Abstract

Give inform
about the dangers of aflatoxin and propose a solution toxin development in
grain products.

Empirical
mycotoxins research in grains on a national basis examined, it has been
compiled in this study.

Aflatoxins are
one of the most toxic mycotoxins and they are constitutively carcinogenic
seconder metabolite of A. flavus ve A. parasiticus strains. When the moisture
content of the grain 17-19 % range, A. flavus development starts. The age, sex,
exposure-dose, diet and some health factors affect the degree of toxicity.
Aflatoxins are mutagenic, carcinogenic and a teratogenic effect of acute
toxicity has been observed in animals and in humans. The liver is the most
impressible organ with regard to aflatoxins which toxins affect DNA-RNA
synthesis and some metabolic systems.

Grains are not
contaminated with mold while they are growing but despite the low water content
mature products appear to be contaminated with mold quickly if left on the
ground. Even if contaminated molds generates mycotoxin; product moisture
content, temperature, processing and relative humidity at storage active for
toxin synthesis.

If we consider molds
are mostly found in soil, products not directly storage at soil, grains drift
away from soil and harvest in time are points to take into consideration. it is
recommended that grains in silos storage at under controlled atmospheric
conditions with controlling the amount of oxygen, temperature and moisture.
Becouse this conditions lead to the development of mold and products prevent
from wetting in harvest at rainy regions. Also should be give weight to toxin
analysis (especially aflatoxin analysis) in risky product groups for grains.
