AB  - Maize (Zea mays L.) is, along with wheat and
rice, one of the most important cereal crops in
the world. The five basic groups of commercially
available maize hybrids are dent, flint, floury,
popping, and sweet maize. The grain color can
also vary from white, yellow, and orange, to red,
blue, purple and brown. The aim of this study
was to investigate the effect of genotype on grain
quality of 33 maize hybrids, including physical
properties and grain chemical composition. The
hybrids were grown in 2022 at the location of Zemun
Polje, Serbia and tested in in the laboratory
of the Department of Food Technology and Biochemistry
of the Maize Research Institute “Zemun
Polje“. Manual dissection of the grains indicated
that the highest content of pericarp fraction
was present in the popcorn genotype ZP 611k
(10.38%), and the lowest in yellow dent genotype
ZP 6066 (5.77%), the germ fraction was predominant
in the sweet hybryd ZP 504su (16,09%),and the endosperm (84.13%) in popcirn genotype
ZP 6119k. The 1000-kernel weight, an important
physical indicator of grain quality, ranged from
120.98 g (popcorn hybrid ZP 617k) to 398.13 g
(yellow dent ZP 7072). Higher 1000-kernel weight
is a preferred wet-milling characteristic because
it is associated with greater starch and protein
yield and lesser yields of fiber. The findings indicate
that the starch, protein, oil, crude fiber,
and ash contents of 33 different maize genotypes
varied between intervals: from 56.79% (sweet
hybrid ZP 504su) to 70.38% (yellow dent hybrid
ZP 4123); from 10.95% (yellow dent ZP 6566) to
13.28% (ZP 504su); from 3.14% (yellow popcorn
ZP 611k) to 7.37 % (ZP 504su); from 1.89% (yellow
dent ZP 457) to 3.45% (early ripening yellow
dent ZP 161); and from 1.39% (yellow dent
ZP 7777) to 1.80% (ZP 161), respectively. The
investigated red kernel genotypes: ZP 3027r and
ZP 5048r, as well as white kernel hybrid ZP 553w
did not stand out significantly regarding the basic
chemical composition, even though our previous
studies showed that red genotypes contain
health-promoting antioxidants – anthocyanins
that provide the red color of the grain. These
findings can be of great importance for future
breeding programs directed toward creating new
and improved genotypes of maize hybrids with
superior grain quality traits intended for different
purposes.

AB  - Whole grain cereals are regarded as key components of nutrition due to their health-promoting properties. Oats (Avena sativa
L.) are naturally gluten-free cereals suited for the gluten-intolerant and individuals with celiac disease. Oats are mostly
utilized as flour or rolled oats in the food sector. Oat flour is produced by milling oat groats or flakes, and it is frequently
used as whole-grain flour. The inedible outer hull of the oat grain is typically removed during harvest and processing. The
hull typically makes up 25–30% of the kernel weight in hulled oats, with minor fluctuation across genotypes. Oats are also
high in dietary fibre, notably β-glucans, which have been shown to provide medical benefits such as lowering cholesterol,
slowing glucose uptake, and lowering plasma insulin levels [1,2]. Furthermore, phenolic acids, flavonoids, carotenoids,
vitamin E, and phytosterols are plentiful in oats [3,4]. Oat hull is high in fibre and low in protein, which lowers the amount
of energy that can be extracted from the kernel. Thus, the use of hulled oats in diets for pigs and poultry is severely constrained,
however, ruminant animals can profit from oats' high levels of fat and fibre compared to other cereal grains. Oats
are currently sent to mills as blends of many oat cultivars with varying quality characteristics, which presents a challenge
for the food industry because it makes it more difficult to forecast the quality of the finished product.
This study aimed to examine the nutritional potentials of the whole grain oat flour and hulls of three oat genotypes with
different hull colours: yellow, brown, and black. Ground oat grains and oat hulls were investigated for their levels of total
phenolic compounds, phenolic acids, β-glucans, antioxidant capacity, and in vitro digestibility. An in vitro multi-step digestion
method was used to determine the potential digestibility of the oat samples for human consumption as a function of
processing variables. The oral, gastric, duodenal, and colon phases of the method proposed by Papillo et al. [5] and modified
by Hamzalıoğlu and Gökmen [6] were carried out without attempting to closely resemble gastrointestinal digestion.
Significant variations were found amongst the analysed samples, particularly when comparing parameter values found in
the hulls to those found in the whole-grain flour. In comparison to flour (841.89-982.08 μg GAE/g d.m.), oat hulls had more
total phenolic compounds (11320.11-24352.48 μg GAE/g d.m.), as well as the phenolic acids: p-coumaric, ferulic, isoferulic,
vanillic, and syringic acid. Ferulic acid was predominant in both the whole grain flour (395.88-589.14 μg/g d.m.) and
the hulls (4987.02-13794.82 μg/g d.m.). The antioxidant capacity was higher in oat hulls, ranging from 42.31 mmol Trolox/
kg d.m., in yellow hulls to 53.16 mmol Trolox/kg d.m. in brown hulls, and from 22.61 mmol Trolox/kg d.m. in black grain, to
25.06 mmol Trolox/kg d.m. in brown whole-grain flour. On the other hand, only 0.03–0.06% of the β-glucan content was
found in the hulls, while it ranged from 4.07% to 5.33% in the whole-grain oat flour samples. The absence of anthocyanins
and proanthocyanidins suggests that these coloured bioactive compounds are not where the oat variants' colour comes
from. The in vitro digestibility of brown whole-grain flour was the highest (48.24%), followed by black (44.72%) and yellow
oat flour (44.54%). The degradability of the ground oat hulls was significantly lower, considering that the in vitro digestibility
ranged from 12.02% in the black genotype to 16.69% in the brown genotype. The examined oat genotypes manifested
a significant potential for use as high-quality food and feed ingredients with nutritional and health-promoting advantages.

AB  - Maize (Zea mays L.) is one of the most important cereal crops in the world, along with wheat and rice. Considering that maize is naturally gluten-free, and safe for persons suffering from celiac disease, or gluten intolerance, wholegrain maize flour is currently trending in the functional food market. Numerous studies related to the distribution of nutritional components among flour fractions with different particle sizes have so far been conducted on barley, sorghum, rice, peas, and soybeans, while the results related to maize are few.
Maize grain of different genetic backgrounds and kernel colors: white dent, yellow popcorn, red dent, and blue popcorn, was used in this study. After grinding maize grain on a stone mill, the wholegrain flour was sifted through three different mesh sieves: 1700, 710, and 212 μm. The content of the major chemical constituents of maize grain was analyzed in each fraction of the sifted wholegrain flour to determine the influence of the particle size after sieving on the distribution of the major nutrients in different fractions. The distribution of the particle sizes among the investigated wholegrain flour samples showed that the medium particle size (710-212 μm) was predominant in all cases, ranging from 60.97% in red flour to 70.64% in white flour, followed by the smallest (≤212 μm) and the largest fraction (1700-710 μm), on average 22.82% and 11.38%, respectively. An increase in the protein content was observed with a decrease in the particle size of the fraction, predominantly in yellow and blue flour, while in white and red flour, the differences among fractions were less significant. The highest increase with the decrease in the particle size of the fraction was manifested by the oil content, followed by the ash content. The crude fiber content in most cases showed a decrease, which is best seen in the example of yellow flour, from 3.59% in the largest particle size fraction to 1.96% in the smallest particle size fraction. The highest starch content was determined in medium particle size fractions of the white (71.86%), red (68.33%), and blue (68.39%), while the highest starch content of the yellow popcorn genotype flour (65.38%) was determined in the largest particle size fraction. The highest ash and oil content was determined in the smallest particle size fraction.
Considering that the digestibility of diet ingredients varies along with the particle size distribution, the next step of the research would be to determine the exact values of the in vitro digestibility of different flour fractions. The fact that the mean particle size of ground maize grains significantly influences nutrient composition, may provide new possibilities of incorporating different wholegrain maize flour fractions in food or feed to meet the specific criteria and dietary needs of different categories of consumers.
AB  - Kukuruz (Zea mais L.) je jedna od najvažnijih žitarica u svetu, pored pšenice i pirinča. S obzirom da je kukuruz prirodno bez glutena i bezbedan za osobe koje boluju od celijakije, ili intolerancije na gluten, potražnja za integralnim kukuruznim brašno je trenutno u porastu na tržištu funkcionalne hrane. Brojna istraživanja koja se odnose na distribuciju nutritivnih komponenata među frakcijama brašna različite veličine čestica do sada su sprovedena na ječmu, sirku, pirinču, grašku i soji, dok su rezultati vezani za kukuruz malobrojni.
U ovom istraživanju korišćeno je zrno kukuruza različite genetske osnove i boje zrna: beli zuban, žuti kokičar, crveni zuban i plavi kokičar. Nakon mlevenja kukuruznog zrna na mlinu sa kamenom, inegralno brašno je prosejano kroz tri različita sita sa otvorima: 1700, 710 i 212 μm. Sadržaj najznačajnijih hemijskih komponenata kukuruznog zrna analiziran je u svakoj frakciji prosejanog integralnog brašna kako bi se odredio uticaj veličine čestica nakon prosejavanja na raspodelu glavnih hranljivih materija u različitim frakcijama. Distribucija veličina čestica među ispitivanim uzorcima integralnog brašna pokazala je da je u svim slučajevima najzastupljenija bila srednja veličina čestica (710-212 μm), koja se kretala od 60,97% u crvenom do 70,64% u belom brašnu, a zatim najsitnija (≤ 212 μm) i najkrupnija frakcija (1700-710 μm), u proseku 22,82% i 11,38%, redom. Uočeno je povećanje sadržaja proteina sa smanjenjem veličine čestica frakcije, pretežno kod žutog i plavog brašna, dok su kod belog i crvenog brašna razlike među frakcijama bile manje značajne. Najveći porast sa smanjenjem veličine čestica frakcije manifestovao se u sadržaju ulja, zatim u sadržaju pepela. Sadržaj sirove celuloze u većini slučajeva je pokazao pad, što se najbolje vidi na primeru žutog brašna, sa 3,59% u najkrupnijoj frakciji na 1,96% u frakciji sa najsitnijim česticama. Najveći sadržaj skroba utvrđen je u frakcijama srednje veličine čestica belog (71,86%), crvenog (68,33%) i plavog (68,39%), dok je najveći sadržaj skroba u brašnu od žutog kokičara (65,38%) utvrđen u frakciji sa najkrupnijim česticama. Najveći sadržaj pepela i ulja određen je u frakciji najmanje veličine čestica.
S obzirom na to da svarljivost hranljivih sastojaka varira zajedno sa distribucijom veličine čestica, sledeći korak istraživanja bi bio utvrđivanje tačnih vrednosti in vitro svarljivosti različitih frakcija brašna. Činjenica da prosečna veličina čestica mlevenog zrna kukuruza značajno utiče na sadržaj pojedinih hranljivih materija, može da pruži nove mogućnosti za upotrebu različitih frakcija integralnog kukuruznog brašna u formulaciji hrane za ljude i životinje kako bi se zadovoljili specifični kriterijumi i prehrambene potrebe različitih kategorija konzumenata.

Sadržaj najznačajnijih hemijskih komponenata kukuruznog zrna analiziran je u svakoj frakciji prosejanog integralnog brašna kako bi se odredio uticaj veličine čestica nakon prosejavanja na raspodelu glavnih hranljivih materija u različitim frakcijama. Distribucija veličina čestica među ispitivanim uzorcima integralnog brašna pokazala je da je u svim slučajevima najzastupljenija bila srednja veličina čestica (710-212 μm), koja se kretala od 60,97% u crvenom do 70,64% u belom brašnu, a zatim najsitnija (≤ 212 μm) i najkrupnija frakcija (1700-710 μm), u proseku 22,82% i 11,38%, redom. Uočeno je povećanje sadržaja proteina sa smanjenjem veličine čestica frakcije, pretežno kod žutog i plavog brašna, dok su kod belog i crvenog brašna razlike među frakcijama bile manje značajne. Najveći porast sa smanjenjem veličine čestica frakcije manifestovao se u sadržaju ulja, zatim u sadržaju pepela. Sadržaj sirove celuloze u većini slučajeva je pokazao pad, što se najbolje vidi na primeru žutog brašna, sa 3,59% u najkrupnijoj frakciji na 1,96% u frakciji sa najsitnijim česticama. Najveći sadržaj skroba utvrđen je u frakcijama srednje veličine čestica belog (71,86%), crvenog (68,33%) i plavog (68,39%), dok je najveći sadržaj skroba u brašnu od žutog kokičara (65,38%) utvrđen u frakciji sa najkrupnijim česticama. Najveći sadržaj pepela i ulja određen je u frakciji najmanje veličine čestica.
S obzirom na to da svarljivost hranljivih sastojaka varira zajedno sa distribucijom veličine čestica, sledeći korak istraživanja bi bio utvrđivanje tačnih vrednosti in vitro svarljivosti različitih frakcija brašna. Činjenica da prosečna veličina čestica mlevenog zrna kukuruza značajno utiče na sadržaj pojedinih hranljivih materija, može da pruži nove mogućnosti za upotrebu različitih frakcija integralnog kukuruznog brašna u formulaciji hrane za ljude i životinje kako bi se zadovoljili specifični kriterijumi i prehrambene potrebe različitih kategorija konzumenata.",

AB  - Maize (Zea mays L.) is one of the most important cereal crops in the world, along with wheat and rice. Considering
that many physical and chemical factors influence the digestibility of food and feed ingredients, this study aimed to
determine the effect of particle size on the in vitro digestibility and nutritional properties of various wholegrain maize
flour fractions. Maize grains of various genetic backgrounds and kernel colours were used in this study, namely, white
dent, yellow popcorn, red dent and blue popcorn. After grinding maize grains on a stone mill, the wholegrain flour was
dry-sieved through three mesh sieves: 1700 μm, 710 μm and 212 μm. The medium particle size fraction (710–212 μm)
was dominant. The in vitro digestibility testing showed that the powder fraction (< 212 μm) was the most digestible in
all investigated samples, while the coarse fraction was the least digestible. The yellow popcorn genotype showed the
highest overall digestibility. An increase in the protein content was observed with a decrease in the particle size of the
fraction. The findings of this study offer new possibilities for incorporating various wholegrain maize flour fractions in
food or feed to meet the specific needs of various categories of consumers.

AB  - The main aim of this study was to assess the effect of the
micronization process applied on cereals and legumes, as feed components, on
the efficiency of feed conversion, digestibility, and daily gain of weaned piglets.
The results showed that the digestibility of the investigated micronized maize
and wheat flakes was higher than that of the respective raw grains. The
digestibility of the feed mixture prepared with micronized cereals and legumes
was higher (84.74%) than that of the commercial feed mixture (80.27%). The feed
mixture prepared with micronized cereals and legumes manifested beneficial
effects on weaned piglets' daily gain, feed conversion, and digestibility in the
feeding trial.

AB  - Lignocellulosic biomass represents the most abundant renewable
material in the world, whereas agricultural residues, including those from maize
cultivation, comprise a significant fraction of the total plant waste that can be
repurposed for various applications. Lignocellulosic feedstocks are non-edible
and consist mainly of: cellulose, hemicellulose, and lignin, along with extractive
compounds. Pretreatment is required to separate the lignocellulosic biomass into
its constituents for efficient utilization. Even after extensive research and
development of numerous techniques, pretreatment remains one of the most
expensive phases in converting lignocellulosic biomass into biobased products.

AB  - The contemporary age has imposed numerous issues and obstacles worldwide that range from poverty, overpopulation, hunger, and political crisis to global warming, and other environment-bound problems. Furthermore, the interest in food safety and food waste management is gaining momentum. A potential health hazard stems from the presence of acrylamide (AA), a mutagen and Group 2A carcinogen, in food. When food is heated to a temperature above 120 °C during commercial or home cooking, free asparagine (Asn) and reducing sugars undergo the Maillard reaction, which is where AA primarily develops. According to research, foods produced from cereal grains may account for 20–60% of all AA intake. Implementation of a "field-to-fork" strategy that interconnects the food researchers and policymakers with the whole supply chain from cereal growers and the food industry with the consumers, safer and healthier cereal-based food production can be achieved.
