AB  - The cold pressed sunflower oil is obtained by mechanical extraction from the seed which is pressed
with a different content of the hull. The content of the hull in the seed is conditioned by the type of
hybrid and affects the quality and yield of cold pressed oil as well as the quality of the obtained
cake. In addition to the contents of the hull, the yield of the pressing is influenced by the type of raw
material. ie the content of the oil in the material for pressing, then the preparation of the material,
the granulometric composition, residual impurities, etc. The structure and power of the presses, as
well as the pressing conditions (pressure, temperature, duration of the process, the content of the oil
in the cake, the moisture content of the raw material, etc.), also affect the effectiveness of pressing
(yield).
In this paper, the exploitation of the pressing (yield value) of the latest oil hybrids of the secondary
filial (F2) generation grown on the territory of the Republic of Serbia was examined. The yield
value in five different oil hybrids (Dusko, Orfej, NS Konstantin, NS Ronin and NS Horizont) was
calculated on the basis of the oil content of seed and cake obtained after pressing. The content of the
oil was determined according to SRPS EN ISO 659:2011, while the moisture content was made
according to SRPS EN ISO 665:2008.
The seed oil content ranged from 32.52 + 2.16 to 41.66 + 2.08 %, while the moisture content in
these seeds ranged from 5.92 + 0.04 to 6.08 + 0.08 %. In the obtained cakes the content of oil was
determined from 14.80 + 0.05 to 17.64 + 0.01 %, while in the same cakes the moisture content was
in the range of 6.92 + 0.01 to 7.84 + 0.03 %. Of the examined samples, the maximum yield value
was determined for the sample of NS Konstantin and amounted to 75.61 + 1.99 %, while the lowest
yield value of 55.37 + 4.41 % was determined for the NS Horizont sample.

AB  - Content of the oxidation products is very important parameter of oil quality and oxidative
stability, ie. shelf life. In order to improve shelf life of oils, the breeders create new
sunflower hybrids with altered fatty acid composition as well as the content of minor
components that contribute to oxidative stability of oil (tocopherols, sterols, phenolic
compounds, etc.).
In order to examine the oxidative stability of the oil, sunflower seed oils of the same
latest hybrids of the secondary filial (F2) generation grown on the territory of the
Republic of Serbia and Argentina were analized. Samples were tempered at 63 + 2 °C
for a period of 8 days. The content of primary and secondary oxidation products was
monitored through the peroxide (PV) and anisidine values(p-AnV, as well as the content
of conjugated dienes (CD) and trienes (CT). After the 4" and 8" day, the samples were
taken and analysed and compared with the initial samples.
Based on the content of the resulting oxidation products the best oxidative stability
showed the oil seeds NS Horizont grown on the territory of Serbia. In this sample values
of the tested parameters of oxidative stability in the initial sample were PVinitial = 1.99 +
0.06 mmol/kg, p-AnVinitiar = 0.08 + 0.01 and after 8 days of testing: PVéin day = 30.32 +
0.03 mmol/kg, p-AnVsth day = 2.05 + 0.01. The same sample grown in Argentina showed
significantly poorer results: PVinitial = 2.00 + 0.07 mmol/kg, p-AnVinitial = 1.13 + 0.00 and
PVath day = 73.45 + 4.31 mmol/kg, p-AnVath day = 3.14 + 0.01.

AB  - Sunflower (Helianthus annuus L.) is an important oilseeds crop among the four major
oilseeds crop cultivated in the world viz., soybean, brassica, sunflower and groundnut. Two
types of sunflower are grown viz., gil seed purpose and non- oil seed sunflower for
commercial market. Non-oilseed sunflower is known as confectionery sunflower and their
seed generally is larger than that of the oilseed types and has a lower oil percentage with
high protein and sugar content. Vegetable oils are significant sources of antioxidants in
human nutrition. Natural antioxidants present in oils have obtained substantial attention
because of their health and nutritional effects. Plants produce of antioxidant compounds
such as tocopherols and tocotrienols to prevent oxidation of the susceptible substrate.
Antioxidant properties the tocopherols content of oils can give human health benefits like
modulating cancer, cardiovascular diseases and a protective effect by lowering LDL
cholesterol by inhibiting cholesterol biosynthesis. Over the last few years, increased interest
for natural antioxidant in cold-pressed plant oils has been observed since they have better
nutritive properties in comparation to refined ones. The aim of this study was to investigate
tocopherols composition (a-, B-, y- tocopherols) in selected 10 cold-pressed sunflower oils
obtained from confectionary sunflower hybrids cultivated in Serbia (2017 harvest).
Quantification of tocopherols was carried out using high performance liquid
chromatographyon a column Nucleosil 100-5 NHz with fluorescence detection (Acx=280 nm,
hem=340 nm). The mobile phase was n-hexane/ethyl acetate (70/30, v/v) with a flow rate of
1 ml/min. Total tocopherols content in cold-pressed sunflower oils ranged from 413.13
mg/kg in NS-H-6791 hybrid to 720.99 mg/kg in NS-H-6488 hybrid. Major vitamers for those
tested hybrids was a- tocopherol. The results have shown that there were significant
differences in tocopherols composition and content among the hybrids, indicating the great
genetic potential for improvement.

AB  - Catechin is a flavonoid compound with polyphenolic structure naturally occurring in plants, fruits, tea, red
wine and cacao products. Many beneficial effects are associated with catechin consumption such as
antioxidant, anticarcinogenic, anti-inflammatory, antiatherogenic, antibacterial and antiviral activity.
Determination of catechin is typically based on the use of high-performance liquid chromatography, but also
methods such as spectrophotometry and capillary electrophoresis are reported.
In this work we investigated the use of different modifications of a carbon paste electrode (CPE) for
voltammetric determination of catechin. The reason for introducing a modifier into the carbon paste was to
increase the sensitivity of the voltammeircic techniques, due to the catalytic effect of the modifier on the
electrode processes. Multi-walled carbon nanotubes (MWCNTs), antimony(Ill) oxide and bismuth
nanoparticles are investigated as bulk modifiers for preparation of CPE with concentration of 5% (w/w).
Electroanalytical measurements are performed in 0.1 M phosphate buffer pH 7.0 using cyclic voltammetry
and square wave voltammetry, in the concentration range from 1 to 20 mg/dm* of catechin.
Two oxidation peaks of catechin are observed for all studied modified CPEs and bare CPE, with significantly
higher intensity of the first peak. The results also showed improvement of sensitivity by using the modified
CPEs in comparison to unmodified CPE. The application of MWCNTs as a modifier contributed to the
highest sensitivity for catechin determination in relation to the other modifiers. These preliminary results
show that MWCNTs modified CPE can be used as a very sensitive sensor for catechin determination in real
samples.

AB  - Blending vegetable oils of different composition and properties is one of the simplest methods for
creating new specific products with the desired properties, which increases their commercial
application and improves their nutritional quality.
The effect of blending vegetable oils on tocopherols and carotenoids content was examined. Refined
sunflower seed oil (S) and cold pressed flaxseed oil (F) were used in the experiment. These oils are
blended in three different content of mass: sample 70S:30F (70% S and 30% F), sample 50S:50F
(50% S and 50% F) and sample 30S:70F (30% S and 70% F).
The results showed significant differences in the content of total tocopherols and total carotenoids
between the two oils used for the preparation of three blended oils. Refined sunflower seed oil
contains higher amounts of tocopherols and fewer amounts of carotenoids compared to cold pressed
flaxseed oil in which the content of tocopherols is lower and the content of carotenoids is higher. In the
obtained blends of edible vegetable oils, the content of total tocopherols ranged from 387.96 to 447.83
mg/kg while the determined total carotenoids content (as B-caroten) ranged from 3.11 to 5.63 mg/kg.
By blending refined oil of sunflower seed and cold pressed oil of flax-seed, the balance of the
parameters studied is contributed. The research in the work showed that the blending of vegetable oils
provides the possibility of modulating their composition, and therefore of nutritive quality.

AB  - The confectionary/non-oil seed of sunflower hybrids is characterized by a higher content of the hull, which is thicker than the oil seed hybrids of sunflower. These seeds can be of different size and shape, with a hull not completely black. The aim of this study is to examine the dimensions of confectionary seeds of the latest NS sunflower hybrids. The results of the analyzed seed samples of the latest hybrids of second filial (F2) generation (NS-H-6792, NS-H-6489, NS-H-6311) are compared with the results of already-used hybrid seeds (Cepko). Equivalent diameter and linear dimensions of seed are characterized by Malik and Saini, 2016. The highest specific value of the equivalent diameter was 8.25±0.60 mm (NS-H-6792) and the smallest was 7.90±0.30 mm (NS-H-6311). Only 24.33% of the measured seeds were between 15.00 and 15.99 mm long, which is the most frequent length interval. The average seed width is from 7.00 to 7.99 mm (44.33%), while the average seed thickness is from 4 to 4.99 mm, which was measured in 46.67% of examined seeds. From the above results of the linear dimensions it can be concluded that the seeds are the most different in length, while the distribution of the results by width and thickness is less.

Only 24.33% of the measured seeds were between 15.00 and 15.99 mm long, which is the most frequent length interval. The average seed width is from 7.00 to 7.99 mm (44.33%), while the average seed thickness is from 4 to 4.99 mm, which was measured in 46.67% of examined seeds. From the above results of the linear dimensions it can be concluded that the seeds are the most different in length, while the distribution of the results by width and thickness is less.",

AB  - Because of the favorable amino acid composition of sunflower protein and low content of antinutritive components, the confectionary/non-oil sunflower seed is increasingly gaining in importance. This is why there is a need for increasing the number of this type of hybrids. Breeding new hybrids of different characteristics are obtained. In order to investigate the composition of the seed, three samples of the latest NS hybrids of second filial (F2) generation (NS-H-6792, NS-H-6489, NS-H-6311) were analyzed and compared with the results of the hybrid seed already-used (Cepko). The content of moisture was determined according to SRPS EN ISO 665, 2008, the content of the oil according to SRPS EN ISO 659, 2011, while the mass of 1000 seeds and the content of hull and kernels were made according to Karlović & Andrić, 1996. The moisture content ranged from 5.75±0.00% in the sample NS-H-6792 to 6.57±0.03%, in the sample NS-H-6489. The oil content was in the range of 25.62±0.22%, found in the sample NS-H-6311 to 23.12±0.16%, found in the sample NS-H 6489. The highest content of the hull was found in the NS-H-6792 sample, 46.74±0.80%, while the smallest content of the hull was found in the sample NS-H-6311 and amounted to 41.91±0.71%.

AB  - Vegetable oils rich in antioxidant are of great interest in the food industry as they decelerate oxidative degeneration of lipids and therefore promote the quality as well as the nutritional value of food. Sunflower (Helianthus annuus L.) is one of the most abundant annual crops in the world that is grown for edible oil which is a good source of bioactive compounds. Tocopherols belong to the most important bioactive compounds in oil which have many health benefits for human. These compounds preserve oil from peroxidation by scavenging lipid peroxyl radicals. In humans, tocopherols play an important role as vitamin E, contributing to maintaining the immune system and delaying the pathogenesis of a variety of degenerative diseases. Over the last few years, increased interest for natural antioxidant in cold‐pressed plant oils has been observed since they have better nutritive properties in comparison with refined ones. In this work, three cold-pressed sunflower oils obtained from sunflower hybrids cultivated in Serbia (2017 harvest) were studied for their contents. Quantification of tocopherols was carried out using high performance liquid chromatography on a column Nucleosil 100-5 NH2 with fluorescence detection (λex=280 nm, λem=340 nm). The mobile phase was n-hexane/ethyl acetate (70/30%v/v) with a flow rate of 1 ml/min. The relative retention value and maximum values of absorption at the given relative retention time were used to identify and confirm the presence of tocopherolsin injection volume of 20 μl solution samples obtained by diluting of oil (300 µL) in n-hexane (2 ml). This research verified the dominant presence of α-tocopherol in cold-pressed sunflower oils. The content of α-tocopherol ranged between 497.40 mg/kg oil in NS Oliva hybrid and 691.46 mg/kg oil in NS Romeohybrid. The results have shown that there were differences in content of tocopherols among tested hybrids, indicating the great genetic potential for improvement.

AB  - Sunflower seed cake is remaining after isolation of oil from sunflower seeds and practically
represents a waste from production of cold pressed sunflower oils. This waste product is
consider as a viable potential source of various natural compounds and can be exploited for
the production of new products and isolation of valuable substances such as biologically
active compounds and nutraceuticals. In addition, isolation of biologically active substances
from food waste represents the way for recycling and may be economically attractive as well.
Flavonoids represent a group of polyphenol compounds with a high antioxidant power. These
phytochemicals are known to reduce many chronic diseases such as cardiovascular diseases,
heart diseases, diabetes, obesity and certain cancer [1]. In this work we investigated the
flavonoids content in seven sunflower seed cakes coming from cold pressed oil production.
Flavonoids are extracted by using 80% ethanol and ultrasound-assisted extraction at 30°C for
10 minutes. Total flavonoid content is determined by a colorimetric method [2]. The results
showed that sunflower seed cakes contained significant amounts of total flavonoids. The total
flavonoids content is found to be in the range from 12.3 to 24.6 mg of catechin equivalent/g.
The results proved that sunflower seed cakes obtained from cold pressed oil production
represent valuable by-product and can be used as a raw material for isolation of bioactive
flavonoids which could be further applied for development of various functional foods.

tip | konzumni tip. Uljani tip suncokreta se proizvodi za dobijanje jestivog biljnog ulja, dok
se konzumni suncokret odlikuje manjim sadrzajem ulja i visokim sadrzajem proteina i drugih
bioloski aktivnih jedinjenja, i koristi se preteZno za lIjudsku ishranu usled visoke hranljive

senzorna svojstva i sadrzi ocuvane bioaktivne komponente koje poti€u iz semena
suncokreta. Usled odsustva rafinacije, ova ulja su specificna po svom izgledu, boji, mirisu i
ukusu, hemijskom sastavu, nutritivnoj vrednosti i odrzivosti. Nakon mehanickog izdvajanja
ulja presovanjem semena zaostaje pogaca koja prakti¢no predstavija otpad iz prehrambene
industrije i najéeée se koristi za ishranu Zivotinja. Pored visokog sadrzaja proteina, pogaca
sadrizi znaéajne koliéine biologki aktivnih jedinjenja, te moze predstavijati polaznu sirovinu

ekstrakcije“ i imaju za cilj zastitu Zivotne sredine i opsteg zdravlja Ijudi. Generalno, koncept
zelenih tehnika podrazumeva smanjenje ili eliminaciju primene toksi¢nih rastvaraca za
ekstrakciju uz istovremeno povecanje iskoriscenja procesa kroz manji utrosak energije,
manje generisanje otpada, kra¢e vreme trajanja procesa i manje angazovanje operatera.",

AB  - The study deals with mineral characterisation of natural waters from South-East Serbia. The contents of aluminium, arsenic, calcium, cadmium, cobalt, chromium, cooper, iron, potassium, magnesium, manganese, sodium, nickel, lead and zinc were analysed in spring, ground and river waters by inductively coupled plasma-atomic emission spectrometry (ICPAES) technique. The study area was in the Southern Serbia, and included slopes of Rtanj, Ozren, Bukovik, Vrdenik and Čemernik mountains, and the valley of South Morava. Obtained contents were compared with Serbian regulations on the quality of water for human use, and directive of World Health Organization (WHO) for maximum allowed concentrations of chemical substances. High contents of macro-elements, namely calcium, magnesium and potassium, were detected in several spring and ground water samples which are believed to be due to direct influence of rock minerals. Some water samples contained iron, manganese and copper in concentration up to 168.3, 8.10 and 14.9 μg dm-3, respectively, but within the permissible limits. Other heavy metals were not detected in analysed samples. Based on the derived results, tested ground and spring water samples have significant potential to be used as sources for the production of bottled water, but further investigations are necessary. Additional investigations have to be focused on complete physical, chemical and microbiological assessments of water resources. Systematic hydrogeological assessment also should be performed in all seasons. In the meantime, precautionary measures should be immediately taken to protect and preserve these water resources.
AB  - Ovaj rad predstavlja analizu kvaliteta prirodnih voda iz jugoistočne Srbije. Sadržaj arsena, aluminijuma, kalcijuma, kadmijuma, kobalta, hroma, bakra, gvožđa, kalijuma, magnezijuma, mangana, natrijuma, nikla, olova i cinka je određivan u izvorskim i podzemnim vodama, kao i u rečnoj vodi. Analiza navedenih elemenata je izvedena ICP-AES tehnikom. Analizirani su uzorci voda iz oblasti jugoistočne Srbije, uključujući područja planine Rtnja, Ozrena, Bukovika, Vrdenika i Čemernika, kao i područje doline reke Južne Morave. Određeni sadržaji analiziranih elemenata su poređeni sa važećim pravilnicima Republike Srbije i preporukama Svetske zdravstvene organizacije (SZO). Visoki sadržaj makro-elemenata, odnosno kalcijuma, magnezijuma i kalijuma uočeni su u izvorskim i nekoliko uzoraka podzemnih voda, što može biti posledica direktnog uticaja magmatskih stena. Pojedini uzorci voda su sadržali nešto više sadržaje gvožđa, mangana i bakra u koncentraciji do 168,3, 8,10 i 14,9 μg dm-3, redom, ali u granicama propisanim Pravilnikom i u skladu da preporukama SZO. Ostali teški metali nisu detektovani u ispitivanim uzorcima. Na osnovu dobijenih rezultata se može zaključiti da testirani uzorci podzemnih i izvorskih voda imaju značajan potencijal u smislu proizvodnje flaširane vode, uz neophodna dodatna istraživanja. Dodatna istraživanja bi trebalo usmeriti na kompletnu hemijsku analizu i ispitivanje fizičkih i mikrobioloških karakteristika uzoraka voda. Pored toga, neophodno je sprovesti sistematsko hidrogeološko ispitivanje izdašnosti podzemnih i izvorskih voda tokom svih godišnjih doba. U međuvremenu treba preduzeti mere predostrožnosti kako bi se ovi vodeni resursi zaštitili i očuvali.
