Characterisation of free and glycosidically bound aroma compounds of la Mancha Verdejo white wines

The aroma of Verdejo La Mancha white wines was studied by instrumental and sensory analysis across five consecutive vintages to determine their typicity and quality. Free and glycosidically-bound aroma compounds were isolated by solid phase extraction (SPE) to later be analysed using gas chromatography-mass spectrometry (GC/MS). Seventy-four (74) free aroma compounds and thirty-six (36) bound aroma compounds were identified and quantified in La Mancha Verdejo wines oven this five year period. Based on the result, Verdejo white wines presents a complex chemical profile with a wealth of aromas in its aromatic composition. The sensory profile of Verdejo wines was evaluated by experienced wine-tasters and was characterised by fresh, citric, green apple, fruity and tropical fruit aroma descriptors. This study shows the first complete aromatic characterisation of La Mancha Verdejo white wines, also the data suggest that these wines present a great aromatic potential.

THERMAL FISSION OF HYDROXYLAMINE DERIVATIVES WITH NEIGHBOURING-GROUP-PARTICIPATION BY THIOETHER FUNCTIONS: PREPARATION OF 1,2-BENZISOTHIAZOLES

Some of the factors influencing the preparation of 1,2-benzisothiazoles from 2-(alkylthio)phenyl-substituted oximes are discussed.Good yields of 3-aryl-1,2-benzisothiazoles 4 may be obtained from readily available precursors.Reaction takes place under particularly mild conditions when a t-butylthio function is situated anti to the leaving group at oxime-nitrogen and S-N overlap is not restricted by ring-strain in the transition-state.The corresponding N-methyl-hydroxamic acid derivatives 2 give good yields of 2-methyl-1,2-benzisothiazol-3(2H)-one 13 only when a t-butylthio substituent is present, e.g. in 2f.The ethylthio- and i-propylthio-analogues 2d and 2e give the vinylthioethers 12, while the methylthio derivatives 2a-c undergo a novel rearrangement to “Pummerer” esters.The preparation of the polycyclic compounds fluoreno<9,9a,1-cd>-1,2 thiazole 7 and 2,2′-bi(2H-fluoreno<9,9a,1-de>-1,3-thiazine) 8 is described.

Volatile compounds of six species of edible seaweed: A review

Seaweeds are widely distributed throughout the world. Many seaweeds are of commercial importance with some consumed directly or used as an ingredient as they have functional, nutritional and/or organoleptic properties. Consumer acceptance of food is closely related to its sensory properties, of which flavor is of prime importance. A significant contributor to flavor is the aromatic volatile components present. This review focusses on the volatile components identified in commercially important edible macroalgae species consisting of four brown (Himanthalia elongata, Laminaria spp. including L. ochroleuca, and Undaria pinnatifida) and two red species (Porphyra umbilicalis and Palmaria palmata). In excess of 200 volatile compounds have been identified consisting of hydrocarbons, alcohols, aldehydes, ketones, acids, esters, furans, phenols and sulfur- containing compounds, among others present in minor quantities. The extraction/concentration conditions, chromatography and detection methodologies applied varied and impacted on the volatiles identified due to differences in their hydrophobicity, molecular weight and vapor pressure. This review highlights that considerable more information is required to identify volatile aromatic compounds in edible macroalgae and to identify those most likely to impact sensory perception. Such information could be used to aid new product development or widen applications of these seaweeds in the food or beverage sectors.

A new size-expanded RNA alphabet: Computational design of benzo-homologated (xtz-) isothiazole RNA and comparisons to the x-thieno RNA

Fluorescent nucleobase analogs are of great interest because of their widespread applications in nucleic acids research. In the present work, a new benzo-homologated RNA alphabet comprising xtzA, xtzG, xtzC, and xtzU was computationally designed based on the isomorphic tz-bases. The structural, electronic, and photophysical properties are studied by means of DFT and TDDFT calculations, and the effects of water solution, ribose, and base pairing on the singlet excited transitions were examined. The results are compared with those for tz-bases and xth-bases. These new base analogs can form stable Watson-Crick base pairs with natural counterparts as tz-bases and xth-bases do. Their ionization potentials and HOMO-LUMO gaps are in the middle of tz-bases and xth-bases: xth-base < xtz-base < tz-base. Furthermore, all xtz-bases are predicted to have smaller IPs and HOMO-LUMO gaps than natural bases and tz-bases, they are suggested to be candidates for applications in nanowire technology. The S1 states for all xtz-bases are revealed to be pipi* dominated by the configuration HOMO ? LUMO. In water solution, compared with tz- or xth-bases, the lowest pipi* states are about 20.06?21.91 kcal/mol red-shifted or 0.92?4.15 kcal/mol blue-shifted, respectively. Linking to ribose has negligible effects on the S1 excitation energies, but it owns a larger impact on the corresponding oscillator strengths. Base pairing and water solution as a whole has very little effects on the S1 transition energies of xtzA and xtzC, but it will red-shift those for xtzG and xtzU by 6.69 and 5.30 kcal/mol, respectively. All xtz-bases are expected to display visible fluorescence with the wavelengths predicted to be 540, 585, 524, and 506 nm for xtzA, xtzG, xtzC and xtzU, respectively, in water solution. Though structurally very similar, the excitation maxima and fluorescence emissions of xtz- and xth-bases show distinct differences, allowing them to be distinguished from each other by their spectroscopic characters The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.
