The content of dry matter, total protein, ether extract, crude ash and crude fibre was determined in the plant material. In addition, the BAW was calculated and the content of: Mg, Ca, K, Na, Fe, Cu, Mn and Zn was assessed. The highest (P < 0.05) concentration of nutrients in dry matter was characteristic of fennel flower and green pepper.The highest abundance of minerals in crude ash was found in lovage and marjoram (144.4-116.6 g kg-1), and of total protein – in common basil and lovage (208.8 and 185.4 g kg-1). The highest (P < 0.05) content of crude fat was determined in common juniper, nutmeg, green pepper, marjoram and rosemary (on average 17.18 g kg-1) and of fibre in coriander (107.2 g kg-1), while the highest BAW was recorded in nutmeg, white pepper and rosemary (on average 730.9 g kg-1). The % RDA and AI coverage were estimated for consumers aged 31-50, assuming that the intake of the analysed culinary herbs is equivalent to 1g per day. The herbs had highly differentiated content of the analysed minerals. Common basil contained the highest amounts (P < 0.05) of macroelements: Mg, Ca, K and Na (79.8, 1278, 2135 and 218.5 μg g-1, respectively) and microelements: Fe, Cu and Mn (26.31, 1.95 and 8.56 μg g-1, respectively). Of all the herbs, fennel flower was the most abundant (P < 0.05) source of Zn (74.53 μg g-1), while juniper and green pepper was the richest in Mg (an average content 86.8 μg g-1), marjoram and lovage – in Ca (1666 and 1041 μg g-1 respectively), and red pepper – in K (2114 μg g-1). According to calculations, the consumption of 1 g of the above herbs can cover up to approx. 0.1% of RDA (Mg, Ca,) and AI (K, Na) and up to 0.6% of RDA (Fe, Cu, Mn, Zn).

Melons are highly demanding, thermophilous plants, which is why they are unpopular among fruit growers. Melon cultivation requires special treatment methods for the improvement of microclimatic conditions. Seven Polish melon cultivars are presently grown on the domestic market. They are well adapted to the local climate. The growth rate, vigor, fruit shape, fruit size, rind color and flesh thickness of those cultivars vary. The objective of this study was to determine the mineral content of edible parts of four field-grown melon cultivars in the Warmia region (NE Poland). This study discusses the mineral content of melon fruit subject to the investigated cultivar and cultivation method. In Poland, melon production is difficult and unreliable. The main problem is the selection of an appropriate cultivar and cultivation method. The analyzed material consisted of four Polish melon cultivars: Malaga F1, Melba, Oliwin, Seledyn F1, grown in a field experiment without protective cover, under polyethylene (PE) sheet cover, under non-woven polypropylene (PP) cover, with soil mulching, as well as with soil mulching under PE sheet cover or nonwoven PP cover. The highest concentrations of total N, K, Ca and Cu were determined in melon fruit of cv. Oliwin. Significant variations in total nitrogen and phosphorus levels in the edible parts of melon plants were noted subject to the applied cultivation method. Cucumis melo L. grown in the control treatment without protective cover was marked by significantly higher levels of total nitrogen and phosphorus in the fruit, compared with fruit grown with the use of other cultivation methods. The results of this study indicate that the fruit of melon plants cv. Seledyn grown in mulched soil under non-woven PP cover was characterized by the most favorable Ca:Mg and Ca:P ratios in comparison with fruit from the remaining treatments.

Melon jest rośliną mało rozpowszechnioną w uprawie. Należy do grupy warzyw ciepłolubnym o dużych wymaganiach środowiskowych, z tego względu w jego produkcji niezbędne są zabiegi poprawiające warunki mikroklimatyczne. Obecnie w uprawie znajduje się siedem odmian polskiej hodowli, dobrze przystosowanych do uprawy w naszych warunkach klimatycznych. Odmiany te charakteryzują się zróżnicowaną siłą wzrostu, kształtem owoców, ich wielkością, zabarwieniem skórki oraz warstwą miąższu. Celem badań była ocena zawartości składników mineralnych w częściach jadalnych czterech odmian melona uprawianego w warunkach polowych Warmii, w zależności od badanej odmiany oraz metody uprawy. Uprawa melona w Polsce jest trudna i zawodna. Problem stanowi dobór odpowiedniej odmiany oraz metody jej uprawy. Do badań wytypowano cztery polskie odmiany melona: Malaga F1, Melba, Oliwin, Seledyn F1, uprawianego w polu bez osłon, z zastosowaniem osłaniania roślin folią PE, włókniną PP, mulczowania gleby oraz jednoczesnego mulczowania gleby i osłaniania roślin folią PE lub włókniną PP. Spośród analizowanych odmian istotnie największą zasobnością w N-ogółem, K oraz Ca i Cu charakteryzowały się owoce odmiany Oliwin. Zastosowane w uprawie melona metody uprawy spowodowały istotne zróżnicowane zawartości azotu ogółem i fosforu w jego częściach jadalnych. Uprawa Cucumis melo L. w obiekcie kontrolnym (bez zastosowania osłon) spowodowała istotne zwiększenie zawartości azotu ogółem i fosforu w porównaniu z innymi analizowanymi metodami uprawy. Analizując stosunki Ca:Mg i Ca:P stwierdzono, że uprawiane na glebie mulczowanej i osłanianej włókniną PP owoce odmiany Seledyn charakteryzowały się korzystną proporcją Ca:Mg oraz Ca:P w odniesieniu do pozostałych obiektów uprawy.

One of the aims in coal quality studies, coal bed methane extraction studies, and research on environmental impact of coal, is a full 3D-quantitative characterisation of coal maceral content and distribution, mineral content and cleat system distribution. X-ray microfocus computer tomography, which is a non-destructive technique enabling virtual slicing opaque objects, is an excellent tool.Stacking several slices enables 3D visualisation of the object. The final images show differences in linear attenuation coefficient of X-rays. This linear attenuation coefficient depends on the density and the atomic number of the object. Consequently, components that differ in these parameters can be distinguished. A calibrated dual energy technique allows to extract quantitative information on density and atomic number of the constituents and thus enable maceral and mineral characterisation.The optimal resolution of this technique is 10 ľm in three dimensions, which is far better than for classical medical CT (500 × 500 × 1000 ľm) used in earlier studies. For this purpose, a correlation between microfocus computer tomography data with data of colour image analysis of reflected light microscopy and with back-scattered electron microscopy data allows maceral and mineral characterisation in three dimensions. Moreover, a calibration with an artificial object with several fracture apertures enables the quantification of cleat sizes.

The composition of fatty acids of serum lipids, the levels of serum lipids (total cholesterol, LDL-cholesterol, HDL-cholesterol, VLDL-cholesterol, triglycerides), mineral components (sodium, potassium, calcium, magnesium) and antioxidant vitamins (ascorbic acid, retinol, carotene, tocopherol) were determined in men aged about 25 years. The serum of hypertensive subjects (systolic blood pressure > 140 mmHg or more) contained, in relation to normotensive subjects, significantly less linolic acid, docosahexaenoic acid and oleic acid, but the total level of unsaturated fatty acids was not different between these two groups. No differences were found in the serum levels of the determined mineral components between normotensive and hypertensive men.

The aim of this study was to analyze the influence of brewing time on the content of select trace elements (Cu, Zn, Fe, Mn) and heavy metals (Pb, Cd) in homogeneous and mixed herbs used in therapy of digestive system diseases and in regulation of digestive processes. The study involved 10 types of preparations of herbal teas (mono- and multi-component sachets) acting on the gastrointestinal tract and digestive processes. Also, four types of black teas were examined for comparison. Aqueous extracts were made from each sample. As the manufacturers recommend herbal teas to be brewed for 5-15 min, in our study analyses were carried out for aqueous extracts brewed for 5 and 10 min. Contents of minerals in dry matter of the analyzed herbal and black teas and herbal blends were very differentiated, which could be due to species diversity and origin of the raw material. The brewing time had no significant effect on the percentage of the analyzed microelements extraction to the aqueous phase, however in the case of copper, manganese and lead the longer time of extraction resulted in a reduced yield of this process. An opposite dependency was noted in the case of iron, cadmium, and zinc.

Effects of salting, pickling and smoking processing methods on the mineral composition in fish products were investigated. The concentrations of Ca, P, Mg, K, Na, Cu, Fe, Zn, Mn and Se in fish products were determined during subsequent stages of processing in raw fish, semi-processed products and ready products. Fresh fish contained macro-elements in the following order: K > P > Na > Ca > Mg. The tendency was similar in semi-processed and ready products, except for the dominance of sodium. The sodium content in marinated products was three-fold higher than in fresh fish and twelve-fold higher in salted herring and cold-smoked fish. The sodium content in a 100 g portion of salted herring exceeded by six-fold the recommended daily allowance and by two-fold the tolerated amount. The content of K, Mg and P in marinated and salted herring tended to decrease throughout processing. No significant differences were observed in concentrations of Ca. The order of the concentrations of microelements was as follows: Zn > Fe > Cu > Se > Mn. The content of these elements in fish products was similar to their levels in fresh fish and corresponded to the following shares of the recommended allowances: Se up to 20%; Cu up to 11%; Zn up to 6%; Mn up to 1%; Fe up to 10%. Disadvantageous changes in the mineral composition in fish during processing result from water losses during technological processes, but the primary cause of mineral loss was leaching when the products were soaked in brine solutions with a high sodium content. Significant changes in the content of minerals in salted and pickled herring decreased the nutritional value of these products. Smaller mineral losses that occurred during smoking meant that these products were more valuable nutritionally in relation to minerals.

Food is the main source of mineral elements but some are also provided with drinking water and supplements. Juices, for example, are an important source of mineral elements. In infants’ diet minerals are provided mainly by fruit and vegetable purée juices. Infants and young children should be given juices labelled as “special purpose food”. Pasteurised juices are recommended for infants, as they are free of bacteria and toxins, a condition that cannot be completely fulfilled while making juices at home. The aim of the present work was to determine the content of some minerals in fruit and vegetable juices for infants and children under three years of age. The research material consisted of juices, all before their use-by date, purchased in grocer shops in Lublin in January 2006. In total 20 juices were examined, 8 of which were labelled as ‘special purpose food’, 2 were recommended by the National Food and Nutrition Institute and ten juices were labelled as ‘food for young children’. Juices make an important source of minerals in the diet of infants and young children. The most valuable ones are the fruit and vegetable purée juices, as they provide significant amounts of dry mass which includes fibre, minerals and vitamins. Differences in the content of particular mineral elements in juices result primarily from their composition. Although juices for infants and young children should not contain any additives, products without certificates must be treated with caution as it cannot be excluded that some may contain prohibited compounds, e.g. calcium ascorbate or calcium chloride.

Źródłem poszczególnych pierwiastków jest głównie pożywienie, niektórych dostarczają woda pitna i suplementy. Ważnym źródłem składników mineralnych w diecie dziecka są soki. Niemowlęta i małe dzieci powinny otrzymywać soki oznaczone jako „żywność specjalnego przeznaczenia żywieniowego”. Dla małych dzieci rekomendowane są soki pasteryzowane, ponieważ są one wolne od bakterii i toksyn, a tych warunków mogą nie spełniać soki wytwarzane w domu. Celem pracy było określenie zawartości wybranych składników mineralnych w sokach warzywno-owocowych przeznaczonych dla niemowląt i dzieci do lat 3. Materiał do badań stanowiły soki zakupione w sklepach spożywczych na terenie Lublina w styczniu 2006 r., w okresie ich przydatności do spożycia. Osiem zakupionych soków miało adnotację, że jest to „środek specjalnego przeznaczenia żywieniowego”, 2 były rekomendowane przez Instytut Żywności i Żywienia, natomiast 10 soków nie miało żadnych adnotacji o przeznaczeniu do żywienia niemowląt i małych dzieci. Soki są ważnym źródłem składników mineralnych w diecie niemowląt i małych dzieci. Najcenniejsze są soki przecierowe owocowo-warzywne, ponieważ dostarczają znacznych ilości suchej masy, w skład której wchodzą m.in. błonnik, składniki mineralne i witaminy. Różnice w zawartości poszczególnych składników mineralnych w sokach wynikają przede wszystkim z ich składu komponentowego. Soki dla niemowląt i małych dzieci nie powinny zawierać żadnych substancji dodatkowych, należy jednak traktować z rezerwą produkty bez atestów, nie można bowiem w nich wykluczyć obecności dodatków niedozwolonych, np. askorbianianu wapnia czy chlorku wapnia.

The experiment with ‘Boro F1’ red beet was aimed at determining the effect of the kind of nitrogen fertilizer (RSM, ENTEC 26) and the manner of application (broadcasting/liquid spreading, with / without foliar nutrition) on the content of protein nitrogen in roots, and ammonium and nitrate nitrogen content in leaves and roots of red beet. The kind of applied fertilizer did not have any influence on the size of examined parameters. In 2005 foliar nutrition with nitrogen caused a decline in nitrate concentrations in leaves and roots of the plants in comparison with unnourished objects; however, such correlation was not corroborated in the following years of the cultivation. Quantities of all examined parameters were diversified depending on the cultivation year.

Rodzaj zastosowanego nawozu nie miał wpływu na wielkość badanych parametrów. W 2005 r. dolistne dokarmianie azotem spowodowało spadek zawartości azotanów w liściach i korzeniach roślin w stosunku do obiektów niedokarmianych, ale zależność ta nie została potwierdzona w kolejnych latach uprawy. Wielkości wszystkich badanych parametrów były zróżnicowane w zależności od roku uprawy.

In recent times, pomegranate has been one of Turkey’s most important commercial fruit crops for consumption and export. In this study, the chemical composition of pomegranate (Punica granatum L.) fruits grown in the central area of Bitlis province (Eastern Turkey) was investigated. For this purpose, total phenolic content, ascorbic acid content, total anthocyanin and antioxidant activity and minerals content were evaluated. The highest total phenolic contents were determined in 13BIT1 (6477.78 mg gallic acid equivalents 100 g–1 fresh matter). The highest ascorbic acid was determined in 13BIT2 of pomegranate genotype (60.78 mg 100 g–1). Radical scavenging activity (DPPH) were determined between 13BIT18 (78.15) to 13BIT1 (31.49). Total anthocyanin of genotypes was measured between 13BIT19 (156.03) to 13BIT17 (55.37), respectively. The highest mineral compositions of the pomegranate genotypes were 998.00% N, 301.00 mg 100 g–1 P, 1708.61 mg 100 g–1 K, 55.21 mg 100 g–1 Ca, 116.79 mg 100 g–1 Mg, 5.1 mg 100 g–1 Fe, 1.91 mg 100 g–1 Cu, 0.41 mg 100 g–1 Mn and 1.20 mg 100 g–1 Zn, respectively. The results indicate that pomegranate genotypes have an important value of health and nutrition for the human.

Our study investigated the effects of dietary supplementation with zinc and polyphenol compounds, i.e. resveratrol and genistein, on the effectiveness of changes in the content of select elements (Zn, Mg, Fe, Ca, and P) in hair of rats with chemically (DMBA (7,12-dimethyl-1,2- benz[a]anthracene) induced mammary cancer. Regardless of the diet (standard; Zn; Zn+genistein) there occurred an increase in Fe and Zn content as well as a decrease in Ca, Mg, and P content in the hair of rats with mammary cancer in comparison with the content of those elements in healthy animals. Only in the group of rats supplemented with Zn and resveratrol were no changes in hair observed as compared with the control group, fed the same diet but without DMBA supplementation. The process of neoplasia in mammary tissue caused a number of changes in the concentrations of elements in hair. Certain dietary factors seem to have a significant effect on the distribution of elements in hair, but the reason for this phenomenon remains unknown.

In recent years, biofertilisers have emerged as a promising component of an integrated nutrient supply system in agriculture. The objective of this study was to examine the influence of selected biofertilisers on the vegetative growth, the content of N, P2O5 and K2O in the leaves and stems, and on the physiological parameters of pepper of the variety of ‘Sofiiska Kapiya’ cultivated under organic agriculture conditions. This experiment was carried out from 2009 to 2011 on the experimental fields of the Agroecological Centre at the Agricultural University-Plovdiv (Bulgaria), situated on the territory of a certified ecological farm. The study included the following biofertilisers – Boneprot, Lumbrical, Baikal EM “Effective Microorganisms”, Emosan, and Bio One. The results of the biometric measurements of the average plant height at the end of the vegetative period showed the highest values for the variant treated with Emosan on the Boneprot basic fertilisation (62.60 cm – 2009; 64.80 cm – 2010, and 63.87 cm – 2011). Upon feeding with the biofertilisers Emosan and Baikal EM on basic fertilisation with Boneprot (2009, 2010 and 2011) at the pepper mass fruit yield stage, plants showed higher values of net photosynthesis (PN) that were also similar to the high values observed in the flower bud stage. The highest intensity of transpiration (ȿ) was observed for the variants treated with the biofertilisers Baikal EM (2009 and 2011) and Emosan (2010) on basic fertilisation with Boneprot. It was concluded that the feeding with Emosan stimulated the vegetative growth of the pepper plants due to the high concentrations of nutrient-providing proteins contained in this biofertiliser. The results showed that biofertilisers do not significantly impact the P content of the pepper leaves and stems, but changes were more obvious in the leaves. The fertilisation with the studied biofertilisers increased the K2O content in leaves and stems compared to the control (non-fertilised) plants; the values were higher for the leaves.

W ostatnich latach bionawozy pojawiły się w rolnictwie jako obiecujący element zintegrowanego systemu dostarcznia składników odżywczych. Celem niniejszego badania było zbadanie wpływu wybranych bionawozów na rozwój wegetacyjny i zawartość N, P2O5 oraz K2O w liściach i łodygach, a także na parametry fizjologiczne papryki rocznej odmiany ‘Sofiiska Kapiya’ uprawianej w warunkach rolnictwa organicznego. Doświadczenie przeprowadzono w latach 2009–2011 na polach doświadczalnych Ośrodka Rolniczo-Ekologicznego Uniwersytetu Rolniczego Plovdiv (Bułgaria) położonych na certyfikowanej farmie ekologicznej. Badanie dotyczyło następujących bionawozów: Boneprot, Lumbrical, Baikal EM “Effective Microorganisms”, Emosan oraz Bio One. Wyniki pomiarów biometrycznych przeciętnej wysokości rośliny pod koniec okresu wegetacyjnego wykazały największe wartości dla odmiany, której aplikowano Emosan przy podstawowym nawożeniu Boneprotem (62,60 cm – 2009; 64,80 cm – 2010 oraz 63,87 cm – 2011). W przypadku podawania bionawozów Emosan i Baikal EM przy podstawowym nawożeniu Boneprotem (2009, 2010 oraz 2011) na etapie plonowania owoców papryki, rośliny wykazywały wększe wartości fotosyntezy netto (PN). Wartości te były podobne do dużych wartości zaobserwowanych na etapie pąków kwiatowych. Największą intensywność transpiracji (E) zaobserwowano u odmian, którym podawano bionawozy Baikal EM (2009 i 2011) oraz Emosan (2010) przy podstawowym nawożeniu Boneprotem. Wyciągnięto wniosek, iż zastosowanie Emosanu stymuluje wzrost wegetacyjny roślin papryki ze względu na wysokie stężenia białek dostarczającyh elementów odżywczych zawartych w tym bionawozie. Wyniki wykazały, że bionawozy nie wpływają w sposób istotny na zawartość P w liściach i łodygach papryki, ale zmiany były bardziej oczywiste w liściach. Nawożenie badanymi nawozami zwiększało zawartość K2O w liściach i łodygach w porównaniu z kontrolą (rośliny nienawożone), a wartości te były większe dla liści.

Proximate composition, profi les of amino acids, sugars, organic acids, vitamins and minerals of fourteen Turkish hazelnut varieties harvested in 2013 and 2014 were investigated. Glutamic acid, arginine and aspartic acid were the most predominant amino acids, representing of about 50% of hazelnut protein. Individual amino acid profi les showed signifi cant differences depending upon the harvest year (p<0.05). Concentration of sucrose was the highest followed by fructose, glucose, stachyose, raffi nose and myo-inositol, respectively. Phytic acid was predominant organic acid in all varieties, followed by malic acid. Independent of the variety, hazelnuts were rich in pantothenic acid, nicotinic acid, pyridoxal, biotin, thiamine, nicotinamide. Pantothenic and nicotinic acid were signifi cantly higher in most of the varieties in harvest year 2014. Potassium was the most predominant mineral, followed by magnesium, calcium, sodium, manganese, zinc, iron and copper, respectively.

The qualities of 21 honey samples from different areas of Poland were evaluated. Five common physicochemical parameters were analyzed: moisture, dye (color), pH, acidity (free, lactonic and total), electrical conductivity and trace elements (Al, B, Ba, Cd, Co, Cr, CD, Fe, Mn, Ni, Pb and Zn). The Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) was applied to determine mineral content. Chemometric methods were used to classify honey according these parameters. These methods are an effective tool to evaluate the foodstuffs quality. Honey in our study were agreeable with PN-88/A77626 and EU 2001/110/EC standards. The moisture did not exceed 20 %. The values of electrical conductivity.were from 1,213 to 2,439 10-4. S . cm-I for rape honey and from 9.315 to 13.946 10-4 . S . cm-l for honeydew honey. Generally the content of elements were up to European Standard - Cu (0.2-1.2 mg . kg-l), Zn (1.83-9.93 mg . kg-1).

Celem prezentowanych badań było scharakteryzowanie miodów na podstawie właściwości fizyczno-chemicznych (zawartości wody, barwy, pH, wolnych kwasów, laktonów, kwasowości ogólnej, przewodności elektrycznej) oraz oznaczenie zawartości pierwiastków (Zn, Fe, Cu, Cd, Pb, Al, Mn, Ni, Cr, Co, Ba i B) w próbkach miodów pochodzących z różnych regionów Polski, reprezentujących trzy różne odmiany: podkarpackie - spadziowy, świętokrzyskie - spadziowy i rzepakowy, kujawsko-pomorskie - rzepakowy, zielonogórskie - gryczany, małopolskie - rzepakowy, gryczany i spadziowy. Do oznaczenia zawartości pierwiastków zastosowano technikę spektrometrii mas z plazmą wzbudzoną indukcyjnie (ICP-MS). W celu klasyfikacji miodów na podstawie określanych parametrów zastosowano analizę chemometryczną. Metody te są efektywnym narzędziem w ocenie jakości produktów spożywczych. Badane miody spełniają wymagania jakościowe określane przez PN-88/A77626 oraz Dyrektywę UE 2001/11O/EC. Zawartość wody nie przekroczyła 20 % dla każdej z badanych próbek miodów. Przewodność elektryczna dla miodu rzepakowego wynosiła 1,213-2,43910-4. S. cm-l, zaś dla miodu spadziowego 9,315-13,94610-4. S. cm-l. Dopuszczalne zawartości większości pierwiastków w miodach spełniały dopuszczalne normy: zawartość Cu (0,2-1,2 mg . kg-I), Zn (1,83-9,93) w miodach spadziowych. Zawartość ołowiu (0,037-9,202 mg . kg-I) dla miodu spadziowego z Podkarpacia i miodu rzepakowego z regionu świętokrzyskiego przekroczyły dopuszczalne stężenie 0,4 mg . kg-I.

The present study was undertaken to determine the physico-chemical properties (moisture content, reducing sugars, proline content, electrical conductivity, ash content, pH, titrable acidity, HMF, water activity, total soluble solids and total solids), enzymatic activity (diastase and invertase), colour characteristics (mmpfund, ABS450 and CIE L*a* b') and mineral content (Cu, Mn, Fe, Zn, Pb and Cd) of three different varieties of honeys from Kashmir valley of India (acacia honey, pine honeydew and multifloral honey). Of the honey samples analysed, only pine honeydew were grouped in dark category of honey (L*<50) while acacia honey and multifloral honey were confirmed as light coloured honeys (L*>50) and possessed both red and yellow components. The concentrations of mineral content were found highest in pine honeydew followed by multi floral and least in acacia honey. All the physico-chemical properties and enzymatic activity indicated that all the three analysed varieties of honey met the criteria set by the International Honey Commission and revised codex standards for honey. The source of honey had a significant effect (p<0.05) on physico-chemical characteristics, enzymatic activity, mineral content and colour properties. Strong and positive correlations exhibited among minerals, colour (mmpfund) and L* value indicated that dark coloured honey contained high mineral content. Multivariate analysis proved to be an effective tool in classifying the three varieties of honey based on physico-chemical characteristics, enzymatic activity, mineral content and colour properties.
