Alcohol consumption, harms and policy developments in sub-Saharan Africa: The case for stronger national and regional responses

Issues Sub-Saharan Africa (SSA) has long been characterised as a region with weak alcohol policies, high proportions of abstainers and heavy episodic drinkers (among drinkers), and as a target for market expansion by global alcohol producers. However, inter-regional analyses of these issues are seldom conducted. Approach Focusing mainly on the period 2000-2016, we compare alcohol consumption and harms, alcohol policy developments and alcohol industry activities over time and across the four sub-regions of SSA. Key Findings Per-capita consumption of alcohol and alcohol-related disease burden have increased in Central Africa but stabilised or reduced in other regions, although they are still high. Most countries have implemented tax policies, but they have seldom adopted other World Health Organization ‘best buys’ for cost-effective alcohol control policies. Countries range from having minimal alcohol controls to having total bans (e.g. some Muslim-majority countries); and some, such as Botswana, have attempted stringent tax policies to address alcohol harm. Alcohol producers have continued their aggressive marketing and policy interference activities, some of which have been highlighted and, in a few instances, resisted by civil society and public health advocates, particularly in southern Africa. Implications Increased government support and commitment are needed to be able to adopt and implement effective alcohol policies and respond to pressures from alcohol companies to which SSA remains a target market. Conclusion SSA needs effective alcohol control measures in order to reverse the trajectory of worsening alcohol harms observed in some countries and reinforce improvements in alcohol harms observed in others.

Analysis of volatile compound changes in fried shallot (Allium cepa L. var. aggregatum) oil at different frying temperatures by GC-MS, OAV, and multivariate analysis

Flavor is a key attribute of fried oil that shows a critical correlation with temperature. Therefore, selecting the appropriate temperature is important in preparing fried shallot oil (FSO). Volatile compounds from five different FSOs were identified and comparatively studied using gas chromatography-mass spectrometry (GC-MS) coupled with multivariate data analysis, including principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA). GC-MS results identified a total of 93 volatiles, among which aldehydes, alcohols, pyrazines, and sulfur-containing compounds were the major compounds. Eighteen compounds had odor active values (OAV) >1. Among the compounds, hexanal, (E)-2-heptenal, (E)-2-octenal, dipropyl disulfide, 2-ethyl-3,5-dimethylpyrazine, and 1-octen-3-ol were important to the overall aroma profile of FSOs. In the PCA model, all the detected FSOs were divided into three clusters, which were assigned as cluster A (FSO5), B (FSO4), and C (the rest FSOs). Multivariate data analyses revealed that nonanal, 2-ethyl-5-methylpyrazine, (E,E)-2,4-decadienal, (E)-2-heptenal, and hexanal contributed positively to the classification of different FSOs. GC-MS coupled with multivariate data analysis could be used as a convenient and efficient analytical method to classify raw materials.

Regular Elucidating the pH influence on pulsed electric fields-induced self-assembly of chitosan-zein-poly(vinyl alcohol)-polyethylene glycol nanostructured composites

Hypothesis: The high incompatibility of bio-based materials such as protein and polysaccharides require a series of modifications to develop stable microstructures effectively. By modifying the density and charge of surface residues, pulsed electric fields processing can improve inter/intramolecular interactions, compatibility, and microstructure of bio-based nanostructured composites. Experiment: In this work, the impact of pulsed electric fields at a specific energy of 60-700 kJ/kg (electric field strength = 1.6 kV/cm) on self-assembly of zein-chitosan-poly(vinyl alcohol)-polyethylene glycol composite dispersion was investigated at pH 4.0, 5.7, and 6.8. Findings: Superior complex coacervated matrices were assembled at pH 4.0 and 5.7 before and after pulsed electric fields treatment at a specific energy of 390-410 kJ/kg. The compact and homogenous behaviour was attributable to pulsed electric fields-induced alteration of functional group interactions in a pH-dependent manner. Irrespective of the pH, very high electric field intensity caused excessive system perturbation leading to severe fragmentation and poor development of coacervates. The crucial insights from this study reveal that the self-assembly behaviour and integration of biopolymer-based sys-tems possessing different local charges can be enhanced by optimising pulsed electric fields processing parameters and the properties of the colloidal systems such as the pH.

Compositional diversity and antioxidant properties of essential oils: Predictive models

The contribution of the chemical diversity of common essential oils to the antioxidant properties was investigated. Principal component analyses were performed to cluster essential oils with similar compositions and antioxidant properties, and to correlate their chemical profiles with their antioxidant properties. Moreover, mathematical models were developed for the prediction of antioxidant properties. Oregano, cinnamon, clove, pimento, thyme, and sage exhibited the highest antioxidant properties. When clustering based on the chemical profile, onion, cranberry, melissa, clove, cinnamon, and garlic oils were clustered into the same group. Correlation analysis showed concurrent abundance of some compounds in essential oils, for example, monoterpenes and alcohols contents increase simultaneously, and phenol-rich samples had higher sesquiterpenes content. The statistically significant predictive models were developed. These models revealed that the effects of monoterpenes, ketones and phenols concentration on antioxidant capacity were more significant. Phenols paired with esters and alcohols showed synergistic effects on hydrogen atom transfer-based ORAC value, whereas the opposite was true on single electron transfer-based IC50 when paired with monoterpenes and ketones. The developed predictive models are expected to provide the capability to predict the antioxidant properties of essential oils based on their chemical compositions and to identify combinations of oils that can act synergistically.

Evaluation of Lactococcus lactis subsp. lactis as protective culture for active packaging of non-fermented foods: Creamy mushroom soup and sliced cooked ham

An innovative edible coating, made from food grade polyvinyl alcohol (PVOH) and gelatin hydrolysates (HGel), was evaluated as a carrier of Lactococcus lactis acting as anti-listeria protective culture for refrigerated foods. The coating was applied on a compostable polylactic acid film surface and its anti-listeria activity was evaluated at 4 degrees C in a liquid culture medium and in solid agar, inoculated with Listeria monocytogenes. The best results were obtained in agar, exerting a bactericide effect, whereas in the liquid medium the coating had bacteriostatic behaviour. Furthermore, the active coating was applied to the surface of bags or separator liners made from polylactic acid. Its effectivity was evaluated with creamy mushroom soup (bags) and sliced cooked ham (separator liners) previously inoculated with L. monocytogenes and stored at 4 degrees C. Results showed that the coating was effective at inhibiting pathogen growth; however, it did not display a bactericide effect in the foods. In addition, L. lactis remained viable in all experiments conducted in this study. The acidification produced by L. lactis, because of the generation of organic acids, did not compromise the sensory properties of the sliced cooked ham after 16 days of refrigerated storage. In contrast, consumers perceived a mushroom soup acidification because of a greater decrease in pH than the sliced cooked ham. This study demonstrates that a food grade polyvinyl alcohol polymer blended with gelatin hydrolysates can be used as a carrier of protective cultures of L. lactis to increase the microbiological safety of refrigerated foods.

Hydrogen-free hydrogenation of furfural to furfuryl alcohol and 2-methyl-furan over Ni and Co-promoted Cu/gamma-Al2O3 catalysts

Catalytic transformation of furfural to furfuryl alcohol and 2-methylfuran without H-2 supply toward transfer hydrogenation process using 2-propanol as a H-2 source was systematically investigated over the bimetallic NiCuAl and CoCuAl catalysts in comparison with the monometallic CuAl, NiAl, and CoAl catalysts. The XRD analysis confirmed the generation of Ni-Cu and Co-Cu alloys after the reduction in presence of H-2. The interaction between Cu and Ni or Co resulted in a simplicity of the reduction behavior of Ni and Co species observed in H-2-TPR experiments. It was evident from pyridine adsorption FTIR analysis that the formation of bimetallic NiCu and Co-Cu alloys apparently improved the stronger Lewis acidic sites. The influences of reaction temperature and time were examined and optimized to maximize the yields of furfuryl alcohol and 2-methylfuran. The highest two major products yield and selectivity with lower by-products were obtained over the NiCuAl and CoCuAl catalysts compared with the CuAl and NiAl catalysts. The superior performance of the bimetallic catalysts was attributed to the stronger Lewis acidic centre on the catalyst surface. The CoCuAl catalyst was found to have lower catalyst deactivation and carbon deposition among the CuAl and NiCuAl catalysts under H-2-free atmosphere.

Promotion effect of La on oxygen vacancy formation over Zn-Cr based catalyst for isobutanol synthesis from syngas

A series of catalysts were designed and synthesized via doping lanthanum into ZnCr oxide to realize efficient synthesis of isobutanol from syngas. By applying a combination of characterizations (XRD, TEM, EPR, XPS and in situ FT-IR) and DFT calculations, the effects of lanthanum promoter on catalyst structure and catalytic performance were investigated. With the doping of lanthanum, ZnCrLax composite oxides with a novel catalyst structure were constructed, in which Zn atom at tetrahedron site was partly substituted by doping La atom. The presence of this structure enhanced the formation of more oxygen vacancy sites and further benefitted the CO activation. In addition, formate intermediate was easier to generate and exhibited superior stability over ZnCrLax surface thus leaded to remarkably promoted catalytic activity. The ZnCrLa0.05 catalyst achieved optimum total alcohols selectivity of 61%, and the fraction of isobutanol reached as high as 24.6% under CO conversion of 23%.

Tissue-specific transcriptome recovery on withdrawal from chronic alcohol exposure in zebrafish

Alcohol consumption can lead to a wide range of systemic disorders brought about by transcriptional changes. Recent studies have documented altered behavior and physiology in zebrafish exposed to alcohol. In this work, we have identified the changes in the zebrafish transcriptome in response to chronic alcohol exposure. We have further followed the extent of transcriptional recovery upon withdrawal from alcohol and found evidence of tissue-specific responses. Our results indicate a greater extent of recovery of the brain transcriptome compared to the liver. We identify two distinct classes of genes in response to withdrawal from alcohol exposure – those that recover their pre-alcohol expression profile versus those that retain altered expression even after the fish are removed from the alcohol environment. Finally, we have examined gender-specific responses to alcohol exposure in zebrafish and find evidence for distinct alcohol tolerance levels. Upon chronic alcohol exposure, a higher percentage of genes show perturbation in expression profile in males compared to females. Female fish also recover better with more genes regaining the control expression level upon withdrawal from alcohol. Overall, our work identifies genes and pathways perturbed by exposure to alcohol, and demonstrates the extent of gender- and tissue-specific transcriptional changes associated with chronic alcoholism and withdrawal.

Microalgal secondary metabolites: effect of climatic variables, seasons, and photocycles on the biogeneration of volatile organic compounds (VOCs)

Microalgae produce many metabolites with diversified structures that play important roles in their development. This work evaluated the effects of different climatic variables, seasons, and light/dark phases in the production of volatile organic compounds by Scenedesmus obliquus CPCC05, focusing on the simulation of climatic variables (average temperature, maximum light intensity, and light hours per day) of the extreme geographical positions of Brazil based on tropical Am, tropical Aw, and subtropical Cfa climates found in Joao Pessoa-PB, Rio Branco-AC, Boa Vista-RR, and Rio Grande-RS, in summer and winter seasons. For the best condition in this first step, the light/dark phases together with the residence time of the culture were evaluated. A total of 45 compounds were identified in all conditions studied. The main volatile groups found were hydrocarbons, aldehydes, ketones, alcohols, and terpenes identified in both geographic locations. Among these, hydrocarbons were the main biomarkers of the subtropical Cfa climate, while the ketone group was produced mainly in warmer climates, such as the Aw tropical climate. In the experiments of light/dark phases, a total of 34 compounds were identified. 2-Pentenol and decanal were only produced in the light phase, while 1-pentanol and 2-ethyl hexanol were only found in the dark phase. The main volatile compound found was 3-methylbutanol reaching a total area abundance of 14.10%. The major compounds detected during the cultures were originated and derived from the terpenoid pathways, fatty acids, and amino acid derivates.

Heating temperature dependence of molecular characteristics and biological response for biomass pyrolysis volatile-derived water-dissolved organic matter

The utilization of biomass pyrolysis volatile-derived water-dissolved organic matter (WOM, often called wood vinegar) determines sustainable recycling of biomass. Further, pyrolysis temperature significantly controls the cracking of biomass components, resulting in various molecular compositions and biological responses of WOM. Although it has been widely used in the agriculture, the relationship between molecular compositions and biological responses affected by heating temperature is still unclear. Here, it was observed that the WOM concentration increased with increasing temperatures and the pyrolysis of 1 g biomass can generate similar to WOM with 36.24 mg C. Moreover, with increasing pyrolysis temperatures, the generated WOM consisted of more phenols but fewer alcohols, furans, adds, and ketones, and demonstrated characteristics of higher aromaticity and lower m/z molecular weight. Due to the enhanced polarity, high temperatures promoted the solubility of WOM. Germination tests show that low pyrolysis temperatures-derived WOM (< 400 degrees C) with large-molecular-weight and low oxygen-containing (low O/C-wa) promoted plant growth, while high temperatures-derived WOM (> 400 degrees C) with small-molecular-weight and high oxygen-containing (high O/C-wa) inhibited growth. These results suggest that WOM can be separately collected at different pyrolysis temperatures to achieve sustainable recycling of pyrolysis volatile. (C) 2020 Elsevier B.V. All rights reserved.
