Development of volatile compounds fingerprints by headspace-gas chromatography-ion mobility spectrometry in concentrated tomato paste and distillate during evaporation processing

Volatile profiles of fresh tomato pulp, concentrated pastes and distillates during evaporation were analysed by headspace-gas chromatography-ion mobility spectrometry (HS-GC-IMS), and volatile fingerprints were established. Topographic plots showed ninety signal peaks, forty-two peaks (monomers and dimers) for twenty-five compounds were identified, including four alcohols, ten aldehydes, eight ketones, two esters and a furan. The fingerprints showed clear differences. After evaporation, phenylacetaldehyde, pentanal, 2-pentanone, 3-methylbutanal and benzaldehyde were newly detected in the concentrated pastes and distillates, while 2-heptanol, octanal, isopropyl acetate and 2-pentylfuran were no longer detectable. Prolonged evaporation caused volatile components in both pastes and distillates to decrease; most were evaporated into distillates, including all alcohols and esters, most aldehydes and some ketones. The fresh pulp, concentrated pastes and distillates were clearly distinguished by principal component analysis and hierarchical clustering analysis. This work provides a theoretical reference for tomato paste processing and the utilisation of distillate discarded.

Production of biodiesel by Burkholderia cepacia lipase as a function of process parameters

Despite the already established route of chemically catalyzed transesterification reaction in biodiesel production, due to some of its shortcomings, biocatalysts such as lipases present a vital alternative. Namely, it was noticed that one of the key shortcomings for the optimization of the enzyme catalyzed biodiesel synthesis process is the information on the lipase activity in the reaction mixture. In addition to making optimization difficult, it also makes it impossible to compare the results of the independent research. This article shows how lipase intended for use in biodiesel synthesis can be easily and accurately characterized and what is the enzyme concentration that enables achievement of the desired level of fatty acid methyl esters (FAME) in the final product mixture. Therefore, this study investigated the effect of two different activity loads of Burkholderia cepacia lipase on the biodiesel synthesis varying the pH and temperature optimal for lipase activity. The optimal lipase pH and temperature were determined by two different enzyme assays: spectrophotometric and titrimetric. The B. cepacia lipase pH optimum differentiated between assays, while the lipase optimally hydrolyzed substrates at 50 degrees C. The analysis of FAME during 24 hr of biodiesel synthesis, at two different enzyme concentrations, pH 7, 8, and 10, and using two different buffers, revealed that the transesterification reaction at optimal pH, 1 hr reaction time and lipase activity load of 250 U per gram of reaction mixture was sufficient to produce more than 99% FAME.

A green, simplified, and efficient experimental setup for a high-throughput screening of agri-food by-products – From polar to nonpolar metabolites in sugarcane solid residues

From an environmental perspective, searching for useful compounds in agri-food by-products by employing inefficient and polluting analytical procedures is paradoxical. This work aimed to develop a green, simplified, and highly efficient experimental setup for extracting and tentatively identifying the broadest range of metabolites in sugarcane solid by-products collected directly within the industrial mills. Nine different extraction approaches were investigated side-by-side, including three reference methods. Based on the extraction and environmental performances assessed by two complementary metrics called Analytical-Eco Scale and the Analytical Greenness Calculator, it was possible to reach two highly efficient two liquid-phase extractions while avoiding harmful solvents and traditional time, energy, and solvent consuming sample preparation steps, such as solvent evaporation, metabolite concentration, re-suspension, and derivatization. The simultaneously produced hydroethanolic and n-heptane extracts were directly analyzed by ultra-high-performance liquid chromatography and gas chromatography, both coupled to mass spectrometry, respectively, leading to the annotation of a large dynamic range of compounds from information rich spectral data. Up to 111 metabolites were identified in a single matrix, from highly polar sucrose to nonpolar wax ester C53 in a single extraction. Orientin, apigenin-6-C-glucosylrhamnoside, 1-octacosanol, octacosanal, and other bioactive compounds were identified in these abundantly available by-products, which are currently just burned to produce energy. The best two methods developed here (Two-Liquid-Phase Ultrasound-Assisted Extraction with Probe and Two-Liquid-Phase Dynamic Maceration) appeared as a green, simplified, and highly efficient procedures to qualitatively profile metabolites in complex solid matrices.

Mesomorphism of novel stilbene-based bent-core liquid crystals

A series of asymmetric bent-core liquid crystals, bearing the stilbene moiety in the side wing, was synthesised and characterised. Structural modifications of the non-stilbene wing resulted in formation of various mesophases. Compounds 1 and 3 with an ester linking group between the phenyl rings in this wing have an enantiotropic non-polar smectic-type mesophase, while compound 2, incorporating the biphenyl moiety, has a ferroelectric SmCaPF phase. The molecules of 2 undergo photoisomerisation in solution under UV irradiation, while the mesophases are unstable and UV irradiation leads to irreversible changes. The mesophases of 1 and 3 do not show any electro-optical switching and polarisation current. Applying low frequency AC voltage on a planarly aligned film of compound 2, smectic domains grow, while the birefringence and an image flickering increase. The observed features of these compounds identify stilbene as an attractive moiety in the design of advanced materials based on bent-core molecules.

In vitro kinetic release study, antimicrobial activity and in vivo toxicity profile of a kojic acid ester-based nanoemulsion for topical application

Nanoemulsions have emerged as novel vehicles for drug delivery that allow sustained or controlled release for topical application. In this study, kojic acid ester-based nanoemulsion (KAE-NA) was analyzed for in vitro permeation evaluation, kinetic release study, in vitro antimicrobial activity and in vivo toxicity profile on embryonic zebrafish (Danio rerio). Based on KAE-NA in vitro permeation evaluation, the percentage of permeation was significantly improved from 4.94% at 1 h to 59.64% at 8 h of application. The permeation rate of KAE-NA at 8 h was 4659.50 mu g cm(-2) h(-1) (initial concentration, C-0 = 2000 mu g mL(-1)) with a permeability coefficient (K-p) value of 0.48 cm h(-1). The kinetic release analysis showed the Korsmeyer-Peppas model was the best fitted kinetic model with high linearity [R-2 = 0.9964]. Antimicrobial activity of KAE-NA was studied against the skin pathogen bacteria Staphylococcus aureus ATCC 43300. The results indicated that the inhibition zone size of the KAE-NA (8.00 +/- 0.0 mm) was slightly bigger than that of its active ingredient, kojic acid ester (6.5 +/- 0.0 mm). The toxicity profile of KAE-NA on embryonic zebrafish revealed less toxicity with LC50 (50% lethal concentration) more than 500 mu g mL(-1). The survival rate of the embryonic zebrafish was more than 80% when treated at doses ranging from 7.81-250 mu g mL(-1) and showed normal development throughout the experiment without any observed deformation. Hence, KAE-NA proved to be less toxic on the embryonic zebrafish.

Design and Experiment of Polyimide/Ti Wire Composite with the Interface Chemically Grafted through Carbon Nanotubes

Herein, an efficient method is proposed to develop polyimide (PI)/titanium (Ti) wire composite with the interface chemically grafted through carbon nanotubes (CNTs). In order to reduce the research cost and blindness, nine strategies are designed herein to improve the interface compatibility of PI/Ti by using the simulation approach, and then an ideal solution is obtained to prepare the new composite material. The PI/Ti simulation model with interface grafted using different CNTs functionalized through ester and amide bonds is established. It is found that the interface cohesive energy can be improved by 276.7% by grafting -COOH@MWCNTs through ester bond. Then, based on the simulation results, the PI/Ti wire composite with the interface chemically grafted through -COOH@MWCNTs is prepared successfully, which exhibits an increase of 243.3% in interface shear strength (IFSS). Furthermore, the result also indicates that when the orientation of grafted -COOH@MWCNTs is perpendicular to the Ti surface, its interface performance achieves the maximum with an IFSS increase of 301.3%. This method can also be used to improving the interface performance of Ti/Cf/polymerized monomer reactant (PMR) polyimide hybrid composite laminates (also known as TiGr).
