Lemon Juice
This sample of lemon juice was packed in a plastic container
and was found to have fermented and to be in a turbid condition.
It was not considered to be suitable for human consumption and
the shop keeper surrendered the remainder of his stock.
It is understood that some difficulties had been experienced by
the manufacturers in the use of plastic containers for this product
and the marketing of this particular brand of lemon juice is now
being undertaken by a firm well known in the food trade. Subsequent
samples have proved satisfactory.
Milk
A half pint bottle of milk was examined to identify the nature of
some small greenish coloured foreign bodies. These proved to be
fragments of leaf tissue and evidence that the bottle had probably
been previously used as a vase for flowers.
Hot Milk
This sample of hot milk which was obtained in a cafe contained
11 per cent, of added water. The milk was heated by means of a
steam pipe being placed in the glass. Whilst this is an easy method
so far as the shop assistant is concerned it is not satisfactory
that a customer who is asked to pay 7d. for a tumbler of "hot milk"
containing approximately 6 fluid ounces should receive as much as
11 per cent, added water.
Powdered Pectin
A sample of powdered pectin was found to contain 340 parts
per million of sulphur dioxide. On enquiries being made of the
distributors it was found that this particular commodity had been
manufactured during the early part of the war and that none had
been marketed or sold by the firm since 1942.
The multiple firm of grocers selling the product agreed to withdraw
their remaining small stock from sale and no further action
was taken.
Soup—Cream of Mushroom
On analysis a sample of soup sold as "Cream of Mushroom"
was found to contain only 2.5 per cent. of fat. An examination of
the fat showed that it contained no appreciable amount of butter
fat. A warning letter was sent to both the vendor and manufacturers.
Soup Mix—Clear Chicken
The analysis of an attractively packeted Soup Mix proved very
interesting. The labelling obviously led the purchaser to believe
that the soup cubes contained in the packet would, when prepared,
produce a Clear Chicken Soup. Analysis showed that when prepared
according to the instructions the resulting soup contained only
