The level of biogenic elements and heavy metals in the almond kernel in the ecological conditions of Dalmatia (Croatia) - organic farming

Abstract

Jezgra bajama, kao i drugi orašasti plodovi sadrži znatne razine biogenih elemenata neophodnih za ljudsko zdravlje. U ekološkim uvjetima Ravnih kotara provedena su istraživanja razina devet biogenih elemenata (N, P, K, Ca, Mg, Mn, Zn, Cu i Fe) i tri teška metala (As, Cd i Pb). Temeljem rezultata istraživanja, razine biogenih elemenata su u suglasju s istraživanjima u glavnim proizvodnim područjima u svijetu, osim za P i Fe, kojih su razine u našem proizvodnom području značajno više. Glede teških metala, razine Cd i Pb s u ispod točke detekcije, a As niža no u ostalim proizvodnim područjima. Kod razina određenih biogenih elemenata i teških metala dolazi do izražaja genetska specifičnost usvajanja istih. Dobiveni rezultati nam potvrđuju da se jezgra bajama iz proizvodnog područja Ravnih kotara odlikuje visokim sadržajem biogenih elemenata i zanemarivom razinom teških metala. Istraživanja dodatno pridonosi boljoj valorizaciji jezgre bajama proizvedenih u ekološkim uvjetima Ravnih kotara, cjenovnoj stimulaciji za proizvođače i zdravstvenoj dobrobiti za konzumente.The almond kernel, like other nuts, contains significant levels of biogenic elements necessary for human health. In the ecological conditions of Ravni kotari, research was carried out on the levels of nine biogenic elements (N, P, K, Ca, Mg, Mn, Zn, Cu and Fe) and three heavy metals (As, Cd and Pb). Based on the research results, the levels of biogenic elements are in agreement with research in the main production areas in the world, except for P and Fe, the levels of which are significantly higher in our production area. Regarding heavy metals, the levels of Cd and Pb are below the detection point, and As is lower than in other production areas. At the levels of certain biogenic elements and heavy metals, the genetic specificity of their adoption comes to the fore. The obtained results confirm that the kernel of almond from the production area of Ravni kotari is characterized by a high content of biogenic elements and a negligible level of heavy metals. Research additionally contributes to the better valorization of the almond kernel produced in the ecological conditions of Ravni kotari, price stimulation for producers and health benefits for consumers
