Arthrospira spp. (known commercially as Spirulina) and Chlorella spp., valued for their evidence-based nutritional bioactive properties, are cultivated the purpose of production food supplements worldwide distribution. However, quality safety final product depends on culturing manufacturing conditions. The present study investigated content toxic elements (As species, Al, Cd, Hg, Ni, Pt, Pb, Cr (VI), rare earth elements) minerals (Ca, Co, Cr, Cu, Fe, K, Na, Mg, Mn, P, Zn) in (n = 10)...
There is an ongoing interest in the production of mushrooms as food, and with their consumption on rise, there a need to establish different safety measures. In present study, six mushroom species (Agrocybe cylindracea, Clitocybe maxima, Flammulina velutipes, Ganoderma lucidum, Lentinula edodes Pleurotus eryngii) were cultivated two commonly used substrates (A—based alder beech sawdust; B—based oak sawdust flax shives). The aims determine growth accumulation 70 elements fruiting bodies, 33...
The aim of the study was to evaluate possibility supplementation with inorganic forms selenium (Na2SeO4 and Na2SeO3) in concentrations 0, 0.1, 0.2, 0.4, 0.6, 0.8, 1.0 1.5 mM three medicinal mushroom species: Agrocybe aegerita, Hericium erinaceus Ganoderma lucidum. Tested species grew Se additions 0-0.6 (A. aegerita H. erinaceus), while growth G. lucidum bodies observed for 0-0.8 mM. For latter species, total content highest. Content Seorg diverse; control it highest (only organic were...
Mushrooms are known to accumulate various concentrations of different arsenic (As) species depending on the metalloid residue level in substrate. These toxicity humans and may represent a significant health problem. In present study, edible fungal (Agaricus bisporus, Pleurotus ostreatus, eryngii Hericium erinaceus) grown separately substrate containing As (As(III), As(V) dimethylarsinic acid—DMA; each form individually) at (0.1–0.8 mM) exhibited accumulation total As, lowest being A. b...
The paper presents the determination of iron forms in food products. procedure sample extraction was developed and optimized, preserving content particular iron. colorimetric method using 2,2′-bipirydyl (measurements at 520 nm) applied Fe(II) determinations, while Fe(III) with potassium thiocyanate 470 applied. total determined by technique atomic absorption spectrometry, which allowed for organic inorganic complex compounds. Detection limits 1 mg kg−1 were obtained all forms, precision...
The study investigated effect of substrate supplementation with Se alone or in combination Cu or/and Zn on (1) the growth Pleurotus ostreatus and eryngii; (2) elements accumulation mushrooms; (3) antioxidant activities bio-enriched mushroom extracts human platelets. generally increased over concentration gradient reaching its maximum at 1.2 mM for P. eryngii: 100 80 mg kg−1 Se, respectively (Se supplementation); 15 30 Cu, (Se+Cu); 85 Zn, respectively. was predominantly accumulated as an...
The phenolic and flavonoid contents composition the antioxidant ability in Hericium erinaceus , Ganoderma lucidum Agrocybe aegerita under selenium (Se) addition to growth medium were studied. of total Se fruiting bodies controls (0 mM Se) 4.58 ( A. ), 8.53 G. 14.29 H. ) mg kg –1 dry weight (DW), was significantly increased by enrichment substrate. phenolics lower (17.10, 28.11, 16.05 gallic acid equivalent (GAE)/g extract, respectively) than for Se-rich mushrooms (26.29, 40.29, 20.07 GAE/g...
A method of extraction has been proposed for the determination inorganic species As(III) and As(V) in exchangeable fraction sediments left by 2004 tsunami. The combines fractionation solid samples with speciation analysis high performance liquid chromatography hydride generation atomic absorption spectrometry (HPLC-HG-AAS). is a phosphate buffer Na2HPO4 KH2PO4, different concentrations ranging from 5 to 50 mmol L−1. This tested masses as well times extraction, pH, temperature, presence or...
The content of arsenic (As) in mushrooms can vary depending on the concentration level this metalloid soil/substrate. present study evaluated Boletus badius fruiting bodies collected from polluted and non-polluted sites relation to element overgrown substrate. It was found that arsenic-polluted contained mean concentrations 49 450 mg As kg(-1) dry matter (d.m.), with greatest for specimens growing close proximity sludge deposits (490±20 kg(-1)d.m.). total clean ranged 0.03 0.37 B. could...
The market of food supplements (FS) in European Union (EU) is on the rise. present study investigated content essential (Ca, Co, Cr, Cu, Fe, K, Mg, Mn, Na, Zn) and toxic elements (Cd, Cr(VI), Ni Pb) 168 FS produced EU designed to support various health aspects (nutrition, neurological function, reproduction, weight loss, cosmetic appearance). majority did not exceed a dissolution time 60 min hydrochloric acid (89.8%) phosphate buffer (85.7%). Cd Cr(VI) were detected any FS, Pb sporadically...
Abstract The purpose of this paper is to present a procedure for the simultaneous determination metalloids: arsenic, antimony, and selenium. Hydride generation was provided in reaction vessel connected with atomic absorption spectrometer (AAS) fast sequential mode. Two different types water samples were used while developing application: seawater groundwater. methodology liquid analysis developed detection limits 0.05, 0.03, 0.06 ng · mL−1 selenium, respectively, 10 mL samples. This...
Construction and optimisation of a hyphenated analytical system for high performance liquid chromatography with hydride generation atomic absorption spectrometry detection are described together results its use investigation food products. The anion-exchange chromatographic column permitted separation inorganic selenium species Se(IV) Se(VI) at the limit 10 ng mL−1 both species. was used determination in dietary supplements available on Polish market. content found not to exceed 50% total...
