Chemical composition as related to seed color of common bean

This study aimed to quantify the levels of protein and minerals in common bean lines from the Germplasm Bank of Universidade Federal de Lavras and to investigate the relationship between color and the mineral and protein contents of the beans. One hundred common bean lines with carioca, black and other grain color patterns were assessed for the protein levels and the mineral contents of phosphorus, potassium, calcium, magnesium, copper, manganese, zinc, and iron. Genetic variability was detected among the different groups and also between lines within each group. In general, the protein, iron and zinc contents were highest in the black bean lines. The carioca grain was outstanding for manganese and magnesium and the other grain colors for calcium. Positive correlations between most nutrients were observed. This indicates the possibility of obtaining lines with higher nutritional value by selection.

The mineral and heavy metal contents in 17 commercially available Croatian blackberry wines were determined by FAAS/FAES and GFAAS. The concentrations of potassium, sodium, calcium, magnesium, iron, copper, manganese, zinc, cobalt, chromium, and cadmium were between (in mg/l) 924–1507, 11.81–120.10, 86.4–457.1, 183.4–381.2, 0.082–6.273, 0.058–0.767, 1.47–11.53, 0.247–6.645, and (in µg/l) 3.21–11.89, 10.08–15.88, and 0.55–9.9, respectively. A negative correlation was found between the concentrations of macro (Mg) and micro (Fe) minerals. Furthermore, positive correlations were observed between the concentrations of manganese, cadmium, and cobalt that indicated the origin of these elements in the anthropogenic source. Multivariate analyses (PCA/LDA) showed that the distinct patterns of the metal contents in blackberry wines could be identified with quite satisfactory accuracy (sensitivity and specificity) with the subregion of the origin. In regard to the results obtained, Croatian blackberry wines could be considered as safe from the health risk point of view and as a good additional source of the essential nutrients investigated such as manganese, magnesium, and potassium.

No study has been conducted to determine the mineral content of seeds belonging to different quinoa varieties under the conditions of Turkey. In addition, there is no study on whether quinoa seeds that containing high amounts of minerals can be utilized for mineral needs of laying hens in particular. In this study, which was carried out under Erzurum irrigated conditions, it was aimed to determine the mineral content of seeds belonging to nine quinoa varieties and whether they can appropriately utilize for meeting mineral requirements (as recommended by NRC) of laying hens. Significant differences were observed in the mineral contents of the varieties. The phosphorus, potassium, calcium, magnesium, iron, copper, manganese, zinc and boron contents of the seeds varied between 0.18-0.25%, 0.76-1.08%, 0.07-0.12%, 3427-5453 mg kg-1, 233.8-577.8 mg kg-1, 45.6-107.8 mg kg-1, 40.2-72.9 mg kg-1, 29.8-55.4 mg kg-1 and 48.3-94.7 mg kg-1, respectively. When these results were compared with the values recommended by NRC, it was seen that quinoa seeds could exceedingly meet the daily mineral requirements (except calcium) of laying hens. As a result, it has been revealed that the seeds of all quinoa varieties can be evaluated as an organic mineral source in the feeding of laying hens.

Yield Factor

Shellfish is a major component of our global aquatic food supply, which includes the molluscs, crustaceans and echinoderms. The aim of this study was to evaluate the weight yield factor, chemical composition and energy value in three imported shellfish species (Palinurus regius, Sepia officinalis and Farfantepenaeus notialis) in Nigeria. The physical and chemical determinations were in accordance with the official methods. The results showed that all the shellfish species had weight yield factor less than 1, and the weights obtained for the samples showed no statistically significant differences before and after boiling. In raw samples, S. officinalis had significant (p<0.05) higher protein and crude fat values of 20.41±0.63 g/100 g and 2.67±0.68 g/100 g respectively. In boiled samples, high protein levels (15.21-19.22 g/100 g) with no significant difference characterized the overall proximate profile of shellfish species studied herein. In terms of minerals, all investigated elements (calcium, magnesium, potassium, phosphorus and sodium) were generally found at lower levels in boiled samples when compared with the mineral contents of the raw shellfish samples. S. officinalis had the higher total energy value in both raw (344.94 kJ 100/g) and boiled samples (373.96 kJ 100/g). All the species can be considered as food items with interesting dietetic properties due to high contents of proteins, minerals and useful energy values. Les mollusques et crustacés sont une composante importante de notre approvisionnement alimentaire aquatique mondial, qui comprend les mollusques, les crustacés et les échinodermes. L'objectif de cette étude était d'évaluer le facteur de rendement pondération, la composition chimique et la valeur énergétique de trois espèces importées de mollusques et crustacés (Palinurus regius, Sepia officinalis et Farfantepenaeus notialis) au Nigéria. Les déterminations physiques et chimiques étaient conformes aux méthodes officielles. Les résultats ont montré que toutes les espèces de mollusques et crustacés avaient un facteur de rendement de poids inférieur à 1, et les poids obtenus pour les échantillons n'ont montré aucune différence statistiquement significative avant et après l'ébullition. Dans les échantillons crus, S. officinalis avait des valeurs significatives (p<0.05) de protéines et de matières grasses brutes de 20.41±0.63 g/100 g et 2.67±0.68 g/100 g respectivement. Dans les échantillons bouillis, des niveaux élevés de protéines (15.21-19.22 g/100 g) sans différence significative ont caractérisé le profil proximate global des espèces de mollusques et crustacés étudiées dans le présente. En ce qui concerne les minéraux, tous les éléments étudiés (calcium, magnésium, potassium, phosphore et sodium) ont généralement été trouvés à des niveaux inférieurs dans les échantillons bouillis par rapport au contenu minéral des échantillons de mollusques et crustacés crus. S. officinalis avait la valeur énergétique totale la plus élevée dans les échantillons bruts (344.94 kJ 100/g) et bouillis (373.96 kJ 100/g). Toutes les espèces peuvent être considérées comme des aliments aux propriétés diététiques intéressantes en raison de la teneur élevée en protéines, minéraux et valeurs énergétiques utiles.

Selection Of

Common bean (Phaseolus vulgaris L.) is an important source of dietary protein and minerals worldwide. Genes conditioning variability for mineral contents are not clearly understood. Our ultimate goal is to identify genes conditioning genetic variation for Zn and Fe content. To establish mapping populations for this objective, we tested mineral content of 29 common bean genotypes. Chemical analyses revealed significant genetic variability for seed Zn and Fe contents among the genotypes. Genetic diversity was evaluated with 49 primer pairs, of which 23 were simple sequence repeats (SSR), 16 were developed from tentative consensus (TC) sequences, and 10 were generated from common bean NBS-LRR gene sequences. The discriminatory ability of molecular markers for identifying allelic variation among genotypes was estimated by polymorphism information content (PIC) and the genetic diversity was measured from genetic similarities between genotypes. Primers developed from NBS-LRR gene sequences were highly polymorphic in both PIC values and number of alleles (0.82 and 5.3), followed by SSRs (0.56 and 3.0), and markers developed from TC (0.39 and 2.0). genetic similarity values between genotypes ranged from 14.0 (JaloEEP558 and DOR364) to 91.4 (MIB152 and MIB465). Cluster analysis clearly discriminated the genotypes into Mesoamerican and Andean gene pools. Common bean genotypes were selected to include in crossing to enhance seed Zn and Fe content based on genetic diversity and seed mineral contents of the genotypes.

AbstractOrganic meat products are gaining consumer interest worldwide. The aim of this study was to investigate the effect of organic and conventional meat origin on nutritional determinants of the following pork meat cuts: loin, ham, and shoulder. Nutritional value of meat was based on selected indicators such as proximate composition, the concentration of cholesterol, vitamin E content and minerals and trace elements such as calcium, magnesium, potassium, copper, iron, and zinc, and the composition of fatty acids. The results of this study demonstrated that higher contents of protein and selected mineral compounds, as well as lower vitamin E concentration and different fatty acids (i.e., C12:0, C17:0, C17:1 n-7, C18:3 n-6, C24:0 and total n-3 polyunsaturated fatty acids (PUFA)) distinguish organic pork meat cuts from the conventional counterparts. The organically meat parts, especially the shoulder, were identified as a better source of copper, calcium, iron and zinc, while organic ham and loin had more potassium. On the other hand, organic hams were shown to have lower content of vitamin E in comparison to their conventional equivalents present. Also, in organic shoulders showed a higher n-6/n-3 ratio compared to meat of conventional origin.

The diet of the majority of the population of Russia is characterized by an insufficient content of a number of micronutrients, including macro- and micronutrients. The aim of the study is to characterize in a rat model experiment the effect of combined nutritional deficiency of calcium, magnesium and iodine on the availability of other mineral substances, vitamin metabolism and biochemical parameters blood plasma. The lack of minerals in growing Wistar male rats with an initial body weight (51.4 ± 0.5) g was created for 23 days by halving of a calcium, magnesium and iodine in the salt mixture. Alimentary deficiency of calcium, magnesium and iodine in growing rats significantly and multidirectionally affected the metabolism of other minerals and vitamins, as well as a number of diagnostically significant indicators of blood and urine. In rats of the experimental group, the liver concentration of α-tocopherol, vitamin B1 and retinol palmitate decreased, the concentration of iron and zinc increased, the copper content in the whole brain decreased significantly. The molar ratio of γ- and α-tocopherols in blood plasma was increased, the concentration of the circulating form of vitamin D decreased. The ratio of AlAT / AsAT (de Ritis coefficient) markedly decreased due to increased activity of AlAT. Phosphate reabsorption decreased slightly. Increased urinary excretion of riboflavin was accompanied by a decrease in its concentration in blood plasma. The conclusion that insufficient intake of calcium, magnesium and iodine may disturb vitamin-mineral status of organism has been made.

The common bean has been object of breeding programs aiming the development of new cultivars adapted to varied production system and shown differentiated nutritional characteristics. Due a genetic diversity existent the landraces can be used directly for cropping, for present characteristics desirable. Little information exists about mineral content and other quality traits for those bean landraces. The aim of this paper was to verify the variability for grain nutricional caracters in breeding cultivars and landraces of bean from Rio Grande do Sul state, Brazil. The experiment was conducted in 2009/2010 in Experimental Station Cascata, of Embrapa Temperate Agriculture. In whole grain of 54 bean genotypes with black and no black coat were determined macroelements (nitrogen, phosphorus, potash, calcium, magnesium and sulfur), oligoelements (iron, manganese, zinc and cuprum), protein and ash content, insoluble fiber, digestive nutrient and antioxidant astragalina. The results shown that the landraces varieties presents nutritional composition of macro and oligoelements, fibers, protein and ash contents in whole grain similar than that of breeding lines and cultivars. The black coat grain from breeding programs showed better nutritional quality for macro and oligoelements content than coloured grain, highlighting TB 02-04 e TB 01-01. The landraces with coloured grains TB 02-26, TB 02-24 and TB 03-13 showed the high levels of astragaline.

Soybean mildew caused by Oomycota Peronospora manshurica, is a disease widely spread in Brazil. In order to study the efficiency of soybean mildew control due to the application of alternative products and fungicide in the field, experiments were conducted in Ponta Grossa, PR, Brazil, during the 2013/2014 and 2014/2015 growing seasons. The design used was randomized blocks with four replications. The treatments were: 1-witness; 2-acibenzolar-S-methyl; 3-calcium; 4-micronutrients: copper, manganese and zinc; 5-micronutrients: manganese, zinc and molybdenum; 6-NK fertilizer; 7-Ascophyllum nodosum and 8-azoxystrobin + cyproconazole with the addition of Nimbus adjuvant. Four applications of alternative products (phenological stages V3, V6, R1 and R5.1) and two of fungicide (phenological stages R1 and R5.1) were performed. The mildew severity was estimated using a diagrammatic scale. The severity data made it possible to calculate the area under the disease progress curve (AUDPC). In the 2014/2015 harvest the disease was more severe. The control of downy mildew by the use of fungicide did not reduce the epidemic. The fungicide was not efficient in the two evaluated seasons. All tested alternative products reduced the disease severity and AUDPC in both seasons. The best results in reducing downy mildew were found with the application of acibenzolar-S-methyl, micronutrients (Cu, Mn, Zn) and A. nodosum.
