolic functional and nutritional values of the protein. Protein derived from phytate-containing seed materials treated with trivalent aluminum possess improved solvent solubility, protease digestability, reduced thermophiles and trypsin inhibition reduction, low viscosity, trace mineral bioavailability, etc. without requiring phytate or phytic acid removal. The aluminum treatment may be conducted at numerous protein manufacturing stages with a wide variety of different materials. Phytate-containing proteins may be effectively extracted at acid pH levels in the presence of trivalent without sacrificing recoverable protein yields.

    Abstract: Case 80007 ENZYMATICALLY TREATED PHOSPHATIDES It has been discovered that phosphatides contain certain carbohydrates which adversely affect their functional properties. By hydrolyzing such carbohydrates with an effective amount of carbohydrase, the physical and functional properties of such phosphatides are significantly improved. In the manufacture of lecithin, wet gums enzymatically treated with carbohydrases dehydrate more rapidly into a low moisture leclthin product. The enzymatic treatment also fluidizes phosphatide compositions and stabilizes the compositions against solidification.
