摘要:
An apparatus for detecting the absence of a metal vent tube (28) from a bottle filling machine (10) comprises a nozzle (52) that produces a stream (56) of electrically conductive liquid which strikes the vent tube. A solenoid valve (62) controls the flow of liquid to the nozzle and is activated by a control signal from the controller of the bottle filling machine. The apparatus also includes a generator (66) which produces a signatured signal that is applied to the nozzle. A detector circuit has an input coupled to the frame of the bottle filling machine for detecting whether the signatured signal is present in the frame due to conduction from the vent tube. The detector responds to a failure to detect the signatured signal at the input by producing an output signal which indicates the absence of the vent tube. The controller responds to the detector output signal by shutting down the bottle filling machine until corrective action is taken.
摘要:
The isolation and characterization of a group of odorless and non-volatile glycosides from extracted hops (hop solids which have been previously extracted with non-polar solvents) is disclosed. These glycosides are water soluble and consist of a group of aromatic compounds conjugated to mono-, di-, and trisaccharides. These glycosides are responsible for the formation of kettle hop flavor and taste through both chemical and biological transformations. When these glycosides are transformed, they yield an essence and flavorant which imparts a kettle hop flavor and taste when the essence and flavorant is added to an unhopped beer. These kettle hop flavor essences and flavorants provide economy, consistency, flexibility, quality, and convenience to the brewing process because only one unhopped wort is required to brew a stock of unhopped beer. The unhopped beer can then be dosed with the desired amount of kettle hop flavor essence and flavorant.

摘要:
A method is disclosed of preparing a colorless, clear beer by a method including ultrafiltration and the addition of dextrins, bittering agents and a foam enhancer. Methods of preparing improved nonalcoholic malt beverages and making natural beer foaming components also are disclosed.
摘要:
A method of making a fully hop flavored beverage employs a hop flavoring agent comprising an extract of hop solids, the hop solids being the residue of a first extraction of hops to remove the alpha acids. Preferably, liquid carbon dioxide is used for the first extraction of the hops and a polar solvent, such as ethanol or water, is used to extract the hop solids. Beverages made by the method and novel compositions for use in the method are also disclosed.
摘要:
Malt beverages having less than 0.5% v/v alcohol content are made by combining wort with a thick yeast slurry and fermenting sugars in the wort at about 3°C to 7.5°C for 0.5 to 10 hours. The wort has a high extract content, at least 14% by weight. The yeast slurry is obtained from a prior beer fermentation and includes at least 10% by weight of yeast and the balance beer. The wort is combined with at least 10% to 20% v/v of the yeast slurry in the fermentation step.
摘要:
A method of preparing an alcoholic base for the preparation of stable flavored alcoholic beverages which do not form off aromas on storage comprises treating a feed which contains labile components which can in the presence of flavoring agents cause off aromas upon storage by reverse osmosis employing a membrane which does not permit said labile components to pass therethrough, collecting the permeate which passes through said membrane to obtain an improved alcoholic base, and after the labile components which cause off aromas have been removed adding flavoring agents to the alcoholic base to obtain a stable flavored alcoholic beverage.
