Abstract: Beverages and powdered beverage mixes fortified with ferric EDTA as an iron source are provided. The beverages and beverage mixes fortified with ferric EDTA according to this invention have superior iron bioavailability and excellent storage stability. The present invention also is directed to a method of using such ferric EDTA-fortified beverages to prevent or treat iron-deficiency anemia in individuals by administering the iron fortified beverage of the invention in an effective amount to an individual in need thereof.

Abstract: Methods for the sol-gel preparation of porous inorganic solids having highly uniform metal or metal oxide clusters embedded therein are provided. The porous solids are prepared by incorporating a metal ion-dendrimer complex into a gel and thermally decomposing the dendrimer to produce the solid. The invention further provides for novel inorganic solids exhibiting highly uniform porosity with metal or metal oxide clusters embedded therein.

Abstract: Methods for the preparation of mixed-valence manganese oxide compositions with quaternary ammonium ions are described. The compositions self-assemble into helices, rings, and strands without any imposed concentration gradient. These helices, rings, and strands, as well as films having the same composition, undergo rapid ion exchange to replace the quaternary ammonium ions with various metal ions. And the metal-ion-containing manganese oxide compositions so formed can be heat treated to form semi-conducting materials with high surface areas.

Abstract: The present invention generally relates to a process for hardening lipids, especially unsaturated lipids such as unsaturated fatty oils, by mixing and interacting lipids with polyamines such that the peak melting point of the resulting combination is higher than that of the lipid alone. In this way, the polyamine-treated unsaturated lipid can be converted into a solid or semi-solid state at a relatively lower temperature than the unsaturated lipid alone. The lipid and polyamine combination displays physical attributes that mimic the crystalline structures of saturated lipids and fats without the incurring the associated negative health implications of such saturated lipids and fats.

Abstract: The present invention provides halogenated calixpyrrole, calixpyridinopyrrole, and calixpyridine macrocycles having 4-12 pyrrolic rings with greater stability, enhanced anion and neutral molecule binding affinity, and different binding selectivites as compared to their nonhalogenated congeners as judged from 1H NMR, 19F NMR and fluorescence emission spectroscopic analyses.

Abstract: The present invention generally relates to inhibition of oxidation of polyunsaturated lipids by mixing the polyunsaturated lipids with a combination of polyamines providing a unique anti-oxidative effect on the polyunsaturated lipids. A especially advantageous combination of polyamines used in this regard includes spermine and a different linear aliphatic polyamine, such as spermidine, putrescine, or mixtures thereof. The rate of off-flavor development is significantly reduced in polyunsaturated lipids blended with such combinations of different polyamines. In addition, polyunsaturated lipid-containing materials and compositions can be stabilized using edible, non-toxic anti-oxidants based on such polyamine combinations. Omega-3 fatty acids and compositions containing them are especially well-suited for processing in this manner.
