Qualitative Analysis
The number of milk samples submitted to the public analyst for
chemical analysis was 189 of which 24 were "Channel Island" milks. The
latter are required to have 4% fat as against the legal minimum of 3%
for ordinary milk. All complied with the prescribed standards. The
average fat and non fatty solids content of the 24 "Channel Island" and
"South Devon" milks was 4.4% and 8.91% respectively. That of the
165 ordinary milks 3.57% and 8.66%.
Ice Cream
Ninety-eight samples of ice cream were examined for bacteriological
purity and as in the past three years all were found to be of the highest
grade—grade I.
The following is the analysis of the result of sampling since this system of bacteriological grading was first instituted in 1947:—
