Definitions
- the present invention relates to a method for producing alcoholic beverages, in particular, to facilitate emission of carbon dioxide gas produced during fermentation, and to take up amino acid in raw material by yeast.
- the present invention relates to a method for promoting the production of alcoholic beverages having a stable flavor.
- the carbon and nitrogen sources in the brewing material liquid are generally consumed by the yeast to produce ethyl alcohol.
- yeast can be used at a high concentration.
- the immobilized yeast is filled in a packed-bed reactor to produce alcoholic beverages such as beads, the following problems occur due to carbon dioxide produced during fermentation.
- Dead space is formed by stagnation of carbon dioxide gas, and the solid-liquid contact area decreases.
- the bioreactors used for fermentation can be classified into three types: (1) stirred tank reactor, (2) packed bed reactor, and (3) fluidized bed reactor. Apart from these, each has its own strengths and weaknesses (the rational design and optimal operation of bioreactors, 151 (1986) Technical Information Center). Tar).
- reactors those with a high carbon dioxide emission effect are the stirred tank reactor and the fluidized bed reactor.
- fluidized bed reactors are characterized by easy temperature and ⁇ ⁇ ⁇ control, good mass transfer characteristics, and low pressure loss of immobilized yeast. It has been used to mellow the alcohol.
- An object of the present invention is to solve the above-mentioned problems and to provide efficient production of liquors using immobilized yeast: DISCLOSURE OF THE INVENTION
- an immobilized yeast is filled in a fluidized bed reactor provided with a liquid circulation pipe and a gas exhaust port, and a brewing material liquid is supplied to the reactor.
- Liquor characterized in that a part of the culture solution is drawn out, and the culture solution is returned from the lower part of the reactor to the inside of the reactor, thereby culturing while forming a circulating flow. It is a manufacturing method of.
- the present invention provides, in the course of culturing by the above-described method, a method of supplying a brewing raw material solution to a reactor and extracting a part of the culture solution outside the reactor.
- the present invention relates to a method for continuously producing alcoholic beverages.
- an inert gas is introduced from the lower part of the reactor.
- a method is employed in which the immobilized yeast is caused to flow by circulating the liquid.
- FIG. 1 is an explanatory diagram showing one example of a fluidized bed reactor used in the present invention.
- FIG. 2 is a graph showing the time-dependent change of pseudoex in the continuous fermentation of Example 1.
- (1) is a wort tank
- (2) is a pump
- (3) is a pH sensor
- (4) is a fluidized bed reactor
- (5) is a temperature sensor.
- Sir indicates a gas outlet
- (7) indicates a product tank.
- alcoholic beverages are produced using the fluidized bed reactor shown in FIG.
- the generated carbon dioxide gas is easily discharged by forcibly circulating a part of the fermentation liquor.
- the fermentation liquor in the reactor is withdrawn from the upper part and introduced into the lower part through a pipe, so that the fermentation liquor is fluidized. I am doing it. Therefore, the carbon dioxide gas produced during the fermentation is discharged out of the reactor from the gas exhaust port without being dissolved in the liquid. Therefore, it is possible to avoid the effect of carbon dioxide on the metabolic activity of yeast. I will.
- the brewing material liquid may be any liquid that is suitable for the growth of liquor yeast such as beer yeast, vien yeast, and sake yeast, and any known brewing liquid may be used.
- liquor yeast such as beer yeast, vien yeast, and sake yeast
- malt juice, fruit juice, sugar solution, saccharified cereal solution and the like are used alone or in a suitable mixture.
- appropriate nutrients can be added as needed.
- the brewing material liquid is sterilized by an ordinary method and then supplied to a fluidized bed reactor filled with immobilized yeast, and the supply amount is 0.55 to 0.2 hr. -', Preferably 0.1 to 0. Shr — 1 .
- the space velocity is obtained by multiplying the amount of the brewing material liquid supplied to the fluidized bed reactor per unit time by the amount of the immobilized carrier supporting the enzyme. It is.
- the amount of the immobilized carrier supporting the yeast is suitably 5 to 50 volumes, preferably 10 to 30% by volume, based on the reactor volume.
- the brewing material liquid can be introduced from an appropriate position such as the upper and lower parts of the reactor.
- alcoholic yeast which produces alcohol and carbon dioxide gas by metabolizing the brewing material liquid.
- Alcoholic yeasts such as beer yeast, wine yeast, and sake yeast The mother may select it appropriately according to the purpose of use.
- Saccharomyces selevische 0C — 2 IAM 4175
- Saccharomyces semester Celebiche Kyokai wine yeast No.1, Saccharomyces Selebiche Kyokai wine yeast No.3, Saccharomyces Selebiche Kyokai wine yeast No.4 etc.
- These yeasts are generally well known; the first strain is stored at the Institute of Applied Microbiology at the University of Tokyo, and the other three are stored at the Japan Brewing Association. It is available and can be obtained easily.
- yeasts are generally facultatively anaerobic.
- Various carriers can be used as a carrier for supporting the yeast.
- chitosan beads, alginate beads, and porphyrinase can be used. Beads and the like are preferable, and beads such as ceramics and glass are not suitable as the carrier of the present invention because they are vulnerable to abrasion.
- the immobilization of yeast is known per se (for example, Saburo Fukui, Ichiro Chibatake, Shuichi Suzuki, edited by Enzyme Chemistry (Tokyo Kagaku Dojin), David Williams, Douglas M. unnecke; Biotec. And Bioeng., 23, 1813 (1981)), and the present invention may be carried out by a known method.
- the fermentation temperature is usually 15 ° C or lower, preferably 8 to 10 ° C for beer acid production, for example. In the case of brewing, it is usually around 20 ° C, preferably 15 to 20 ° C.
- the circulation rate of the fermentation broth circulating during the fermentation is, for example, 150 to 400 m1 per minute, preferably 200 to 2 m2 for a 1 liter reactor. 5 O ml is appropriate.
- the fermentation liquor is in a state close to complete mixing, and fermentation can be performed efficiently.
- the fluidized bed reactor used in the present invention has good mass transfer characteristics, and therefore, the amino acid and the like contained in the brewing material liquid are subjected to fermentation during the fermentation process. It is taken up by yeast and assimilated. Therefore, the concentration of amino acids in liquor products is lower than that of the conventional method, and the flavor is good.o
- the method of the present invention can be used not only for producing beer but also for producing other liquors such as wine and sake.
- a carrier chitosan beads
- immobilized beer yeast Sacharomyces cerevisiae IAM4206 (ATCC9080)
- the wort which had been filled with 50 ml and adjusted to the original wort extract 11 ⁇ Plato, was introduced into the reactor at 75 ml, and the circulation rate of the fermented liquor in the reactor was reduced to 25 O ml Z In minutes Bass Sea Piggu Mouth Fumehiri 8
- the concentration of the amino acid in the fermentation broth is lower than that of the comparative example and the control method. Is low.
- a carrier chitosan beads immobilized with Wien yeast (Saccharomyces' Selpicie C-2 (1AM4175)) is flowed at a capacity of 1 liter.
- the bed reactor was filled with 250 ml, and wort adjusted to a sugar content of 22% Plato was introduced into the reactor, and the circulation rate of the fermented liquor in the reactor was increased to 250 ml / min.
- the batch fermentation was carried out at 20 ° C with the temperature set to.
- a fluidized bed reactor filled with immobilized yeast is used, and the fermentation solution in the reactor is circulated.
- the immobilized yeast is fluidized, so that most of the produced carbon dioxide gas can be discharged out of the system without being dissolved in the liquid.
