Antimicrobial Effects of Wine: Separating the Role of Polyphenols,pH, Ethanol,and Other Wine Components

Abstract: While the antimicrobial effectiveness of wine is well documented, relative contributions of the wine components to its antimicrobial activity is controversial. To separate the role of wine phenolics, ethanol, and pH from other wine constituents, the antimicrobial effects of intact wine were compared to that of phenols-stripped wine, dealcoholized wine, ethanol, and low pH applied separately and in combination, against 2 common foodborne pathogens, Salmonella enterica serovar Enteritidis and Escherichia coli. All samples were biochemically characterized with respect to their total phenolics and resveratrol content, antioxidant capacity, ethanol content, and pH. Antioxidative activity of the samples corresponded to their total phenolics content. Except for respective controls, pH and ethanol content were similar in all samples. The order of antibacterial activity of the samples was: intact wine > phenols-stripped wine > dealcoholized wine > combination of ethanol and low pH > low pH > ethanol. Separate application of ethanol or low pH showed negligible antibacterial activity while their combination showed synergistic effect. Antibacterial activity of the samples could not be related to their total phenolics and resveratrol content, antioxidant capacity, ethanol content, or pH. Our study indicates that antimicrobial activity of complex solutions such as intact wine cannot be exclusively attributed to its phenolic or nonphenolic constituents, nor can the antimicrobial activity of wine be predicted on the basis of its particular components.

Moisture sorption isotherms of green chilli

The adsorption and desorption equilibrium moisture contents of green chilli were determined experimentally in relative humidity range of 11‐97% and at the temperatures of 20, 30, 40 and 50°C. The experimental procedure used was a dynamic method with periodically recording of sample mass. The effect of temperature on adsorption and desorption isotherms was found significant. Hystereses were observed for entire range of relative humidity and hysteresis loops decreased with the increase of temperature. Nine sorption isotherm models were fitted the experimental data at the temperatures of 20, 30, 40 and 50 °C. The modified Smith equation was the best fitted equation to the experimental data for relative humidity range of 11‐97% for the adsorption and desorption isotherms of green chilli.

史前文化时期的酿酒(二)--谷芽酒的酿造及演进

我国的先民在仰韶时期(公元前5000年～公元前3000年)，就利用小口尖底瓮保温发酵酿制谷芽酒，并在该容器内澄清、饮用。到了大汶口时期(公元前4300年～公元前2400年)，酿酒有了较大发展，饮酒之风很盛行，出土了数量较多的大件酿酒发酵窖器——大口尖底陶尊及多姿多彩的酒具，表明了酒已具有礼仪功能。这时期谷芽酒的饮用方法已进步到用饮酒器饮用清酒了。酿酒技术及酒文化已由黄河下游扩展到淮河流域。     

Evaluation of the consistency of wine quality assessments from expert wine tasters

Background and Aims: The aim of this study was to assess the ability of experienced wine tasters to consistently assign quality scores to both red and white wines. Methods and Results: Wine quality scores were collected over a 15‐year period from 571 experienced wine tasters. Consistency was measured by correlating the scores given to duplicate presentations of wines, calculating the pooled variation in repeat scores and assessing their ability to allocate duplicate presentations of the same wine to the same quality category. Although the majority of tasters showed statistically significant consistency, their individual abilities varied considerably and, in general, their ability to consistently score one wine type was a poor predictor of their consistency in scoring the other. Tasters were better able to allocate duplicate presentations of red wines to the same category than white wines, and red wine consistency was improved by combining the scores of three assessors as is done in the Australian wine show system. Conclusions: The ability of experienced wine tasters to consistently rate wines for overall quality varied greatly between individuals, but was generally better for red wines than for whites. Consistency was improved by combining the scores from a small team of tasters. Significance of the Study: The study demonstrates the need to conduct replicate tastings when assessing wines for quality as adequate taster repeatability cannot be guaranteed. Furthermore, using the combined score of a small team of tasters generally results in more consistent quality assessments.
