Abstract
Detoxification from seed cotyledons of (Prunus armeniaca) was carried out by
soaking of seed cotyledons in water before and after extraction of oil, and the results
showed that seed represent (15) % of fruit weight, where hull and cotyledons weight
percentages were (62.19) % and (37.81) % of the mature seed respectively. The seed
cotyledons contained high level of crude oil (50.93) % and medium level of protein
(30.03) % and low level of carbohydrate (12.70) % also very low percentage of the ash
and fibers. On the other hand, the seed cotyledons contained high level of hydrocyanic
acid (0.27) %. The percentages of free fatty acids in the extractable crude oils before
and after removing of the toxicity were (0.81) % and (1.69) %, respectively. The
predominant fatty acids found in the crude oil were oleic, linoleic and palmatic acids
and the percentage of unsaturated fatty acids reached (94) % from total fatty acids. The
oil separated into eight components using thin layer chromatography, in which the triethyl
glycerol was the main component. The crude protein and ash content of powder
was reduced after removal of the toxicity by soaking in water. The percentages of
hydrocyanic acid before and after extracting oil between (2.30-3.37) % of the total
hydrocyanic acid in the powder. The effect of removing of the toxicity on mineral and
amino acid content of powder was relatively low especially after toxicity removing
before oil extract. However, the powder was found to have most of the essential amino
acids.
