Wright, John published the artcileFlavor bites: 2-methyl 3-tetrahydrofuranthiol: application in meat, seafood, dairy, chocolate and coffee flavor formulations, Computed Properties of 57124-87-5, the publication is Perfumer & Flavorist (2009), 34(5), 16-17, database is CAplus.

A review. The application of resultant flavor, such as 2-Me 3-tetrahydrofuranthiol, in meat, seafood, dairy, chocolate and coffee flavor formulations is discussed. 2-Me 3-tetrahydrofuranthiol has, to a large extent, the most powerful and authentic cooked beef character of the whole series. It is also less prone to oxidation As such, flavors containing this chem. retain virtually all of their intense impact in storage. Beef flavors with higher levels of 2-methyl-3-tetrahydrofuran-thiol are particularly suitable for use in conjunction with process flavors.

Zhao, Hongfei published the artcileDevelopment of organic acids and volatile compounds in cider during malolactic fermentation, Synthetic Route of 19444-84-9, the publication is Czech Journal of Food Sciences (2014), 32(1), 69-76, 8 pp., database is CAplus.

The effect of malolactic fermentation (MLF) on the flavor quality of cider was examined Leuconostoc mesenteroides subsp. mesenteroides Z25 was used to start MLF taking place at 25°C for 12 days after the completion of alc. fermentation (AF) by Saccharomyces cerevisiae. Strain Z25 showed good activity in starting MLF of cider with 10% alc. concentration The content of malic acid, whose high concentration gives neg. organoleptic characteristics to the cider, dropped significantly from 4.0 g/l to 0.25 g/l via MLF. The concentration of lactic acid increased significantly from 0.99 g/l to 3.50 g/l, contributing to volatile acidity. The acetic acid content of the ciders was 0.74 g/l. Among 51 volatile compounds detected by GC-MS, higher alcs., esters, and carbonyl compounds were formed in ciders through MLF. The total concentration of aromatic substances doubled compared to the controls. The occurrence of MLF started by strain Z25 enabled the cider containing more volatile compounds and an acceptable adjustment of organic acids. This is the first report on using L. mesenteroides subsp. mesenteroides strain Z25 to start the MLF of apple wine improving the flavor quality of the cider produced.

Han, Jie published the artcileEffects of different storage conditions on volatile substance changes and quality of Thompson seedless grape, HPLC of Formula: 19444-84-9, the publication is Shipin Yu Fajiao Gongye (2015), 41(9), 181-187, database is CAplus.

Volatile substance of Thompson seedless grape with 3 kinds of different preservatives and combinations during 0-1°C storage was compared and analyzed by GS-MS, and its soluble solids, total acid, attachment of stem and hardness were compared. The results showed that Thompson seedless grape was packed into 3.5 kg (5 package of CT2 preservative and 1 package of CT5 preservative) had the best preserving effect. Volatile substance of Thompson seedless grape was mainly composed of aldehydes, alc. and esters, and their contents in the control group were greater than those in other treated groups. Aldehydes in T2 treated group was higher than those in other treated groups. After 60 days of storage, soluble solids, total acid, attachment of stem, and hardness were 17.64%, 0.80%, 2.59 N, 17.16% and 2.79 N. SO₂ had relatively little effect on volatile substance. T2 treatment had the best preserving effect on Thompson seedless.

Guan, Yinshuang published the artcileDepolymerization of alkaline lignin over mesoporous KF/γ-Al₂O₃, COA of Formula: C4H6O3, the publication is New Journal of Chemistry (2020), 44(34), 14411-14420, database is CAplus.

As a kind of biomass resource, lignin is the only natural renewable resource that can provide abundant aromatic compounds, which is undoubtedly considered as the best candidate to produce value-added chems. by lignin depolymerization Thus, it is of great significance to develop approaches that are able to accommodate the complex structure of lignin. Herein, an efficient depolymerization method is implemented in methanol using a mesoporous solid superbase KF/γ-Al₂O₃ catalyst. Research shows that the depolymerization of lignin is not obvious below the critical temperature of methanol, and the conversion of lignin increases significantly above the critical temperature, which can reach 60.6% at 270°C. Phenols and methoxy-substituted monocyclic aromatic compounds are predominant in the liquid products acquired by gas chromatog./mass spectrometry. Furthermore, oligomers were analyzed by time-of-flight mass spectrometry equipped with electrospray ionization. It is found that the mol. mass of the oligomers varied between 200 and 600 Da, the degree of unsaturation is mainly 4 and 8 with 1-2 aromatic rings, and the carbon number is found to be within the range of 15-30. It is speculated that the oligomers are mainly monophenyl or biphenyl compounds containing branched chains.

Zhao, Yang published the artcileA XEN-like state bridges somatic cells to pluripotency during chemical reprogramming, Recommanded Product: 1-(3-((((2R,3S,4R,5R)-5-(4-Amino-7H-pyrrolo[2,3-d]pyrimidin-7-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl)(isopropyl)amino)propyl)-3-(4-(tert-butyl)phenyl)urea, the publication is Cell (Cambridge, MA, United States) (2015), 163(7), 1678-1691, database is CAplus and MEDLINE.

Somatic cells can be reprogrammed into pluripotent stem cells (PSCs) by using pure chems., providing a different paradigm to study somatic reprogramming. However, the cell fate dynamics and mol. events that occur during the chem. reprogramming process remain unclear. Here, the authors show that the chem. reprogramming process requires the early formation of extra-embryonic endoderm (XEN)-like cells and a late transition from XEN-like cells to chem.-induced (Ci)PSCs, a unique route that fundamentally differs from the pathway of transcription factor-induced reprogramming. Moreover, precise manipulation of the cell fate transition in a step-wise manner through the XEN-like state allowed the authors to identify small-mol. boosters and establish a robust chem. reprogramming system with a yield up to 1000-fold greater than that of the previously reported protocol. These findings demonstrate that chem. reprogramming is a promising approach to manipulate cell fates.

Li, Zhanchao published the artcilePreparation and characterization of two wood vinegars obtained from hull of spina date seed and shell of peanut, Recommanded Product: 3-Hydroxydihydrofuran-2(3H)-one, the publication is Chemical Research in Chinese Universities (2017), 33(3), 348-353, database is CAplus.

Two new kind of wood vinegars(WVs) from the hull of spina date seed(HSDS) and the shell of peanut(PS) were prepared 32 Major components in the two kind of WVs were identified and determined by gas chromato-graph-mass spectrometery. The total phenolic content was determined and the antioxidant activity of the WV was measured. The total phenolic contents of PSWV and HSDSWV were 75.9 and 98.1 mg/L, resp., when they were expressed as catechol equivalent In 1,1-diphenyl-2-picrylhydrazyl assay, free radical scavenging activity of HSDSWV was also superior than that of PSWV. In addition, the antioxidant activities of the two kind of WVs exhi-bited a good pos. correlation with total phenolic content, and the linear correlation coefficients ranged from 0.9594 to 0.9970. The two kind of WVs could be used in the fields of food and medicine due to their powerful anti-oxidant activities.

Li, Zhanchao published the artcileCharacterization of Five Kinds of Wood Vinegar Obtained from Agricultural and Forestry Wastes and Identification of Major Antioxidants in Wood Vinegar, Product Details of C4H6O3, the publication is Chemical Research in Chinese Universities (2019), 35(1), 12-20, database is CAplus.

Wood vinegar(WV) has a powerful antioxidant activity, but it is unclear which components are responsi-ble for the antioxidant activity. In the present study, the double-column retention index qual. method was used for the identification of the major components in five kinds of WV. And the major antioxidants of wood vinegar were accurately identified with the aid of Pearson product-moment correlation coefficients and authentic standard samples. Our results demonstrate that phenolic compounds are mainly responsible for the powerful antioxidant activity. 2,6-Dimethoxyphenol is the most powerful antioxidant in WV. 2-Methoxyphenol and 3-methyl-1,2-cyclopentane-dione also have an important influence on the antioxidant activity of WV. Our results suggest that the contents of 2-methoxyphenol, 2,6-dimethoxyphenol and 3-methyl-1,2-cyclopentanedione should act as the criteria for evaluating the antioxidant activity of WV. Our work will provide useful information for WV’s application in the fields of food and medicine as antioxidants.
