摘要:
The present invention relates to the use of a proline-specific protease for accelerating the beer brewing process. In particular, it relates to the use of a proline-specific protease for accelerating the beer brewing process by shortening and simplifying the stabilisation phase of beer production. The stabilisation period as such can be omitted from the beer making process hereby saving significant costs and adding to the flexibility of beer producing plants.

A production method of a beer-taste alcoholic beverage with foaming properties which does not use barley wheat and malt, in which a proteolytic enzyme improving generating foam and foam stability is used as a part of a substance of raw materials, and the alcoholic beverage with foaming properties produced by the production method are disclosedThe production method of an alcoholic beverage with foaming properties, in which a pre-fermentation liquid is processed using a syrup containing sources of carbon, sources of nitrogen, hops, coloring matter, an improving substance for generating foam and for foam stability, and water as raw materials without using barley, wheat and malt, and the pre-fermentation liquid is fermented using a brewers' yeast. A proteolytic enzyme which has high enzymatic activity of the end-type protease activity and partially decomposes macro molecular protein is added into a mashing process as one part of a substance of raw materials together with pea protein, and a enzymatic reaction is performed. Thereby the production method of the alcoholic beverage with foaming properties having improved foaming properties and the alcoholic beverage with foaming properties produced by the production method can be provided. Also, the suitable ratio for the using amount of the added proteolytic enzyme having high enzymatic activity of the e protease is preferably 0.5-2% of the enzymatic amount per pea protein as a substrate which is condensed 10 fold, the reaction temperature of the enzyme is preferably 80-85° C., and the reaction time is preferably 30 minutes.

Enzyme degrading rhamnogalacturonane II (RG-II) having an endo-.beta.-L-rhamnopyranosyl-(I.fwdarw.3')-D-apiofuranosyl hydrolase activity and/or an endo-.alpha.-L-fucopyranosyl-(I.fwdarw.4)-L-rhamnopyranosyl hydrolase activity. This enzyme can be produced by a microorganism, especially of the penicillium species, such as the branches 1-1577 and 1-1578 lodged with the CNCM. The RG-II can obtained from plant extracts by means of a method comprising a chromatography stage.
摘要:
A process for expressing extracellular .beta.-glucosidase in a filamentous fungus by expressing a fungal DNA sequence encoding enhanced, deleted or altered .beta.-glucosidase in a recombinant host microorganism is disclosed. Recombinant fungal cellulase compositions containing enhanced, deleted or altered expression of .beta.-glucosidase is also disclosed.
摘要:
The filterability of glucose syrups obtained from impure wheat or other cereal starch is improved by treatment with Disporotrichum. Also the separation of starch from other constituents of impure cereal starch is improved by addition of xylanase before the starch is separated.
摘要:
Ethyl carbamate in an alcoholic liquor is decomposed by contacting the alcoholic liquor with a culture broth or processed matter thereof obtained from a microorganism which belongs to the genus Gluconobacter, Flavobacterium, Arthrobacter, Achromobacter, Alcaligenes, Pseudomonas, Klebsiella, Rhodotorula, Rhodosporidium, Trichosporon or Candida, and is capable of decomposing ethyl carbamate. The alcoholic liquor is improved in quality, and has a low ethyl carbamate content.
摘要:
Preparation of a proteinaceous material suited for use in milk substitutes by treatment of crude vegetable proteins such as soy flour, faba bean flour and the like with an SPS-ase preparation. In addition to conversion of the vegetable protein, the treatment hydrolyzes the soluble polysaccharide content in the crude vegetable protein into predominantly mono- and di-saccharides, including dissolving +hydrolyzing previously insoluble polysaccharides.
摘要:
Hydrolysis of plant kingdom polysaccharides by treatment with SPS-ase preparations.SPS-ase is an enzyme adapted to hydrolyzing the water-soluble protein binding polysaccharide present in soy flour decomposed by use of conventional pectinases, which polysaccharide is believed to be widespread in plant kingdom substances. Treatment with an SPS-ase preparation can clarify juices, wines and beers, hydrolyze process wastes such as sugar beet pulp, pomace, and soy milk remanence, improve the digestability of silage, and reduce the viscosity of wort.
摘要:
This invention relates to a process for the production of a colloidally sle beer. More particularly, the object of the invention is to modify the common method of preparation of beer, in order to improve the colloidal stability of the beer, i.e. in order to reduce the colloidal turbidity in the beer.A sufficient proportion of polyphenoloxidase is added to the brew or to the wort for precipitating the polymers formed by oxidation of the polyphenols by said polyphenoloxidase, jointly with the proteins in presence, the obtained precipitate being separated by filtration after the oxidation of the malt.
摘要:
A novel hydroxy-cinnamic acid ester hydrolase can be obtained by cultivating, in a medium, a mold strain belonging to Genus Aspergillus or Genus Botrytis and having an ability to produce a hydroxy-cinnamic acid ester hydrolase specifically hydrolyzing the ester linkage of hydroxy-cinnamic acid ester substances represented by the following general formula: ##STR1## wherein R is hydrogen atom, hydroxyl group or methoxyl group and X is tartaric acid residue or quinic acid residue, followed by collecting the hydroxy-cinnamic acid ester hydrolase from the cultivated product.
