Opis:: The test material originated from a field experiment conducted in 2010-2013, at the Experimental Farm in Felin (51°22’ N, 22°64’ E), which belongs to the University if Life Sciences in Lublin. A two-factor experiment was conducted in randomised blocks with 4 replicates. The chemical composition of grain of 4 wheat species was analysed: common wheat (Triticum aestivum ssp. aestivum L.) cv. Tonacja, durum wheat (Triticum durum Desf.) cv. Komnata, spelt (Triticum aestivum ssp. spelta (L.) Thell.) cv. Schwabenkorn, and einkorn wheat (Triticum monococcum L.) line PL 5003 (material acquired from the National Centre of the Plant Gene Pool), grown at different production technology intensity (medium and high level of cultivation technology). The analyses on wheat grain included the content of total protein, crude ash, crude fat, crude fibre, carbohydrates, phosphorus, potassium, magnesium, calcium, copper, iron, manganese and zinc. The results were subjected to an analysis of variance, while the differences were estimated by the Tukey’s test at the significance level of p = 0.05. In order to identify the correlations and relationships between selected grain quality traits, an analysis of multiple correlation was employed and coefficients of variation were calculated (CV, %). Einkorn wheat proved to have the highest levels of protein, fat, ash, phosphorus, potassium, magnesium, calcium, copper, zinc, iron and manganese. Among the remaining genotypes, common wheat had the highest levels of carbohydrates and fibre. Irrespective of the genotype, more intensive chemical weed and pest control and nitrogen fertilisation had a favourable effect on the content of protein and fat, while reducing the levels of fibre and carbohydrates. Most of the macroelements, except phosphorus, and all the microelements reached higher concentrations under the more intensive production technology. In terms of grain quality, the response of the genotypes to the intensification of production technology was only slightly varied.

Opis:: Fish are most often considered as a rich source of valuable fat, although sometimes the high quality of fish meat protein is also emphasized, but there is comparably little information on the mineral composition of fish meat. Chemical composition, caloric value and health safety of fish as food depend on many factors, of which the rearing conditions are most influential. Aside from environmental conditions, production technology is a major determinant of the quality and nutritional value of trout. In this study, the influence of a farming technology on the content of minerals in the muscle tissue of rainbow trout (Oncorhynchus mykiss Walbaum) netted in various Polish regions has been assessed. Fish were caught in autumn 2010 and 2011 and spring 2011, at 3 farms with a water flow-through system and 3 farms with water recirculation. The trout muscle tissue contained: 188.4 - 518.4 mg kg-1 of calcium, 306.9 - 338.1 mg kg-1 of magnesium, 464.0 - 718.2 mg kg-1 of sodium, 4.5 - 6.9 mg kg-1 of zinc, 2485.7 - 2823.6 mg kg-1 of phosphorous, 4261.2 - 4615.4 mg kg-1 of potassium, 3.0 - 9.4 mg kg-1 of iron and 0.09 – 11.74 mg kg-1 of copper. The farming technology influenced the content of calcium, sodium, zinc, iron and copper but had no effect on the content of magnesium, phosphorous and potassium in rainbow trout muscle tissue. Trout farmed in water recirculation systems contained higher amounts of most elements than the fish reared in water flow-through systems. The season of sample collection (date of netting) also affected the content of sodium, zinc, phosphorus, iron and copper. The fish farming site (localization of the farm) determined the content of most of the minerals except magnesium. Rainbow trout is a good source of phosphorous and potassium in a human diet, significantly covering the daily demand for the elements.
