    PROTEIN DISPLACEMENT DURING CLASSIFICATION OF GLANDED COTTONSEED (1980)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 45 (1980), S. 0

    Notes: The effects of classification of glanded cottonseed flour on protein displacement were studied. Media were liquid (nonpolar solvent) and air. The fines and coarse fractions had different ratios of water-soluble functional and storage proteins than the starting material. The difference in protein distribution was reflected in the contents of essential amino acids of each fraction. Fines or “overs” fractions had lower amounts of some limiting essential amino acids such as lysine, threonine and leucine as compared with the coarse fraction. Degossypolised cottonseed flour therefore had lower protein quality than the starting material. Although the fines fractions have lower amounts of essential amino acids as compared with the coarse fractions, they did not differ in the type of proteins as shown by gel electrophoresis.

    Effect of Liquid Smoke on the Growth of Lactic Acid Starter Cultures used to Manufacture Fermented Sausage (1982)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: Fermented sausage was manufactured using a commercial lactic acid starter culture and varying levels of liquid smoke. Samples were taken during the 24 hr fermentation period and the lactic bacterial count, pH and titratable acidity determined. Final pH values, titratable acidity and lactic bacterial counts were not affected by recommended use levels of liquid smoke, although exponential growth was delayed. Growth studies in a broth medium containing liquid smoke suggest that liquid smoke has the potential for inhibiting the lactic starter cultures used to make fermented sausage.

    A Direct Hexane Extraction Process for Glanded Cottonseed (1982)
    Oxford, UK : Blackwell Publishing Ltd

    ISSN: 1750-3841

    Notes: A modified filter funnel apparatus was used to determine mass flow velocities for extraction of uncooked glanded cottonseed flakes, and the results were compared with a continuous pilot-plant-scale extractor. A mass velocity of 2,000 lb/hr/ft2 or higher (considered adequate for oilseed extraction) was obtained in all cases. Both the initial meat moisture before flaking and the flake moisture during extraction were found to affect the mass velocity. A meat moisture before flaking of less than 9% decreased the mass velocity, probably as a result of increased fines and thus smaller flake size. A high flake moisture (about 9%) during heated-hexane extraction caused a decrease in mass velocity compared to that of lower-moisture flakes. The correlation of filter-funnel mass velocity data to a continuous pilot-plant extractor confirmed that uncooked flakes can be satisfactorily extracted to yield low residual lipids by using a low solvent-to-flake ratio and ambient-temperature hexane solvent.

    HEAT-INDUCED TRANSITIONS IN THE PROTEIN-PROTEIN INTERACTION OF BOVINE NATURAL ACTOMYOSIN (1984)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food biochemistry 8 (1984), S. 0 
    Details
    ISSN: 1745-4514
    Source: Blackwell Publishing Journal Backfiles 1879-2005

    Notes: Protein-protein interaction of bovine natural actomyosin (NAM) was studied by means of optical density changes resulting from discrete particle formation in the temperature range of4°C to 70°C. From Arrhenius plots, the apparent heat of activation (ΔHa) at pH 5.5 (17.1 kcallmole) was significantly (P〈0.05) lower than activation energies in the pH range of 6.0 to 7.5. The lower Δ Ha resulted in initiation of protein-protein interaction at a temperature near 16°C at pH 5.5, whereas interaction did not proceed until the temperature approached 37°C at pH 6.0 and above. Derivative curves (dOD/dT) at pH 5.5 and 6.0 showed two distinct NAM thermal transition regions. Tm1 occurred at 43.0°C at pH 5.5 and 48.5°C at pH 6.0, with the 5.5°C difference possibly arising from effects of proton binding in altering protein conformation. Only a 1.5°C difference in Tm2 (56.0°C at pH 5.5 versus 57.5°C at pH 6.0) was found. Although the overall heat-mediated NAM aggregation (in dilute solution) was found to follow first order kinetics by two evaluation methods, the existence of two thermal transitions supports a two-step reaction mechanism proposed for the formation of protein gels (in higher concentration solutions).

    Notes: Abstract. We provide lower and upper bounds for the maximal number of facets of a d-dimensional 0/1-polytope, and for the maximal number of vertices that can appear in a two-dimensional projection (``shadow'') of such a polytope.

    Shelling Polyhedral 3-Balls and 4-Polytopes (1998)

    Notes: Abstract. There is a long history of constructions of nonshellable triangulations of three-dimensional (topological) balls. This paper gives a survey of these constructions, including Furch's 1924 construction using knotted curves, which also appears in Bing's 1962 survey of combinatorial approaches to the Poincaré conjecture, Newman's 1926 explicit example, and M. E. Rudin's 1958 nonshellable triangulation of a tetrahedron with only 14 vertices (all on the boundary) and 41 facets. Here an (extremely simple) new example is presented: a nonshellable simplicial three-dimensional ball with only 10 vertices and 21 facets. It is further shown that shellings of simplicial 3 -balls and 4 -polytopes can ``get stuck'': simplicial 4 -polytopes are not in general ``extendably shellable.'' Our constructions imply that a Delaunay triangulation algorithm of Beichl and Sullivan, which proceeds along a shelling of a Delaunay triangulation, can get stuck in the three-dimensional version: for example, this may happen if the shelling follows a knotted curve.

    Hilbert Bases, Unimodular Triangulations, and Binary Covers of Rational Polyhedral Cones (1999)

    Notes: Abstract. We present a hierarchy of covering properties of rational convex cones with respect to the unimodular subcones spanned by the Hilbert basis. For two of the concepts from the hierarchy we derive characterizations: a description of partitions that leads to a natural integer programming formulation for the HILBERT PARTITION problem, and a characterization of ``binary covers'' that admits a linear algebra test over GF(2) for the existence of BINARY HILBERT COVERS. Implementation of our test leads to interesting new examples, among them: cones that have a HILBERT PARTITION but no REGULAR one; a four-dimensional cone with unimodular facets that has no HILBERT PARTITION; and two five-dimensional cones that do not have any BINARY HILBERT COVER.
