Types Of Grains Research Articles

ОБМІН ЯК ФОРМА ЗБУТУ ГЛИНЯНИХ ВИРОБІВ ГОНЧАРІВ ЛІВОБЕРЕЖНОЇ УКРАЇНИ В ДРУГІЙ ПОЛОВИНІ ХІХ – НА ПОЧАТКУ ХХ СТОЛІТТЯ

The proposed article summarizes scattered material on exchange as one of the forms of selling clay products, used by potters of the Left Bank of Ukraine in the second half of the 19th – and early 20th centuries. Territorially, the study covers the Kharkiv, Chernihiv and Poltava provinces, where the exchange has become the most widespread. The written sources of the outlined period and contemporary ceramologists were studied to identify the necessary information. The analysis of the literature made it possible to draw a conclusion about the dispersion and certain fragmentation of the materials on the researched problem, which determined the purpose of the proposed research. It was found that the dishes were most often exchanged for grain, eggs, vegetables, other foodstuffs, and flax and yarn. The exchange equivalence was influenced by the type of grain for which products were exchanged. It has been proved that the exchange became more widespread in the territories where the land was unproductive or unsuitable for agricultural cultivation, where the potters had little land. It was found out that watered and terracotta products had different terms of exchange. On the basis of the studied sources, it was established that the profitability had a special influence on the exchange equivalence: the lower it was, the less valued earthenware was. The author traced that the exchange became more active after the end of the harvest and before major religious holidays, when the obligatory custom dictated the use of new dishes. It was found out that not only manufacturers resort to exchange as a form of sale, but also intermediaries – buyers. Earthenware was exchanged not only during the delivery of goods in the surrounding territories, but also at fairs and bazaars, in particular at the sub-market. On the basis of studied sources, it was established that potters and buyers actively used the exchange of pottery products in parallel with their sale for cash until the 1880s, and by the beginning of the 20th century, it had almost fallen out of use as a form of sales.

Dynamics of moisture content and sowing qualities of seeds in rice varieties during post-harvest ripening and storage

Rice seeds at each stage of ripening are characterized by a certain state, structure and moisture. Such properties of rice as germination, nature, quality and duration of storage depend on moisture content. Biochemical processes in the grain do not end at the filling stage, but continue for some post-harvest period. To safely preserve the rice gene pool, it is necessary to clarify the effect of seed maturity and storage time on seed quality. The varietal characteristics of rice seeds were studied using 8 Kuban varieties harvested on days 35 and 45 after flowering. The structural-phase state of freshly harvested grain and after 5, 10 days of ripening in natural conditions at room temperatures, and then the dynamics of sowing qualities after 1, 6 and 10 months of storage are discussed. The following parameters were studied: moisture, germination, length of the seedling and seed root, mass of 1000 grains. Differences in the moisture yield of grain of different degrees of maturity, varieties with different types of grain are shown. The results of the evaluation of rice physico-chemical indicators at the end of post-harvest ripening are presented. Varieties with slow moisture yield during ripening were distinguished by increased grain size: Yakhont, Rubin, Thaibonne and Zlata. The germination of seeds increased as they ripened, compared with freshly harvested ones, after a month it increased by almost 50%, and reached its maximum value by 6 months of storage, after 10 months, on average, germination for the group of varieties has already decreased by 6%. The stage of seed harvesting significantly influenced the germination rates.

Nutritional assessment of nixtamalized maize tortillas produced from dry masa flour, landraces, and high yield hybrids and varieties.

In the scientific literature there are different analyses of the nutritional profiles of maize tortillas, whether they are landraces or hybrid maize versus those made with dry masa flour (DMF). In general terms, there is agreement in the reported content of moisture. However, for the other nutrients, a great disparity is reported for each type of tortilla which may be due to various factors such as the type of maize or processing methods. In this study, the nutritional aspects of maize tortillas made with different genotypes (five hybrids, two varieties, five landraces, six hybrid mixtures and six dry masa flours) under controlled conditions, were compared. More than 30 characteristics were analyzed. High performance hybrids and varieties (HPHV) and landraces had the highest (p < 0.05) antioxidant capacity (58.8% free, 150.2% bound). In terms of vitamins contents, the tortillas produced from DMF contained 11.2 and 3.5 times more B1, 18.6 and 7.8 times more B2, and 2.7 and 5.3 times more B3 than HPHV and landraces respectively; and only in these samples was detected folic acid. DMF tortilla samples contained 1.75 times more sodium and 2.75 times more iron than the other groups, and 0.75 times less calcium than HPHV. Zinc was present in higher concentration (p < 0.05) in DMF tortilla samples. The landraces had the highest protein content (average 10.28%), but the tortillas produced from DMF presented the highest protein quality evaluated by protein digestibility-corrected amino acid score (PDCAAS) (p < 0.05) that represents 27, 25 and 19% more than hybrids mixture, HPHV and landraces, respectively. This work gives valuable information on how different types of grains differ in the nutritional quality affecting the final product to provide more elements in the decision-making of processors. There is no a perfect maize, but there are genotypes that can be combined as mixtures and the processing method to design superior nutritional tortillas and related products for populations that highly consume them and improve their human health.

Effect of Thermal Treatment on the Structure and Morphology of Vanadium Doped ZnO Nanostructures Obtained by Microwave Assisted Sol-Gel Method.

In this paper, we conducted a fundamental study concerning the effect of thermal treatment on the structure and morphology of 2 mol% vanadium doped ZnO nanopowders obtained by microwave assisted sol-gel method (MW). The samples were analyzed by DTA, FTIR, XRD, SEM, and UV-Vis spectroscopy. The DTA results showed that above 500 °C, there was no mass loss in the TG curves, and ZnO crystallization occurred. The XRD patterns of the thermally treated powders at 500 °C and 650 °C showed the crystallization of ZnO (zincite) belonging to the wurtzite-type structure. It was found that in the 650 °C thermally treated powder, aside from ZnO, traces of Zn3(VO4)2 existed. FTIR spectra of the annealed samples confirmed the formation of the ZnO crystalline phase and V-O bands. The micrographs revealed that the temperature influenced the morphology. The increase in the annealing temperature led to the grain growth. The SEM images of the MW powder thermally treated at 650 °C showed two types of grains: hexagonal grains and cylindrical nanorods. UV-Vis spectra showed that the absorption band also increased with the increasing temperature of thermal treatment. The MW sample annealed at 650 °C had the highest absorption in ultraviolet domain.

Knowledge regarding the ill effects of Grain Dust Exposure on Respiratory System and its Prevention among Flour Mill workers in Bangalore Rural

Grain dust is the dust produced during harvesting, drying, handling, storage or processing of wheat, oats, rice, barley or maize. Grain dust is composed of a large number of materials including various types of grain and their disintegration products, silica, fungi, insects and mites. The study aims to assess the knowledge and determine the relationship regarding the ill effects of grain dust exposure on respiratory system among flour mill workers. The research approach for this study is explorative and descriptive survey. The researcher planned to explore the knowledge regarding the ill effects of grain dust exposure on respiratory system and its prevention. The structured interview schedules were tried out with flour mill workers in selected flour mill at Bangalore rural. Split half method was done and co- efficient correlation was found (r= 0.82) which indicates high degree of reliability. Finding of the study showed, knowledge score of the flour mill workers 82% of them were having below average knowledge and 10% of them were having average knowledge and 8% of them only having good knowledge regarding the ill effects of grain dust exposure. The study concluded that the knowledge of mill workers is a basic education programme in community area such as occupational health. The primary task of nursing education is to improve the knowledge and practices to prevent the ill effects among occupational development among the community.

Multivariate analysis of Lower Cretaceous monosulcate pollen from central-western Argentina

Monosulcate pollen grains are an important component of the Mesozoic palynofloras around the world. These type of grains are produced by several groups of plants and because of the morphological similarities among them, their taxonomic determination is difficult. Currently, there is scarce information about morphological differences of monosulcate pollen grains and this makes their botanical affinity in fossil specimens challenging. In this work, we analyzed statistically the morphological features of monosulcate fossil pollen grains recovered from six palynological assemblages from the Lower Cretaceous Lagarcito Formation of central-western Argentina. We used our own fossil dataset and data from the description of monosulcate pollen grains published from Cretaceous cycadalean in situ male cones from Patagonia. Furthermore, morphological variables from selected living species were added to support the analysis. According to our results, two main groups with clear morphological features were characterized among fossils. The use of an extant dataset allowed us to support the exine sculpture as an important variable when characterizing fossil pollen grains. Finally, our fossil dataset showed similarities with the in-situ pollen grains from the cycadalean cone species Androstrobus munku and Androstrobus patagonicus. This work is the first attempt to identify different morphological types among fossil monosulcate pollen grains recovered from the Lagarcito Formation of central-western Argentina. Our results will contribute to elucidate morphological variations in fossil pollen grains and may improve future taxonomic studies.

The metagenomic composition of water kefir microbiota

Water kefir is a sourish, slightly alcoholic, and carbonated drink in which different dried fruits are added to the sucrose-containing solution and fermented using water kefir grains. Kefir grains in polysaccharide structure include Lactic Acid Bacteria (LAB), yeasts, and/or acetic acid bacteria that use sucrose as an energy source. Water kefir grains contain a varying number of microbiota with various microbiological compositions, depending on their origin. The present study metagenomically determined the microbial flora of water kefir grains obtained from five different commercial sources. According to the metagenomic composition results obtained with the selected specific primers, the dominant bacterial species in water kefir grains were determined to be Lactobacillus ruminis and Bacillus methanolicus, and the most common species were Lactococcus lactis and Enterococcus faecium. Achromobacterx ylosoxidans were detected in only one sample. Pichia kudriavzevii was the dominant yeast species, and Saccharomyces cerevisiae, Eremothecium cymbalariae, Candida glabrata, and Ogataea parapolymorph were seen as common yeast species in all kefir yeasts. Other yeast types showed differences. It was revealed that natural water kefir grains contained probiotic bacteria including Lactobacillus ruminis, so kefir produced using these types of grains can exert functional properties. Another important conclusion is that, albeit, at low levels, kefir grains contain strains that have probiotic potential, including Lactococcus lactis, Enterococcus faecium, and Lactobacillus reuteri.

Modeling of Abnormal Grain Growth That Considers Anisotropic Grain Boundary Energies by Cellular Automaton Model

A new cellular automaton (CA) model of abnormal grain growth (AGG) that considers anisotropic grain boundary energies was developed in this paper. The anisotropic grain boundary energy was expressed based on two types of grains, which correspond to two components of different crystallographic orientation in textured materials. The CA model was established by assigning different grain boundary energies and grain-growth-driven mechanisms to four types of grain boundaries formed by two types of grains. The grain boundaries formed by different kinds of grains adopted the lowest energy principle, while the grain boundaries formed by the same kind of grains adopted the curvature-driven mechanism. The morphology calculated by the CA model shows the characteristics of AGG. Then, the Johnson–Mehl–Avrami (JMA) model was fitted to predict the growth kinetics. By analyzing the fitting results, the JMA model is capable of predicting the growth kinetics of AGG. The Avrami exponent p decreases from about 1.5 to 1 with the initial number of Type II grains increasing. The investigation of the Hillert model and grain size distribution further indicates that the microstructure evolution is consistent with AGG. Therefore, the analysis of morphology and kinetics indicates that AGG can be fairly well-simulated by the present CA model.

Developing colloidal structure of beer by grain organic compounds

The present article introduces the problem of determining the general structure of beer as a complex system of related biomolecules. The objective was to establish the correlation of various quantities of organic compounds in beer formulation.&#x0D; The research featured samples of filtered pasteurized beer obtained from a retail chain shop in Moscow (Russia). The experiment relied on standard research methods, including instrumental methods of analysis, e.g., high-performance liquid chromatography (HPLC). The obtained experimental data underwent a statistical analysis using the Statistica software (StatSoft, 2016). &#x0D; The research established the correlation between the type of grain (barley or wheat malt) and the content of organic compounds, e.g., β-glucan, polyphenols, soluble nitrogen, etc. The research also revealed some patterns in the distribution of proteins, which served as a framework for the system of organic compounds. The distribution of thiol proteins proved to depend on the dissolution degree of the grain and was different in barley light, barley dark, and wheat malt samples. The fraction distribution of β-glucan depended on the color of the malt. In light beer samples, it concentrated in high- and medium-molecular fractions of nitrogenous substances, in dark beer – in low-molecular fractions (≤ 63%). Initial wort density and alcohol content affected the amount of catechins and total polyphenols. Nitrogenous compounds depended on the color, initial extract, and alcohol content. &#x0D; The nitrogenous structure and other organic compounds of beer proved to depend on protein substances. The research also revealed a number of factors that affected the fraction distribution of biomolecules in different beer sorts.

PSIII-A-10 Effect of Grain Type and wet-Aging Time on Lamb Meat

Abstract Visual appearance is critical for the consumer perception of meat quality. Color, as well as juiciness are key factors in determining consumer choice. The objective of this study was to evaluate the effect of grain type and different wet-aging periods on lamb meat. Eighteen castrated Merino x Corriedale lambs (± 40 kg) were randomly assigned to three dietary treatments: 60% corn grain (CG), 60% oats grain (OG) or all fescue hay (Control); diets were isonitrogenous (13% CP). After slaughter, pieces of Longissimus thoracis muscle from each animal were aged during 1, 4, 8 and 16 d. Treatments were arranged as a 3x4 factorial experiment, and color and water-holding variables were measured. No interactions were found (p &amp;gt; 0.05) between type of grain and aging time. Meat from CG showed the highest values for lightness, redness and yellowness (p= 0.0240, 0.0119, 0.0077, respectively), while meat from OG had the lowest values for redness and yellowness. Expressible juice was lowest (p= 0.0307) for Control, intermediate for CG and higher for OG. Meat cooking loss (p= 0.0157) resulted highest for Control, intermediate for OG and lowest for CG. Cooking loss, drip loss (48h) and expressible juice showed differences among aging periods (p= 0.002, 0.0001, 0.0015, respectively); the highest loss was found for 1d-aging, but no differences were detected for the other aging periods. The effect of aging period was greater than type of grain for cooking loss (F: 7.82, 4.48) and expressible juice (F: 5.88, 3.71) respectively. Purge-thaw loss showed no differences for diet type (p &amp;gt; 0.16) or aging period (p &amp;gt; 0.11). A more intense color developed by CG than OG might favor consumer perception of meat quality. Additionally, water-loss seems to be independent of these diets, showing that a longer aging period would be more relevant to get juicier lamb meat.

Research on a rapid identification method for counting universal grain crops.

Thousand-grain weight is a key indicator of crop yield and an important parameter for evaluating cultivation measures. Existing methods based on image analysis are convenient but lack a counting algorithm that is suitable for multiple types of grains. This research develops an application program based on an Android device to quickly calculate the number of grains. We explore the short axis measurement method of the grains with morphological thought, and determine the relationship between the general corrosion threshold and the short axis. To solve the problem of calculating the number of grains in the connected area, the study proposes a corrosion algorithm based on the short axis and an improved corner point method. After testing a variety of crop grains and equipment, it was found that the method has high universality, supports grain counting with white paper as the background, and has high accuracy and calculation efficiency. The average accuracy rate is 97.9%, and the average time is less than 0.7 seconds. In addition, the difference between the average accuracy for various mobile phones and multiple crops is small. This research proposes a grain counting algorithm with a wide range of applications to meet the requirements of nonglare use in the field. The algorithm provides a fast, accurate, low-cost tool for counting grains of wheat, corn, mung bean, soybean, peanut, rapeseed, etc., which is less constrained by space and power conditions. The algorithm is highly adaptable and can provide a reference for the study of grain counting.

Grain size analysis and characterization by Raman spectroscopy of a homogeneous sintered MOX fuel

The grain size distribution of an U0.89Pu0.11O2 MOX fuel, sintered from a freeze-granulated powder to 97% of the theoretical density at 1700 °C during 4 h, for an oxygen potential set to − 387 kJ/mol, was investigated. The sintered microstructure is constituted by 8.5 vol% of clusters of small grains, having an average grain size around 1.5 µm, dispersed in a polycristalline matrix made of larger grains having an average grain size around 7–8 µm. Characterizations by Raman micro-spectroscopy showed that the Pu/(U+Pu) content was not the same depending on the type of grain. The large grains constituting the sintered polycrystalline matrix have a Pu/(U+Pu) content in the range 9.0–11.0 mol%, which is close to the overall target. The small grains agglutinated in the form of clusters are however clearly depleted in Pu.

Invited review: Effect of subacute ruminal acidosis on gut health of dairy cows.

Subacute ruminal acidosis (SARA) is assumed to be a common disease in high-yielding dairy cows. Despite this, the epidemiological evidence is limited by the lack of survey data. The prevalence of SARA has mainly been determined by measuring the pH of ruminal fluid collected using rumenocentesis. This may not be sufficiently accurate, because the symptoms of SARA are not solely due to ruminal pH depression, and ruminal pH varies among sites in the rumen, throughout a 24-h period, and among days. The impact of SARA has mainly been studied by conducting SARA challenges in cows, sheep, and goats based on a combination of feed restriction and high-grain feeding. The methodologies of these challenges vary considerably among studies. Variations include differences in the duration and amount of grain feeding, type of grain, amount and duration of feed restriction, number of experimental cows, and sensitivity of cows to SARA challenges. Grain-based SARA challenges affect gut health. These effects include depressing the pH in, and increasing the toxin content of, digesta. They also include altering the taxonomic composition of microbiota, reducing the functionality of the epithelia throughout the gastrointestinal tract (GIT), and a moderate inflammatory response. The effects on the epithelia include a reduction in its barrier function. Effects on microbiota include reductions in their richness and diversity, which may reduce their functionality and reflect dysbiosis. Changes in the taxonomic composition of gut microbiota throughout the GIT are evident at the phylum level, but less evident and more variable at the genus level. Effects at the phylum level include an increase in the Firmicutes to Bacteroidetes ratio. More studies on the effects of a SARA challenge on the functionality of gut microbiota are needed. The inflammatory response resulting from grain-based SARA challenges is innate and moderate and mainly consists of an acute phase response. This response is likely a combination of systemic inflammation and inflammation of the epithelia of the GIT. The systemic inflammation is assumed to be caused by translocation of immunogenic compounds, including bacterial endotoxins and bioamines, through the epithelia into the interior circulation. This translocation is increased by the increase in concentrations of toxins in digesta and a reduction of the barrier function of epithelia. Severe SARA can cause rumenitis, but moderate SARA may activate an immune response in the epithelia of the GIT. Cows grazing highly fermentable pastures with high sugar contents can also have a low ruminal pH indicative of SARA. This is not accompanied by an inflammatory response but may affect milk production and gut microbiota. Grain-based SARA affects several aspects of gut health, but SARA resulting from grazing high-digestible pastures and insufficient coarse fiber less so. We need to determine which method for inducing SARA is the most representative of on-farm conditions.

Effect of Micro-Textures on the Surface Interaction of WC+Co Alloy Composite Coatings

The surface properties of alloys can be improved by coating their surfaces and adding a micro-texture. The effect on the surface properties of alloy composite coatings of adding a textured surface has not been addressed in previous studies. In this study, a micro-texture was added to the surface of a WC+Co alloy AlCrN/AlTiSiN composite coating. The influence of the micro-texture’s geometric parameters on the surface properties of the composite coating and its lifespan were studied in detail. First, the surface hardness and phases of various micro-textured composite coatings were analyzed to explore the effect of different micro-texture parameters on the surface properties. Then, a friction and wear test was conducted to establish a model that can predict the lifespan of a micro-texture and the influence of different micro-texture parameters on the surface friction of the composite coating. After that, the wear pattern of the composite coating and the relative action of the micro-texture were analyzed on the basis of the visible wear morphology. The results show that using a laser to add a micro-texture to the surface of a composite coating creates a hardened layer that increases the coating’s surface hardness. Analysis of the surface phases of the composite coating showed that there are three principal types of grain on the surface, namely WC, CrN and TiN, with WC having the largest grain size. The main kind of wear on the surface of the composite coating was found to be abrasive wear, which can be reduced by the addition of a micro-texture.

Quality Testing of Food Grains Using Image Processing and Neural Network

Abstract: The main crop for our nation to boost agricultural income is grains. While the crop is still in the ground, farmers notice yield the most, but once the grain has been processed and sold, quality becomes the main factor in determining its viability. Several contaminants, including stones, weed seeds, chaff, damaged seeds, etc., are present in these grains. Low automation levels and a large human workforce are required for assessing grain quality. Additionally, it increases the cost and length of the testing process. This contradiction is becoming more and more obvious as import and export trade expands. Prior to performing the next process during grain handling procedures, several types of grain and their quality are necessary.

Pore-Scale Modeling of Immiscible Displacement In Porous Media: The Effects of Dual Wettability

Summary Many naturally occurring porous media contain different types of grains with different wettabilities, therefore, understanding the effect of wettability heterogeneity on multiphase flow in porous media is important. We investigate the immiscible displacement during imbibition in a dual-wettability porous medium by direct pore-scale modeling. We propose a heterogeneous index (HI) to quantify the wettability heterogeneity. Our simulations on the capillary rise in dual-wettability tubes are compared with theoretical predictions, which verifies the numerical method. Our simulation results on the displacement in the dual-wettability porous media show that the wettability heterogeneity has a great impact on the fluid distribution, the capillary pressure curve, and the relative permeability curve. With the increase of wettability heterogeneity (HI), more capillary fingers are found during the displacement, the recovery rate of nonwetting fluid decreases, and the capillary pressure and the relative permeability of the wetting fluid decrease.

In-House Validation of an Efficient and Rapid Procedure for the Simultaneous Determination and Monitoring of 23 Mycotoxins in Grains in Korea

A high-performance liquid chromatography tandem mass spectrometry method is described for the simultaneous determination of mycotoxins, including Ergot alkaloids (EAs), in 3 types of grains. The extraction of 23 mycotoxins was evaluated and performed by using a modified QuEChERS-based sample preparation procedure. The proposed method was fully validated on spiked grain samples (barley, wheat and oat) to assess the linearity, limit of detection (LOD) and limit of quantitation (LOQ), matrix effects, precision and recovery. After validation, this method was applied to 143 samples of various types of 3 grains from the Republic of Korea to survey the level of mycotoxin contamination in Republic of Korean grains. A total of 42 grain samples (29%) were contaminated with at least one of these mycotoxins at levels higher than the LOQ. The results demonstrated that the procedure was suitable for simultaneously determining these mycotoxins in cereals and could be performed for their routine analysis in mycotoxin laboratories.

The technological characteristics of lentil grains were established, the distinctive characteristics of lentil grains in comparison with well-known varieties have been determined. It was found that in the process of deep processing of lentil grain to obtain a protein isolate, proteins retain their native conformation, as evidenced by the position of the absorption bands Amide I, Amide II and Amide III in the analysis of IR spectra.

Uses of multigrain for functional ice cream cone

A study was conducted to understand the acceptance of blended healthy gluten-free high protein flour; we aimed to standardize an innovative, preservative-free, simple, and nutritional that is cost-effective. Grains are a staple and major part of the human diet. Multigrain products are made by combining more than two grains. They give more nutrients. They give more than regular single grain consumption and fulfill deficiencies of nutrients of other grains. The study explored Whole wheat flour, Millet, Oats, Quinoa and Amaranth. Without whole wheat flour develop an ice cream cone. Processing of grains may lead to the destruction of nutrients from grain therefore different types of grain are mixed to make multigrain food products. Bioactive compounds are fatty acids, minerals, vitamins, prebiotics, probiotics, dietary fiber, carotenoids, enzymes, antioxidants, and phytochemicals. These bioactive compounds help in the prevention of various chronic diseases as well as keep your body healthy. In this review, I discuss multigrain product and their nutrition, the product designed was multigrain flour, the effect of processing on grains and their health benefits. The study explored multigrain flour to develop an ice cream cone. The product was developed under laboratory conditions, standard steps were followed to develop the product. The Evaluation was performed on sensory attributes like Appearance, color, taste, texture, aroma, and overall acceptability of the product. In the preparation of ice-cream cones yield %, baking time, and ice cream holding time were investigated. Microbial analysis was carried out for validation of its shelf life. Our other vital focus was on the packaging and nutritional labeling.

Mineral and nutritional assessments of soybean, buckwheat, spelt, and maize grains grown conventionally and organically

The present work determined complete mineral profile of four different types of grains (spelt, soybean, maize, and buckwheat) grown under two growing systems – conventional and organic. The contents of 20 macro-, micro- and trace elements were analysed in the examined grains by inductively coupled plasma-optical emission spectrometry (ICP-OES). In most samples, nine elements were present in concentrations higher than 10 mg/kg. The remaining elements were present at lower concentrations or in traces or not detected in certain samples. Aluminium and arsenic, as two toxic elements, were detected only in organic buckwheat grains. Based on the obtained results for the mineral contents, a nutritive assessment of the quality of grains of spelt, soybean, maize, and buckwheat were made. Results of nutritional assessment showed that spelt, soybean, and buckwheat grains could potentially be good sources of several minerals for human diet. On the other hand, the presence of some toxic elements, such as cadmium and strontium, should be monitored. Results of principal component analysis (PCA) and hierarchical cluster analysis (HCA) shown that the mineral composition, to a much greater extent, depended on the botanical origin of grains as compared to the production system.
