“…In 64% aqueous ethanol extract of defatted powdered wheat grain we found FFA as a basic component. Hung et al (2011) evaluated the proportion of ferulic acid from the total detected phenolic compounds as 71.0-72.3%. Thus, the phenolic acids profile and the concentration of individual phenolic acids are dependent on the wheat varieties and growing location.…”

Einkorn (Triticum monococcum L., subsp. monococcum), emmer (Triticum dicoccum Schuebl [Schrank], subsp. dicoccum) and spring wheat (Triticum aestivum L.) may be rich in hydrophilic antioxidants, therefore being a potential food source with high nutritional properties. The aim of the present study was to assess the content of free ferulic acid (FFA) and total polyphenols (TP) beneficial for human health in wheat varieties and accessions for breeding and production. Einkorn, emmer and spring wheat varieties were assessed for TP and FFA contents in the precise two-year field experiments. The highest FFA content was determined in emmer wheat varieties and spring cv. Granny. High TP content was characteristic for emmer and spring wheat accessions, however also some einkorn ones were characterised by high levels. Year of cultivation showed a significant impact on FFA contents.

“…They observed higher antioxidant activity only after the application of 300 kg N ha -1 . Hung et al (2011), as well as Okarter et al (2010) analyzed the antioxidant activity of sprouted wheat grains and their phenolic content, and positive correlations between these parameters were found when whole wheat grains were investigated. The results of the present study also confirmed this, since the ACI calculated for each fertilization treatment in most cases coincides with the total phenolic content.…”

“…Wheat is one of the most popular sources of food and should have a high nutritional value. Wheat grown under appropriate conditions contains many macro-and micronutrients as well as phenolic acid compounds with well documented antioxidant activity (Okarter et al 2010, Hung et al 2011. In response to changing environmental conditions and their adaptation to existing conditions, plants modify their metabolism and uptake of elements, including heavy metals and other contaminants.…”

Non-standard materials used for plant fertilization, require characterization to reduce any possible undesired effects. The aim of this study was to investigate the effect of fertilization with biogas digestate (BD) and mining waste (carboniferous mudstones (MS) from coal mine) on wheat yield quality and the bioaccumulation of heavy metals in wheat grains in relation to conventional fertilization (NPK) and no fertilization. Using the co-application of waste (MS+BD), the highest yield was obtained in the first and second year, but in the third year, a slight decrease in yield was observed compared to NPK. In all years, BD and MS+BD fertilization increased the content of protein, wet gluten, and phenols in wheat grain compared to NPK and no fertilization. Waste fertilization had a positive effect on the antioxidant capacity index of grain but only in the first year. The bioaccumulation index (BAI) demonstrated that NPK decreased BAI for Zn, B, Cd, and Mn, whereas MS+BD decreased BAI for Cu, Sr, Pb, Co, Ba, and Cr.

“…Similar observations were made by Mazzoncini et al (2015), who found that syringic acid was dominant in winter wheat and its content was significantly increased by organic fertilization (compared to conventional cultivation). Also, Hung et al (2011) found syringic acid to be the main compound in the free phenolic alcoholic extracts of the wheat meal representing 77.0% of the total amount of detected free phenolic compounds. These differences come from the evidence that only free phenolics were studied and it is a well-known fact that in cereals most phenolics are found in bound form.…”

“…The antioxidant capacity of wheat grains usually correlates with the content of total phenolics (Okarter et al 2010, Hung et al 2011). According to the literature, accessibility of nitrogen to plants is important due to effects on the antioxidant potential.…”

The food industry faces the problem of soil contamination and consequently the deterioration of the quality of plant products. Here, we present a study on evaluation of the effect of fertilization with sewage sludge (SL) with varying, rates of biochar (BC 2.5, 5 and 10% of DW) on yield quality and the accumulation of heavy metals in wheat grains. The greatest grain yield with the highest content of protein and gluten as well as the highest total content of phenols and flavonoids, was obtained when SL+5%BC fertilization was applied. The addition of 5%BC and 10%BC to SL resulted in the greatest increase in the antioxidant capacity of grain. Among phenolic acids, syringic acid was found in the largest amount in grain in the SL+2.5%BC treatment. A significant decrease in Pb accumulation in wheat grain after application of SL+5%BC and a successive decrease in Al content with increasing BC addition were observed. To increase the quality of wheat grains and to reduce the bioaccumulation of harmful elements after the application of biochar to the soil is important in the context of food safety and health of humans especially in food production on acidic and/or contaminated soils.
