窖龄在30年以上的发酵窖池均可称为“老窖”,老窖均被名酒厂视为看家之宝。中国老窖以浓香型白酒的发酵窖池为代表,分布广、数量多,窖龄越长,其产酒质量越好。我国古籍有关“窖”的记载很多,众说不一。中国酒窖和中国酒文化的发展受地理因素、技术因素、需求因素和文化交流因素等褚多因素影响。在中国酒文化发展的各个领域内的研究尚待深入。  相似文献

随着人们生活水平的提升,饮料酒的消费逐渐上升,引起了市场监管和更多消费者对其品质和乙醇检测方面的关注。因此开发一种操作简单、检测迅速且结果直观的新型乙醇检测器十分必要。作者设计并制备了用于检测饮料酒中乙醇的聚二乙炔(polydiacetylene,PDA)囊泡,通过饮料酒中乙醇对PDA囊泡结构的扰动和基团的作用,使囊泡由无乙醇存在时的蓝色逐渐转变为有乙醇时的红色,从而检测产品的乙醇体积分数。结果表明,乙醇体积分数为30%~90%时,与PDA囊泡的比色响应(colorimetric response,CR)值具有良好的线性关系,在实际酒样检测中的相对标准偏差为1.45%~2.23%,裸眼识别颜色变化效果较好。此方法具有高效便捷、结果可视化、反应迅速的优点,为饮料酒中乙醇的检测提供了新方法。  相似文献

中华酒文化振兴的实质--白酒文化与竞争力之一   总被引:3,自引:0,他引:3  
振兴中华酒文化应从振兴中国白酒文化开始,而这种振兴不只是学术上的振兴,更重要的是在市场上的振兴,酒文化是一种非常有特色的中华传统文化,她形成和体现了具有灵魂作用的民族精神,挖掘、创新酒文化,就是要挖掘酒文化中孕育的民族精神,目前,我们的酒文化没有核心,企业推崇自己的地域文化,造成酒文化多元化突出,整体性不强,其次是酒文化挖掘力度不够。  相似文献

This study looked at the effects of an operation used by some French cider makers in order to optimise the process. The technique examined is one that consists of reducing the yeast population during fermentation, so that the fermentation velocity decreases. At different stages of the fermentation, several decimal biomass reductions were performed and their effects were determined both by counting the two main yeast populations (fermenting yeast and oxidative yeasts) and by analysing the main parameters involved in yeast growth and fermentation (total nitrogen, density). In the present experiments, it was shown that a single decimal biomass reduction was enough to control the fermentation once the density of the untreated raw juice had undergone a 5 to 10 point drop corresponding to the consumption of about 13–26 g sugar per litre. This drop was linked to the growth phase of the yeasts in the untreated assay. When this reduction was performed later, the fermentation velocity became too low to reach the expected density. Nitrogen consumption appears to be one of the key parameters of this operation.  相似文献

The biogenic amines tyramine, putrescine, cadaverine, 2-phenylethylamine, histamine and tryptamine were determined in 13 kinds of alcoholic beverages produced in Taiwan. They were derivatised with dansyl chloride and analysed using a high-performance liquid chromatographic method. Total amine content ranged from 0.23 to 11.4 μg ml?1 with Charng Chuen liqueur containing the highest level and Mei Kwei Lu the lowest. Tryptamine was found in all samples in amounts between 0.01 and 1.79 μg ml?1. The levels of the other five amines in the tested samples were 0-7.0 μg ml?1 for 2-phenylethylamine, 0-3.0 μg ml?1 for putrescine, 0-2.9 μg ml?1 for cadaverine, 0-4.5 μg ml?1 for histamine, and 0-1.4 μg ml?1 for tyramine. These levels seem unlikely to have adverse effects on human health.  相似文献

Mead is a traditional alcoholic beverage obtained by fermenting must and can offer a solution to honey over‐production and a way of valorizing honey of lower quality. The purpose of this study was to produce and characterize mead with different levels of sugars and alcohol obtained from honey from Melipona scutellaris. The honey used for mead preparation was analysed in order to ensure that it met the required quality standards. It was found that the alcoholic content and volatile acidity were outwith the limits established by Brazilian law. Mead legislation is based on the product obtained from Apis mellifera (‘honey bee’) honey and these results indicate the need to re‐evaluate the standards established for this product in order to incorporate mead produced from honey from stingless bees of the genus Melipona.

考察了7种常见的无机盐对乙醇-水溶液产生相分离的影响,实验结果表明,K2HPO4分相能力最强。通过研究常压、25℃条件下乙醇-K2HPO4-水体系的相图得知,任意体积分数的乙醇-水溶液均可在加入适量的K2HPO4后形成双水相。因此,可在酒类饮料中加入K2HPO4使其形成双水相后,通过测量上相体积来分析饮料中的酒精含量。葡萄酒中的色素、单宁对测定有影响,可以通过加入ADS-8吸附树脂和铬皮粉消除。应用本方法成功测定了白酒、葡萄酒、白兰地酒的酒精度,方法简单、快捷,样品测定标准偏差小于3.0%,回收率为99.2%~101.6%,可以满足酒类饮料酒精度标称含量偏差小于±1.0度的分析要求。   相似文献

氨基甲酸乙酯存在于黄酒、葡萄酒等酒精类饮料中,对人体具有潜在致癌作用,已被国际癌症研究机构确定为2A级致癌物。随着我国居民生活水平不断提高,酒精类饮料的消费量日趋上升,导致人均氨基甲酸乙酯的暴露量也日益上升,但是我国目前仍未对饮料酒中氨基甲酸乙酯做出限量标准。自从1985年加拿大报道了酒中有较高的氨基甲酸乙酯含量后其检测方法备受兲注,本文介绍了用于检测饮料酒中氨基甲酸乙酯的常用方法如气相色谱法、气相色谱质谱联用法、高效液相色谱法、薄层色谱法、傅里叶变换近红外光谱法等,幵简述了其特点及应用。以期能为饮料酒中氨基甲酸乙酯检测方法的发展提供参考,同时,我国应尽快对饮料酒中氨基甲酸乙酯做出限量标准以保障饮料酒行业快速、健康发展,保护我国居民健康。  相似文献

Results of a survey of levels of ethyl carbamate (EC) (urethane) in alcoholic beverages carried out in four successive years from 2009 to 2012 by gas chromatography-mass spectrometry (GC/MS) are presented. The beverages were purchased for sampling from Hebei Province of China, including eight main areas of production. The samples comprised wines (n = 212), grain spirits (n = 143) and wine sauces (n = 164). The data show that the average EC content in these kinds of alcoholic beverages remains nearly constant over the years. The results provide valuable data for food authorities to establish maximum limits for EC in China.  相似文献

Baijiu is a Chinese spirit which is produced by a complex process involving solid state fermentation with various raw materials and a consortium of microorganisms resulting in an abundance of fermentation by products. A method was developed for quantification of 62 compounds in Baijiu spirits using simultaneous direct injection to two columns (CPWax-57CB and DB-624). Dual column analysis substantially increased the reliability of identification using a flame ionisation detector. The method had high linearity - for all but one compound - indicated by the coefficient of determination (R2) of ≥ 0.999 (in a range of 0.3 – 260 mg/L) and reproducibility (for the majority of compounds at a concentration of ca. 1 mg/L, < 5% for the DB-624 columns and < 8% for the CPWax-57CB column). The limit of detection was < 1 mg/L for all compounds. The method was used to analyse volatile compounds in 38 samples of Baijiu, from different regions and flavour types. The main group of compounds in the volatile fraction were esters and higher alcohols. Based on Orthogonal Partial Least Squares Discriminant Analysis it was not possible to separate the samples in terms of region, but it was possible to distinguish between strong and soy sauce types of Baijiu from the other samples. © 2020 The Institute of Brewing & Distilling  相似文献

The concentrations of 12 metals (Cd, Pb, Ni, Cr, Cu, Co, Fe, Mn, Zn, Ca, Mg and K) in 13 classes of alcoholic beverages were determined by atomic spectrometry after HNO3/H2O2 digestion. The mean concentrations of metals (µg mL?1) in these alcoholic beverages varied in the ranges 0.01–0.04, 0.02–0.24, 0.04–0.13, 0.01–0.28, 0.01–0.77, <0.001–0.12, 0.28–1.48, 0.004–0.33, 0.10–1.02, 1.43–162.86, 0.26–25.46 and 0.49–322.58 for Cd, Pb, Ni, Cr, Cu, Co, Fe, Mn, Zn, Ca, Mg and K respectively. The concentrations of metals found in these particular alcoholic beverages were below the International Statutory Limits for metals in alcoholic beverages. The estimated daily intake of the metals based on a per capita consumption of 3.6 L per annum pure alcohol was <3% of the tolerable daily intake of each metal. The individual and combined target hazard quotients of the metals were <1, indicating no long‐term health concerns from the consumption of these alcoholic beverages based on their metal content alone.
