The objective of this research to study the chemical composition and microbial load
for some types of pies by performing various chemical and microbial analysis of samples
collected, from different parts of the Syrian coast which are famous for its
production.
This study showed a large variation in the chemical composition of samples by type
of the pastry and place brought from, for example, the proportion of dry matter for peppers
and chard pies collected from Banias was, 75.71% and 44.90%, respectively, and the
percentage of dry matter was 73.88% and 76.18% and the proportion of protein was,
17.76% and 24 .88% for cheese pies collected from Tartous and Latakia 1, respectively.
This study indicated that all the pies contain a high percentage of fat [the lowest in chard
pies (17.64%) and the highest in cheese pies (38.12%)]. Furthermore a high percentage of
sodium was found (the highest in cheese pies 15.31 mg / 100 g and lowest in pepper pies
7.82 mg / 100 g).
The study also showed that these meals meet international standards in terms of
content of lead, cadmium, Nevertheless they are poor in fiber content except for chard pies
which were the most balanced in terms of components, making it the best type of pies in
nutritional aspect.
Finally, the results showed that the microbial load was too high, as the total census of
bacteria was higher than 105 and the total census of yeasts and fungi was higher than 102.
In addition, all pies are not conformed to the Syrian legislation. The study also showed
absence of E.coli and St. aureus of all samples.
Cornstarch has been added, with percentages of ( 5%, 10%, 15%,20% and 25%), to
flour beans both types paste (peeled and non-peeled) prepared for the manufacture of a
quick vermicelli preparation (noodles), in order to study the effect of the additi
on of some
chemical and organoleptic characteristics of this product and to determine the ideal
proportion of corn starch added.
The study has shown that there is an inverse relationship between the reduction of
protein content and the increase of the fat percentage and the increase of starch proportion
up to (25%) in both kinds of bean noodles: peeled and unpeeled.
Increasing the ratio of starch above 15% has affected negatively the resulted noodles
colour and some organoleptic characteristics such as taste and smell with the emergence of
a gradual improvement of the appearance of noodles that resulted from flour peeled beans.
Finally , it was found that the best ratio of added starch is 15%.
A salt stress was applied from 3rd leaf stage until the maturation on three tomato
cultivars (Marmara, Levovil and Picolino). The salt stress was achieved by increasing the
solution EC from 3 (control) to 6.7 dS/m for, Na and Na+Ca treatments, resp
ectively. The
stress induced a significant increase in vitamin C of Marmara and Levovil fruit content
(20.94 and 23.03 mg/100g) as compared to the control (16.62 and 19.43 mg/100g,
respectively). The titratable acidity was increased significantly (17%) only in Marmara and
Picolino. The fruit content of fructose was increased in Levovil and Picolino by 1.4 and 1.7
folds, respectively, as compared to control (11.13 and 18.8g/kg, respectively). While the
content of N in Levovil and Picolino was decreased, under stress, by 33 and 58% as
compared to the control (0.12 and 0.19%), respectively, the P content was increased. The
salt stress decreased the K content in Levovil and Picolino to reach to 0.22 and 0.26% as
compared to control (0.27 and 0.29%), respectively. The calcium addition modified the
stress impact. A significant increase, was registered in Ca content under stress in Marmara
andPicolino as compared to control, while the calcium addition did have any effect on.
This work was designed to investigate the effect of temperature of frozen storage and
its duration on some chemical properties (Protein, Ash, Moisture,Lipid) of fishes Rabbit
fish (Siganus rivulatus). The fishes were subjected (from one weak to 150 day) of frozen
storage at two different degrees of low temperatures (-18 C,-24 C).
The aim of this research is to study the effect of sex, age and anatomical location on
the chemical composition and amino acids of Syrian fattened camel meat.
Samples from dorsal rectangular muscle (Longissimus dorsi), and Semimembranous
muscle in
three age groups (1.5 - 2 years, 3 - 4 years and 5 - 6 years) were analyzed
in triplicates from every age group and from each sex.
Percentage of moisture and protein in the flesh of males was higher than the flesh of
females. Moisture and protein decreased, while fat and ash increased according of animal's
age. Moisture, protein and ash were higher in Semimembranous muscle, while fat was low.
The amounts of amino acids were higher in the flesh of males than the flesh of
females, but the amount of methionine was opposite. The amounts of valine, iso-leucine,
methionine, alanine, glutamine, and tyrosine decreased, while The amount of leucine,
threonine, tryptophan, phenylalanine and aspartic increased by animal age. The amounts of
valine, leucine, methionine, alanine, arginine, histidine, glutamine and proline increased
while the quantities of iso-leucine, threonine, tryptophan, phenyl-alanine, aspartic, tyrosine
and glutamine decreased in semimembranous muscle compared with dorsal rectangular
muscle.
Orange is used in the juice industry, yielding important quantities of by products.
Orange peel is analyzed for chemical composition and water holding capacity. Data show
that, it has high amount of crude fiber, phenolic contents and antioxidant ca
pacity, also it
has high level of water holding capacity. Biscuits are prepared from blendes which contain
a different proportion (5, 10, 15, 20 and 25)% of orange peel flour are also evaluate for
physical and sensory characteristics, chemical composition and rheological properties for
this blendes.
The sensory evaluation does not show any significant difference between control and
that adds with 10% of orange peel flour. Physical parameters, namely, diameter, thickness
and spread ratio were tested. The diameter and thickness of orange peel substituted biscuits
were decreased, whereas spread ratio of biscuits increase with increasing levels of it.
The data reveals that incorporation of orange peel powder in biscuits increase crude
fiber, ash, phenolic contents and antioxidant capacity, it decreases the carbohydrate
content. Rheological properties of the blended flour show increase in water absorption and
stability.
Addition of 40ppm xylanase enzyme reduce the hardness value of the sample in
general, it also decrease the spread ratio as compared to control samples with no enzyme
added.
Sensory evaluation results show good overall acceptability scores for the biscuits
contain 10% orange peel with and without xylanase.
Carob pod is the fruit of the carob tree (Ceratonia siliqua L.). The
fruit and its products, sold both in large stores and local markets,
contribute strongly to the diet of people living in the Mediterranean areas
of Europe.
This study reports th
e composition of carob pods sampled in
Homs, Hama and Coast Regions
The chemical content of Cactus grandiflorus L was studied from
amino acids and sugars. The duration of these materials in the
branches and plant flowers was determined and the relative
proportions of these compounds were determined by using the thin
layer chromatography methods(TLC) and the highly efficient liquid
chromatography( HPLC).
