    Notes: The economics of processing the whey-type liquids from protein isolation from cottonseed flour to recover constituents of value and simultaneously remove a serious water pollution threat were investigated. Two processing systems were evaluated for use with wheys from two protein isolation procedures. System 1 consisted of ultrafiltration (UF) membrane processing followed by reverse osmosis membrane processing. System 2 consisted of UF processing followed by concentration of UF permeate by vacuum evaporation. Hypothetical whey plants evaluated were sized to process wheys from protein isolation plants producing 7,000,000 lb of storage protein isolate annually by either the Selective Precipitation Procedure (Process B) or the Two-Step Extraction Procedure (Process C). System 1 showed a slightly higher profitability than System 2. Process C whey processing proved to be more profitable than Process B whey processing. However, economically attractive annual rates of return on total capital invested before income taxes were obtained in each instance. These were 25.7% and 40.7% for System 1, Processes B and C, respectively.

    Notes: A root bioassay was used to determine the effect of various soils, and the chloride salts of Fe+++, Fe++, Al +++, Ca ++, K +, and Na+ on the activity of glyphosate (N-(phosphonomethyl)glycine]. Mineral soils significantly reduced the inhibitory effects of glyphosate on root growth. One muck soil inactivated glyphosate, but another muck soil and bentonite clay had little effect. Soils with the greatest inactivation capabilities had high concentrations of weak-acid-extractable iron. Glyphosate inactivation showed no correlation between cation exchange capacity and organic matter of the muck soils. FeCl3, FeCl2 and AlCl3, significantly reduced the activity of glyphosate, and, when allowed to stand in solution, combinations of FeCl3 and glyphosate formed a precipitate. CaCl2, KCl and NaCl did not inactivate glyphosate. Inactivation du glyphosate par divers sols et sels métalliques Un test biologique sur racines a été utilisé pour déterminer l'action de divers sols et de sels chlorés de Fe+++, Fe++, Al++, Ca++, K +, et Na+ sur I'activité du glyphosate N-(phosphono-méthyl) glycine. Les sols minéraux ont réduit significativement les effets inhibiteurs du glyphosate sur la croissance des racines. Un sol organique a inactivé le glyphosate, mais un autre sol organique, ainsi que la bentonite. n'ont eu que peu d'effet. Les sols qui ont présenté les plus grandes possibilités d'inactivation renfermaient des concentrations élevées dc fcr extractible par des acides faibles. II n'a pas été observé, en ce qui concerne l'inactivation du glyphosate, de corrélation entre la capaeité d'échange des cations et la teneure matiére organique des sols organiques. FeCl3, FeCl2, et AlCl3 ont significativement réduit l'activité du glyphosate et, lorsqu'ils ont été mis en présenceen solution, la combinaison de FeCl3 et du glyphosate a provoqué la formation d'un précipité, CaCl2, KCl et NaCl n'ont pas inactivé le glyphosate. Die Inaktivierung von Glyphosat durch verschiedene Böden und Metallsalze Die Wirkung verschiedener Bödden und der Chloride von Fe+++, Fe++, Al+++, Ca++, K+ und Na+ auf die Aktivität von Glyphosat N-(Phosphonomethyl)glycin wurde mit einem Wurzel-Biotest festgestellt. Mineralische Böden verringerten signifkant den Hemmeffekt von Glyphosat auf das Wurzelwachstum. Durch einen der organischen Böden wurde Glyphoat inaktiviert, ein anderer und das Tonmineral Bentonit, wirkten jedoch nur wenig inaktivierend. Böden mit der stärksten Inaktivierungsfähigkeit besassen hohe Konzentrationen an mit schwacher Säure extrahierbarem Eisen. Die Inaktivierung von Glyphosat war nicht mil der Kationen-Austauschkapazität und dem Gehalt der Böden an organischer Substanz korreliert Durch FeCl3, FeCl2 und AlCl3 wurde die Aktivitat von Glyphosat signifikant verringert. Wenn FeCl3 und Glyphosat in Lösung zusammengebracht wurden, bildete sich beim Stehenlassen dieser Kombination ein Niederschlag. CaCl2, KCl und NaCl wirkten auf Glyphosat nicht inaktivierend.

    Notes: Two alternative procedures have been developed for use in soy protein isolation with industrial membrane systems. These are (1) membrane processing soy extract at a higher pH (pH 11) and temperature (74°C) than previously done to produce a hydrolyzed product, (2) extracting soy protein with Ca(OH)2 (instead of NaOH) and membrane processing at pH 7. Hydrolyzed products were found to possess different physical and functional properties than previous products. Extracting soy protein with Ca(OH)2 produced a high-calcium, low-sodium product having unusually high nitrogen solubility over a wide pH range.

    Notes: A new approach to the production of protein isolates from oilseed flours with industrial ultrafiltration and reverse osmosis membranes previously demonstrated has been further optimized for use with soy flour. The effects on membrane performance of prefiltering the flour extract feed to different degrees and processing the feed at different pH levels were examined. A wide range of industrial membrane systems embodying several configurations was tested. Prefiltration of feed to less than 100μ proved to be unnecessary for most systems. Feed at pH 7.0 processed at high permeation rates and yielded products with NSI values in excess of 90.

    A STUDY OF FACTORS AFFECTING MEMBRANE PERFORMANCE DURING PROCESSING OF COTTONSEED PROTEIN EXTRACTS BY ULTRAFILTRATION (1977)

    Notes: Commercial membrane processing is an emerging new field. Consequently, there is still much to be learned about the process in general and about particular applications. Except for the dairy industry, little work has been reported in the literature relative to food processing. The purpose of the work reported was to determine which factors influence membrane performance when processing cottonseed protein extracts by ultrafiltration. Interest was centered on those factors affecting membrane flux and ways to improve and maintain the flux during processing. Maintenance of membrane flux is imperative for the process to be economically feasible on a commercial scale. Protein extracts were prepared at the Food Protein Research and Development Center (FPRDC) pilot plant from glandless cottonseed flour using a selective extraction procedure. Extracts were pasteurized and processed directly or frozen until used. The effects of pressure, feed velocity, temperature and feed composition on permeate flux were investigated using different membranes and membrane systems. It was found that permeate flux could be estimated as a function of Reynolds number. Viscosity, an important variable in Reynolds number, was found to be a function of total Kjeldahl nitrogen in the membrane feed solution and the relation was of the form v= aBN where v is kinematic viscosity and N is feed nitrogen content, and a and B are constants which are functions of temperature. The viscosity did not correlate as strongly with total organics (total solids minus ash) or carbohydrates as with total nitrogen.

    Notes: Summary An acid mine spoil in Southern Indiana was amended with lime (CaCO3) (0.0, 12.5, 25 and 39t/ha) and planted withElaegnus umbellata Thunb.,Alnus glutinosa Gaertn.,Robinia pseudoacacia L.,Robinia fertilis Ashe, ‘Arnot’,Myrica pensylvania Lois,Caragana arborescens L. andShepherdia argentea Nutt. Survival and soil data were collected periodically and plants were harvested 15 months after planting. Nodule and top dry weights were determined and acetylene reduction assays performed on the nodules. Addition of lime caused significant increases in pH, and 39 t/ha of lime were required to maintain a pH above 5.5. Survival of plant material was greatest at the highest lime addition, although response of individual species varied.Elaeagnus umbellata, R. pseudoacacia, R. fertilis ‘Arnot’, andA. glutinosa appeared more tolerant of the harsh conditions. OnlyC. arborescens showed a linear increase in top dry weight due to lime addition.Alnus glutinosa andS. argentea achieved statistically the same growth regardless of pH, andR. fertilis ‘Arnot’ andE. umbellata did not increase in top dry weight above an addition of 25 t/ha.Robinia pseudoacacia achieved maximum top dry weight at 25 t/ha, whereasM. pensylvanica growth declined with increasing pH. Nodule dry weights increased with increasing pH; however,S. argentea showed greater nodule dry weights at lower lime levels. Acetylene reduction rates increased with lime addition.Elaegnus umbellata did not respond above 25 t/ha lime, whereasA. glutinosa did not show an increase until this point.

    Notes: Abstract The smaller impact parameters that contribute to transfer reactions between heavy ions at high energies make them more sensitive to different types of optical potentials than is the case at lower energies. This may allow one to distinguish between potentials that otherwise generate similar elastic scattering cross sections within the limited angular region over which typical elastic data are available. We cite as evidence results for nucleon transfers induced by18O +28Si at 352 MeV which rule out surface transparent potentials.
