Volatile composition and sensory and quality attributes of quince (Cydonia oblonga Mill.) fruits as affected by water stress

No information exists on the effect of water deficit on quince (Cydonia oblonga Mill.) fruit quality characteristics. In this paper, the effect of withholding irrigation water in the middle of the rapid fruit growth period on yield, main fruit physicochemical characteristics, sensory profile, and volatile composition of quince (cv. BA-29) was studied. The linear fruit growth phase was seen to be a critical phenological period for the marketable yield of quince because water deficit decreased the fruit weight, size, and moisture content. Also, this period was clearly critical for the fruit’s chemical characteristics. Water deficit induced important changes in an important number of the identified volatile compounds, characterized by decreases on pear, pineapple and apple sensory descriptors and increases on the green-herbaceous sensory descriptors. Moreover, total soluble solids increased and the total polyphenols content and antioxidant activity decreased as a result of water deficit effect, even though the still high levels of total polyphenols, regardless of the fruit water status, suggested that quinces can be used as an important source of natural antioxidants. The fruit sensory analysis indicated that the peel colour intensity of fruits from the water deficit treatment increased and fruit flesh texture improved. Indeed, the main handicaps for its consumption as fresh fruit (corkiness and fibreness) severely decreased and crunchiness increased.

Design, synthesis, and antifungal activity of inhibitors of brassilexin detoxification in the plant pathogenic fungus Leptosphaeria maculans

Potential inhibitors of Leptosphaeria maculans mediated detoxification of the phytoalexin brassilexin were designed and synthesized based on the planar heteroaromatic structure of isothiazolo[5,4-b]indole. Screening of these compounds for inhibition of brassilexin detoxification in cultures of L. maculans indicated that 4-(2-chlorophenyl)isothiazole had the largest effect on the rate of brassilexin detoxification. However, the most antifungal compound among the potential inhibitors, isothiazolo[5,4-b]quinoline, did not appear to affect the metabolism of brassilexin noticeably, suggesting that growth inhibition is not sufficient to slow down the rate of brassilexin detoxification. Furthermore, it was determined that 4-arylisothiazoles as well as isothiazolo[5,4-b]thianaphthene displayed antifungal activity against L. maculans.

Removal of pollutants and reduction of bio-toxicity in a full scale chemical coagulation and reverse osmosis leachate treatment system

Removals of pollutants and toxic organic compounds and reduction in bio-toxicity of leachate along an operating full-scale leachate treatment system utilizing chemical coagulation, sand filtration, microfiltration (MF) and reverse osmosis (RO) membrane were evaluated. High pollutant removals were achieved mainly by coagulation and sand filtration. Major toxic organic pollutants, i.e. DEHP, DBP and bisphenol A were removed by 100%, 99.6% and 98.0%. Acute toxicity test using water flea, Nile Tilapia and common carp and genotoxicity (Comet assay) were conducted to determine toxicity reduction in leachate along the treatment. Ammonia was found to be the main acute toxic compounds in leachate as determined by LC50 but the effect of organic substances was also observed. DNA damage in fish exposed to diluted raw leachate (10% of LC50) was found to be 8.9-24.3% and it was subsequently decreased along the treatment. Correlation between pollutants and its bio-toxicity was established using multivariable analyses.

Meta-analysis of the core aroma components of grape and wine aroma

Wine aroma strongly influences wine quality, yet its composition and its evolution during the winemaking process are poorly understood. Volatile compounds that constitute wine aroma are traditionally divided into three classes according to their origin: grape, fermentation, and maturation aroma. We challenge this view with meta-analysis and review of grape and wine volatiles and their precursors from 82 profiling experiments. We compiled a list of 141 common grape and wine volatiles and quantitatively compared 43 of them. Our work offers insight into complex relationships between biosynthesis of aroma in grapes and the changes during the winemaking process. Monoterpenes are one of the largest and most researched wine aroma compounds. We show that their diversity in wines is mainly due to the oxidative metabolism of linalool in grapes. Furthermore, we demonstrate that most of the linalool produced in grapes is converted to these oxidized derivatives.

SPME/GC-MS characterization of volatile compounds of Chinese traditional-chopped pepper during fermentation

Fermented-chopped pepper is a traditional-fermented vegetable in China. Chopped pepper is generally made with pepper, garlic, and ginger. In present study, the volatile compounds, obtained from chopped peppers during spontaneous fermentation, were analyzed by solid-phase microextraction (SPME) and gas chromatography-mass spectrometry (GC-MS). One hundred and forty volatile compounds were identified by solvent-assisted flavor evaporation, including 42 hydrocarbons, 34 esters, 16 alcohols, 21 aldehydes, 8 acids, 4 ketones, 4 ethers, and 9 other compounds. Alcohols, esters, and ketones were the dominant volatile fractions. The terpenes were found to be the main contributors to chopped pepper samples. It is important to note that among terpenes, such as beta-phellandrene, alpha-curcumene, elemene, geraniol and nerolidol may originated from ginger. In addition, diallyl disulfide and diallyl sulfide, the two major sulfur components, may originated from garlic volatile oils. The results indicated that the ginger and garlic as raw materials played an important role in the flavor of chopped pepper. The contents of esters significantly increased during the fermentation process, the ethyl palmitate and ethyl linoleate were the main esters. The content of beta-ionone as an degradation compound of carotenoids increased significantly with the fermentation period. Principal component analysis (PCA) was applied to discriminate the fermented-chopped peppers samples according to different times, and the fermented-chopped pepper samples were clearly differentiated on PCA plots. The fermentation stage was mainly affected by esters, alcohols, aldehydes and terpenes.

Reactions of [Ru3(CO)12] with thiosaccharin: Synthesis and structure of di-, tri-, tetra- and penta-ruthenium complexes containing a thiosaccharinate ligand(s)

Reactions of [Ru3(CO)12] with thiosaccharin (tsacH) at different temperatures have been investigated. At 40 C, the diruthenium complex [Ru2(CO)6(mu-N,S-tsac)2] (1) is produced and whose ruthenium atoms are bridged by two tsac ligands that are oriented in a head-to-tail fashion. When this reaction is carried out at 66 C, the tri-, tetra- and penta-ruthenium complexes [H2Ru3(CO)7(mu-N,S-tsac)(mu-C,N?C6H4CNSO2)(mu3-S)] (2), [Ru4(CO)12(mu-N,S-tsac)2(mu4-S)] (3) and [H2Ru5(CO)13(mu-N,S-tsac)(mu-C,N?C6H4CNSO2)(mu3-S)(mu4-S)] (4), respectively, are also isolated in addition to 1. The triruthenium complex 2 exhibits an arachno SRu3 polyhedron containing edge-bridging tsac and C6H4CNSO2 ligands. The tetraruthenium complex 3 consists of two [Ru2(CO)6(mu-N,S-tsac)] fragments linked via a mu4-S ligand, while the pentaruthenium complex 4 is composed of individual Ru3 and Ru2 units linked via a mu4-S ligand. At 81 C, the same reaction furnishes the pentaruthenium complex [HRu5(CO)15(mu-N,S-tsac)(mu5-S)] (5) containing tsac and mu5-S bridging ligands. The molecular structures of the new complexes have been determined by single-crystal X-ray diffraction analyses, and the bonding in each product has been examined by DFT.

First observation of Chapman rearrangement of a pseudosaccharyl ether in the solid state: the thermal isomerization of 3-(methoxy)-1,2-benzisothiazole 1,1-dioxide revisited

3-(Methoxy)-1,2-benzisothiazole 1,1-dioxide, a pseudosaccharyl ether, was long ago known to undergo a thermal Chapman-like [1,3?]-isomerization to the corresponding N-methyl pseudosaccharin at temperatures above its melting point (ca. 184 C) [Hettler H., Tetrahedron Lett. 1968, 15, 1793]. In the present study, it is shown that this rearrangement can also take place in the solid state, at temperatures as low as 150 C. This was the first observation of a Chapman-like [1,3?]-isomerization in pseudosaccharyl ethers in the solid state. The study has been carried out by a multidisciplinary approach using temperature dependent infrared spectroscopy, differential scanning calorimetry (DSC), and polarized light thermomicroscopy, complemented by theoretical methods.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 18712-14-6 is helpful to your research. Safety of 3-Methoxybenzo[d]isothiazole 1,1-dioxide
