冬季,湘泉酒部分窖池出酒率降低,平均出酒率只有28%,调查发现,冬季出池酒酷温度在22℃,同酒率正常,在15℃左右时,出酒率很低,经对窖池发酵情况跟踪检测发现,顶火温度对出酒率影响很大,顶火温度高于30摄氏度,出酒率最高,比顶火温度25-30℃的高4.7%,比顶火温度25摄氏度以下的高16.5%,造成发酵不升温的原因主要有地温下降,微生物数量特别是酵母数量不够及窖帽太高所致,将入池温度提高到20-23摄氏度,大曲用量提高到25%,添加700g安琪活性干酵母,降低窖帽不超过50cm,加厚封窖泥至15cm以上进行试验,结果表明,添加活性干酵母出酒率最高,较其他方法高5%-7%。 相似文献

沙棘果粉碎后分离出的果汁需加果胶酶进行澄清,澄清温度20-25℃,pH4.2~4.5,果胶酶加量为0.3%~0.4%。麦汁冷却后,满罐时将沙棘汁定量泵入发酵罐,添加酵母进行发酵。生产中应注意:①沙棘汁含糖量较高,实际生产中原麦汁浓度可略低一些;②沙棘加工过程应切实做好防氧化并保持沙棘果汁无菌状态;③沙棘汁中果胶物质含量较高,若处理不好将对成品酒非生物稳定性产生很大影响;④沙棘果汁添加量应根据有效量及啤酒品质来确定。(丹妮) 相似文献

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. 相似文献

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. 相似文献

史前文化时期的酿酒(二)--谷芽酒的酿造及演进 总被引:1,自引:0,他引:1
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。 相似文献

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. 相似文献
