Abstract: A condensed wire composition containing an extract content of no less than 18% (w/v) is obtained by vacuum condensing a wine at a temperature of 5.degree. to 60.degree. C., preferably 20.degree. to 35.degree. C. to a concentration by at least 8 times as high as the original, retaining the resulting condensate at a low temperature, e.g., 0.degree. to 10.degree. C. to crystallize tartar, and removing the tartar. An initial distillate obtained upon the vacuum condensing of the wine and/or brandy may be added to the condensed wine in such an amount that final product has an alcohol content less than 1% (v/v).

Abstract: A draught beer dispensing system according to the present invention comprises a beer receiving receptacle, a beer dispensing valve from which the draught beer is dispensed into the receptacle under the pressure of carbon dioxide gases, a source supplying carbon dioxide gases, and a movable dispensing nozzle connected to the beer dispensing valve through a flexible pipe and operated by an actuating means. When draught beer is dispensed, the tip of the beer dispensing nozzle is positioned within the receptacle first and is moved upwardly to the upper edge of the receptacle upon completion of beer dispensing.

Abstract: A draught beer dispensing system according to the present invention comprises a draught beer receiving receptacle, a beer dispensing valve from which draught beer is dispensed into the receptacle under the pressure of carbon dioxide gases, and a source of supplying the carbon dioxide gases. The beer dispensing valve includes an automatically controlled ball valve. The ball of the ball valve has a through hole. When the ball valve is controlled in a fully open position, draught beer can be dispensed without any foam; while the ball valve is controlled in a partly open position, draught beer can be dispensed with foams whereby to give the almost filled out receptacle some finishing foams.

Abstract: A draught beer dispensing system according to the present invention comprises a pressure regulating valve for regulating pressure of carbon dioxide gases supplied from a source of supplying carbon dioxide gases to a draught beer receiving receptacle, a temperature detector provided adjacent to the receiving receptacle to detect a temperature of draught beer within the receiving receptacle, and an arithmetically control device for controlling the pressure regulating valve on the basis of a detected value of the temperature detector, wherein in dispensing the draught beer from the draught beer receiving receptacle, a temperature of the draught beer within the receiving receptacle is detected by the temperature detector, the detected value is inputted into the arithmetically control device, supplied pressure of carbon dioxide gases supplied into the draught beer receiving receptacle is arithmetically operated on the basis of the relationship between beer temperature and pressure stored in advance in the arithmet

Abstract: A cyclodextrin adsorbing material composed of a water-insoluble resin substrate to which a ligand having such a size as to be included by cyclodextrin is chemically bonded via a spacer radical; a method of separating and purifying cyclodextrin from an aqueous solution containing it, which comprises bringing said aqueous solution into contact with the above adsorbing material to adsorb cyclodextrin on the adsorbing material, and subjecting the adsorbing material to a desorption treatment to recover cyclodextrin; and a method of increasing the amount of cyclodextrin yielded, which comprises carrying out a cyclodextrin-forming reaction by an enzymatic method in the presence of the above adsorbent material.

Abstract: Partially methylated cyclodextrins with enhanced solubility in water have an average degree of methylation of hydroxyl groups at different positions in all the glucose units involved of about 53-64% for the 2-position, about 38-51% for the 3-position and about 70-100% for the 6-position. The partially methylated cyclodextrins are prepared by reacting .beta.-cyclodextrin with more than about 30 equivalent proportions based on the .beta.-cyclodextrin of dimethyl sulfate and more than about 30 equivalent proportions of an alkali metal hydroxide, wherein the concentration of reactants is greater than 10% (wt/wt).

Abstract: A process for producing cyclodextrins which comprises using cultured medium of the strains belonging to genus Micrococcus, filtrate thereof or enzyme preparation obtained therefrom, especially, the process in which the ratio of .alpha.-cyclodextrin to .beta.-cyclodextrin can be desirably varied by regulating the condition of the reaction mixture, is disclosed.
