Some apple juice contained about 70 per cent of juice and 30 per
cent of water, and should not have been described as apple juice without
the qualification that it contained added water. The manufacturers
insisted that no water was added to this juice and sent samples of
apples and apple juice for examination by your analyst but these
confirmed that added water was present either intentionally or simply as
a by-product of careless washing.
A blackcurrant juice contained not more than 43 per cent of juice
and 9.6 per cent of sugar, and should have been labelled "Blackcurrant
drink" and not "Blackcurrant Juice"; and a product, described as
"Guava Juice", contained not more than 30 per cent of juice so that it
should have been described as "Guava Juice Drink" or "Guava Drink".
A can of grapefruit submitted as a complaint contained 280 parts
per million of tin, The maximum quantity of tin recommended by the
Ministry of Agriculture, Fisheries & Food is 250 parts per million, but
the flavour of food is always affected with smaller quantities of tin.
A pinhole had developed in a can of plums as the result of corrosion,
and mould had entered and developed inside the can. Two cans of grapefruit
segments showed definite corrosion and the tin contents were 154
and 210 parts per million respectively. The interior of a can of
rhubarb was corroded resulting in a tin content of 120 parts per million
in the rhubarb and seven further cans were, therefore, submitted, all
of which showed signs of the lacquer coming away from the sides of the
cans, but none of them were as bad as the original. In no case was the
tin found to be less than 50 parts per million compared with the maximum
of 250 parts per million permitted by the Ministry of Agriculture,
Fisheries and Food.
The mould growth found inside a can of carrots was probably due to
a perforation in the lid caused by a stapling instrument or by a case
opener.
A packet of opened deep frozen peas possessed an acialthough the bacterial count was 300,000 per gramme one would have
expected it to be higher to cause the acid odour. It was thought the
peas must have been defrosted and then refrozen.
Two peanut butters were found to be low in carbohydrate content,
and in one case the manufacturers submitted samples of raw and cooked
peanuts for further investigation, but these supplied no clue to the
loss of carbohydrate found originally.
Some beetroot labelled incorrectly as "Baby Beetroot" was pickled
and should have been described as "Pickled Baby Beetroot".
A sample of honey gave a positive Fiehe's test for the addition
of invert sugar; very few pollen grains were present, and the diastatic
activity was weak. As it possessed the flavour and odour of genuine
honey it was possible that it was genuine honey, which had been overheated
and filtered, but it should have been described as "Refined honey".
The proof spirit of some whisky was 59.5 per cent, indicating that
it contained 8 per cent of excess water.
A lemon drink powder was labelled on the front "Instant hot lemon
drink" and on the back "Keep all medicines out of the reach of children".
The label was considered incorrect since the product contained drugs
and was not a powder for the preparation of an ordinary hot lemon drink.
