Non-Saccharomyces yeasts play an important role in greengage fermentation To obtain practical non-Saccharomyces yeasts for high-acid fermentation environments, and improve the flavor quality of fermented greengage beverage, four indigenous acid-tolerant non-Saccharomyces yeast strains were used to conduct greengage fermentation Hanseniaspora occidentalis, Pichia terricola, and Issatchenkia orientalis were competitively fermentable and significantly decreased the concentration of citric acid and malic acid. HS-SPME and GC-MS were used to analyze the aroma profiles, and results showed that H. occidentalis has potential to produce explicit fruity aroma, since the fermented beverages obtained more esters. Moreover, phenolic acids had the highest concentration among polyphenols of fermented greengage beverage. Comparatively, spontaneous fermentation produced higher levels of most polyphenols, whereas P. terricola treatment resulted predominantly in partial phenolic acids. Kendall coefficients indicated that procyanidins and glycosidic bound flavonols significantly pos. correlated with more than 30% volatiles. This study verified the biofunctions of non-Saccharomyces yeasts and applied their potential for flavor improvement in the production of high-acidity fermented fruit beverages.

Huang, Mingzheng published the artcileComparative characterization and sensory significance of volatile compounds in Rosa roxburghii Tratt fruit from five geographic locations in Guizhou, China, Recommanded Product: Benzyl acetate, the main research area is Rosa roxburghii Tratt fruit volatile compound sensory Guizhou China.

Rosa roxburghii Tratt (Chestnut rose) is native to China where it is cultivated for its strongly aromatic hips (pseudo fruits); locally known as cili. Increasing interest in cili for food and beverage products prompted an evaluation of its aroma compounds and the influence of geog. source. Accordingly, the volatile compounds in cili from five locations in Guizhou province were analyzed by headspace-solid-phase microextraction coupled with gas chromatog.-mass spectrometry. Sixty-seven volatile compounds were identified. Principal component anal. distinguished three sample groups by geog. source. The aroma of cili juice from each location was characterized by quant. descriptive anal. using six odor descriptors. Cili aroma was predominantly sweet/fruity, floral and green, but geog. source significantly influenced the intensity of the sweet/fruity and floral notes. Odor activity analyses indicated that 40 volatile compounds contribute appreciably to the aroma of cili. Of those compounds, only ten esters, two aldehydes, one alc. and one aromatic compound were common to all regional samples. Those findings extend the range of volatiles detected in cili. These results identify those that are present in odor active amounts and provide the first evidence of the impact of geog. source on the aroma and flavor of cili.

Feng, Dedang published the artcileComparison of volatile compounds between wild and cultivated roses, Category: esters-buliding-blocks, the main research area is volatile compound wild cultivated rose.

Rose (Rosa L.) is an economically important ornamental genus that has been cultivated for its scent for the perfume industry since antiquity. However, most modern roses have lost their fragrance during the later stages of the breeding process. Here, 59 species of Rosa, including 24 wild Rosa species, 20 Chinese old garden roses, and 15 modern roses, were examined by headspace solid-phase microextraction and gas chromatog.-mass spectrometry. Fifty-three volatile organic compounds (VOCs), including terpenoids, benzenoids/phenylpropanoids, and fatty acid derivatives, were detected with qual. and quant. analyses. Thirteen common components, including geraniol, citronellol, 2-phenylethanol, 3,5-dimethoxytoluene, 1,3,5-trimethoxybenzene, germacrene D, and cis-3-hexenyl acetate, were found. Furthermore, different wild species or cultivars showed different characteristic compounds 3,5-Dimethoxytoluene and 1,3,5-trimethoxybenzene were the main compounds in Rosa odorata and Rosa chinensis, which are the original parents of modern roses. 2-Phenylethanol, citronellol, and geraniol were the main aromatic compounds in Rosa damascene and Rosa centifolia. Me salicylate, eugenol, Me eugenol, and benzyl acetate were lost during domestication and breeding of wild Rosa species to Chinese old garden roses and then to modern cultivars. Geranyl acetate, neryl acetate, and dihydrob-ionol were gained during this time and showed higher amounts across the rose breeding process. Natural and breeding selection may have caused volatile compound gains and losses. These findings provide a platform for mining scent-related genes and for breeding improved ornamental plants with enhanced flower characteristics to develop new essential oil-producing plants.

Bahena-Garrido, Sharon Marie published the artcileThe potential aroma and flavor compounds in Vitis sp. cv. Koshu and V. vinifera L. cv. Chardonnay under different environmental conditions, SDS of cas: 140-11-4, the main research area is Vitis aroma flavor abscisic hydroxycinnamic acid environment; disease resistance; flavor precursors; light; phytohormone; secondary metabolites; stress response.

BACKGROUND : Koshu, a hybrid of Vitis vinifera L. and V. davidii Foex, is the most popular indigenous cultivar for wine production in Japan. However, little is known about the potential aroma compounds it contains and how environmental factors affect these. In this study, we obtained comprehensive profiles of the volatile (both glycosidically bound and free) and phenolic compounds that occur in koshu berries, and compared these with similar profiles for V. vinifera cv. chardonnay. We then compared the response of these two cultivars to bunch shading and the ripening-related phytohormone abscisic acid (ABA). RESULTS : Koshu berries contained significantly higher concentrations of phenolic compounds, such as hydroxycinnamic acid derivatives, and some volatile phenols, such as 4-vinyl guaiacol and eugenol, than chardonnay berries, which are thought to contribute to the characteristics of koshu wine. In addition, koshu berries had a distinctly different terpenoid composition from chardonnay berries. Shading reduced the concentration of norisoprenoid in both cultivars, as well as several phenolic compounds, particularly their volatile derivatives in koshu berries. The exogenous application of ABA induced ripening and increased the concentrations of lipid derivatives, such as hexanol, octanol, 1-nonanol, and 1-octen-3-ol. Multivariate and discriminant analyses showed that the potential aroma and flavor compounds in the berries could be discriminated clearly based on cultivar and environmental cues, such as light exposure. CONCLUSION : The unique secondary metabolite profiles of koshu and their different responses to environmental factors could be valuable for developing various types of koshu wines and new cultivars with improved quality and cultural characteristics. © 2018 Society of Chem.

Pavlovic, Radmila published the artcileEffectiveness of different analytical methods for the characterization of propolis: a case of study in Northern Italy, HPLC of Formula: 140-11-4, the main research area is propolis phenol flavone radical scavenger HPLC GC MS; HPLC–Q-Exactive-Orbitrap®–MS analysis; phenolic glycerides; poplar; propolis.

Propolis is used as folk medicine due to its spectrum of alleged biol. and pharmaceutical properties and it is a complex matrix not still totally characterized. Two batches of propolis coming from two different environments (plains of Po Valley and the hilly Ligurian-Piedmont Apennines) of Northern Italy were characterized using different anal. methods: Spectrophotometric anal. of phenols, flavones and flavonols, and DPPH radical scavenging activity, HPLC, NMR, HSPME and GC-MS and HPLC-MS Orbitrap. Balsam and moisture content were also considered. No statistical differences were found at the spectrophotometric anal.; balsam content did not vary significantly. The most interesting findings were in the VOCs composition, with the Po Valley samples containing compounds of the resins from leaf buds of Populus nigra L. The hills (Appennines) samples were indeed characterize by the presence of phenolic glycerides already found in mountain environments. HPLC-Q-Exactive-Orbitrap-MS anal. is crucial in appropriate recognition of evaluate number of metabolites, but also NMR itself could give more detailed information especially when isomeric compounds should be identified. It is necessary a standardized evaluation to protect and valorize this production and more research on propolis characterization using different anal. techniques.

Yang, Yanqin published the artcileAroma dynamic characteristics during the process of variable-temperature final firing of Congou black tea by electronic nose and comprehensive two-dimensional gas chromatography coupled to time-of-flight mass spectrometry, COA of Formula: C9H10O2, the main research area is congou black tea faint scent floral aroma; Comprehensive two-dimensional gas chromatography coupled to time-of-flight mass spectrometry; Congou black tea; Electronic nose; Final firing; Multivariate statistical analysis.

The drying technol. is crucial to the quality of Congou black tea. In this study, the aroma dynamic characteristics during the variable-temperature final firing of Congou black tea was investigated by electronic nose (e-nose) and comprehensive two-dimensional gas chromatog. coupled to time-of-flight mass spectrometry (GC x GC-TOFMS). Varying drying temperatures and time obtained distinctly different types of aroma characteristics such as faint scent, floral aroma, and sweet fragrance. GC x GC-TOFMS identified a total of 243 volatile compounds Clear discrimination among different variable-temperature final firing samples was achieved by using partial least squares discriminant anal. (R2Y = 0.95, Q2 = 0.727). Based on a dual criterion of variable importance in the projection value (VIP > 1.0) and one-way ANOVA (p < 0.05), ninety-one specific volatile biomarkers were identified, including 2,6-dimethyl-2,6-octadiene and 2,5-diethylpyrazine with VIP > 1.5. In addition, for the overall odor perception, e-nose was able to distinguish the subtle difference during the variable-temperature final firing process.

Lalikoglu, Melisa published the artcileThe Synthesis of Benzyl Acetate as a Fragrance and Flavoring Agent with Green Solvents., Computed Properties of 140-11-4, the main research area is .

Benzyl acetate, which has a crucial role in the industry as a flavor and fragrance component, is important for human health to be obtained with a green and clean process. For this purpose, the esterification reaction of acetic acid (AA) and benzyl alcohol (BA) was investigated using five different ionic liquids (ILs) as catalysts. 1-Ethyl-3-methylimidazolium hydrogen sulfate, [EMIM] [HSO4], 1-Ethyl-3-methylimidazolium tetrafluoroborate [EMIM] [BF4], 1-methyl-3-octylimidazolium tetrafluoroborate [OMIM] [BF4], 1-ethyl-3-methylimidazolium bis [(trifluoromethyl)sulfonyl] imide [EMIM] [NTf2], and 1,3-diethylimidazolium bis [(trifluoromethyl)sulfonyl] imide [DEIM] [NTf2] were used as catalysts. The best catalytic performance was obtained with 1-Ethyl-3-methylimidazolium hydrogen sulfate, [EMIM] [HSO4]. The influence of different anions and cations in the IL’s structure, the reaction conditions such as initial acid/alcohol ratio, the catalyst amount, the reaction temperature, and the time on conversion were observed. The Box-Behnken experimental design of response surface methodology was applied to estimate the relationship between acid conversion (%) and reaction parameters. According to the model, in all esterification experiments carried out at 110°C, the optimum conditions for maximum conversion were AA:BA molar ratio of 1:1, IL molar ratio of 0.66, and reaction time 4 hours. Under these conditions, 90.34% acid conversion was achieved. [EMIM] [HSO4] can be used for up to three cycles with minimal loss in activity.

Gnimavo, Ronald Sètondji published the artcileAssociated factors study into the belated screening for leprosy in Benin., Safety of Benzyl acetate, the main research area is .

INTRODUCTION: In the absence of early treatment, leprosy, a neglected tropical disease, due to Mycobacterium leprae or Hansen Bacillus, causes irreversible grade 2 disability (G2D) numerous factors related to the individual, the community and the health care system are believed to be responsible for its late detection and management. This study aims to investigate the factors associated with belated screening for leprosy in Benin. METHODS: This was a cross-sectional, descriptive, and analytical study conducted from January 1 to June 31, 2019, involving all patients and staff in leprosy treatment centers and public peripheral level health structures in Benin. The dependent variable of the study was the presence or not of G2D, reflecting late or early screening. We used a logistic regression model, at the 5% threshold, to find the factors associated with late leprosy screening. The fit of the final model was assessed with the Hosmer-Lemeshow test. RESULTS: A number of 254 leprosy patients were included with a mean age of 48.24 ± 18.37 years. There was a male dominance with a sex ratio of 1.23 (140/114). The proportion of cases with G2D was 58.27%. Associated factors with its belated screening in Benin were (OR; 95%CI; p) the fear of stigma related to leprosy (8.11; 3.3-19.94; <0.001), multiple visits to traditional healers (5.20; 2.73-9.89; <0.001) and multiple visits to hospital practitioners (3.82; 2.01-7.27; <0.001). The unawareness of leprosy by 82.69% of the health workers so as the permanent decrease in material and financial resources allocated to leprosy control were identified as factors in link with the health system that helps explain this late detection. CONCLUSION: This study shows the need to implement strategies in the control programs to strengthen the diagnostic abilities of health workers, to improve the level of knowledge of the population on the early signs and symptoms of leprosy, to reduce stigmatization and to ban all forms of discrimination against leprosy patients.

Xu, Lu published the artcileWidespread receptor-driven modulation in peripheral olfactory coding, SDS of cas: 140-11-4, the main research area is .

Olfactory responses to single odors have been well characterized but in reality we are continually presented with complex mixtures of odors. We performed high-throughput anal. of single-cell responses to odor blends using Swept Confocally Aligned Planar Excitation (SCAPE) microscopy of intact mouse olfactory epithelium, imaging ∼10,000 olfactory sensory neurons in parallel. In large numbers of responding cells, mixtures of odors did not elicit a simple sum of the responses to individual components of the blend. Instead, many neurons exhibited either antagonism or enhancement of their response in the presence of another odor. All eight odors tested acted as both agonists and antagonists at different receptors. We propose that this peripheral modulation of responses increases the capacity of the olfactory system to distinguish complex odor mixtures

Sedney, Cara L published the artcileTraumatic spinal cord injury in West Virginia: Disparities by insurance and discharge disposition from an acute care hospital., Synthetic Route of 140-11-4, the main research area is Health outcomes; Insurance disparities; Rehabilitation; Spinal cord injury; West Virginia.

Context: Medicaid has been linked to worse outcomes in a variety of diagnoses such as lung cancer, uterine cancer, and cardiac valve procedures. It has furthermore been linked to the reduced health-related quality of life outcomes after traumatic injuries when compared to other insurance groups. In spinal cord injury (SCI), the care provided in the subacute setting may vary based upon payor status, which may have implications on outcomes and cost of care.Design: A retrospective review utilizing the institutional trauma databank was performed for all adult patients with spinal cord injury since 2009. Pediatric patients were excluded. Insurance type, race, length of stay, discharge status (alive/dead), discharge disposition, injury severity score (ISS), and hospital charges billed were recorded.Results: Two hundred patients were identified. Overall 27.5% of patients with SCI during the period of our review were Medicaid beneficiaries. ISS was similar between Medicaid and non-Medicaid patients, but the Medicaid beneficiaries were younger (37 vs 50 years of age; P < .001). Medicaid beneficiaries had a significantly longer length of stay (20.9 days; P < .001) when compared to all other patients. They furthermore were more likely to be discharged home or to a skilled nursing facility rather than an acute rehabilitation center. Inpatient charges billed for Medicaid beneficiaries were significantly higher than those of non-Medicaid patients (203,264 USD vs 140,114 USD; P = .015), likely reflecting the increased length of stay while awaiting appropriate disposition.Conclusion: Medicaid patients with SCI in West Virginia had a longer hospital stay, higher charges billed, and were more likely to be discharged home or to a skilled nursing facility rather than an acute rehabilitation center, when compared to non-Medicaid patients. The lack of availability of rehabilitation facilities for Medicaid beneficiaries likely explains this difference.
