تمت هذه الدراسة على بعض الخضار و الفواكه المحلية قبل و بعد النضج (تفاح, خوخ, دراق, جنرلك, بندورة) و البقوليات الخضراء و المجففة (فول, حمص, عدس, بازلاء, لوبياء) و البذور الزيتية (فول سوداني, سمسم, ذرة) و الحبوب و منتجاتها (قمح, شعير, شوفان, رز مستورد, طحين و خبز بأنواعهما, نخالة, برغل) المستهلكة في مدينة اللاذقية، و تبين بأن أغلب هذه المنتجات تحتوي على مستويات عالية من حمض الفيتيك و لاسيما المنتجات غير الناضجة (0.15-3.57 غ%غ.م.ج) و مشتقاتها (0-1.95 غ%غ.م.ج).
This study is carried out to determine phytic acid in some local vegetables and fruits, before and after ripening (apples, peaches, pean, tomato), green and dried legumes (beans, chickpea, lentil, peas, soybean, maize ….), and oil seeds (peanut, sesami, ……) and cereals and their products (grain, barley, oats, rice, bread kinds, bran, borghol) that are consumed in Latakia city. Most of the products contain high levels of phytic acid, especially in green products and their derivatives; the values range between (0.1-3.57 %) and (0-1.95 %) on dry bases respectively.

The samples of various food products have been collected at several times per season
over two years, in order to determine the content of phytic acid to investigate the influence
of the adopted treatment methods on phytic acid degradation and to mi
nimize their
unhealthy effects.
It's been shown that PA is found at high levels in the mentioned products especially,
in unripe fruits where its levels ranged between (0.15-3.57%g.s.d) while PA levels were
less in the process products and ranged between (0-1.95 %g.s.d).
Technological processes were applied to biodegrade phytic acid of some foods and
the reduction ratio ranged between 20-60% of the whole content of PA.
The incidence of contamination with ochratoxin A (OTA) in baby
food products consumed in Syria was investigated using the
competitive enzyme linked immunosorbent assay (ELISA)
technique.
Soft wheat is a good source of Phytic acid. The objective of this
work was to develop wheat phytic acid extraction and purification
techniques.
This research has included quarterly and periodically physical and chemical analysis
of treatment wastewater in the rural areas of Latakia city during year 2011 by testing
three treatment plants similar in the mechanism of action and distributed in
three villages
(Happit, Al-Harah, Marg Moairban).
This study has included the measurement of temperature T, pH, and determination of
sodium, potassium, calcium concentrations, and sodium adsorbed rate (SAR).
This study was based on the potentiometrictechnic using Ion Selective Electrodes
(ISEs).
SAR measurements have shown that there are clear differences between autumn and
other seasons, and between treatment plants. The highest values was in the Happit
treatment plant in all seasons and the highest value was (88.25 mg/L) in the autumn which
is much larger than the allowable limit.
The highest concentrations of sodium ion were in the autumn in all treatment plants
(1002.67-7130.33) mg/L, which is off limits. As for the potassium ion concentration was
highest (72.46 mg/L) in Happit treatment plant in the autumn. While calcium ion
concentrations in Al-Harah treatment plant was exceeded (670.33-800.00) mg/L the
allowable limit in all seasons except the summer.
The statistical study has demonstrated and showed strongand sometimes weak
correlation coefficient R2 so that gives clear indications about the sources of pollution.
This research has included quarterly and periodically physical and chemical analysis of treatment wastewater in the Latakia countryside during year 2011 by testing three treatment plants similar in the mechanism of action and distributed in three v
illages (Happit, Al-Harah, Marg Moairban).
This study has included the measurement of temperature, pH, dissolved oxygen, turbidity, and determination of nitrate, phosphate, sulfate, and chloride.
In this research, potentiometric using Selective Electrodes ISEs, the Visible Spectrum, and the Turbidimetry methods were used.
The results showed significant differences in concentrations of the studied ions between one station to another. The highest nitrate concentrations (228.33mg/l) were recorded in Happit treatment plant especially in summer, and the highest phosphate concentrations (41.81mg/l) were in Happit treatment plant in summer. Whilst the highest sulfate concentrations which ranged between (508.67– 1157.33)mg/l were in Al-Harah treatment plant at all seasons. The highest chloride concentrations (310.33mg/l) recorded in Happit treatment plant in summer.
The statistical study has demonstrated and showed high and sometimes low correlation coefficient R2 so that gives clear indications about the sources of pollution.
