Soymilk Process, Lawrence A. Johnson, William J. Hoover, Charles W. Deyoe
Lawrence A. Johnson
This invention relates to a process for making a soybean-based 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 …

Process For The Preparation Of Protein Isolates Of Improved Quality From Vegetable Protein Sources Using Alkali Metal Borohydrides, Lawrence A. Johnson, Hwei-Mei Wen
Lawrence A. Johnson
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. 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
Extraction And Partial Characterization Of The Glycine Decarboxylase Multienzyme Complex From Pea Leaf Mitochondria, G. Sarojini, David J. Oliver
Extraction And Partial Characterization Of The Glycine Decarboxylase Multienzyme Complex From Pea Leaf Mitochondria, G. Sarojini, David J. Oliver
David J. Oliver
Glycine decarboxylase has been successfully solubilized from pea (Pisum sativum) leaf mitochondria as an acetone powder. The enzyme was dependent on added dithiothreitol and pyridoxal phosphate for maximal activity. The enzyme preparation could catalyze the exchange of CO2 into the carboxyl carbon of glycine, the reverse of the glycine decarboxylase reaction by converting serine, NH4+, and CO2 into glycine, and 14CO2 release from [1-14C]glycine. The half-maximal concentrations for the glycine-bicarbonate exchange reaction were 1.7 millimolar glycine, 16 millimolar NaH14CO2, and 0.006 millimolar pyridoxal phosphate. The enzyme (glycine-bicarbonate exchange reaction) was active in the assay conditions for 1 hour and could …
Genetic Divergence Within The Genus Liriodendron (Magnoliaceae), Jonathan F. Wendel, Clifford R. Parks, Norton G. Miller, Karen M. Mcdougal
Genetic Divergence Within The Genus Liriodendron (Magnoliaceae), Jonathan F. Wendel, Clifford R. Parks, Norton G. Miller, Karen M. Mcdougal
Jonathan F. Wendel
The genus Liriodendron L. consists of a southeast Asian-eastern North American disjunct species pair, but the genus had a much wider distribution in the Northern Hemisphere during the late Cretaceous and the Tertiary. Although generally similar in morphology, the two extant species are measurably different. In 1973 and 1977 they were hybridized, and interspecific heterosis was observed in the progeny. After seven years, the interspecific hybrids synthesized in 1973 had a significantly greater biomass than intraspecific hybrids of L. tulipifera. The growth rate of interspecific and intraspecific F2 seedlings was approximately equal. A preliminary survey of flavonoid extracts in L. …
