Abstract:

Food color is the first attribute evaluated by the consumer. Therefore, the food industry is concerned about the use of colorants in food materials to make them more attractive. Between the colorants used by the food industry, annatto is a raw material that allows the obtaining a large amount of natural pigments. The annatto dye is extracted from the outer layer of Bixa orellana L. seeds by immersion in alkaline solution, vegetable oil or organic solvents. In addition to the commercial preparations, a large amount of brazilian annatto seeds is used to prepare &ldquo;color&iacute;fico&rdquo;, a spice obtained from the mixture of pigment or grinded seeds with corn flour, vegetable oil and salt. Besides the bixin carotenoid, the seeds presents other components such as geranylgeraniol, with important pharmacological properties. The annatto seeds variability are influenced by conditions of post-harvest processing and the different cultivars used in industry. After the annatto processing, about 96% of waste are generated, which after dried and milled remain appropriate for reuse. During de pigment analysis in foodstuffs, the preparation techniques, the compounds separation and quantification requires, the use of standards with high purity and stability.&nbsp;DOI: 10.14685/rebrapa.v6i1.144

Abstract:

Growing public concerns about health haves prompted the search for novel food sources. The study is focused on the seeds, sprouted seeds and microgreens of Trifolium pratense, T. medium, Medicago sativa, M. lupulina, Onobrychis viciifolia, Astragalus glycyphyllos and A. cicer species as a potential source of value-added food ingredientsr. The samples were analysed for nutritional (wet chemistry, standard methods) and mineral (atomic absorption spectroscopy, UV-Vis spectrophotometry) profiles, isoflavones (ultra-performance liquid with diode array detector –UPLC-DAD), coumestrol (UPLC-DAD), condensed tannins (CT) (vanillin-H2SO4 assay) and triterpene saponins (UPLC with triple-stage quadrupole MS). In our study, each species displayed high, but species-dependent nutritional, mineral and phytochemical value. All counterparts of legumes were mineral and protein rich. A. glycyphyllos samples, especially seeds, were abundant in iron. Trifolium spp. were found to be important sources of isoflavones, Medicago spp. of coumestrol and saponins, and O. viciifolia of CT. The protein and phytochemical contents increased and total carbohydrates decreased from seeds to microgreens.Our findings proved for the first time that seeds, sprouted seeds, and especially microgreens of small-seeded legumes are promising new sources of ingredients for fortification of staple foods with bioactive compounds, minerals and nutrients.

Abstract:

Abstract Dietary fiber sometimes is defined chemically as nonstarch polysaccharides plus lignin or as other specific chemical entities. Analysis of dietary fiber according to a chemical definition typically involves gas chromatography, which allows separation and quantitation of chemical constituents that are added to arrive at a dietary fiber value. Other definitions of fiber are broader, defining it to be whatever is not digested in the alimentary tract. Analytically, this definition translates into the gravimetric sum of the material remaining after a series of enzymatic and chemical treatments that simulate in vivo digestion. Various methods reflect the gravimetric definition, which might include as dietary fiber some protein, resistant starch, and even lipids that are not digested by particular assay conditions. We used a recently proposed bile-enzymatic-gravimetric assay for total dietary fiber on commonly consumed seeds (hulled and unhulled sesame, caraway, and poppy) and visually found these seeds to be undigested. We then determined the impact of the undigested seeds on measured dietary fiber content by spiking homogenized daily menus with 5% by weight of these seeds and calculating recoveries with 2 assumptions: seeds are 100% fiber because they are not digested, and the fiber content of seeds is as determined by assay. Calculated recoveries were very different depending on which assumption was made (71-90% or 99109%, respectively), and the difference was closely related to the seed’s protein content.

Abstract:

The date seed is a by-product from the date industry. Its use as a source of added-value compounds is of great interest. Oil accounts for 5-13% of the seed’s weight. Soxhlet extraction with organic solvents is the traditional method for obtaining oil from seeds. In this work, hydrothermal pre-treatments and sonication are proposed to make the extraction a more environmentally friendly process. Factors such as sonication time and temperature and hexane-to-seed ratio (H/S) have been considered. Response surface methodology was applied for optimization. Hydrothermal treatments increased oil recovery. H/S was the most influential factor, and was close to 7 mL/g seeds for both samples. 71% recovery was achieved for native seeds after 15 min sonication at 45 ºC, and 80% for 180 ºC-treated seeds after 45 min at 35 ºC when compared to Soxhlet extraction. These conditions comply with our initial aim. Pre-treatments seem to have a negative effect on oil stability, although this observation needs to be confirmed.

Abstract:

The present work aimed to characterize the molecular relationships between structure and function of the seed storage protein β-vignin, the vicilin storage protein of cowpea (Vigna unguiculata, l. Walp) seeds. The molecular characterization of β-vignin was carried out firstly by assessing its thermal stability, under different conditions of pH and ionic strength, by thermal shift assay (TSA) using SYPRO Orange fluorescent dye. Secondly, its aggregation propensity was evaluated using a combination of chromatographic and electrophoretic techniques. Two forms of β-vignin were considered: the native form purified from mature quiescent seeds, and a stable breakdown intermediate of 27 kDa produced while seeds germinate. TSA is a useful tool for determining and following over time the structural changes that occur to the protein during germination. The main result was the molecular characterization of the 27 kDa intermediate breakdown polypeptide, which, to the best of our knowledge, has never been described before. β-vignin seems to retain its trimeric conformation despite the evident degradation of its polypeptides.

Abstract:

The world’s energy matrix can be diversified with biodiesel from castor and jatropha oil. Hence, the objective of this study was to assess a conversion path for the valorization of castor and jatropha seeds. The results showed the maximum extraction of castor oil at 90 °C, 2 rpm, and 6 mm nozzle, achieving a yield of 36.97% and for jatropha oil at 100 °C, 1.5 rpm, and 10 mm nozzle, achieving a yield of 20.11%. The acid value and cloud point of castor and jatropha oil were 0.797 and 23.44 mg KOH/g, 10±1 °C and 12±0.55 °C, respectively; while the pour point was -3 °C for both. The acid value and cloud point for biodiesels ranged from 0.26-0.43 mg KOH/g, and -12.50-6.10 °C, respectively. The viscosity of oils and biodiesel ranged from 0.02-1.3 P. GC-MS indicated 66.38% of methyl ricinoleate in castor biodiesel and 31.64% of methyl oleate in jatropha biodiesel. The HHV for castor and jatropha biodiesel ranged from 32.37-40.25 MJ/kg.

Full text

Abstract:

The effect of crystal seeds on calcium carbonate (CaCO3) cluster formation in aqueous solution is of interest in the fields of geochemistry, inorganic chemistry, atmospheric science, biomedicine, biomineralization, and tissue engineering. Due to an instantaneous and microscopic process, it is still experimentally challenging to directly capture the CaCO3 pre-nucleation. This study employed reactive force field (ReaxFF) molecular dynamics simulations to explore the variation among CaCO3 ion pairs in an aqueous solution with or without crystal seeds. The results show that the addition of crystal seeds can improve CaCO3 ion pair formation. We found that the surface of the calcite phase, compared with the metastable vaterite phase, prefers to attach the ion pairs from solution via proton transfer. This work sheds light on the effect of different crystal seeds on CaCO3 ion pair formation as a precursor of pre-nucleation clusters.

Abstract:

The creative comparisons prospective chemistry teachers make about “chemistry” and the “chemist” may reflect how they perceive these concepts. In this sense, it seems important to determine which creative comparisons prospective teachers make with respect to these and how these can change after the history of chemistry is treated in the classroom. This study seeks to investigate the impact of the basic History and Philosophy of Chemistry course on prospective chemistry teachers’ perceptions towards chemistry and the chemist. The study was conducted during the 2012–2013 academic year at a state university in Turkey with 38 prospective chemistry teachers. A creative comparisons questionnaire and semi-structured interviews were used as data collection instruments in the study. This questionnaire was administered to the prospective teachers in the form of a pre-test, post-test, and retention test. Results of the analysis showed that the prospective teachers produced creative comparisons related to chemistry in the pre-test that mostly relied on their own experiences and observations, but that in the post-test and retention test, their comparisons mostly contained references to the role of chemistry in daily life, its development, and its facilitating aspects. Similarly, it was observed that in the pre-test, the prospective teachers made creative comparisons regarding the chemist that related mostly to the laboratory, but that the post-test and retention test rather contained the aspects of chemists as researchers, meticulous persons, facilitators and managers. Also, 18 prospective teachers were engaged in interviews to understand their prior knowledge about chemistry and the chemist, as well as the reasons for the changes in their creative comparisons. The results of the interviews indicated that a large majority of the prospective teachers were able to fully reflect on their inadequacy about their previous knowledge about “chemistry” and “chemist,” and it was seen that they could explain the reason they changed their creative comparisons as an outcome of the History and Philosophy of Chemistry course. In the light of these results, it can be said that the History and Philosophy of Chemistry course may help prospective chemistry teachers in their perceptions about both chemistry and the chemist and may add depth to their knowledge.

Abstract:

Context. Low-mass protostars drive powerful molecular outflows that can be observed with millimetre and submillimetre telescopes. Various sulfuretted species are known to be bright in shocks and could be used to infer the physical and chemical conditions throughout the observed outflows. Aims. The evolution of sulfur chemistry is studied along the outflows driven by the NGC 1333-IRAS4A protobinary system located in the Perseus cloud to constrain the physical and chemical processes at work in shocks. Methods. We observed various transitions from OCS, CS, SO, and SO2 towards NGC 1333-IRAS4A in the 1.3, 2, and 3 mm bands using the IRAM NOrthern Extended Millimeter Array and we interpreted the observations through the use of the Paris-Durham shock model. Results. The targeted species clearly show different spatial emission along the two outflows driven by IRAS4A. OCS is brighter on small and large scales along the south outflow driven by IRAS4A1, whereas SO2 is detected rather along the outflow driven by IRAS4A2 that is extended along the north east–south west direction. SO is detected at extremely high radial velocity up to + 25 km s−1 relative to the source velocity, clearly allowing us to distinguish the two outflows on small scales. Column density ratio maps estimated from a rotational diagram analysis allowed us to confirm a clear gradient of the OCS/SO2 column density ratio between the IRAS4A1 and IRAS4A2 outflows. Analysis assuming non Local Thermodynamic Equilibrium of four SO2 transitions towards several SiO emission peaks suggests that the observed gas should be associated with densities higher than 105 cm−3 and relatively warm (T > 100 K) temperatures in most cases. Conclusions. The observed chemical differentiation between the two outflows of the IRAS4A system could be explained by a different chemical history. The outflow driven by IRAS4A1 is likely younger and more enriched in species initially formed in interstellar ices, such as OCS, and recently sputtered into the shock gas. In contrast, the longer and likely older outflow triggered by IRAS4A2 is more enriched in species that have a gas phase origin, such as SO2.

Abstract:

Asparagus bean immature pods and seeds are popular as food products for healthy and functional nutrition. Gas chromatography with mass spectrometry was used to compare metabolomic profiles of seeds and pods yielded by old Chinese landraces and the modern cultivars ‘Yunanskaya’ and ‘Sibirskiy razmer’. About 120 compounds were identified. The content of a majority among groups of compounds was higher in pods than in seeds. The amount of free amino acids in pods was 47 times higher, polyols and phytosterols 5 times higher, phenolics 4 times higher, and organic acids and saponins 3 times higher than in seeds. Differences were found in the relative content of compounds. Among phenolic compounds, the dominant one for seeds was protocatechuic acid, and for pods 4-hydroxycinnamic acid. Only polyols were identified in seeds, but pods additionally contained ethanolamine, phytol, and phytosphingosine. The ratio for nonsaturated/saturated fatty acids was 2.2 in seeds and 1.4 in pods. Seeds contained more stigmasterol, and pods more β-sitosterol. Aglycones of saponins were identified: cycloartenol in seeds, α- and β-amyrins in pods. Oligosaccharides dominated in both seeds and pods. Landraces manifested higher protein content in pods, while modern cultivars had pods with higher contents of organic acids, polyols, monosaccharides, and fatty acids. The results obtained confirm the high nutritional value of asparagus bean seeds and pods, and the prospects of their use in various diets.

Abstract:

Melinjo (Gnetum gnemon L.) is a tropical plant that has an abundant distribution and it widely used in Indonesia. Study on the utilization of melinjo is began to developed in the realm of utilization as a source of medicinal compounds, especially the seeds of melinjo which so far have only been used as food. The seeds of melinjo contain secondary metabolites that are active including phenols, flavonoids, alkaloids and saponins. These compounds are anatomically produced by the secretory tissue of melinjo seeds. The distribution of the secretory tissue and the compounds produced is thought to be influenced by the maturity phase of the melinjo seeds. The maturity phase of melinjo seeds is marked by the color of the seed coat starting from the most mature, namely red, yellow, and green. In this study, histochemical tests were carried out to determine the distribution of secretory tissue in melinjo seeds and the compounds produced. In addition, antioxidant activity tests were also carried out using the DPPH method. Phenolic compounds, flavonoids, alkaloids and saponins are scattered in each layer of melinjo seeds, namely sarcotesta, sclerotesta, endotesta and endosperm at different levels in each stage of maturity. The highest antioxidant activity was in the extract of yellow melinjo seeds with an IC50 value of 24.37 g/mL. Antioxidant activity melinjo seeds are related to the composition of compounds contained in melinjo seeds.
