“…The costs include Zn fertilizer, agricultural equipment (motorized sprayer and water tank), and labor and extension services, but do not include social marketing when the foliar Zn application was conducted alone. In most practical situations, the combined foliar application of Zn fertilizer plus pesticide is employed (Ram S-W single wheat plantation, W-M wheat-maize rotation, W-R wheat-rice rotation a,b Initial and improved grain Zn content under the pessimistic scenario was based on field studies in China (Zhang 2012), while grain Zn content under the optimistic scenario was based on field studies in multiple countries c Based on 85 % flour yield (Tang et al 2008) d Based on Bouis et al (2011) e Based on and updated from genetic biofortification studies (Stein et al 2005;Stein et al 2007;De Steur et al 2012). Here, the basic assumption of coverage rate is that all consumers replace a certain percentage (20 or 60 %) of their consumption with the biofortified wheat and continue to consume some unfortified wheat in parallel, because biofortified and non-biofortificated wheat cannot be distinguished based on appearance (Stein et al 2005) f Based on the China National Nutrition and Health Survey 2002 (Chai 2009) g Based on the WHO recommended nutrition intake levels for Zn in developing countries (Allen et al 2006) et al , 2016Wang et al 2015).…”

Biofortification is a strategy for overcoming human zinc (Zn) deficiency, especially in rural areas of developing countries. Actually, biofortification by foliar Zn application has been demonstrated at small scale, but not at large scale due to the absence of economic analysis. Therefore, here, we conducted the first cost-effectiveness analysis using the method of "disability-adjusted life year" measuring the health burden. We thus quantified the cost of agronomic biofortification of wheat with Zn in three major wheat-growing regions of China. Our results show that the current annual health burden due to human Zn deficiency, defined as numbers of disabilityadjusted life years lost, is 0.21 million years for the region under single wheat plantation, 0.79 million years for the region under wheat-maize rotation, and 0.38 million years for the region under wheat-rice rotation. Comparing with traditional wheat diets in these three regions, the consumption of agronomically Zn-biofortified wheat diets could increase the daily Zn intakes of infants and children under 5 years of age. These increased daily Zn intakes consequently reduce the health burden due to human Zn deficiency in these regions by up to 56.6 %.

“…Najveći deo fi tata u pšeničnom zrnu se nalazi u aleuronskom omotaču i tokom mlevenja većina aleuronskih ćelija ostaje sa česticama perikarpa, pa je to razlog što je najveći deo fi tata koncentrisan u frakcijama mekinja (Tang et al 2008) i do 5 puta više nego u brašnu (Zečević et al 2007). Celo pšenično zrno sadrži 0,3% do 0,4% fi tata dok mekinje sadrže do 5% (O'Dell et al 1972).…”

Izvod: Potreba za oplemenjivanjem pšenice na nizak sadržaj fi tinske kiseline proistekla je iz njene uloge antinutritivnog faktora koji vezujući mineralne elemente (Ca, Zn, Fe, Mn, Cu, kao i P) dovodi do njihovog nedovoljnog iskorišćavanja. Neiskorišćeni fosfor u kompleksu sa fi tinskom kiselinom se preko lanca ishrane nepreživara (živina, svinje, ribe) izlučuje u spoljašnju sredinu i uzrokuje zagađivanje vodenih ekosistema. Razvijene su brojne indirektne (spektrofotometrijske) i direktne (HPLC -High Performance Liquid Chromatography) metode za brzo i pouzdano utvrđivanje sadržaja fi tinske kiseline u zrnu pšenice. Brojna istraživanja u svetu su pokazala da se sadržaj fi tinske kiseline kreće od jedan do nekoliko procenata suve mase semena i 50% do 85% ukupnog fosfora u semenu. Utvrđena je značajna genetička varijabilnost sadržaja fi tinske kiseline i fi tatnog fosfora u zrnu sorata i linija pšenice u različitim uslovima spoljašnje sredine. Oplemenjivanjem je dobijen i mutant pšenice (Triticum aestivum L.) Js-12-LPA, za osobinu niskog sadržaja fi tinske kiseline (Low phytic acid).

Plants are the first step of a metal's pathway from the soil to heterotrophic organisms such as animals and humans, so the content of metallic trace elements in edible parts of a plant represent available load of these metals that may enter the food chain through plants. Among metal elements, Cu, Fe, Mn, and Zn are micronutrients as they are essential in trace amounts for physiological processes in living organisms and therefore are a significant component of the soil-plant-food continuum. Billions of people around the world suffer from micronutrient malnutrition. This review is aimed at giving an overview of the data pertaining to the Fe, Mn, Zn, and Cu content of the grains of the globally most important cereals -wheat, rice, and maize, reported mostly during the last two decades. The prevailing opinions on their importance in the food chain, and current strategies for enrichment of cereal grains with those essential microelements are briefly summarized.
