Orange fruits contain many materials such as oils in seeds which
have biological and nutritional values, due to that, physical and
chemical properties of orange seed oil (OSO) have been
determined, which extracted from two samples collected from two
areas (Al-ssisanyah and Al-jma'ashyah) which are different in
environmental factors.
In order to achieve the safety of the product of orange juice packed
in glass bottles, the physical, chemical and biological hazards that
are likely to be found in all stages of industrialization have been
studied, based on the methodology of inte
rnationally approved
hazard analysis according to the HACCP methodology. This study
identified all the potential risks associated with this industry, which
were three basic stages within the manufacturing line: the
pasteurization, the closing phase and the cleaning phase (CIP).
The study investigated the possibility of removing heavy metal ions (Cd, Pb) from
aqueous solutions using adsorption method on the citrus peel (orange), which is a solid
waste available in abundance especially in the Syrian coast as well as easy to
use at low
cost. The optimal conditions for the simultaneous adsorption of the ions (Cd 2+, Pb 2+) on
the surface of orange peel (dry, soft) were determined.The concetration of ions was
determined using (DPASV) method Which is characterized by Sensitivity and high
accurawcy. The results showed that the optimum adsorption conditions were at pH = 5 ,
equleibrium time = 60 min, and the initial concentration is ( C0 = 50-200) ppm,The
application of the Langmuir and Frienlish models showed that Frienlish model is best fited
for expressing the adsorption of Pb ions on the surface of dry and soft orange peel and for
expressing the adsorption of Cd ions on the surface of soft orange peel , Langmuir model
is best fited for expressing the adsorption of Cd ions on the surface of dry orange peel.
The method applied its selected terms to realistic samples of processed and industrial
waste water, which showed a unique response as a purification method for the water
media.
The research aims to examine the role of sales promotion techniques (free samples, coupons, discounts, competitions) in the purchase decision in Orange Mall in Latakia. Find adopted a descriptive approach, it was developed a questionnaire to gather p
reliminary data for the sample items, of (170) customer, where questionnaires were distributed to them and recovered the researcher (153) to identify and complete response rate (90%). The results showed that sales promotion methods (free samples, coupons, discounts, competitions) have a positive impact on the purchase decision in Orange Mall in the city of Latakia, where explain the combined sales promotion methods accounted for 48.8% of the purchase decision. The results also show that the discounts are the most influential in making a purchase method and explains what rate (62.7%), followed by free samples and interpret (46.6%), followed by contests and explain (35.8%), followed by coupons and explain (30.6%), from ongoing changes in making a purchase decision.
The study was carried out on trifoliate orange rootstock trees (Poncirus trifoliata L.)
at Ciano Research Station where the trees were sprayed with nutrients or gibberelic acid
GA3 or togethers, beside the control (without spraying). Different trea
tments of seed
storage were tested in order to study their effect on seed viability to increase it. The seeds
were stored for three months using four treatments: (a) seed storage in fruits at +4˚C, (b)
Storage in juice at +4˚C, (c) Storage at lab temperature, and (d) seed storage at fridge
temperature +4˚C. The results showed that all spraying treatments were positive at
postharvest, as compared with the control. However, treatment of seed storage inside the
fruit gave the highest significant germination rate for all spraying treatments. Treatments
of spraying with nutrients were the best. The viability of seeds considerably decreased for
all treatments of seed storage at fridge temperature +4˚C, whereas germination was zero for
seed stored in juice and seed stored at lab temperature.
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.
The research was conducted at Faculty of Agriculture, Damascus University/
Syria, with the help of Scientific Agricultural Research Center in Latakia during
2013 and 2014 seasons. Three rootstocks were used i.e. Sour orange, citrumelo
and troyer c
itrange, to study some factors affecting the success of micrografting
technique (concentrations and periods of sterilization, rootstock, shoot tip size, type
of nutritive medium and the grafting method). The nutritive medium was prepared,
and the shoot tips was isolated from Navel orange source, then the micrografting
was done for the three rootstocks.
Fruits' trading is considered one of the most important agricultural trades
in Syria, due to its big incomings and its role in supporting the national
economy. GAFTA members are representing the biggest partner for Syria in
this trade.
The aim of
this research was to assess the impact of GAFA on the exports
and imports of orange and apple which are considered the most important
Syrian fruits, by using dummy variables through the time series of (1994 -
2010). The research showed that GAFTA had no significant impact on any of
the studied commodities through the transitional phase (1998-2004), while it
had a positive significant effect on both of the exports and imports of these
commodities after the full implementation stage (2005-2010). Significant
differences were found between the three stages (before- during- after) GAFTA
implementation. after implementation stage showed significant differences
comparing to the other stages, in which the exports and imports of both orange
and apple had increased in this stage comparing to the previous ones by
quantity and value.
Orange fruits are characterized at harvesting with physical and sensory
properties determine consumer acceptance and in order to identify these
characteristics and vulnerability storage and irradiation conditions, Valancia
orange fruits were subje
cted to gamma irradiation at doses of 0.0, 0.5, 1.0, and
1.5 kGy using gamma 60Co irradiator facility. Fruits were kept in a refrigerator
for 18 weeks. Results indicated that physical and sensory properties of Valencia
orange fruits were affected by storage time and irradiation. The overall color
differences were increased and the firmness of fruits and skin were decreased.
The used doses of gamma irradiation increased the overall color differences of
fruit skin. Whereas the fruit firmness, and the sensory properties (aroma,
color, test and firmness) of irradiated Valencia orange fruits were decreased.
The research was carried out during the years 2010 and 2011. The results showed the
following:
The soil's care operations are carried out in the modern and middle old orange
fields and aren't carried out in the old fields ( more than 30 years).
The operations are
embodied in the cultivating operation (facial plowing). The plows are used only in the
modern fields to prepare the seed bed for planting some plants (agronomists) between the
trees classes.
The used plows were effected differently on the orange trees according to plowing
depth and machine sorts. By using the disk harrows with (8) cm depth appeared some roots
on the soil's surface. The trees roots were uprooted and cut up by using the chisel plow
with (20) cm depth and by using the mould board plough with (30) cm depth, but the effect
was so clear by using the mould board plough, that the most of the roots were hurt.
