Ubeda, Cristina published the artcileStudy of the changes in volatile compounds, aroma and sensory attributes during the production process of sparkling wine by traditional method, Recommanded Product: Methyl decanoate, the main research area is sparkling wine aroma sensory property volatile compound; Aging; Impact aroma compounds; Olfactometry; País grape variety; Sensory analysis; Volatile compounds; sparkling wine.

One of the strongest factors that affects the volatile profile of sparkling wine is the winemaking process. Here we focus on determining the effects of the second fermentation and aging on lees of sparkling wine from Pais grape variety combining different anal. techniques for the first time in sparkling wine: gas chromatog./mass spectrometry/olfactometry and sensorial anal. During the second fermentation and aging, there was a significant loss of esters that might be related to the adsorption on lees and ester volatility and chem. hydrolysis. The concentration of several compounds such as some esters (di-Et succinate, Et lactate, and Et isovalerate) increased during aging and could be used as aging markers. Vitispiranes were identified as the best norisoprenoids aging markers for young sparkling wines (12 mo of aging). Also, PCA showed that time of aging on lees affected mostly esters and terpenes. On the other hand, the diminution of fruity/floral impact odorants during aging was not perceived in sensorial trials. Our results suggest that the responsibility for fruity/floral nuances in sparkling wine might reside in a few high-impact aromatic compounds, such as Et isobutyrate, isoamyl acetate, Et hexanoate, β-phenylethanol and di-Et succinate.

de Barros Vinhal, Gabrielle Lazara Ribeiro Rodrigues published the artcileMurici (Byrsonima verbascifolia): A high bioactive potential fruit for application in cereal bars, Computed Properties of 110-42-9, the main research area is Byrsonima verbascifolia bioactive potential fruit cereal bar application.

In order to popularize and use murici fruit (Byrsonima verbascifolia) in processed foods, the aim of the study was to characterize the fresh fruit as to its antioxidant capacity, volatile and bioactive compounds and to evaluate the effect of murici content on total carotenoids and sensory attributes in enriched cereal bars. For the development of cereal bars, a Plackett-Burman design was elaborated, containing eight independent variables: glucose syrup, oats in thick flakes, corn flakes, rice flakes, dehydrated murici, soy lecithin, hydrogenated vegetable fat, and brown sugar. Fresh murici were characterized for proximate composition, total and individual carotenoids, antioxidant capacity, volatile compounds, and microbiol. anal. The murici was mainly a good source of fiber (6.4%) and lipids (7.3%), with significant levels of total carotenoids (15.3μg of β-carotene/g) and antioxidant capacity by FRAP method and ABTS method. The volatile fraction of murici mainly contains esters with descriptors such as cheese and fruity. The exptl. design used helped obtain the formulations of cereal bars with murici and demonstrated that the content of carotenoids increases as the amount of added fruit increases.

Schoneich, Sonia published the artcileDynamic pressure gradient modulation for comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry detection, Related Products of esters-buliding-blocks, the main research area is dynamics pressure modulation comprehensive gas chromatog flight mass spectrometry; Comprehensive two-dimensional gas chromatography; Dynamic pressure gradient modulation; Flow modulation; Mass spectrometry.

Dynamic pressure gradient modulation (DPGM) is studied for comprehensive 2-dimensional gas chromatog. (GC × GC) with time-of-flight mass spectrometry (TOFMS) detection. With DPGM, a com. pneumatic pulse valve is opened to introduce a suitably high auxiliary gas pressure at a T-junction connecting the 1st dimension (1D) and 2nd dimension (2D) columns during the modulation period (PM), temporarily stopping the 1D flow. The valve is then closed for the duration of a pulse width (pw) to re-inject temporally focused 1D eluate onto the 2D column for separation This flow modulation technique is compatible with TOFMS detection using a 2D flow rate of 4 mL/min for the separation of a 90-component test mixture A 25 min separation window using a PM = 1 s and pw = 200 ms for full modulation (and 100% duty cycle) provided an average 1Wb = 4.5 s and 2Wb = 130 ms for a 2-dimensional peak capacity of nc,2D = 2700 (100 peaks per min). The detector response enhancement factor (DREF) serves as a metric for the enhanced sensitivity of the modulated relative to the unmodulated 1D peaks, with DREFs ranging between 10 and 20 and about a 5-fold improvement in signal-to-noise ratio (S/N). The bilinear quality of the GC × GC data is studied using the chemometric method parallel factor anal. (PARAFAC). Since PARAFAC requires sufficiently trilinear data, the reproducibility of the 2D peak shape for a given analyte is confirmed using lack-of-fit (LOF) and percent variation (R2) metrics. The limit-of-detection (LOD) for the representative analyte hexadecane is determined using PARAFAC, providing an LOD of 0.7 ppb (±0.03 ppb) for 3 replicates. Seven heavily overlapped analytes are also fully resolved by PARAFAC down to the part-per-million (ppm) concentration level, producing reproducible spectra with a majority of spectral match values (MV) over 800 (relative standard deviation ≤ 7.1%). This study provides promising results for DPGM as a flow modulation technique compatible with GC × GC-TOFMS, providing high sensitivity data suitable for chemometric anal.

Yuan, Qian published the artcileTriptycene-based dicationic guanidinium ionic liquid: A novel stationary phase of high selectivity towards a wide range of positional and structural isomers, Product Details of C11H22O2, the main research area is triptycene derivative dicationic guanidinium ionic liquid stationary GC isomer; Aromatic and aliphatic isomers; Dicationic guanidinium ionic liquid, gas chromatography; Essential oil; Separation performance; Triptycene-based stationary phase.

This work presents a new triptycene-based dicationic guanidinium ionic liquid (TPG) as the stationary phase for gas chromatog. (GC). To knowledge, this is the 1st example of employing a dicationic guanidinium ionic liquid (GIL) for chromatog. analyses. As a result, the TPG column exhibited moderate polarity and column efficiency of 3840 plates/m and 3120 plates/m measured by naphthalene and 1-octanol at 120°, resp. Particularly, the TPG column exhibited distinctly advantageous performance for the challenging Grob test mixture and the isomer mixture of phenols and anilines over the monocationic GIL and its counterpart with dicationic immidazolium units (TP-2IL). Also, it showed higher selectivity towards the isomers of alkanes, alcs., diethylbenzenes, bromotoluenes, bromonitrobenzenes than the com. DB-35MS column. Also, the TPG column achieved improved thermal stability over the GIL column and excellent repeatability with the relative standard deviation values of 0.01-0.05% for run-to-run, 0.11-0.24% for day-to-day and 2.4-4.1% for column-to-column. Its application to GC-MS anal. of the essential oil of Mentha haplocalyx proved its good potential for anal. of complex samples.

General procedure: The succinic Gemini surfactants, dl- and meso-2,3-bis(alkyl)succinic acids, were synthesized by the oxidative coupling of enolates of fatty acid esters with copper(II) bromide according to Quermann et al. [35] and subsequent deprotection of ester groups. Following is a typical synthesis of di-tert-butyl 2,3-bis(undecyl)succinate, 2e: first of all, tert-butyl tridecanoate 1e was prepared from tert-butanol, tridecanoic acid, dicyclohexyl carbodiimide (DCC) and DMAP (0.2 equiv) in toluene under stirring at room temperature. In a dry 100 mL flask equipped with a dropping funnel, septum inlet, and magnetic stirrer, a solution of 12.5 mL of lithium diisopropylamide (2.0 M in hexane/THF) and 30 mL of dry THF were added under nitrogen. Under cooling at -78 C, 25 mmol of 1e in 10 mL dry THF was added dropwise over a period of 30 min, and then the mixture was stirred for an additional 15 min. With vigorous stirring 5.0 g of anhydrous CuBr2 powder was added all at once to the solution. After stirring for 30 min, the reaction was quenched by adding 50 mL of 1 M HCl at this temperature, and the mixture was allowed to reach room temperature. After extracting twice with hexane (75 mL each), the combined organic layer was washed with water and dried over Na2SO4. By means of a short path vacuum distillation apparatus, both unreacted ester and alpha-bromo ester (5e) were distilled off (*160 C,1 mmHg). The residue was subjected to column chromatography on silica eluting with hexane/diethyl ether(20:1) to separate dl- (dl-2e) and meso-isomers (meso-2e) at the yields of 36 and 25 %, respectively. Other dl- and meso-isomers of 2a-2g were also prepared in a similar manner, and diastereomers (dl and meso) were separated by SiO2 chromatography.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 110-42-9, its application will become more common.

Sawdust pyrolysis from the furniture industry in an auger pyrolysis reactor system for biochar and bio-oil production

This study investigated the potential of sawdust from the processing of Acacia wood for the furniture making industry to produce bio-oil and biochar in an auger pyrolysis reactor system. The necessary characterization to assess the suitability of feedstock and strategies the pyrolysis parameters was also carried out. The volatile matter, ash content, carbon content and the higher heating value of the sawdust feedstock were reported as 68.46 wt%, 1.13 wt%, 47.40 wt% and 19.33 MJ/kg, respectively, with very low nitrogen and sulfur content. The thermogravimetric (TGA and DTG) analysis of sawdust showed that the weight loss from biomass occurred in three main stages as a result of the removal of moisture and extractives, decomposition of hemicellulose, cellulose, and the lignin components. Based on the decomposition temperature window and peak conversion temperature the pyrolysis experiments were carried out in the range of 400-600 degrees C by maintaining the nitrogen flow rate, biomass feeding rate, rotation speed of the conveyer the residence time of materials and biomass particle size as 300 cm(3)/min, 180 g/h, 4.5 RPM, 5 min, and 0.5-1.0 mm, respectively. The yields of the non condensable gases, biochar and bio-oil were reported in the ranges 16.70-38.47 wt%, 29.72-51.85 wt% and 29.40-45.10 wt%, respectively. The pyrolysis products were pragmatically analyzed to evaluate the influence on yield and their properties. The higher heating values of bio-oil produced were reported in the range 28.781-29.871 MJ/kg while the pH of bio-oil indicated the strongly acidic nature with values in the range of 2.9-3.4. Chemical compounds in bio-oils were categorized as phenols, nitrogen containing compounds, guaiacols, organic acids, ketones, anhydrous sugars, esters, and aldehydes. Biochar characterization showed an energy potential comparable to those of the low ranked coals with the higher heating values reported in the range of 25.01-25.99 MJ/kg. The surface morphological characteristics and Brunauer-Emmett-Teller (BET) analysis of the biochars indicated potential for other valued applications in the adsorption, environmental, catalyst, and agricultural context.

Determining binding constants for 1:1 and 1:2 inclusion complexes of ester betulin derivatives with (2-hydroxypropyl)-beta-cyclodextrin by affinity capillary electrophoresis

The complexation of ester betulin derivatives with (2-hydroxypropyl)-beta-cyclodextrin (HP-beta-CD) was studied by mobility shift affinity CE. Electrophoretic mobility for triangular peaks was calculated using the parameter a(1) of the Haarhoff-Van der Linde function instead of the peak top time. Dependences of the viscosity corrected electrophoretic mobility on HP-beta-CD concentration were not described on the basis of only complexes with 1:1 stoichiometry due to the fact that these binding curves did not reach a plateau. However, the dependences were well described taking into account both 1:1 and 1:2 complexes. The presence of higher order equilibria was also revealed by x-reciprocal plots. The values of apparent binding constant logarithm, obtained for the first time, for 1:1 and 1:2 HP-beta-CD complexes of betulin 3,28-diphthalate and betulin 3,28-disuccinate with 95% confidence interval limits in brackets are the same within error and are equal to 4.85 (4.73-4.95), 8.56 (7.75-8.82), 4.92 (4.86-4.97), and 8.54 (8.23-8.72) at 25 degrees C, respectively. These values for 1:1 and 1:2 HP-beta-CD complexes of betulin 3,28-disulfate at 25 degrees C are 4.61 (4.57-4.64) and 7.11 (6.57-7.34), respectively. The binding constants for betulin 3,28-disulfate agree with the previously obtained results from the separation in the thermostatted capillary segment.
