DYES (from E 100 to E 199) are occasionally under accuse: years
ago it was the turn of amaranth E 123, then of red E 127, used for
chewing gums, ice creams, sweeties and drinks. It was withdrawn from the
market in the States, as suspected to provoke (in cases of massive
assumption) thyroid tumours, in rats, and allergies. In Europe it is
saleable, since it is reputed absolutely safe" in normal quantities. It
recently was tartrazine's turn (E 102), a yellow dye used in drinks,
canned fruit, purée, canned soups, sweeties. In Australia it is banned,
because of possible side effects as asthma, nettle-rash, insomnia and
children's irritability.

PRESERVATIVES (from
E 200 to E 299) prolong the preservation period of the product,
preventing the spread of micro-organisms (bacteria, moulds, fungi).
Nitrites (E 249, E 250) and nitrates (E 251, E 252) are used for meat. A
controlled use is suggested: some of the by-products, like nitrosamines,
showed some cancer effects in animals.
Sorbates (E 201, 202, 203) are used for fat food, benzoate (E 211, E
219) for alcohol-free drinks, sulphur dioxide (E 220) and sulphites (from
221 to 228) for wine, dry fruit, marmalades, fruit juice, peeled
potatoes, pickles in general. Sulphur dioxide, in particular, hinders
the vitamin B1 absorption, possibly causing headaches. Asthma can be
worsened by sulphites. Other preservatives are the phenyls (E 230, 231,
232), used to treat citrus fruits and banana peels, suspected to provoke
nausea.

ANTIOXIDANTS (From
E 300 to 350) prevent vegetables and fruit from oxidisation. The
one used most is th ascorbic acid and its salts (E 300, 301, 302), which
can foster kidney calculus after high assumptions. They are used for
drinks, raw pork, dried mushrooms, vegetables to pickle, raw peeled
potatoes. Other antioxidants are citric (from E 330 to 332), lactic (E
325), tartaric (from 334 to 337) acid.

EMULSIFIERS
contribute to bind fats and water in order to confer smoothness and
creaminess to ice creams, mayonnaise, sweeties and cakes in general.
They come from either animal rests or low quality oils (coconut, palm
trees, E 471, 472) or from soya-beans (lecithin, E 322).

THICKENERS AND GEL
SOLUTIONS amalgamate and give substance to ice creams, gummy
sweets, puddings, desserts in general, fresh cheese. The most frequently
used have a natural origin, and never showed any contra-indication: agar
agar (E 406), extracted from seaweed, Arabic gum (E414), carob seeds
flour (E410), pectin (E 440) contained by fruit.

STABILIZERS
keep constant the product matter, holding water while preventing it to
nurture the development of micro-organisms. They are polyphosphates,
phosphates and fusion salts (E 450), used for cooked ham, cheese,
puddings, meat scrambles. Polyphosphates, when consumed irregularly,
increase osteoporosis and kidney calculus.

- SAPIDITY EXTOLLERS increase savoury
taste and fragrance of meat purées, vegetable stocks, sauces, flaked
purées; the better known is monosodium glutamate (E621), typical of
eastern cuisine, which can, in big amounts, unleash the "Chinese
restaurant syndrome": people who are allergic can feel warm sensations
arousing on the face, ticklish shoulders and chest-ache.
