Abstract: Provided is a decarboxylating carboxylic acids of cannabinoids in hemp extract or hemp biomass in which the hemp extract or hemp biomass is heated to a temperature of 40° C. to 100° C. in the presence of one or more divalent or monovalent reagents.

Abstract: This invention describes natural hop products that are stable solutions of alpha-acids, as well as their preparation and their use for post-fermentation addition to beer for the purpose of improving the foam quality, as measured by foam stability and foam cling. Improvements in the stability (both physical and chemical) of the alpha-acids are described by incorporation of iso-alpha-acids and tetrahydroiso-alpha-acids as well as various brewery-acceptable co-solvents. The alpha-acids also improve the physical stability of the reduced iso-alpha-acids, including tetrahydroiso-alpha-acids.

Abstract: An improved flavoring composition and process for brewing malt beverages is disclosed. In one embodiment of the invention, the flavoring composition is formed from a high solids percent, room temperature stable, partially aqueous composition of a potassium salt of iso-?-acids. Such composition may be added to the wort kettle or else used as a post-fermentation additive, preferably after dilution with demineralized water. In another embodiment, the flavoring composition comprises a mixture containing reduced (rho-) iso-?-acids in alkali metal salts form, ?-acids and hop oil. This latter composition is useful as a substitute for normal kettle extract, hops or hop pellets, allowing easy preparation of beer that resists formation of unpleasant, “skunky” flavors but has otherwise similar flavor and physical properties.

Abstract: A process for the direct hydrogenation of hop resin acids in the absence of a liquid, organic solvent by reacting the hop resin acids with hydrogen in the presence of a noble metal catalyst at a temperature at which the resin acids are sufficiently fluid to allow easy mixing with the catalyst and suitably facilitate the hydrogenation reaction. Alternatively, the necessary fluidity may be achieved at relatively low temperature by subjecting the reactants to a high pressure of CO2 gas such that the quantity of this gas that dissolves into the resin is sufficient to substantially reduce its viscosity, the pressure of the CO2 gas being either less than the liquefaction pressure at temperatures below the critical temperature or less than that which would cause the density to exceed that at the critical point for temperatures above the critical temperature.

Abstract: The present invention is an extracted hop powder which has one or more hop acids blended back. This hop acid powder is flowable, does not cake-up and is more stable than hop powder that has not been extracted.

Abstract: A multi-actuator robotic device for performing knot-tying is provided herein. The device performs an automatic knot-tying to mimic human hand making a clove hitch knot using a sequence of coordinated string delivery and capturing actions and is particularly useful in the field of hop twining. In one example, the device uses four pneumatic actuators to perform nine coordinated knot-tying actions.

Abstract: A plant wash comprising a mixture of hop extract, a surfactant and water, is useful for increasing plant growth and fruit yield.

Abstract: A method for determining the combined activity of two or more ingredients by impregnating a carrier with one ingredient and bringing it into contact with target material to create a zone of inhibition, then adding a second ingredient to the target material and bringing the carrier into contact with it to create a second zone of inhibition. The zones are then compared.

Abstract: A process for inhibiting or preventing bacterial infections in animals by administering a mixture of a hop composition and an antibiotic selected from the group consisting of polymyxin, ciprofloxacin and tobramycin.

Abstract: The alkali metal salts form of ?-acids dissolved in propylene glycol is used to control microbial growth in food products, process streams and other applications, including in cosmetic formulations.

Abstract: A pharmacologically effective mixture of a polymyxin composition and a hop composition having a synergistic effect on bacteria greater than the antibacterial effect of those compositions administered separately.

Abstract: The combination of a polymyxin composition and a hop composition produces unexpected and synergistic activity against gram positive bacteria.

Abstract: The alkali metal salts form of ?-acids dissolved in propylene glycol is used to control microbial growth in food products, process streams and other applications, including in cosmetic formulations.

Abstract: A process for the direct hydrogenation of hop resin acids in the absence of a liquid, organic solvent by reacting the hop resin acids which hydrogen in the presence of a noble metal catalyst at a temperature at which the resin acids are sufficiently fluid to allow easy mixing with the catalyst and suitably facilitate the hydrogenation reaction. Alternatively, the necessary fluidity may be achieved at relatively low temperature by subjecting the reactants to a high pressure of CO2 gas such that the quantity of this gas that dissolves into the resin is sufficient to substantially reduce its viscosity. Particularly useful applications for the process are the conversion is iso-?-acids to tetrahydroiso-?-acids and rho-iso-?-acids into hexahydroiso-?-acids. The resinous products of the hydrogenation process may be readily converted to aqueous, alkaline solutions suitable for use in brewing beer.

Abstract: A new and distinct variety of hop, Humulus lupulus L., named “01046” is characterized by its exceptional cone yield, high percentage of alpha acids, and resistance to hop powdery mildew strains found in Washington. The new variety was cultivated as a result of a cross in 2000 at Golden Gate Roza Hop Ranches in Prosser, Wash., United States and has been asexually reproduced in Prosser, Wash., United States.

Abstract: A new and distinct variety of hop, Humulus lupulus L., named “APOLLO” is characterized by its exceptional high percentage of alpha acids, excellent storage stability of alpha acids, low CoH value for an alpha variety, and resistance to hop powdery mildew strains found in Washington. The new variety was cultivated as a result of a cross in 2000 at Golden Gate Roza Hop Ranches in Prosser, Wash., United States and has been asexually reproduced in Prosser, Wash., United States.

Abstract: A novel variety of hop, Humulus lupulus L., named “Super Galena” is disclosed. “Super Galena” has relatively high contents of bitter acids, beta-acids, total oil, and humulene, and a moderate, pleasant aroma. “Super Galena” is comparable to Galena in its aroma and bitterness profile but offers a substantially higher yield and complete resistance to hop powdery mildew strains found in Washington, United States. The new variety was discovered among the progeny of a sexual cross made in 1998 in Yakima, Wash., United States and has been asexually reproduced and assessed in field plots in Prosser, Wash., United States.

Abstract: A new and distinct aroma variety of hop plant, Humulus lupulus L., named ‘Delta’ is characterized by its good cone yield, nice aroma (characterized as mild citrus/spice), 1:1 ratio of alpha-acids to beta-acids, low CoH, high Linalool, good storage stability, and resistance to hop powdery mildew. The new variety resulted from cross-pollination performed in 2003 in a field in Prosser, Wash., United States and has been asexually reproduced in a nursery in Prosser, Wash., United States.

Abstract: A new and distinct aroma variety of hop, Humulus lupulus L., named ‘CALYPSO’ is characterized by its large yield, unique aroma and resistance to hop powdery mildew.
