An object of the present invention is to provide a manufacturing method of black vinegar which contains sugar derived from rice and barley abundantly, and is free from precipitation, and black vinegar manufactured by the method.The present invention provide a manufacturing method of black vinegar having the sugar content of 8-50 weight/volume % derived from rice and/or barley, wherein acetic acid fermentation is performed by mixing a saccharified solution and an alcoholic fermented broth of rice and/or barley, and the final concentration of oxalic acid in black vinegar is 36 ppm or less, and preferably 30 ppm or less.In addition, as a decreasing method of oxalic acid in black vinegar, storing with stirring a saccharified solution of rice and/or barley or a fermented broth after completion of acetic acid fermentation is effective. And the present invention provides black vinegar manufactured by these methods in which oxalate precipitation is hardly to occur, and which is suitable for drinking.

A method of controlling the odor of liquid condiments such as soy sauce, vinegar, mayonnaise sauce, Worcestershire sauce and catsup. By using a highly osmotic substance, the odor of liquid condiments is controlled with ease and efficiency while leaving their natural properties unspoiled, without causing such degeneration as might result when additive is employed. A dehydrating sheet comprising semi-permeable external membranes and a highly osmotic substance sealed therebetween is immersed in such liquid condiments for absorbing and removing the unwanted odor-emitting substances contained in them.

A CONTINUOUS PROCESS FOR THE PRODUCTION OF VINEGAR MAY BE CARRIED OUT IN A SINGLE FERMENTATION VESSEL OR A PLURALITY OF FERMENTATION VESSELS INTERCOMMUNICATED IN SERIES. IN EITHER CASES, THE VESSEL OR VESSELS ARE FURNISHED WITH A PLURALITY OF FLOW REGULATING MEANS THEREBY TO ENSURE THE RAPID AND UNIFORM PROCEEDING OF THE OXIDATIVE FERMENTATION REACTION IN ALL PARTS OF THE VESSEL OR VESSELS. ETHYL ALCOHOL-CONTAINING LIQUID IS FIRSTLY INTRODUCED INTO THE ABOVE VESSEL OR VESSELS AND IS INOCULATED WITH AN OVERLAYED LAYER OF ACETIC ACID BACTERIALWHICH HAVE BEEN CULTURED IN A SUTIBALY PREPARED NUTRIENT MEDIUM AND ADAPTED TO ACIDIC BROTH. SUCCEEDINGGLY, FRESH ETHYL ALCOHOL-CONTAINING LIQUUID IS CONTINUOUSLY INTRODUCED INTO THE SINGLE VESSEL OR THE FIRST OF THE SERIES-INTERCOMMUNICATED VESSEL OR THE FIRST OF THE SERIES-INTERCOMMUNICATED VESSELS, AND THE SUBSTANTIALLY FULLY FERMENTED LIQUID IS CONTINUOUSLY WITHDRAWN FROM THE VESSEL OR THE LAST OF THE VESSELS AT AN EQUAL RATE TO THE RATE OF THE INTRODUCTION OF THE FRESH ETHYL ALCOHOL-CONTAINING LIQUID.
摘要:
The present invention discloses a strain S. cerevisiae M 2016785 producing high concentration of β-phenylethanol and application thereof, and belongs to the technical field of industrial microorganisms. The strain S. cerevisiae M 2016785 producing high concentration of β-phenylethanol according to the present invention was deposited in China Center for Type Culture Collection (CCTCC) on Dec. 26, 2016 with the accession number OF CCTCC NO: M 2016785. The strain of the present invention has the high β-phenylethanol production capacity, and is applied in the fermentation of Huangjiu, the fermentation of cooking wine, the brewing of vinegar, the fermentation of soybean sauce and the fermentation of Baijiu, in which the content of β-phenylethanol can reach 410 mg/L, 450 mg/L, 300 mg/L, 200 mg/L, 110 mg/L and 370 mg/L respectively, and effectively increases the concentration of the flavor substance such as 2-phenylethyl acetate. The yeast strain of the present invention has good fermentation performance, obviously improves the β-phenylethanol content in the fermented product, and improves the quality of the fermented product, and thus has broad application prospects.
摘要:
Disclosed herein is a process for producing vinegar of favorable flavor exhibiting inherent flavor, taste and color derived from starting material, comprising the steps of bringing vinegar derived from fruits, etc. into contact with a non-ionic porous synthetic adsorbent, selectively adsorbing to remove iso-valeric acid contained in vinegar and reducing the concentration of iso-valeric acid to below 10 ppm, thereby effectively removing uncomfortable smelly ingredient, while leaving soluble nitrogen ingredient as the tasting or ingredient, organic acids providing mild sourness and color ingredients.
摘要:
A control arrangement for a two-stage submerged vinegar fermentation process for producing vinegar with a high acetic acid concentration of more than 15% is disclosed. The fermentation system includes a main fermentation tank and a secondary fermentation tank, a connecting line with a shut-off valve and a feed pump incorporated therein extending between the two tanks, separate mash and alcohol feed lines with incorporated feed pumps connected to the main fermentation tank, and a vinegar discharge feed line with an incorporated feed pump connected to the secondary fermentation tank. The control arrangement includes an alcohol analyzer and a liquid level sensing device on each of the tanks, a volume flowmeter incorporated in the alcohol feed line, and a controller for each of the tanks. The control connections are such that alcohol is charged into the main fermentation tank in dependence on the alcohol concentration therein, substrate is discharged into the secondary fermentation tank from the main fermentation tank in dependence on the quantity of alcohol charged into the latter, with the transfer being terminated when the liquid in the main fermentation tank reaches a preset lower level, and vinegar is discharged from the secondary fermentation tank in dependence on the alcohol concentration therein having decreased to a predetermined minimum, with the connecting line between the tanks being blocked until the liquid in the secondary fermentation tank has fallen to a preset lowest level.
摘要:
A novel species of acetic acid bacteria belonging to the genus of Acetobacter, to which a scientific name of Acetobacter altoacetigenes MH-24 (FERM BP-491) is given. The bacteria can grow in a culture medium containing at least 4 w/v % of acetic acid with a pH of 3.5 at the highest. Pure samples of species have been isolated and used for the fermentation production of vinegar without undertaking the conventional inoculation process using the prior art seed vinegar to provide a high-quality vinegar of high acetic acid concentration such as white vinegar, with high production efficiency.
