“…Variations in the ratios between phytate, β-carotene and the mineral nutrients could indicate possible bio-availability of the mineral nutrients (Walter Lopez et al, 2002;Dragičević et al, 2013), with increased tendency of availability with decreasing ratio.…”

Deficiencies of mineral elements in human nutrition could be surpassed by crop fortification. One of the prevalent measures of fortification is foliar fertilization. The aim of this study was to determine the content and availability of the mineral nutrients Mg, Fe and Zn, together with phytate, as an anti-nutritive factor, and β-carotene as a promoter of mineral nutrient availability in grain of two soybean cultivars (Nena and Laura) treated with different non-standard foliar fertilizers (mainly based on plant extracts). Generally, a negative correlation between Fe and phytate indicated that factors which decrease phytate and increase β-carotene could be primarily responsible for Fe utilization by humans and animals. Zlatno inje (based on manure) had the highest impact on increasing the grain yield and decreasing the ratios between phytate and mineral elements in Nena grain, while for Laura, it was generally Zircon (based on an extract of Echinacea purpurea L), increasing also availability of mineral elements.Keywords: β-carotene, fortification, iron, magnesium, phytate, zinc 356Journal of Central European Agriculture, 2016, 17(2), p.356-368 DOI: 10.5513/JCEA01/17.2.1715 Rezime Nedostatak mineralnih elemenata u ljudskoj ishrani se može prevazići fortifikacijom useva. Najčešće korišćena mera je upotreba folijarnih đubriva. Istraživanje ima za cilj da utvrdi sadržaj i pristupačnost mineralnih nutrienata Mg, Fe i Zn, zajedno sa fitatom kao anti-nutritivnim faktorom i β-karotenom kao promoterom koji utiču na pristupačnost mineralnih nutrienata u semenu dve sorte soje (Nena i Laura) tretiranih različitim folijarnim đubrivima (uglavnom na bazi biljnih ekstrakata). Negativna korelacija između Fe i fitata ukazuje da bi faktori koji smanjuju sadržaj fitata i povećavaju sadržaj β-karotena mogli biti primarno odgovorni za Fe usvajanje kod čoveka i životinja. Zlatno inje (đubrivo na bazi stajnjaka) je pokazalo najveći uticaj na povećanje prinosa i smanjenje odnosa fitata i mineralnih elemenata u zrnu Nene, dok je kod Laure najveći uticaj ispoljio Cirkon (na bazi ekstrakta Echinacea purpurea L), povećavajući takođe pristupačnost minerlanih elemenata.Ključne reči: β-karoten, cink, fitat, fortifikacija, gvožđe, magnezijum Detaljan rezime Nedostatak mineralnih elemenata u ljudskoj ishrani se može prevazići povećanjem njihovog sadržaja putem fortifikacije. Folijarna primena nutrienata omogućava njihovu bržu penetraciju kroz list, uz brži odgovor biljke. Biljna hrana može da sadrži antinutriente (kao što je fitat) koji onemogućavaju apsorpciju i iskorišćenje mineralnih nutrienata od strane monogastričnih organizama, kao i promotere (kao što je β-karoten) koji povećavaju pristupačnost mineralnih nutrijenata. Cilj ogleda je bio da se odredi sadržaj i potencijalna pristupačnost mineralnih nutrienata Mg, Fe i Zn, zajedno sa fitatom, kao anti-nutritivnim faktorom i β-karotenom, kao promoterom u soji tretiranoj različitim nestandardnim folijarnim đubrivima tokom 2009., 2011. i 2012. godine.U eksperimentu su korišćene sorte s...

“…Phytic acid is a key anti-nutrient because it is abundant in cereals, legumes and oil seeds where it binds all the principal mineral nutrients and sequesters them into stable complexes that cannot be absorbed (Lopez et al 2002). The amount of phytic acid in seeds can be reduced by silencing genes involved in its biosynthesis, such as myo-inositol-1-phosphate synthase (Nunes et al 2006) or 1D-myo-inositol 3-phosphate synthase (Kuwano et al 2009).…”

Malnutrition is a prevalent and entrenched global socioeconomic challenge that reflects the combined impact of poverty, poor access to food, inefficient food distribution infrastructure, and an over-reliance on subsistence mono-agriculture. The dependence on staple cereals lacking many essential nutrients means that malnutrition is endemic in developing countries. Most individuals lack diverse diets and are therefore exposed to nutrient deficiencies. Plant biotechnology could play a major role in combating malnutrition through the engineering of nutritionally enhanced crops. In this article, we discuss different approaches that can enhance the nutritional content of staple crops by genetic engineering (GE) as well as the functionality and safety assessments required before nutritionally enhanced GE crops can be deployed in the field. We also consider major constraints that hinder the adoption of GE technology at different levels and suggest policies that could be adopted to accelerate the deployment of nutritionally enhanced GE crops within a multicomponent strategy to combat malnutrition.

“…An optimum rate of K fertilization increases number of productive tillers, number of grain per spike, 1000 grain weight, grain yield, and protein content of wheat (Alam et al, 2009). Phytic acid (phytate) is the main phosphorus storage form in most cereals, legumes and nuts (Lopez et al, 2002). It is considered as an anti-nutritional factor that complex with proteins and chelates with some nutritionally important micronutrients (Fe, Zn, Mg, and Ca) and resulting in a significant decrease in the bioavailability of these nutrients (Raboy, 2001).…”
