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.
