中国白酒拥有几千年酿酒史,秉承着世界上最为繁复的酿酒工艺,但在国际烈性酒市场上影响力却很有限,销售市场主要限于国内,特别在烈性酒消耗量非常大的欧盟国家,白酒出口额度更低。本文通过对欧盟烈性酒相关法律法规的整理、研究,在欧盟食品安全监管体系的框架下,从欧盟食品基本法、食品添加剂、污染物限量、烈性酒及酒精法规、食品标签、包装及接触材料等6个方面对有关烈性酒的法规进行初步探讨,以期能够为中国白酒出口欧盟市场提供一些参考。欧盟主要是通过食品标签法规与食品添加剂等法规结合使用来保障食品安全,对于中国白酒而言,理化成分基础研究方面是其薄弱一环。因此,应学习世界其他蒸馏酒、葡萄酒的基础研究经验,特别是借鉴国外前沿的研究方向与研究方法,夯实基础,力求在理化成分的基础研究方面取得突破性进展。 相似文献

BACKGROUND: A major factor influencing tobacco use is its price. Fiscal policies on tobacco are a key ingredient of any comprehensive control strategy, as they can be used to raise prices. The European Union (EU) developed directives to ensure some harmonisation of the fiscal pressure on tobacco across its member states. OBJECTIVES: To provide a simple comparison of tobacco prices in the EU, adjusting for the purchasing power of each currency. DESIGN: For price comparisons, a 20 units pack of Marlboro was the reference product, and data refer to April 2000. Purchasing power parities (PPP) for each member state currency have been compiled. These are currency conversion rates, which convert to a common currency and equalise the purchasing power of different currencies. MAIN OUTCOME MEASURES: Nominal prices of a Marlboro pack for each member state, and a price index, estimated taking as reference the EU mean. Adjusted prices and an adjusted price index have been estimated using PPP. RESULTS: Nominal prices show wide variation, with the cheapest pack in Portugal (59) and the most expensive in the UK (196); the range of variation is three-fold. However, PPP adjusted prices reveal a different distribution. In three countries adjusted prices are outliers, but all other countries make two clusters, one around the average EU index of 100, the other around a lower value of 85. CONCLUSIONS: These results suggest that fiscal harmonisation policies in the EU do not have an even effect at reducing availability by its impact in price. 相似文献

This paper describes the operation of the European Union Reference Laboratory for Feed Additives (EURL) and its role in the authorisation procedure of feed additives in the European Union. Feed additives are authorised according to Regulation (EC) No. 1831/2003, which introduced a completely revised authorisation procedure and also established the EURL. The regulations authorising feed additives contain conditions of use such as legal limits of the feed additives, which require the availability of a suitable method of analysis for official control purposes under real world conditions. It is the task of the EURL to evaluate the suitability of analytical methods as proposed by the industry for this purpose. Moreover, the paper shows that one of the major challenges is the huge variety of the methodology applied in feed additive analysis, thus requiring expertise in quite different analytical areas. In order to cope with this challenge, the EURL is supported by a network of national reference laboratories (NRLs) and only the merged knowledge of all NRLs allows for a scientifically sound assessment of the analytical methods. 相似文献

Despite the publication of a few contrary indications, the general consensus seems to be that the regular consumption of probiotic cultures, perhaps accompanied by 'prebiotic' compounds, improves the healthy operation of the digestive system of a typical consumer. Whether other benefits follow is a more contentious issue, especially for a given individual. Nevertheless, the dairy industry needs to be aware of the various ideas that are currently being explored, and this brief review seeks to summarize some recent findings. 相似文献

Dairy products, characterized by rich nutrition and unique flavor, occupy an increasing share of the human diet with the development of higher living standards. However, trace hazardous contaminants in dairy products, such as polycyclic aromatic hydrocarbons (PAH), are arousing public concern. In this study, we investigated 82 milks and milk powders from Shanghai markets for the occurrence of 20 PAH, including 16 European Union priority (EU 15+1) PAH and 4 derivatives. Furthermore, we carried out a risk assessment of dietary exposure of PAHs from dairy products based on detection results and data on body weight and dietary intake obtained from questionnaires. Two assessment methods were used in this study: the incremental lifetime cancer risk (ILCR) and margin of exposure (MOE) methods. The ILCR of all age groups was 10?6 to 10?4, indicating a potential but acceptable carcinogenic risk. The MOE of the 4 groups (divided by age and sex) was >104, indicating no significant carcinogenic risk of PAH exposure from dairy products. In both methods, children had the highest risk because of their greater consumption of dairy products, followed by seniors, young adults, and middle-aged adults. Results of this study provide reference data on the exposure level and health risk of PAHs from dairy product intake. 相似文献

传统发酵乳制品中微生物多样性研究 总被引:1,自引:0,他引:1
为了探究传统发酵乳制品中核心菌群,本研究采用454焦磷酸测序技术对传统发酵酸牛奶、酸马奶和酸驼奶样品中微生物的群落多样性和丰度进行了分析。研究发现,在三份传统发酵乳制品中存在一定共有微生物群。这部分共有微生物的OTU(可分类操作单元)数目较少,但拥有较大比例的序列数。在门水平上,三份样品细菌和真菌菌门分别以Firmicutes(硬壁菌门)和Ascomycota(子囊菌门)为主。在属水平上,酸牛奶样品中的细菌属以Lactococcus(乳球菌属)为主,真菌菌属以Galactomyces(耐碱酵母属)为主;酸马奶样品中的细菌属以Lactobacillus(乳杆菌属)为主,真菌属以Vanderwaltozyma(范氏酵母属)为主;酸驼奶样品的优势细菌属以Lactobacillus(乳杆菌属)为主,优势真菌属以Galactomyces(耐碱酵母属)为主。在三份样品共有菌群中Lactococcus与Galactomyces、Lactococcus与Leuconostoc(明串珠菌属)的相对含量存在显著负相关(p<0.05),Leuconostoc与Galactomyces、Gibberella(赤霉菌属)与Prevotella(普氏菌属)的相对含量存在显著正相关(p<0.05)。结果表示,在三份传统发酵乳制品中存在共有微生物群落,且该微生物群群落之间存在一定相关关系。 相似文献

以近些年来我国出现的众多"劣质乳制品"事件为出发点,结合利益相关者和多源流理论,从博弈论的角度,对监管部门、媒体、厂商各自的期望收益和策略选择过程进行了分析。认为监管部门监管不力、媒体监督不够、消费者自我维权不足、厂商社会责任感不强是导致社会上"问题乳制品"泛滥成灾,给消费者造成巨大伤害、政府公信力受损的主要原因。在"构建和谐社会"等治国理念下,结合我国政府监管、媒体监督的现状,提出加大生产劣质乳厂商的处罚、对媒体监督奖励、消费者与媒体的联合监督、地方监管部门加强监管、建立完善的投诉和检测制度等政策,对乳制品产业健康发展以及建设和谐社会具有重要意义。 相似文献

Since its inception, the European Union (EU) carbon emission market has been vastly successful in reducing greenhouse gas emissions. Accordingly, the usage of environmentally friendly fuels (e.g., ethanol, biodiesel) has increased significantly over the last few years. Given that EU biodiesel is mainly produced from rapeseed oil and soybean oil, higher carbon taxes are likely to increase the demand of these important vegetable oils, which further affects the prices of its close substitute such as butter. Nevertheless, the association between the EU emission trading scheme and butter prices remains understudied. In this paper, we aim to fill this vacuum in the existing literature. Applying the autoregressive distributed lag bound testing procedure, we show that emission market seems to have a long-term effect on EU butter prices, implying that changes in the levels of carbon taxes will lead to changes in the price level of butter. These results are of vital importance to policymakers and investors. 相似文献
