Effects of beverage alcohol taxes and prices on drinking: a meta-analysis of 1003 estimates from 112 studies

Aims: We conducted a systematic review of studies examining relationships between measures of beverage alcohol tax or price levels and alcohol sales or self-reported drinking. A total of 112 studies of alcohol tax or price effects were found, containing 1003 estimates of the tax/price–consumption relationship. Design: Studies included analyses of alternative outcome measures, varying subgroups of the population, several statistical models, and using different units of analysis. Multiple estimates were coded from each study, along with numerous study characteristics. Using reported estimates, standard errors, t-ratios, sample sizes and other statistics, we calculated the partial correlation for the relationship between alcohol price or tax and sales or drinking measures for each major model or subgroup reported within each study. Random-effects models were used to combine studies for inverse variance weighted overall estimates of the magnitude and significance of the relationship between alcohol tax/price and drinking. Findings: Simple means of reported elasticities are -0.46 for beer, -0.69 for wine and -0.80 for spirits. Meta-analytical results document the highly significant relationships (P < 0.001) between alcohol tax or price measures and indices of sales or consumption of alcohol (aggregate-level r = -0.17 for beer, -0.30 for wine, -0.29 for spirits and -0.44 for total alcohol). Price/tax also affects heavy drinking significantly (mean reported elasticity = -0.28, individual-level r = -0.01, P < 0.01), but the magnitude of effect is smaller than effects on overall drinking. Conclusions: A large literature establishes that beverage alcohol prices and taxes are related inversely to drinking. Effects are large compared to other prevention policies and programs. Public policies that raise prices of alcohol are an effective means to reduce drinking.

Optimisation of the extraction and processing conditions of chamomile (Matricaria chamomilla L.) for incorporation into a beverage

The total phenols, apigenin 7-glucoside, turbidity and colour of extracts from dried chamomile flowers were studied with a view to develop chamomile extracts with potential anti-inflammatory properties for incorporation into beverages. The extraction of all constituents followed pseudo first-order kinetics. In general, the rate constant (k) increased as the temperature increased from 57 to 100 °C. The turbidity only increased significantly between 90 and 100 °C. Therefore, aqueous chamomile extracts had maximum total phenol concentration and minimum turbidity when extracted at 90 °C for 20 min. The effect of drying conditions on chamomile extracted using these conditions was determined. A significant reduction in phenol concentration, from 19.7 ± 0.5 mg/g GAE in fresh chamomile to 13 ± 1 mg/g GAE, was found only in the plant material oven-dried at 80 °C (p ⩽ 0.05). The biggest colour change was between fresh chamomile and that oven-dried at 80 °C, followed by samples air-dried. There was no significant difference in colour of material freeze-dried and oven-dried at 40 °C.

Natural food and beverage flavour enhancers

Flavour enhancers are of great importance to the food industry and the consumer, in terms of achieving strong, balanced and preferred product flavour. The understanding and use of flavour enhancers can help to avoid excessive use of individual ingredients such as salt or specific character impact flavours. This chapter first discusses savoury flavour enhancement through the use of ingredients rich in amino acids and 5’nucleotides. It later includes the potential role of peptides and Maillard derived compounds. The role of volatile flavour compounds in the enhancement of salt and sweet taste is also discussed.

Determination of sorbate and benzoate in beverage samples by capillary electrophoresis - Optimization of the method with inspection of ionic mobilities

The aim of this study was to develop a fast capillary electrophoresis method for the determination of benzoate and sorbate ions in commercial beverages. In the method development the pH and constituents of the background electrolyte were selected using the effective mobility versus pH curves. As the high resolution obtained experimentally for sorbate and benzoate in the studies presented in the literature is not in agreement with that expected from the ionic mobility values published, a procedure to determine these values was carried out. The salicylate ion was used as the internal standard. The background electrolyte was composed of 25 mmol L(-1) tris(hydroxymethyl)aminomethane and 12.5 mmol L(-1) 2-hydroxyisobutyric acid, atpH 8.1.Separation was conducted in a fused-silica capillary(32 cm total length and 8.5 cm effective length, 50 mu m I.D.), with short-end injection configuration and direct UV detection at 200 nm for benzoate and salicylate and 254 nm for sorbate ions. The run time was only 28 s. A few figures of merit of the proposed method include: good linearity (R(2) > 0.999), limit of detection of 0.9 and 0.3 mg L(-1) for benzoate and sorbate, respectively, inter-day precision better than 2.7% (n =9) and recovery in the range 97.9-105%. Beverage samples were prepared by simple dilution with deionized water (1:11, v/v). Concentrations in the range of 197-401 mg L(-1) for benzoate and 28-144 mg L(-1) for sorbate were found in soft drinks and tea. (c) 2008 Elsevier B.V. All rights reserved.

The impact of price changes on volume sales of alcoholic beverages in Sweden, 2006-2013

We evaluate whether price elasticities on registered alcohol have changed in the last ten years in Sweden, in particular with regard to the investigation by Asplund et al (2007). We also investigate the fiscal effects of such changes. According to our estimates, price elasticities have increased, and these increases may have substantial effects on estimated changes in tax revenues when commodity tax rates are changed. In particular, commodity tax rates on spirits may have reached “Laffer territory” where tax increases may actually lower tax revenues.

Alcoholic women and men: a comparative study of social and familial aspects and outcome

Objetivos: A proporção de ocorrência de alcoolismo em homens e mulheres tem uma variação de 14:1 até 2:1, mostrando a necessidade de estudos específicos para a população feminina. O objetivo deste estudo foi analisar o perfil e a evolução de alcoolistas, segundo gênero e gravidade da dependência. Métodos: Realizou-se um estudo longitudinal retrospectivo de 114 homens e 57 mulheres alcoolistas (CID-10), inscritos no ambulatório da Faculdade de Medicina de Botucatu, no período de 1990-1994 e avaliados até julho de 1997. Utilizou-se um questionário semi-estruturado, e, para avaliação da gravidade do alcoolismo, o Short Alcohol Dependence Data. Resultados/Conclusões: Os principais resultados mostraram que a estrutura familiar estava comprometida com: relacionamento difícil para 55,6% das mulheres e 65,7% dos homens; violência familiar em 74,1% das mulheres e 61,1% dos homens. As mulheres iniciaram a ingestão mais tarde que os homens (p=0,01), em geral com seus cônjuges (p=0,00). Não houve diferença de evolução no tratamento entre os gêneros. Os principais fatores associados à melhor resposta ao tratamento, independentemente do sexo, foram: nível de gravidade de dependência do álcool (dependentes leves e moderados apresentaram 5,59 vezes mais chances de melhorar do que os dependentes graves); ser praticante de alguma religião (2,3 vezes mais chances de melhora do que os pacientes que não eram praticantes); e tempo de seguimento no programa, negativamente correlacionado a chances de melhora (0,68 vezes menos chances de melhora que aqueles que permaneceram por tempo menor em tratamento).

Effects of nutritional factors on growth of Lactobacillus fermentum mixed with Saccharomyces cerevisiae in alcoholic fermentation

The growth of Lactobacillus fermentum was studied in mixed culture with Saccharomyces cerevisiae during alcoholic fermentation of high test molasses (HTM). Yeast extract or a group of 17 amino acids caused a strong and fast decrease in yeast viability due to the strong increase of acidity produced by bacteria. Pure culture of Lactobacillus fermentum in dry sugar cane broth confirmed amino acids as the main nutrients needed to stimulate the growth of bacterial contaminant during alcoholic fermentation. The absence of L. fermentum growth was obtained when leucine: isoleucine or valine were not added to the medium. Phenylalanine, alanine, glutamic acid, cystine, proline, histidine, arginine, threonine, tryptophane, serine and methionine inhibited the bacterial growth at least in one of the cultures of L. fermentum tested.
