Vinegar
has been known for centuries. It is simply a dilute
solution of water and acetic acid that contains coloring and flavoring
agents
in very small quantities from source of raw material. A typical
distilled vinegar contains 95% of water and rest is acetic acid , minor
constituents.
It
is made by two successive microbial processes,
- first
being an alcoholic
fermentation effected by yeasts
and the
- second
an oxidation of alcohol by Acetobacter, a genus of aerobic bacteria.
U.S. Food and Drug Administration
regulation states
that the unmodified name vinegar apply only to the product derived from
apples
and that this product contain not less than 4 g of acetic acid in 100
ml of vinegar.
Vinegar also
contains small quantities of ash, sugars,
phosphoric
acid, alcohol, and glycerol.
Vinegar
is made by two process;
- The
packed generator; and
- Submerged
fermentation system.
Air is used in both process.
The
fermentation of sugar into alcohol (ethanol) and which
comprises the first step in manufacturing of vinegar using the yeast
Saccharomyces sp, which proceeds as follow:
C6H12O6
-------> 2C2H5OH + 2CO2 (sugar source) (Ethyl Alcohol) (Carbon
Dioxide)
The
second
fermentation step requires the microorganism acetobacter (Bacterium
aceti) and
oxygen as indicated below:
2C2H5OH
+ 2O2
---------> 2CH3COOH + 2H2O (Ethyl Alcohol) (Oxygen) (Acetic
Acid) (Water)
FYI
Malt vinegar is used extensively in Britain,
and wine vinegar in continental Europe.
Distilled white vinegar and cider vinegar is preferred in USA and Canada.
