REPORT OF THE KING INSTiTUTE, GUINDY
DRAFT STANDARDS AND REGULATIONS UNDER SUB-PARAGRAPH (e) OF SEC-
TION (20) OF THE MADRAS PREVENTION OF ADULTERATION ACT, 1918.
Cow's milk.
(1) Where a sample of cow's milk (not being sold as skimmed or separated milk)
contains less than 3 per cent of milk-fat, it shall be presumed for the purposes of the Madras
Prevention of Adulteration Act, 1918, until the contrary be proved, that the milk is not
genuine, by reason of the abstraction therefrom of milk-fat, for the addition thereto of
water.
(2) Where a sample of cow's milk whether sold as cow's milk or as skimmed or separated
cow's milk, contains less than 8.5 per cent of milk-solids other than milk-fat, it shall be pre
-sumed, for the purposes of the Madras Prevention of Adulteration Act, 1918, until the
contrary be proved, that the milk is not genuine by reason of the addition thereto of water.
(3) Where a sample of cow's milk whether sold as cow's milk or as skimmed or separated
cow's milk, contains less than 0.5 per cent of nitrogen, it shall be presumed, for the purposes
of the Madras Prevention of Adulteration Act, 1918, until the contrary be proved, that the
milk is not genuine by reason of the addition thereto of water.
Buffalo milk.
(4) Where a sample of buffalo milk (not being sold as skimmed or separated milk)
contains less than 4.5 per cent of milk-fat, it shall be presumed for the purposes of the
Madras Prevention of Adulteration Act, 1918, until the contrary be proved, that the milk is
not genuine by reason of the abstraction therefrom of milk-fat or the addition thereto of
water.
(5) Where a sample of buffalo milk whether sold as buffalo milk, or as skimmed or sepa
-rated buffalo milk, contains less than 9 per cent of milk-solids other than milk-fat, it shall
be presumed for the purposes of the Madras Prevention of Adulteration Act, 1918, until
the contrary be proved, that the sample is not genuine by reason of the addition thereto of
water.
(6) Where a sample of buffalo milk whether sold as buffalo milk or as skimmed or
separated buffalo milk contains less than 0.53 per cent of nitrogen, it shall be presumed for
the purposes of the Madras Prevention of Adulteration Act, 1918, until the contrary be proved,
that the sample is not genuine by reason of the addition thereto of water.
N.B.—The minimum limits for nitrogen in sections (3) and (6) are intended to be
used in those cases in which a sample of milk when it is analysed, is so far decomposed that
an estimation of the proportion of milk-solids other than milk-fat in the sample before
decomposition might be unreliable, the proportion of nitrogen not being appreciably affected
by decomposition.
Milk.
(7) Where a sample of milk, separated milk or skimmed milk is sold or exposed for sale
without any indication as to whether it is derived from the cow or the buffalo and by a com--
parison with the minimum limits given for cow's milk in sections (1), (2) and (3) it appears to
be adulterated, it shall be presumed for the purposes of the Madras Prevention of Adulteration
Act, 1918, until the contrary is proved, that the sample is not genuine for the reason given
in the section or sections which are applicable.
Maximum limit for dirt in milk.
(8) Where a sample of milk, separated or skimmed milk, deposits, on standing for a
period of 24 hours or less, an amount of visible sediment exceeding 5 parts per 100,000 (both
milk and sediment being measured by volume), it shall be presumed for the purposes of
the Madras Prevention of Adulteration Act, 1918, until the contrary be proved, that the
sample is not genuine by reason of its containing an excessive amount of dirt.
Butter.
Where the proportion of water in a sample of butter exceeds 20 per cent, it shall be
presumed for the purposes of the Madras Prevention of Adulteration Act, 1918, until the
contrary is proved, that the butter is not genuine by reason of the excessive amount of water
therein.
