The aim of this investigation was to compare between liver pate mixtures
manufactured from local raw materials and determine the best mixture.
Twelve pate mixtures with three types of livers (sheep, chicken, calf) and
different concentrations of w
ater and fat were prepared and analyzed for
microbial counts (aerobic, anaerobic, yeast, mold, Staphylococcus spp,
Salmonella spp, Listeria, mono- cytogenes, Pseudomonas aeruginosa,
Clostridium spp, E.coli O157:H7 ،Campylobacter spp), emulsion stability and
sensory evaluation to determine the acceptability of the pate mixtures.
Microbiologically, most of raw materials which used to prepare the pate
mixtures were going with Syrians Standard (No. 2179, 2007), The mixtures
were free of the aerobic microbial counts after the completion of the
sterilization process. Sheep fat was better than vegetable oil for processing liver
pate mixtures. According to sensory evaluation and emulsion stability, the
mixture No12 containing 10 % of three types of liver, 30% sheep fat and 20%
water was the best.
The majority of known polymer materials are electrically insulating.
But there are some of polymers are intrinsically conducting in
nature, However, it is lacking in process ability, and the scope for
manipulation of electrical and mechanical prop
erties is limited. The
method which used to solve this problem is an addition of a
conductive metal filament into a polymer filament yarn. Which can
be directly integrated into a textile, or can be knitted. So we made
a device able to produce this kind of conductive yarns which
depends on melt spinning technique but with the elimination of
necessary pressure for extrusion. And we were able to produce
samples of copper filament coated with polymeric material (low
density polyethylene).
The Ultrafiltration (UF) technology was conducted on samples of akawe
cheese whey to obtain the non-protein and fat whey (permeate) that rich in
lactose and was concentrated by evaporation and carefully prepared after
fortification by nutrients,
(0.2) gr/100ml (NH4)2Hpo4 and (0.2) gr/100ml
MgSo4, and (0.3) gr/100ml (NH4)2SO4, and prepared as a fermentation
medium for yeasts capable of metabolizing sugar, and after that (15) samples
were chosen and chemically analyzed along with the whey. Pure isolated
Kluyveromyces lactis (42-K) yeast, recognized by ß- galagtosidase enzyme
and its important application in food, medicine and pharmacy, was
proliferating on the fermentation medium. The optimal conditions were
determined to obtain single cell protein (SCP). The results referred that
typical conditions of yeast growth were (6.5)% lactose concentration, pH
(5), temperature (30°c), Fermentation time (24) hour, and the optimal speed
of incubator shaker (350) rpm and the typical average of aerator (8%).
The optimal values were applied in the bio fermentor (electrolab) to obtain
biomass which was heated at (75-90 c°) for the extraction of the Single Cell
Protein (SCP).
The chemical analysis was conducted on (15) samples of single cell protein
(SCP), and the results were in accordance with all the Syrian special
specification, and (FOA) specification. The microbial estimated results met
(FOA) specification, and the product was free from toxicity elements and
cancered factors, which proved that the product was with high quality of
proteins.
The single cell protein (SCP) was added to Labneh, that manufactured by
direct method, and to the proceed speared cheese between (1-10%),
alternately with dried skimmed milk. The chemical and microbial analysis of
Labneh met all the Syrian special specification and international codex. The
result of sensory evaluation referred that percentage of single cell protein
(SCP) must not exceed (4%) in the Labneh.
The chemical and microbial analysis of proceed speared cheese met all the
Syrian special specification and international codex. The result of sensory
evaluation referred that the percentage of single cell protein (SCP) must not
exceed (3%) in the proceed speared cheese.
The results of a simplified feasibility study on the Labneh supported by
single cell protein (SCP) (4%), and proceed speared cheese supported by
single cell protein (SCP) (3%), referred to good gaining both of the products.

هدف البحث: إن استخدام الرماد في صناعة السيراميك هو عمل بيئي يسهم في الحفاظ على الموارد الطبيعية، و يساعد في التخلص من النفايات، و يعد خطوة اقتصادية هامة لأنه يخفف من تكاليف صناعة السيراميك إذ إنَّه لا يحتاج إلى عمليات تصنيع مثل الطحن أو السحق.
من هن
ا كان هدف البحث دراسة إمكانية استعمال الرماد، الناتج عن مختلف أنواع الصناعات، بوصفه مادةً أوليةً في صناعة السيراميك المستخدم لتغطية الجدران و الأرضيات.
طرائق البحث : اعتمد البحث على الطرائق التجريبية المخبرية لاستخدام الغضار و الرماد (بنسب مدروسة مخبرياً)، كمواد أولية للحصول على الخلطة اللازمة في عملية تصنيع سيراميك الأرضيات و الجدران. و من ثم تم اختبار كل من المقاومة على الكسر و نسبة امتصاص الماء على العينات المشكلة من هذا الخليط و قارنا نتائج هذه الاختبارات بالمتطلبات العالمية لهذه الصناعة.
النتائج : في هذا البحث تم التوصل إلى تحديد النسب الملائمة لمكونات الخلطة اللازمة لصناعة السيراميك مع تحديد المعايير و البيانات التي تساعد في نقل هذه التكنولوجيا إلى الواقع الصناعي التجاري.
