AB  - Sunflower seeds (Helianthus annus L.) are the most represented oilseed in Serbia. During
the oil production process, the seeds are partially and/or completely dehulled. Sharma et al. (2009)
found that, in addition to the moisture content of the seed, the effect of dehulling is also significantly
influenced by seed firmness. The dehulling effect increases with decreasing seed firmness. This
paper examines the technological characteristics of sunflower seeds of selected hybrids (true density,
content of hull in seeds and mass of 1000 grains expressed on dry matter), based on which a
mathematical model for prediction of seed firmness was made. The tested samples are oily hybrids,
grown on the territory of Serbia in 2017, namely: NS Horizont, Sumo 2 OR, NS Sumo Sjaj, NS
Samuraj CLP, NS Smaragd CLP. True density, content of hull in seed, and mass of 1000 grains
expressed on dry matter were made according to Karlovi¢ and Andri¢ (1996), while seed firmness
was made using Texture Analyzer TA.HD Plus (Stable Micro Systems, Godalming, U.K.). Firmness
of the samples tested ranged from 5522.67 + 765.40 to 6889.10 + 1220.62 g, true density from 753.92 +
18.23 to 877.33 + 0.93 kg m°%, hull content of 47.54 + 0.13 to 55.15 + 0.87% and a mass of 1000 grains
expressed on dry matter of 48.83 + 0.80 to 57.10 + 2.52 g. Model validation was also performed, and
based on the statistical validation parameters, it is concluded that it is possible to predict seed
firmness based on its technological characteristics.

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  - 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  - 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.

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  - 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  - Oxidative stability, i.c. shelf life of oil is related to the degree of the oxidative changes
in the amount of the resulting primary and secondary oxidation products of unsaturated fatty
acids. In order to improve oxidative stability, i.e. oil shelf life, sunflower hybrids with altered
fatty acid composition have been created, i.e. significantly higher oleic acid (C18:1) content,
even over 90% w/w, relative to the linoleic type with 25-30% w/w of oleic and 60-65% w/w
of linoleic acid (C18:2). In order to examine the oxidative stability of the oil, three samples of
sunflower seed oil NS hybrids (NS Oliva, NS Horizont and NS Romeo) of different fatty acid
composition were analyzed. Samples were exposed to moderate temperatures (6342°C) over a
period of 8 days. Changes in the content of primary and secondary oxidation products based
on changes in peroxide (PV) and anisidine (p-AnV) values, as well as changes in the content
of conjugated dienes and trienes, were observed. The highest oxidative stability was observed
in the oleic type oil sample. In this sample the determined values of the tested parameters of
oxidative stability, after 8 days, were PV=4.85 mmol/kg and p-AnV=0.65, compared to the
initial sample (PV=0.36 mmol/kg and p-AnV=0.57). The greatest oxidative changes occurred
in the oil sample with the lowest content of oleic and the highest content of linoleic acid, as
indicated by the PV=73.22 mmol/kg and p-AnV=3.60, after 8 days, in relation to PV=2.16
mmol/kg and p-AnV=0.50 in the initial linoleic type oil sample.

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.

AB  - Seme suncokreta se odavnina koristi u Ijudskoj ishrani i u danaSnje vreme predstavlja jednu
od najvise gajenih uljanih kultura u svetu. Razlikuju se dva tipa suncokreta koji se gaje, uljani
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
vrednosti. U poslednje vreme, mogucnost proizvodnje ulja od konzumnog suncokreta je
predmet interesovanja kako u nauénim krugovima, tako i u krugovima proizvodaga i
preradivaéa. Ulja iz konzumnog suncokreta dobijaju se cedenjem, tj. primenom mehanickih
presa i delovanjem sile na seme. Nerafinisano, hladno cedeno ulje poseduje karakteristi€na
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
za dobijanje ekstrakata koji sadrze visoko vredna jedinjenja i koji bi dalje mogli da se koriste
za obogacivanje prehrambenih proizvoda ili kao dodaci u farmaceutskim proizvodima.
Polifenoli, pored ostalih vaznih jedinjenja, predstavijaju veoma znacajnu grupu supstanci
koje se nalaze u konzumnom suncokretu. Unosenje ove vrste jedinjenja hranom ima
visestruke efekte na |judsko zdravije, prvenstveno povezanih sa njihovom izrazenom
antioksidativnom aktivnoscu i sposobnosti eliminacije slobodnih radikala. Konzumacija

ekstrakcije. Uobiéajeni postupci ekstrakcije su nedovoljno efikasni i ne omogucavaju visoko
iskoriscenje biljnog materijala, zahtevaju upotrebu zna¢ajno vecih kolicina organiskih
rastvaraca, uz istovremeni veliki utroSak energije usled dugotrajnih procesa ekstrakcije,
neophodnosti zagrevanje i mesanja. U poslednje vreme se mnogo cesce koriste moderne

manje generisanje otpada, kra¢e vreme trajanja procesa i manje angazovanje operatera.

abstract = "Seme suncokreta se odavnina koristi u Ijudskoj ishrani i u danaSnje vreme predstavlja jednu
od najvise gajenih uljanih kultura u svetu. Razlikuju se dva tipa suncokreta koji se gaje, uljani
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
vrednosti. U poslednje vreme, mogucnost proizvodnje ulja od konzumnog suncokreta je
predmet interesovanja kako u nauénim krugovima, tako i u krugovima proizvodaga i
preradivaéa. Ulja iz konzumnog suncokreta dobijaju se cedenjem, tj. primenom mehanickih
presa i delovanjem sile na seme. Nerafinisano, hladno cedeno ulje poseduje karakteristi€na
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
za dobijanje ekstrakata koji sadrze visoko vredna jedinjenja i koji bi dalje mogli da se koriste
za obogacivanje prehrambenih proizvoda ili kao dodaci u farmaceutskim proizvodima.
Polifenoli, pored ostalih vaznih jedinjenja, predstavijaju veoma znacajnu grupu supstanci
koje se nalaze u konzumnom suncokretu. Unosenje ove vrste jedinjenja hranom ima
visestruke efekte na |judsko zdravije, prvenstveno povezanih sa njihovom izrazenom
antioksidativnom aktivnoscu i sposobnosti eliminacije slobodnih radikala. Konzumacija
hrane bogate antioksidantima smanjuje inflamaciju i nivo oksidativnog stresa kod €oveka.??
Takode oni pozitivno uti€u na celokupan kardiovaskularni sistem i proces starenja.
