  • Publication number: 20210106014
    Abstract: The present invention relates to novel synergistic compositions comprising known “clean-label” antimicrobial substances as well as processes for stabilizing food substances against typical food borne spoilage microorganisms and/or pathogens. It is a further object of the invention to provide novel combinations of “clean-label” antimicrobials which may be employed in such a process.

  • Patent number: 9376351
    Abstract: Processes for preparing water soluble and oil soluble antioxidant compositions extracted together from Labiatae herbs in a single extraction using an alcohol and water solvent, followed by a simple, yet effective purification step that allows the separation of the water soluble antioxidative fractions containing mainly rosmarinic acid from antioxidative fractions containing mainly carnosic acid and carnosol, without cumbersome acid/base partitioning steps.

  • Publication number: 20120046369
    Abstract: The present invention relates to compositions with effective metal chelating activity and utility as natural antioxidants in food, beverages, nutritional supplements and cosmetics. The compositions of the present invention may be prepared by enzymatically hydrolyzing hypoallergenic protein isolates derived from vegetables, for example yellow pea (Pisum sativum), and/or grains using specific enzymes.

  • Publication number: 20100197812
    Abstract: The present invention provides metal-chelating or sequestering antioxidant compositions, derived from edible herbs, spices, fruits, vegetables and/or grains, useful for incorporating into foods, beverages, nutritional supplements and cosmetics for the purpose of enhancing the stability of said food, beverage or cosmetic. This invention provides processes for preparing these antioxidant, stability-enhancing compositions.

  • Patent number: 7740205
    Abstract: An auxiliary wing and flap assembly for an aircraft which is to be extendable from a retracted position to a deployed position. Relative to the chord of the wing, the split flap is located directly adjacent the trailing edge of the wing with the auxiliary wing assembly being located at approximately the mid length of the chord of the wing. A split flap assembly extends approximately one-half the length of the aircraft wing with the auxiliary wing assembly extending the total length of the aircraft wing. The split flap is extendable to assume approximately a sixty degree angle relative to the bottom surface of the aircraft wing while the auxiliary wing assembly is extendible to assume a maximum of ninety degree angle relative to the bottom surface of the aircraft wing. The chord length of the split flap is equal to approximately 0.15 of the chord length of the aircraft wing while the auxiliary wing assembly has an airfoil-shaped member that has a chord length of approximately 0.

  • Patent number: 5865738
    Abstract: A method and apparatus for evaluating the viability of a tissue of interest, particularly that presents as dead but may be merely stunned or hibernating with reduced or no obvious activity, such as contractility. Dynamic measurement of oxidative metabolism or other metaboic function permits distinguishing between different stages of compromised tissue such as myocardium. Measurements can be made using near-infrared illumination and detection coupled with infusion of one or more metabolic substrates to the region of interest to evaluate whether a metabolic pathway cascade or a trans-membrane ionic potential are intact and thereby provide an indication of the viability of the cell. One preferred instrument includes a catheter having a tip configured to be positioned adjacent to the tissue to be monitored. Optical fibers extend through the catheter to transmit a monitoring light beam from the tip into the tissue, and to receive a cytochrome-redox-response-dependent light beam from the tissue.

  • Patent number: 4881703
    Abstract: A flap assembly attached to the undersurface of a wing of an aircraft. The size of the flap has been precisely designed in view of the size of the wing of the aircraft and also precisely located relative to the wing of the aircraft so that the flap can be used as an air brake to substantially slow the speed of the aircraft when landing without loss of lift thereby utilizing substantially less runway during landing. Also, the flap assembly can be deployed to increase lift for the purpose of utilizing substantially less runway during take-off.
