نظرا لكون حبوب القمح تحوي على نسبة عالية من حمض الفيتيك استخدمنا في هذه الدراسة حمض الفيتيك المستخلص من حبوب القمح الطري في حفظ لحم العجل المطبوخ و تم دراسة فعله المضاد للأكسدة من خلال منع أو تقليل أكسدة الميبيدات. تم في هذه الدراسة استخلاص حمض الفيتيك من حبوب القمح الطري و تم تبيان تأثير إضافته في حفظ لحم العجل المطبوخ, بالإضافة إلى دراسة خصائص لحم العجل الطازج و المطبوخ المحفوظ بالتبريد و المعالج بحمض الفيتيك كمضاد أكسدة طبيعي.
Soft wheat is a good source of Phytic acid. The objective of this work was to develop wheat phytic acid extraction and purification techniques.

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.
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, sesa
mi, ……) 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 aim of this investigation was to prepare mortadella from Awas meat by
adding different amounts of soya meal (i.e.15%, 20% and 25%), and
comparing it with standard (no soya added) one. Other additives were also
incorporated with fixed amounts f
or all used mixtures.
Chemical analyses (i.e., moisture content, protein, carbohydrates and ash
contents) were determined for each blend. Also a group of microbiological tests
(i.e. Staphylococcus, E. coli, Salmonella and total number of mesophilic
bacteria), test evaluation has been carried out to determine the acceptability of
the blends by the customer and the economic value was also evaluated.
The results revealed that, as the added amount of soya meal increased, the
testing traits, such as, test, flavor, color, and texture were deteriorated, the
total microbial number was also decreased, and the content of water as well as
carbohydrates was also declined.
A landrace (Hourani-٢٧) and two newly introduced cultivars (ACSAD-٦٥
and Amra) were grown at five different locations (JUST, Shajarah, Hawarah,
Kharja and Turrah) with or without NP treatment.
This study included a test of 90 chickens; 90 samples as (a chest) and 90 samples as (a thigh). These samples were divided into four categories: the first one (45 chests) was stored with packages in a tin sheet, the second (45 chests) unpacked, the t
hird (45 thighs) was stored with packages in a tin plate, the fourth (45 thighs) unpacked. The samples of each category were divided into three groups. Each group consists of 15 samples. These groups were stored at (25+°, 4+°, 20-°) .Then, the pH and the total count of bacteria were measured during storage in order to observe the time in which the samples will start to spoil in accordance with the Syrian Standards and Specifications Corporation 2007. We noticed the following physical changes: color, odor, flavor and texture. The results showed that the spoilage of the thigh samples happened before the chest ones and the packaged samples before the unpackaged ones. The samples spoiled after 24h of storage at 25+° and after 7 days of storage at 4+°, whereas, there was no spoilage noticed for the samples at 20-° but the appearance changed after 6 months of storage. Packing had a good effect on preservation. The conclusions and the suggestions were written in order to guide the consumer in the field of poultry meat storage.
