TAILIEUCHUNG - THE PRODUCTION OF Vinegar from Honey

INEGAR, or dilute acetic acid, is produced by a process of fermentation from certain vegetable substances. After alcoholic fermentation has taken place there follows, under suitable conditions, a further decomposition, by means of which the alcohol is converted into a more highly oxidized body, acetic acid, with water as a byproduct.[1] [Pg 4] These conditions require that the liquid shall contain alcohol, nitrogenous matter, and alkaline salts in certain proportions, and that it shall be in contact with the air, at a suitable temperature, for a sufficient length of time. . | THE PRODUCTION OF Vinegar from Honey.

INEGAR or dilute acetic acid is produced by a process of fermentation from certain vegetable substances. After alcoholic fermentation has taken place there follows under suitable conditions a further decomposition by means of which the alcohol is converted into a more highly oxidized body acetic acid with water as a by-product. 1 Pg 4 These conditions require that the liquid shall contain alcohol nitrogenous matter and alkaline salts in certain proportions and that it shall be in contact with the air at a suitable temperature for a sufficient length of time. The researches of Pasteur showed the process of oxidation to be due to a microscopical fungus mycoderma aceti possessing the power of condensing oxygen and conveying it to the fermentable substance. This organism which is a true bacterium as the fermentation proceeds forms a leathery membrane slightly differing according to the substance fermenting on the surface of the liquor which constitutes the so-called mother of vinegar or vinegar plant. The oxidation of alcohol into acetic acid can also be performed independently of the organic agent. Finely divided platinum for instance is capable of effecting disintegration of the alcohol and of placing it in immediate contact with the oxygen of the atmosphere thus accomplishing the acetification. Pg 5 Vinegar on the continent is prepared from weak or sour wine hence its name vin aigre. In this country it is to a large extent produced from an infusion of malt but considerable quantities of inferior quality are made from sour beer etc. The vinegars thus produced if properly purified and providing no injurious adulterants are resorted to are for many purposes almost all that can be desired but for table use for sauces and salads where .
