Static supercritical fluid extraction has been used to concentrate the aroma materials of common herbs and spices. The technique has provided a higher number of components and cleaner extract than the one-step ethanol maceration. The one-step supercritical fluid extraction of the aroma compounds has been combined with their in situ adsorption in hydrophilic and hydrophobic silica aerogels. The extracts have been analyzed by a GC-MS technique and 55 aroma compounds have been identified. Most of the compounds have been adsorbed in both polar and apolar silica aerogels with no direct connection with the surface polarity. However, previously undetected compounds enriched to an analytically significant level, while others competed with each other for the active sites on the surface. Functionalized silica aerogels can be used as a new type of aroma storage materials and as selective and tuneable adsorbents for the extraction and enrichment of potentially active components from a complex matrix.

Vicinal diboration of alkyl bromides via tandem catalysis is reported. The reported reaction exhibits a broad substrate scope, good functional group compatibility, and regioselectivity. Moreover, it shows good practicality due to the easy accessibility of alkyl bromides in combination with diverse transformations of diboronates. Mechanism study indicates that terminal alkenes are generated selectively through nickel-catalyzed dehydrohalogenation of alkyl bromides followed by base/MeOH promoted diboration process to provide 1,2-diboration products.

Chromene and benzoxacyclic derivatives were efficiently synthesized from the ruthenium-catalyzed dehydrative C-H coupling reaction of phenols with alpha,beta-unsaturated carbonyl compounds. The cationic ruthenium-hydride complex was found to be an effective catalyst for the coupling and annulation of phenols with enals to form chromene products. The coupling of phenols with linear enones afforded 2,4-disubstituted chromene derivatives, whereas the analogous coupling with cyclic enones yielded 9-hydroxybenzoxazole products. The reaction of 3,5-dimethoxyphenol with PhCH=CHCDO resulted in the chromene product with a significant H/D exchange to both benzylic and vinyl positions. The most significant carbon isotope effect from the coupling of 3,5-dimethoxyphenol with 4-methoxycinnamaldehyde was observed on the a-olefinic carbon of the chromene product (C(2) = 1.067). A Hammett plot from the coupling of 3,5-dimethoxyphenol with para-substituted p-X-C6H4CH=CHCHO displayed a linear correlation, with a strong promotional effect by an electron -withdrawing group (rho = +1.5; X = OCH3, CH3, H, F, Cl). Several biologically active chromenone derivatives were synthesized by using the catalytic coupling method. The catalytic method provides an expedient synthetic protocol for the coupling of phenols with alpha,beta-unsaturated carbonyl compounds without employing reactive reagents or forming any wasteful byproducts.

The paper describes synthesis of a novel mesoporous and magnetically regenerated heterogeneous nanocatalyst with high catalytic activity. The synthesis strategy includes a one-step polycondensation reaction of melamine, formaldehyde and FeCl3 center dot 6H(2)O in a simple and sustainable manner and followed by immobilization of Pd(II) on it. Formation and properties of nanocomposite were characterized by different techniques; the results were illustrated good surface area and a well-defined mesopore structure. Also the palladium-catalyzed C-C bond formation between aryl halides and olefins was selected to survey the activity of the synthesized nanocatalyst. Central Composite Design (CCD) strategy was used to predict the optimum synthesis conditions and identify the remarkable and effective factors including temperature, period of the reaction and amount of catalyst. These results were also verified experimentally. In order to minimize systematic error, the experimental runs as a randomized fashion were accomplished.

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).
