Introduction. Antinutritional factors in legumes lower the nutritional value of foods by lowering the digestibility or bioavailability of nutrients. Technological processes applied in food production (e.g. extrusion, fermentation, germination) may influence the leguminous seeds matrix composition which in consequence may affect (improve or decrease) mineral bioaccessibility and uptake in animals and humans. The aim of this study was to determine the effect of fermentation and extrusion processing, as well as their combination, on the potential availability of Fe, Cu, and Zn from lupine grain preparations. Materials and methods. The content and the release of Fe, Cu and Zn from three different lupine species (Lupinus albus, Lupinus luteus, Lupinus angustifolius) was determined. The samples were subjected to enzymatic digestion under in vitro conditions. The content of minerals in lupine grains before and after enzymatic digestion was determined by the flame atomic absorption spectrometry. Results. The degree of release of Fe, Cu, and Zn from dehulled lupine grains was higher than from whole grains. Fermentation processing increased the degree of Fe release, extrusion decreased the degree of Cu release, while the extrusion after fermentation processing increased the degree of Fe release from lupine grain preparations. Conclusions. The degree of mineral release from lupine grains depends on the hull con-tent, technological processing applied and the lupine variety

The experiment described in the paper focused on the effects of complementary and excess diet supplementation on body weight changes and fat tissue accumulation. Untreated wheat, corn grains, and barley grits in the original diet were isocalorically substituted with wheat flour, sucrose, and minerals (calcium, magnesium, chromium, and zinc). The feed in which whole cereal grains were replaced by flour and sucrose did not significantly affect the amount of feed consumed, body weight gains nor fat accumulation. Diet supplementation with selected mineral components to compensate for the deficiencies caused by the modification produced, in the female rats, significantly reduced body weight gains (0.3± 1.9 g/100 g diet) and perivisceral fat accumulation (pericardial fat 0.009±0.005 g/100 g diet; peri- intestinal 0.790±0.575 g/100 g diet), whereas significantly increased muscle fat content (6.49±0.15 g). At comparable body weight gains, the male rats showed a significantly higher perivisceral (pericardial fat 0.039±0.008 g/100 g diet; peri-intestinal 0.769±0.152 g/100 g diet) and intramuscular fat accumulation (6.49 ±0.15 g). Excess supplementation resulted, in both sexes, in a significantly reduced feed consumption accompanied, however, by significantly higher body weight gains per unit feed consumed (females 4.8±2.3g/100g diet; males 3.7±3.1 g/100 g diet) as well as by a significantly higher accumulation of perivisceral and intramuscular fat (females 0.058±0.024 g/100 g diet; 2.060±0.676 g/100 g diet; 7.53±0.12 g; males 0.42±0.16 g/100 g diet; 0.934±0.305 g/100 g diet; 5.48±0.16 g, respectively). The modified diet and its supplementation resulted in significant changes in the contents of individual fatty acids in the perivisceral fat, the changes involving mainly an increase in saturated and monounsaturated acids and a reduction in polyunsaturated acids, particularly in the males.

The research objective was to determine and compare dry matter, crude protein, mineral elements (total), dietary fiber, easily hydrolysable sugars, vitamin C, and minerals (K, Na, Mg, Cu) as well as the content of epicatechin and phenolic acids (homovanillic, chlorogenic, caffeic, coumaric, and ferulic) in the flesh and peel of ‘Šampion’ cv. apples grafted on 4 different rootstocks types: M.26, P2, M.9, and P22 in 2014–2015. The apples from trees grafted on the P22 rootstock had the highest content of dry matter, crude protein, fiber, easily hydrolysable sugars, and vitamin C. The highest mineral compound concentration was exhibited by apples from trees growing on rootstocks P22, P2, and M.9. The highest concentration of phenolic acids was determined in the peel of fruits from trees growing on P22 and M.9. The observations confirm that rootstocks characterized by the lowest growth rate (P22, M.9) ensure the highest accumulation of nutrients in ‘Šampion’ fruits.
