Free fatty acids responsible for characteristic aroma in various sauced-ducks

To investigate the effects of various duck sources on the lipid oxidation and aroma flavor of sauced-ducks, Mallard (ML), Sheldrake (SD), Muscovy (MC), and Cherry-Valley (CV) ducks were used in sauced-duck processing. The results showed significantly different thiobarbituric acid reactive substances (TBARS) values of the four samples (SD 0.05), while the contents of unsaturated fatty acids (UFAs) were ML SD/CV > MC (p < 0.05). Altogether, 105 volatile flavor compounds were detected in sauced-ducks, including acids, alcohols, aldehydes, ketones, esters, hydrocarbons, furans, nitrogen compounds, and others. The volatile compounds were observed differentially composed in the four products, and nineteen potential characteristic biomarkers were explored. The correlation analysis indicated that the characteristic aroma flavor of sauced ducks were significantly associated with specific free fatty acids. These information are useful for learning aroma formation and meat selection and identification in duck products. If you¡¯re interested in learning more about 42142-52-9.

High-temperature oxidation of propanol isomers in the mixtures with N2O at high Ar dilution conditions

This work provides, for the first time, new information regarding the kinetics interaction between N2O and propyl alcohol isomers. To this end, the formation and consumption of atomic oxygen were measured behind the reflected shock waves using Atomic Resonance Absorption Spectroscopy (ARAS) technique for 1-10 ppm n- i- propanol + 10 ppm N2O + Ar mixtures, at 2-3 bar and over a wide temperature range of 1700-3200 K. The Konnov and POLIMI detailed combustion mechanisms were assessed against experimental data and also employed to study the main reactions influencing the oxidation dynamics of fuel mixtures under the investigated conditions. The study highlighted a certain difficulty by the models tested in predicting the formation of atomic oxygen at T < 2000 K. The rate of production and the sensitivity analysis was performed with the attempt to identify the most important reactions involved in the process oxidation for future kinetic model refinements.

Optimization of pretreatment and enzymatic hydrolysis conditions of tomato pomace for production of alcohols and esters by Kluyveromyces marxianus

Tomato pomace (TP) is generated as a natural by product in a significant amount in the tomato processing industry, and it is a good source of lignocelluloses to produce some high-value products from fermentable sugars (FS). The present study was performed to produce FS by using either ultrasound-assisted dilute acid (UADA) or heat-treated dilute acid (HTDA) pretreatments of TP followed by enzymatic hydrolysis (EH). When HTDA and UADA were compared in terms of FS (g/L) concentration, HTDA pretreatment generally produced more FS content than UADA. The optimum conditions for HTDA pretreatment were the application of 2.5% H2SO4, 10% (w/v) solution of TP, and heating at 121 degrees C for 6 min, which yielded 31 g/L FS concentration. Beside the optimized conditions for EH of HTDA, pretreated TP required 1.5% of enzyme concentration and 6 h of hydrolysis time. In conclusion, the most abundant volatile organic compounds (VOCs) produced by K. marxianus in final tomato pomace hydrolysate (TPH) were isoamyl alcohol, phenyl ethyl alcohol, ethyl acetate and phenyl ethyl acetate in a 5-L bioreactor. Nine descriptive sensory terms were developed to characterize fermented TPH. The rose and sweet floral aromas were defined as aroma characteristics for TPH fermented by K. marxianus.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 927-74-2, in my other articles. SDS of cas: 927-74-2.

Chromoselective Photocatalysis Enables Stereocomplementary Biocatalytic Pathways**

Controlling the selectivity of a chemical reaction with external stimuli is common in thermal processes, but rare in visible-light photocatalysis. Here we show that the redox potential of a carbon nitride photocatalyst (CN-OA-m) can be tuned by changing the irradiation wavelength to generate electron holes with different oxidation potentials. This tuning was the key to realizing photo-chemo-enzymatic cascades that give either the (S)- or the (R)-enantiomer of phenylethanol. In combination with an unspecific peroxygenase from Agrocybe aegerita, green light irradiation of CN-OA-m led to the enantioselective hydroxylation of ethylbenzene to (R)-1-phenylethanol (99 % ee). In contrast, blue light irradiation triggered the photocatalytic oxidation of ethylbenzene to acetophenone, which in turn was enantioselectively reduced with an alcohol dehydrogenase from Rhodococcus ruber to form (S)-1-phenylethanol (93 % ee).

Impacts of childhood adversity forms and drinker self-schema on undergraduate drinking behaviors and depression

Purpose: Drinking behaviors and depression are common and highly correlated behaviors in undergraduates. Child adversity and drinker self-schemas have been recognized as significant risk factors of drinking behaviors and depression. However, how the various child adversity forms differentially influence the formation of drinker self-schema and behaviors is underexplored. We aimed to determine whether drinker self-schema serves as a mechanism underlying the influence of child adversity forms on drinking frequency, drinking problems, and depressive symptoms. Methods: A cross-sectional, correlational study design with an anonymous, internet-based survey was conducted. Participants were 330 first- and second-year undergraduates enrolled in a four-year college/university as full–time students in Taiwan. Path analysis was performed to examine the direct and indirect effects (through drinker self-schema) of child adversity forms on drinking frequency, drinking problems, and depressive symptoms. Gender and friend’s alcohol use were the covariates. Results: Psychological abuse, psychological neglect, physical neglect, and household substance use were associated with drinker self-schema, which was associated with drinking frequency, drinking problems, and depressive symptoms. Physical abuse was associated with drinking frequency. Household substance use and parent(s) treated violently were associated with drinking problems. Psychological neglect and household mental illness were associated with depressive symptoms. Moreover, psychological abuse and psychological neglect had indirect effects on drinking frequency and drinking problems through drinker self-schema. Conclusions: Different forms of childhood adversity are differently associated with drinker self-schema, drinking behaviors, and depression. Drinker self-schema serves as an underlying mechanism linking psychological mal-treatments to drinking behaviors.

Techno-economical and energy analysis of sunflower oil biodiesel synthesis assisted with waste ginger leaves derived catalysts

The present study was carried out to investigate biodiesel production via transesterification of sunflower oil employing heterogeneous catalyst derived from indigenous ginger (Zingiber Officinale) leaves. It also aims to compare the techno-economy performance of the ginger-based catalysts in 3 different forms viz. calcinated (CGL), activated by KOH (KGL) and NaOH (NGL). The plant-based catalysts were characterised by Scanning electron microscopy (SEM), Brunauer-Emmett-Teller (BET) and Fourier transform infrared spectroscopy (FTIR). The parametric effects on the biodiesel production such as reaction time, methanol to oil ratio and catalyst loading were investigated. The experimental result shows that 1.6 wt % catalyst, 6:1 M ratio of alcohol to oil, 1 h 30 min of reaction time with a speed of 200 rpm gave the best results. It was found that the KGL obtained highest biodiesel yield of 93.83% under optimum conditions. Subsequently, the specific energy and energy productivity of KGL catalyst was found to be 1.2728, 26.1544 MJ/ kg and 0.0382 kg/MJ, respectively, per 1 L of biodiesel. Meanwhile, the renewable energy to nonrenewable energy ratio for CGL, KGL and NGL is found to be 3.17, 4.01 and 3.67, respectively. A higher sustainable renewable energy-yield ratio and overall economical profit cost ratio are preferable for the biodiesel production process. (c) 2020 Elsevier Ltd. All rights reserved.

Transesterification of parsley seed oil using a green catalyst: considering the optimization process and modeling

Y The production of bio-based diesel by using calcium oxide catalyst derived from waste material was investigated in this work as well as the influence of varying the process variables on the biodiesel yield. The optimisation of the process variables (ratio of alcohol-to-oil, temperature, and the amount of catalyst) for parsley biodiesel was achieved using RSM. The biodiesel yield of 92.19% was predicted from the data analysis as the optimum yield at optimum reaction conditions of 9.4:1, 59.31 degrees C, and 2.7 wt% for the molar ratio of alcohol: oil, temperature and catalyst amount respectively. The characterisation of the biodiesel was achieved with FTIR and GC-MS. Also, the fuel characteristics of biodiesel were within the specifications of the ASTM D6751.

Association between environmental exposure to cadmium and risk of suspected non-alcoholic fatty liver disease

Aim: We evaluated the associations between blood Cadmium (Cd) concentrations and risk of suspected NAFLD using nationally representative data from the Korea National Health and Nutrition Examination Survey (KNHANES) 2008-2013, 2016 and 2017. Methods: This cross-sectional study included 12,099 adults for the serum alanine aminotransferase (ALT) and hepatic steatosis index (HSI) analyses and 2,904 adults for the serum gamma-glutamyl transferase (GGT) and fatty liver index (FLI) analyses, without significant alcohol consumption. Blood Cd concentrations were measured by graphite furnace atomic absorption spectrometry. Data were analyzed using survey logistic regression models. Results: Odds ratios (ORs) of suspected NAFLD increased significantly per unit of natural log-transformed blood Cd concentration (OR [95% (CI)], for ALT, overall: 1.50 [1.34, 1.68], men: 1.64 [1.40, 2.10] and women: 1.29 [1.08, 1.47]; for GGT, overall: 1.77 [1.33, 2.35], men: 2.28 [1.53, 3.41] and women: 1.27 [0.82, 1.97]; for FLI, overall: 1.84 [1.32, 2.57], men: 1.91 [1.24, 2.94] and women: 1.58 [0.87, 2.86]; for HSI, overall: 1.19 [1.07, 1.32], men: 1.17 [1.01, 1.37] and women: 1.14 [0.99, 1.32]). The blood Cd concentrations associated with risk of suspected NAFLD were lower than those previously reported (for ALT, > 0.64 mg/L, for GGT, > 1.41 mg/L, for FLI, > 0.96 mg/L, and for HSI, > 1.41 mg/L). Conclusions: This study suggests that the reference level of blood Cd should probably be lower than the previously recommended value to prevent adverse health effects due to Cd exposure.

The carbon footprint of alternative jet fuels produced in Brazil: exploring different approaches

Although the potential of Alternative Jet Fuels (AJF) to reduce greenhouse gases (GHG) emissions has been widely reported upon in the literature, there are still discrepancies among the results. These may be due to the different GHG accounting methods, including those used by different Low-Carbon Policies (LCPs). To have a clearer understanding of the life cycle performance of AJF, the carbon footprint of ten pathways was estimated, comprising promising feedstocks – such as soybean, palm, sugarcane, sugarcane residues, forestry residues, used cooking oil, beef tallow, and steel off-gases – and ASTM-approved technologies: Hydroprocessed Fatty Acids, Alcohol-to-Jet, and Fischer-Tropsch. Six methodological approaches were used: the attributional and the consequential life cycle assessment, as well as guidelines for the four LCPs: Renovabio (Brazil), CORSIA (aviation sector), RFS (United States), and RED II (Europe). Soybean-based pathway (24 to 98.7 gCO(2e)/MJ) had the low to no potential for reducing GHG when compared to their fossil counterparts, mainly due to land use change. Of all food-based pathways, AJF produced from sugarcane performed the best (-10.4 to 43.7 gCO(2e)/MJ), especially when power surplus was credited. AJF from palm oil could present significant GHG reduction for palm expansion in degraded pasturelands. By contrast, Fischer-Tropsch of lignocellulosic residues showed the highest potential for reducing GHG (-95% to -130%). Different from food-based pathways, the potential GHG reduction of residues-based pathways converged within a narrower range (-130% to -50%), except when residual feedstocks have to be redirected from their current economic use. It could lead to GHG emissions higher than fossil fuel.

Distinct Whole-Body Movements in Response to Alcohol and Sexual Content in Alcohol Use Disorder

Background Spontaneous motor responses of approach and avoidance toward stimuli are important in characterizing psychopathological conditions, including alcohol use disorder (AUD). However, divergent results have been reported, possibly due to confounded parameters (e.g., using a symbolic vs. a sensorimotor task, implementation of approach-avoidance as a measure vs. a manipulation). Methods We studied whole-body/posturometric changes by using a sensorimotor measure relying on embodied cognition principles to assess forward (approach) and backward (avoidance) spontaneous leaning movements. Over a 12-second period, 51 male patients with AUD and 29 male control participants were instructed to stand still in response to both alcohol and sexual visual content. Patients with AUD were then divided into abstainers and relapsers, depending on their continuous abstinence at 2 weeks postdischarge (obtained via a telephone follow-up interview). The effects of the group, the stimulus type, the experimental period, and their interactions on the posturometric changes were tested using mixed Analyses of variance (ANOVAs), with a significance threshold set at 0.05. Results Contrary to our expectations, patients and controls did not show significant difference in their forward/backward micromovements while passively viewing alcohol or sexual content (p > 0.1). However, in line with our hypothesis, patients who relapsed several weeks following discharge from the rehabilitation program were significantly more reactive and more likely to lean back during the first seconds of viewing alcohol cues (p = 0.002). Further, relapsers were more likely to lean forward during exposure to sexual content than participants who remained abstinent (p < 0.001). Conclusions Among individuals with AUD, there are distinct pattern of spontaneous movements that differentiate abstainers and relapsers, findings that can be understood in light of existing data and theories on action tendencies.
