Enzymatic hydrolysis and auto-isomerization during beta-glucosidase treatment improve the aroma of instant white tea infusion

The aroma changes in instant white tea resulting from beta-glucosidase treatment was investigated by quantitative descriptive analysis (QDA), gas chromatography-mass spectrometry (GC-MS), odour activity value analysis (OAV), aroma reconstruction and omission tests. The grassy, floral and sweet notes increased significantly (P < 0.05), and the roasted note decreased significantly (P < 0.05) upon beta-glucosidase treatment. Quantitative analysis showed that the concentrations of benzaldehyde, benzeneacetaldehyde, (Z)-3-hexen-1-ol, linalool, phenylethyl alcohol, cis-linalool oxide, trans-linalool oxide, hexanol, hotrienol and (E)-2-hexen-1-ol increased significantly (P < 0.05) after treatment; however, (Z)-3-hexen-1-ol isomerized to (E)-2-hexen-1-ol. OAV analysis, aroma reconstruction and the omission test showed that the grassy, floral and sweet notes increased as the (Z)-3-hexen-1-ol, cis/trans-linalool oxide and benzeneacetaldehyde increased, whereas the roasted note declined under the same conditions. The enzymatic hydrolysis of glycosidic precursors and the auto-isomerization of volatile compounds provide new information for understanding how beta-glucosidase treatment improves the aroma of tea products.

Applications of emerging botanical hydrocolloids for edible films: A review

In recent years, many studies have been conducted on the production of edible films from emerging gums, which are mostly made from botanical sources. However, each one interacts differently with the film compounds, producing films with different properties that may improve or hinder their utilization in food packaging. Therefore, the aim of this review was to investigate and compare the physical, mechanical, thermal and structural properties of edible films produced with these emerging gums. The results of this review showed that it is possible to produce edible films with desirable physical, mechanical and thermal properties by optimizing the amounts and type of compounds in film formulations such as plasticizers, nanoparticles, lipid compounds, crosslinkers and combination of gums with other biopolymers. The future trends of this research include the deepening of knowledge to understand the molecular structures of emerging gums and to address the shortcomings of films based on these gums for their industrial-scale application in food packaging.

The relationship between alcohol and cannabis use with nonsuicidal self-injury among adolescent inpatients: Examining the 90 days prior to psychiatric hospitalization

Background: This study examined the trajectories of alcohol use, cannabis use, suicide planning (SP), and non-suicidal self-injury (NSSI) prior to hospitalization and examined the role of alcohol and cannabis use, independently and jointly, in predicting NSSI on a daily level and over time. Methods: Participants included 71 adolescents hospitalized for suicide risk (75% female; 25% male; M-age = 15.79). All participants drank alcohol at least once in the prior 90-days. We conducted mixed effect models to assess the trajectories of alcohol use, cannabis use, and NSSI over the 90-days prior hospitalization. To test the effect of SP, alcohol use, and cannabis use on NSSI, we conducted logistic random effect models, while controlling for demographics. Results: SP (OR = 4.47, p < 0.001) and suicide ideation (SI) (OR = 10.09, p < 0.001) significantly increased the odds of engaging in NSSI. Neither cannabis nor alcohol use independently predicted the odds of engaging in NSSI, however, the co-occurrence of alcohol and cannabis use increased the odds of engaging in NSSI on a given day (OR = 30.5, p < 0.05). Conclusions: Study findings extend current knowledge about the longitudinal and day-to-day relationships between alcohol and cannabis use and NSSI. Results underscore the importance of developing interventions that address polysubstance use among suicidal adolescents engaging in NSSI.

Determination and utilization of optimal diesel/n-butanol/biogas derivation for small utility dual fuel diesel engine

Aggregating pollution along with exhausting fossil fuels throughout the world has enforced the inventors to explore for an alternative fuel that can be utilized in diesel engines. Presently, investigators and professionals have originated that biodiesel in association with higher alcohols and gaseous fuel can be an alternative for the current circumstances. Anterior examinations have rendered that biodiesel and higher alcohol along with gaseous fuels can support in upgrading the performance and denigrating detrimental exhaust emanations in a diesel engine. This research aimed to investigate the impacts of engine load, n-butanol concentration, and biogas quantity on emissions and performance characteristics of a small utility compression ignition engine. The different engine load (20-100% of brake power), n-butanol concentration (0-20%) and biogas flow rate (0.5-2 kg/h) were used as input variables. The multi-criteria decision analysis based on response surface method techniques was employed to find the optimal values of engine working conditions fuelled with diesel/n-butanol/biogas fuel blends. In the optimization process, five objective functions (BTE, NOX, CO, UHC, and soot) were considered to be optimized based on the defined criteria. The addition of n-butanol in diesel has shown a favourable impact on biogas operated dual-fuel engine in terms of performance and emissions characteristics. The approach of desirability was applied to obtain the best operating conditions of the engine. The optimum value of engine load, n-butanol concentration, and biogas flow rate were found as 78.89%, 20%, and 1.37 kg/h, respectively. At this condition, the optimal value of BTE, UHC, CO, NOX, and smoke emissions were found to be 19.19%, 0.36g/kWh, 0.04%, 14.51g/kWh, and 22.32%, respectively. A high desirability value of 0.77 was obtained for the suggested condition, showing the efficiency of the derived models for response parameters.

Changes in aroma components and potential Maillard reaction products during the stir-frying of pork slices

Stir-fried pork slices are kinds of traditional pork processing products in China, which are usually cooked at high temperature with different seasonings. Because of their special quality and flavor, these products gain consumers’ preference. However, there are few studies on their physicochemical properties, aroma composition and safety. In this study, the changes in basic components, aroma components and potentially hazardous substances during the stir-frying of pork slices were determined. The effects of the different ratios of fat meat to lean meat and vinegar on these indicators were evaluated, and the formation of potential Maillard reaction products was also analyzed. The results indicated that water content, chrominance values of L* and b* exhibited decreasing trends; a* value displayed a trend of decline first and then rising, while the fat content showed a rising trend during the processing. Appropriate stir-frying can promote the formation of aldehydes, while the content of acids, ketones, and terpenes decreased during processing. The change of alcohols has no obvious rule. Some sulfur compounds not found in raw meat were also detected. Different ratios of fat meat and lean meat changed the kinds of aroma components, while vinegar altered the types and their contents. Besides, the contents of acrylamide and 5-HMF changed significantly, and that of benzo(a)pyrene remained at a low level. The addition of vinegar can enhance the amount of acrylamide and 5-HMF but has no obvious effect on benzo(a)pyrene. Besides, 8 kinds of Maillard reaction products (acrylamide, 5-HMF, benzo(a)pyrene, 5-methylfurfural, pyrazine, 4-methylimidazole, pyrraline, and 5- hydroxymethyl – 2-furancarboxylic acid) were determined, and some of them were harmful to product quality and human health. The results showed that the processing time of pork slices should be controlled within 60 min.

Folate, alcohol, ADH1B and ALDH2 and colorectal cancer risk

Objective: There is limited evidence on the interaction by alcohol dehydrogenase 2 (ADH1B) (rs1229984) and aldehyde dehydrogenase 2 (ALDH2) (rs671) regarding the associations of alcohol and a methyl diet (low folate and high alcohol intake) with cancer risk, partly because of rare polymorphisms in Western populations. Design: In a case-control study, we estimated the ORs and 95 % CIs to evaluate the associations of ADH1B and ALDH2 genotypes with colorectal cancer (CRC) and the joint association between methyl diets and ADH1B and ALDH2 polymorphisms with CRC risk using logistic regression models. Setting: A hospital-based case-control study. Participants: In total, 1001 CRC cases and 899 cancer-free controls admitted to two university hospitals. Results: We found that alcohol intake increased the risk of CRC; OR (95 % CI) was 2 center dot 02 (1 center dot 41, 2 center dot 87) for >= 60 g/d drinkers compared with non-drinkers (P (trend) < 0 center dot 001). The associations for two polymorphisms with CRC were not statistically significant. However, we found a potential interaction of ALDH2 with methyl diets and CRC. We observed a 9 center dot 08-fold (95 % CI 1 center dot 93, 42 center dot 60) higher risk of CRC for low-methyl diets compared with high-methyl diets among individuals with an A allele of ALDH2, but the association was not apparent among those with ALDH2 GG (P (interaction) = 0 center dot 02). Conclusions: Our data support the evidence that gene-methyl diet interactions may be involved in CRC risk in East Asian populations, showing that a low-methyl diet increased the risk of CRC among individuals with an A allele of ALDH2.

Diastereo- and Enantioselective Ruthenium-Catalyzed C-C Coupling of 1-Arylpropynes and Alcohols: Alkynes as Chiral Allylmetal Precursors in Carbonyl anti-(alpha-Aryl)allylation

Highly tractable 1-aryl-1-propynes, which are readily accessible via Sonogashira coupling, serve as chiral allylmetal pronucleophiles in ruthenium-JOSIPHOS-catalyzed anti-diastereo-and enantioselective aldehyde (alpha-aryl)allylations with primary aliphatic or benzylic alcohol proelectrophiles. This method enables convergent construction of homoallylic sec-phenethyl alcohols bearing tertiary benzylic stereocenters. Both steric and electronic features of aryl sulfonic acid additives were shown to contribute to the efficiency with which a more selective and productive iodide-bound ruthenium catalyst is formed. As corroborated by isotopic labeling studies, a dual catalytic process is operative in which alkyne-to-allene isomerization is followed by allene-carbonyl reductive coupling via hydrogen auto-transfer. Crossover of ruthenium hydrides emanating from these two discrete catalytic events is observed. The utility of this method is illustrated by conversion of selected reaction products to the corresponding phenethylamines and the first total syntheses of the neolignan natural products (-)-crataegusanoids A-D.

Chemically building interpenetrating polymeric networks of Bi-crosslinked hydrogel macromolecules for membrane supercapacitors

Macromolecular polymer hydrogels used in flexible supercapacitors and batteries have attracted extensive attention in recent years. In this paper, we use a simple polymer interpenetrating technology involving covalent cross-linking and non-covalent cross-linking aspects based on polyvinyl alcohol and carboxylated chitosan to prepare a flexible polymer hydrogel membrane for supercapacitor. The obtained hydrogel membrane has good flexibility and high ionic conductivity of 2.561 x 10(-2) s.cm(-1). The hydrogel electrode membrane prepared by in-situ polymerization of aniline exhibits an area specific capacitance of 580 mF.cm(-2) at a current density of 0.5 mA.cm(-2). And the symmetric all-gel-state supercapacitor with hydrogel membrane as the gel electrolyte shows a high specific capacitance of 325 mF.cm(-2) at 1.0 mA.cm(-2). We believe that this hydrogel film has considerable application prospects in flexible wearable electronic devices.

Fun/intoxication pre-drinking motives lead indirectly to more alcohol-related consequences via increased alcohol consumption on a given night

Introduction: Pre-drinking increases alcohol use on drinking nights, which is associated with various adverse alcohol-related consequences but what motivates people to do so, i.e. the role of pre-drinking motives (PDM) in this link, is unclear. The current study examined a) the association of three PDM factors (fun/intoxication, facilitation, and conviviality) with average night-level alcohol use, b) whether PDM are associated with adverse alcohol-related consequences (hangover, drunk driving, blackout, risky sex, injury, and fights) and c) whether PDM mediates the link between night-level alcohol use and negative consequences. Methods: A sample of 204 young adult nightlife goers (48.8% males, M age = 19 SD = 2.4) from Switzerland reported PDM at baseline, and subsequently participated in a 2-month event-level study. Regressions models assessed direct and mediated associations. Results: Fun/intoxication PDM predicted alcohol use in subsequent drinking nights (11.3 nights per participant on average), but not the two other PDM. No direct link between PDM and consequences was found. However, fun/intoxication PDM lead indirectly to more adverse consequences through higher alcohol use. Conclusion: This study shows that predominantly ‘fun/intoxication’ predrinkers are at increased risk for alcohol consumption and consequences, but not those who predrink for conviviality or facilitation motives. The outcomes thus suggest the importance of specific PDM in preventing alcohol use for instance by tailoring interventions based on individuals’ PDM in order to curb drinking and its associated consequences among young adults on weekend nights out.
