BUTTER.
10. The samples submitted were found to have the normal composition
of unadulterated Butters, or of Butter which must at present be regarded
as unadulterated, and they were therefore certified to be genuine.
Boric Acid was not present in any case.
The use of Boric Acid in Butter is forbidden by the Preservatives
Regulations.
MARGARINE.
11. All the samples of Margarine were reported as genuine, and Boric
Acid was not detected in them. In no case did the amount of Butter
Fat in these samples exceed 10 per cent. (Section 8 of the Sale of Food
and Drugs Act, 1899).
CUSTARD POWDER.
12. Under existing circumstances adulteration could not be certified
with respect to the samples of "Custard Powder."
They consisted of starch containing a slight amount of colouring
matter, and were practically devoid of egg or other proteid material.
At present there is no official or generally recognised definition respecting
the composition of articles sold as "Custard Powder."
COFFEE AND CHICORY MIXTURE.
13. The six samples submitted were all certified to be genuine.
They contained the following percentages of Chicory respectively:-
40, 37, 35 (three samples), and 34; the descriptions applied to the
articles were therefore justified.
SAUSAGES.
14. Three of the samples of Sausages were found to contain very
slight traces of sulphur di-oxide. The, amounts present in each case
being well below the limit of the Regulations.
DRIED GREEN PEAS.
15. These samples consisted of green peas dried, and they retained,
to some extent the natural colour of the fresh peas; they were free from
addition of copper salts.
LEMONADE POWDER.
16. The sample was found to consist chiefly of sugar, acidified with
citric acid, and flavoured with lemon, the mixture being coloured with
an aniline dye.
