Question

Vinegar is prepared from fermented sugar solution by the activities of
A. Acetobacter aceti
B. Bacillus aceti
C. B. subtilis
D. Diplococcus

Answer 1

Hint: Food preservation is the mechanism by which the addition of such agents avoids food spoilage. Vinegar is an aqueous acetic acid solution and trace chemicals that can include flavourings. Fermentation is a metabolic method that via the action of enzymes, generates chemical changes in organic substrates.

Complete answer:
Vinegar is a condiment prepared by alcoholic and subsequent acetic formation from distinct sugar and starchy materials. This can be used as a flavouring agent, food preservation, medication, herbicide, and cleaning agent. The processing of fermented sap vinegar is referred to as a toddy, which contains 4-6% alcohol. Processes are used to manufacture acetic acids, such as orlean, generator, and submerged fermentation.

On the 6th day of fermentation, the orleans process is carried out with maize cob, which produces 3.27 percent acetic acid. Vinegar is the substance produced by a genus of Acetobacter bacteria from the conversion of ethyl alcohol to acetic acid. To improve the industrial production of vinegar, several technological devices have been produced. Generally, the speed of transformation of ethanol into acetic acid in the presence of acetic acid bacteria is included in these changes. The apple is cooked with vinegar. It's a type of acetic acid. Sugar is first fermented into alcohol during the processing of vinegar and the alcohol is then fermented further into acetic acid. For the preparation of vinegar from fermented sugar solution, Acetobacter aceti is used.

Thus, A-'Acetobacter aceti' is the right answer.

Note: Food preservation should be carried out with the utmost care, taking into account the types of agents used. It is necessary to prevent chemicals that can be toxic when consumed. Other factors to be taken into account are that the nutritional value, colour, or texture of food should not be altered by agents.
