It was stated that the sample was a proprietary brand whisky which was
always sent out at a higher strength than the Government limit so that more
water than that shown above had actually been added.
11 samples were analysed and 2 of these were adulterated. All the
samples were bought as vinegar; 9 consisted of artificial vinegar, that is,
dilute acetic acid coloured with caramel and 2 consisted of fermented vinegar.
The 2 fermented vinegars contained 45 parts and 30 parts sulphur dioxide
per million respectively. Although vinegar is not included in the list of foods
in which stated amounts of sulphur dioxide are permitted, the Regulations
state that a food may contain any preservative necessarily introduced by the
use of any of these foods, with a reservation as to the amount allowed in the
final product. Malt, glucose, starch, finings, etc., may be used in the manufacture
of vinegar, and some of these are included in the list of foods containing
a permitted amount of preservative.
D 92 (Informal). 7 per cent.deficient in acetic acid.
D 7 (Same vendor as D 92). 7 per cent. deficient in acetic acid.
Vendor cautioned.
There is no legal standard for vinegar. The Local Government Board
in 1911 suggested definitions for vinegar, malt vinegar and artificial vinegar
and convictions have been obtained in cases where samples did not comply
with these definitions. Recently the Society of Public Analysts and the Malt
Vinegar Brewers' Federation have agreed on standards on similar lines to those
suggested by the Local Government Board. In addition, the agreement
stipulates that artificial or imitation vinegar shall be labelled as such, and that
when a purchaser demands vinegar he shall be supplied with malt vinegar
unless notified otherwise.
