The current study evaluated the key characters of aroma composition in diversified red wines (Cinsaut, Grenache, Cabernet Franc, Petit Verdot, Cabernet Sauvignon, Nielluccio, Tempranillo, Syrah, Merlot and Caladoc). Out of hundreds of volatile compounds 64 compounds were considered for study. Different groups consisting of fatty acids, volatile alcohols, aldehydes, esters, volatile phenols and terpenes were analysed using gas chromatography mass spectrometry coupled with thermal desorption (TD-GC-MS). Among all these diversified classes, alcohols were found as the most dominant group followed by esters and acids whereas aldehydes, phenols and terpenes were found to be minor compounds. Among the varieties, Nielluccio wine recorded highest concentration of total volatile compounds (191.53 mg/L) while, it was least in Caladoc wines (15.45 mg/L). The principal component analysis clearly differentiated Grenache wines based on their relationships between scores and their aroma composition followed by Nielluccio and Cinsuat wines. Out of sixty four compounds, only six aromatic compounds viz. butanediol, isoamyl actate, gamma-Terpene, butanol, acetic acid and furfural have satisfying aroma descriptors with floral and fruity nuances and contribute to differentiate the Grenache wines from other varieties which have similar scores in PC1 analysis. The cluster analysis also suggested that the wines in the same group (Cinsaut, Tempranillo and Syrah), (Cabernet Franc, Cabernet Sauvignon, Caladoc and Merlot) and (Nielluccio and Petit Verdot) had similar aroma characterization. Grenache wines were well differentiated from the sub group formed by other red varieties.

I found the field of Biochemistry & Molecular Biology; Chemistry very interesting. Saw the article Investigation of Lactones as Innovative Bio-Sourced Phase Change Materials for Latent Heat Storage published in 2019.0. COA of Formula: C13H8O2, Reprint Addresses Stamatiou, A (corresponding author), Lucerne Univ Appl Sci & Arts, Competence Ctr Thermal Energy Storage TES, CH-6048 Horw, Switzerland..

In the presented work, five bio-based and bio-degradable cyclic esters, i.e. lactones, have been investigated as possible phase change materials for applications in latent heat storage systems. Commercial natural lactones such as epsilon-caprolactone and gamma-valerolactone were easily purchased through chemical suppliers, while 1,2-campholide, oxa-adamantanone and dibenzochromen-6-one were synthesized through Baeyer-Villiger oxidation. The compounds were characterized with respect to attenuated total reflectance spectroscopy and gas chromatography coupled with mass spectroscopy, in order to confirm their chemical structures and identity. Subsequently, thermogravimetric analysis and differential scanning calorimetry were used to measure the phase change temperatures, enthalpies of fusion, degradation temperatures, as well to estimate the degree of supercooling. The lactones showed a wide range of phase change temperatures from -40 degrees C to 290 degrees C, making them a high interest for both low and high temperature latent heat storage applications, given the lack of organic phase change materials covering phase change temperature ranges below 0 degrees C and above 80 degrees C. However, low enthalpies of fusion, high degrees of supercooling and thermal degradations at low temperatures were registered for all samples, rendering them unsuitable as phase change materials.

Green-ripe pineapples are shipped overseas by sea freight, while those picked at full maturity need to be transported by airfreight over the same large distance. In this study, fresh-cut pineapple cubes were assessed two, five, and eight days after processing from green-ripe pineapples after mimicked sea freigh (SF) and fully ripe air-freighted (AF) pineapples. The sea-freighted samples displayed elevated titratable acidity (TA), thus resulting in smaller ratios of total soluble solids and TA compared to the AF pineapples. Differences in the carotenoid levels of the two fresh-cut categories were found to be insignificant. By contrast, hierarchical cluster analysis (HCA) and principal component analysis (PCA) calculated on the basis of the volatiles analysed by headspace solid-phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GC-MS) permitted to distinguish all six individual sample types and to segregate them into two major clusters (SF and AF). The effect of storage on the volatiles was further evaluated by partial least squares (PLS) regression. Substantial chemical markers to differentiate the individual samples and to describe the effect of storage were deduced from the PCA and PLS regression, respectively. In general, fresh-cut products obtained from fully ripe AF fruit displayed higher concentrations of volatiles, in particular, increased concentrations of diverse methyl esters. With progressing storage duration, the concentrations of ethanol and diverse ethyl esters increased. Moreover, products from AF pineapples displayed lower microbial counts compared to those from SF fruit.

Herbs market is constantly growing worldwide, and is trying to find new species and varieties coming from specific geographical regions. While the increasing production demands novel solutions for product preservation, consumers demand guaranteed quality for these products. In case of herbs, the most common preservation method is thermo-based process – drying, which strongly affects products quality. Regarding the technological possibilities and efficiency, convective drying (CD), microwave drying, vacuum-microwave drying (VMD) and combined convective pre-drying followed by vacuum-microwave finish-drying (CPD-VMFD) methods are the most popular ones. In this study, the influence of the drying methods (CD, VMD and CPD-VMD) on Thai basil (O. basilicum var. thyrsiflora) quality was evaluated for the very first time. The chemical composition of their essential oils (EOs), dried samples (aroma profiles, APs) and sensory quality of the dried products were also studied. As a result of multiple chemical and sensory analyses and after cross-checking all these results, guidelines for chemical markers of Thai basil aroma quality were established. Odour-active compounds (OACs) contribution in Thai basil EOs did not show a clear pattern to link it with quality assessments; however, OACs contribution in APs did. The drying treatments leading to the dried products with the highest quality were: (i) 2 h CPD at 50 degrees C followed by VMFD with 360 W (2 h CPD50) and (ii) 1 h CPD at 70 degrees C followed by VMFD with 360 W (1 h CPD70).

Catalytic conversion of lignin to versatile aromatic compounds is attracting increasing attention. However, it is highly desirable but challenging to produce a specific chemical with high yield through lignin depolymerization in a one-pot process because of the complex structure of the lignin molecule (mainly composed of H, G, and S units). In this study, a series of metal-based deep eutectic solvents (M-DESs) were prepared and used for the catalytic tailoring of lignin H units to produce value-added methyl p-hydroxycinnamate (MPC). In particular, M-DES ChCl[FeCl3](2) showed excellent catalytic performance for the selective production of MPC as the sole product with high yield and selectivity (105.8 mg g(-1) and 74.1%, respectively). Extensive characterizations using 2D HSQC NMR, C-13 NMR, and GPC demonstrated that MPC was obtained from the selective tailoring of p-coumaric acid (pCA) units via the cleavage of ester bonds in lignin. Furthermore, M-DES ChCl[FeCl3](2) also exhibited efficiency to other herbaceous lignins, and showed excellent recyclability. Therefore, this work provides an effective strategy for the valorization of lignin.

A method for the semi-reduction of alkynoic acids through an alpha-borylation and subsequent protodeborylation mechanism has been developed. The transition metal-free protocol is achieved through the activation of bis(pinacolato)diboron by an in situ generated carboxylate moiety yielding aryl acrylic acids. Our studies demonstrate an unprecedented dual role for the carboxylate anion that involves the activation of the diboron reagent and a directing effect in the alpha-borylation. (C) 2019 Elsevier Ltd.

Regioselectivity for intramolecular Diels-Alder (IMDA) reactions of 6-acetoxy-6-alkenylcyclohexa-2,4-dien-1-ones that were formed by oxidation of 2-alkenylphenols with lead tetraacetate in acetic acid were studied. Bridged regioselectivity was observed in the IMDA reactions of 6-acetoxy-6-alkenylcyclohexa-2,4-dien-1-ones having a dienophile part which could conjugate with an aromatic group. Bridged seven-and eight-membered rings and bicyclo[2.2.2]octane skeletons were constructed by the present IMDA reactions. Density functional theory (DFT) calculations suggested that conjugation of the dienophile with neighboring aromatic groups lowered the highest occupied molecular orbital-lowest unoccupied molecular orbital (HOMO-LUMO) energy gap and preceded bridged [4 + 2] adducts.

The presence of different aldehydes is found to have a significant influence on the catalytic performance when using PN(H)P type ligands for dehydrogenation of alcohols. Accordingly, hybrid multi-dentate ligands were discovered based on an oxygen-transfer alkylation of PNP ligands by aldehydes. The relevant Ru-PNN(PO) system provided the desired unsymmetrical esters in good yields via acceptorless dehydrogenation of alcohols. Hydrogen bonding interactions between the phosphine oxide moieties and alcohol substrates likely assisted the observed high chemoselectivity.
