摘要:
An analysis method for hop bittering components which comprises a step of separating and analysing hop bittering components by liquid chromatography, characterized by trapping hop bittering components contained in a sample to be measured in a precolumn consisting of an ester type stationary phase for reversed phase chromatography by passing the sample through the precolumn by means of an acidic aqueous solution containing a polar organic solvent, introducing an eluent for reversed phase chromatography capable of eluting the bittering components into the precolumn, and subjecting the eluate to reversed phase liquid chromatography; and an analysis equipment which is suitable for conducting the above method.
摘要:
There are provided a method of extracting essential oil-rich hop extract from hop, using supercritical or subcritical carbon dioxide as the solvent, the above mentioned essential oil-rich hop extract, and a product comprising a mixture of the hop extract and a hop extract residue. There is also provided a method of applying the product to the production of wort or beer. The extraction is carried out either in one stage controlling the pressure of the carbon dioxide in the extraction tank at 80 - 100 kg/cm2, or performing the extraction at a pressure of over 100 kg/cm2 and conducting the separation in two stages. It is possible to produce beer having a pleasant, flowery hop fragrance and a refreshing, deep-bodied hop flavor.

摘要:
Quantitative determination and evaluation of the flavor stability of fermented alcoholic beverages are performed by measuring the changes of the amount of spin adduct from the formation behavior of active oxygen with passage of time using an ESR apparatus and either determining the value on the time axis of the inflection point of changes of the amounts of spin adduct (defined as the active oxygen formation lag time) or determining the amount of spin adduct after a predetermined time has elapsed after the start of measurement (defined as the active oxygen formation activity). The longer the active oxygen formation lag time or the lower the active oxygen formation activity, the greater the oxygen resistance of the fermented alcoholic beverage, thus making it possible to evaluate that fermented alcoholic beverage as having good flavor stability. In addition, if the formation behavior of active oxygen of semi-finished products in the production process is measured in the same manner, the quality of flavor stability when that semi-finished product has become a finished product can be predicted and evaluated.
摘要:
The present invention is directed to a malt for brewing beer prepared by removing lipids by using subcritical or supercritical carbon dioxide, a beer using the said malt, and a method of preparing the said beer. In the beer obtained by using the malt prepared by the method of the present invention, wort clarity is good, filtration becomes rapid, and filtration efficiency is improved. Also, the obtained beer has good foam head retention, good foam lacing, a refreshingly clean taste and good flavor stability.
摘要:
The present invention is directed to a method for producing hop extracts containing small amounts of resin deterioration products, comprising extracting the hop extracts from dry hops using recycled carbon dioxide wherein said carbon dioxide is in a dry subcritical or supercritical condition, and to hop extracts obtained thereby. The hop extracts thus obtained are very useful in the production of high quality beer having a sharp and refreshing taste.
