Soymilk Process., Lawrence A. Johnson, Charles W. Deyoe, William J. Hoover Feb 1986

Soymilk Process., Lawrence A. Johnson, Charles W. Deyoe, William J. Hoover

Lawrence A. Johnson

Process for making a soybeanbased milk analog or soymilk and food products prepared therefrom. The process involves the comminuting of whole soybeans having the hulls thereon; forming a slurry of the comminuted soybeans; simultaneously initiating the inactivation of trypsin inhibitor and lipoxygenase without fixing protein bodies or substantially denaturing the soybean protein; confining the heated slurry until the trypsin inhibitor activity is reduced to a desired value; cooling the slurry; and separating the hulls from the slurry to recover the desired product. The resulting soymilk is an aqueous preparation of the soybean which exhibits minimal destruction of essential amino acids, …

Process For The Preparation Of Protein Isolates Of Improved Quality From Vegetable Protein Sources, Lawrence A. Johnson, Hwei-Mei Wen Aug 1984

Process For The Preparation Of Protein Isolates Of Improved Quality From Vegetable Protein Sources, Lawrence A. Johnson, Hwei-Mei Wen

Lawrence A. Johnson

Protein isolates are recovered from vegetable protein sources, such as sunflower meal, by extracting the meal with an alkali solution in the presence of an alkali metal borohydride, and then acid precipitating the resulting aqueous protein extract phase to produce a protein isolate. Typically, the alkali metal borohydride is employed in an amount of at least about 20 ppm, based on the combined weight of vegetable meal and alkali solution. Protein isolates produced by this process exhibit improved color, palatability and/or nutritional value, and comprise highly desirable additives for food products, animal foods, etc.

Protein isolates are recovered from vegetable protein sources, such as for example sunflower meal, by extracting the meal with an alkali solution in the presence of an alkali metal borohydride, and then acid precipitating the resulting aqueous protein extract phase to produce a protein isolate.

Removal Of Raw Peanut Flavor And Odor In Peanut Flour Processed By Direct Solvent Extraction1, Lawrence A. Johnson, J. T. Farnsworth, R. J. Garland, E. W. Lusas Jan 1979

Removal Of Raw Peanut Flavor And Odor In Peanut Flour Processed By Direct Solvent Extraction1, Lawrence A. Johnson, J. T. Farnsworth, R. J. Garland, E. W. Lusas

Lawrence A. Johnson

Peanut slices can be directly extracted with hexane yielding more soluble protein and better color than pre-press solvent extraction; however, flavor and odor are characterized as raw and “green beany”. The utilization of secondary extraction with hexane: ethanol azeotrope, hexane: methanol azeotrope and absolute ethanol subsequent to hexane extraction significantly improved flavor and odor characteristics of peanut flour. Hexane: propanol azeotrope did not significantly improve sensory evaluations. Hexane: ethanol azeotrope did not reduce soluble protein, yielding an NSI value of 95%. Hexane: methanol azeotrope and absolute ethanol slightly reduced NSI to 88% and 92% respectively. Color of peanut flour was …
