微生物食品污染引发的食源性疾病是目前世界范围内最突出的食品安全问题之一,因此食品检测方法的基本需求是快速和准确,有效分析技术对于食品安全工作同样是非常重要的。文章对比分析全自动微生物定量分析仪检测技术和传统检测技术,检测海产品和烘干机肉微生物,结果是前者检测敏感性和准确性都比较高,但是也有一定局限性。 相似文献

培养基(culture medium)是由人工方法配制而成,专供微生物生长、繁殖、代谢和产物的合成提供必需的营养物质。因此,培养基的组成和配比合适与否,对微生物的生长发育会产生相当大的影响。目前,食品微生物检验中所用培养基多数为商业化生产的合成品,使用起来方便、快捷,避免了因为人工配制过程而产生的偶然误差。因为培养基质量的好坏直接影响到实验结果的可靠性,所以商品培养基的选择与使用,在实际检验工作中显得尤为重要。针对实际检验工作情况,特提出以下方塞. 相似文献

基于过程控制的食品冷链管理探索 总被引:3,自引:0,他引:3
传统的食品质量和食品安全被定义为不变色、不变昧、不变形等外在的商品特征;而新的食品质量的内涵包含了食品生产、加工、流通、销售等若干环节。民以食为天,要确保食品安全,必须加强食品冷链管理,对食品的加工和流通全过程进行控制。在经济持续发展和生活质量不断提高的形势下,冷链物流应如何快速健康发展,已成为一个紧迫的课题。发达国家在这方面有许多值得学习和借鉴的经验。通过调查研究,我们把发达国家食品冷链物流的主要做法和经验加以总结,希望为我国食品冷链物流的健康快速发展和食品冷链物流方面的政策措施制定提供参考依据。 相似文献

Over the last four decades, a large number of structural models have been developed to estimate and price credit risk. The focus of the paper is on a neglected issue pertaining to fundamental shifts in the structural parameters governing default. We propose formal quality control procedures that allow risk managers to monitor fundamental shifts in the structural parameters of credit risk models. The procedures are sequential — hence apply in real time. The basic ingredients are the key processes used in credit risk analysis, such as most prominently the Merton distance to default process as well as financial returns. Moreover, while we propose different monitoring processes, we also show that one particular process is optimal in terms of minimal detection time of a break in the drift process and relates to the Radon–Nikodym derivative for a change of measure. 相似文献

Urban flooding, frequently occurring in metropolitan areas, is one of the largest disasters worldwide. Albeit a large number of approaches and Enterprise Information Systems (EISs) have been designed for urban flood control, the ineffective management of physical assets has greatly impeded their deployment. Managing diverse physical assets is critical in urban flood control. Challenges exist in sharing assets and services between agencies, and ensuring real-time and flexible decision supports. This paper proposes a cloud-based asset management platform. Cloud technology is adopted for processing the huge amount of data collected by various physical assets and for providing flexible access interfaces. Service-oriented methods are applied to facilitate the sharing of assets and services and to enable the development of flexible and scalable Decision Support Systems (DSSs). Moreover, the concept of smart asset is introduced for remote real-time data collection, and the corresponding software agent model is developed to wrap these diverse assets, realising the UPnP (Universal Plug and Play) working mode. Finally, a case study on the urban flood control process of Guangqumen Bridge in Beijing is provided to illustrate the asset management processes of the proposed platform. 相似文献

ABSTRACTA map traceability management scheme for security control is proposed utilising visual cryptography and Quick Response Code. The map information is classified into two categories: the public information MPI and the traceable map information MTI, and they are both converted into QR codes. Map shares MS and control shares CS are generated according to extended multiple visual cryptographic scheme. MPI can be obtained by scanning the MS, while MTI can be got by overlaying the MS on CS which is only accessible to management units, so it can identify every map and provide the basis for the traceability management. 相似文献

This study suggests that the behavior of demand of cash by business firms can better be understood by empirical testing theory on data derived from individual units rather than making unrealistic assumptions to justify testing of aggregated data. Using data for firms in the food industry, this study shows that the rate of interest is a significant variable in explaining the demand for cash. Furthermore, the statistical results indicate that the economies of scale in the management of cash depends upon the type of goods produced by the corporations under study. Accordingly, one cannot make any generalization regarding the question of the economies of scale in the management of cash. 相似文献
