CREAM BUN.
7. The sample was adulterated and was certified to contain 30.77
per cent. of fat other than milk fat in the "Cream" portion. The fat
of the cream portion should consist entirely of fat derived from Milk,
that is Butter fat.
BUTTER.
8. Two samples of Butter were reported as Inferior; they contained
15.13 per cent. and 14.53 per cent. respectively, of water, and were
both below the limit laid down by the Act of 16 per cent.; in view
however, of the high percentage of water, they were reported as stated.
Properly prepared butter should not contain more than 12 or 13 per cent.
of water.
COFFEE AND CHICORY MIXTURE.
9. These samples were found to contain the following percentages
of Chicory:—
44, 36 (2), 35 (2), 34, 33 (2), and 30,
and therefore the composition of these mixtures had been correctly
described.
RAISINS.
10. The samples of Raisins were found to contain the following percentages
of Sulphur dioxide.
per cent. parts per million.
0.03433 343.3
0.021973 219.73
0.01648 164.8
0.01373 137.3
The limit of the Regulations is 750 parts per million.
MIXED FRUITS.
11. One sample contained 82.4 parts per million of sulphur di-oxide,
an amount well below the limit.
TINNED TOMATOES AND PEARS.
12. Both these samples contained a very slight amount of tin
from the metal containers, but the amounts were too small for
estimation.
BEEF SAUSAGES.
13. The sample was certified to contain 151 parts of sulphur dioxide
per million parts of the sausages, but as the presence of a preservative
was declared at the time of purchase, and as the amount was well under
the limit of 450 parts per million, the sample was reported as genuine.
CREAM.
14. The fat of all the samples was of the composition of fat derived
from milk ; they were free from preservatives, and were otherwise of
genuine composition.
CUSTARD POWDER.
15. All the samples consisted of starchy matter coloured with an
aniline dye, and were practically devoid of Proteid matters, but in the
absence of any official definition of the articles the samples were reported
as genuine.
