食品安全问题已经成为世界关注的热点,鹿茸作为贵重药品,其可追溯系统的研究势在必行。在鹿茸产品可追溯系统中,鹿在进入取茸环节后可能受到各种危害因素,会更多影响其后产品的质量。因此,如实的跟踪、记载鹿茸产品加工环节的各种数据信息是构建鹿茸产品可追溯系统的重要组成部分。分析了鹿茸产品可追溯系统中加工环节数据元的重要性,并提出拟采集的关键元数据规范草案并对其进行相关说明。为政府相关部门和鹿场建立标准及养殖规范提供参考,并为日后鹿茸产品可追溯系统的建立提供坚实的基础。 相似文献

消费者行为对农产品质量安全追溯体系的影响 总被引：1，自引：0，他引：1
近年来国际国内农产品质量安全问题的频繁发生使得农产品安全问题已经成为世界关注的焦点,理论研究和全球经验表明农产品可追溯体系具有确保农产品质量安全的基本功能。然而,农产品可追溯系统涉及到众多的行为主体,消费者作为可追溯性农产品的使用主体,他们的行为对农产品追溯体系的建设和发展有着重要影响,但目前从这个角度展开的研究很少。基于此背景,本文运用消费者行为理论来分析影响消费者购买可追溯农产品行为的影响。 相似文献

Traceability of ingredients in food supply chains has become paramount in a world in which markets become global, heterogeneous, and complex and in which consumers expect a high level of quality. The food supply chain consists of many organizations having different interests and are often reluctant to share traceability information with each other. Blockchain has been advocated for improving traceability by providing trust. Yet, practice proved to be more stubborn. The goal of this paper is to identify boundary conditions for sharing assurance information to improve traceability. Four cases in the food supply chain have been investigated using a template analysis of 16 interviews. Eighteen boundary conditions categorized in business, regulation, quality and traceability categories have been identified. Some boundary conditions were found in all supply chains, whereas others were found to be supply chain specific. Standardization of traceability processes and interfaces, having a joint platform and independent governance were found to be key boundary conditions before blockchain can be used. Our findings imply that supply chain systems have first to be modified and organizational measures need to be taken to fulfill the boundary conditions, before blockchain can be used successfully. 相似文献

Clinicians request a large part of measurements of biological quantities that clinical laboratories perform for diagnostic, prognostic or diseases monitoring purposes. Thus, laboratories need to provide patient’s results as reliable as possible. Metrological concepts like measurement uncertainty and metrological traceability allow to know the accuracy of these results and guarantee their comparability over time and space. Such is the importance of these two parameters that the estimation of measurement uncertainty and the knowledge of metrological traceability is required for clinical laboratories accredited by ISO 15189:2012. Despite there are many publications or guidelines to estimate the measurement uncertainty in clinical laboratories, it is not entirely clear what information and which formulae they should use to calculate it. On the other hand, unfortunately, there are a small number of clinical laboratories that know and describe the metrological traceability of their results, even though they are aware of the lack of comparability that currently exists for patient’s results. Thus, to try to facilitate the task of clinical laboratories, this review aims to provide a proposal to estimate the measurement uncertainty. Also, different suggestions are shown to describe the metrological traceability. Measurement uncertainty estimation is partially based on the ISO/TS 20914:2019 guideline, and the metrological traceability described using the ISO 17511:2020. Different biological quantities routinely measured in clinical laboratories are used to exemplify the proposal and suggestions. 相似文献

Blockchain technology provides us a new tool to solve the product traceability problem in supply chain management. This research focuses on the cross-border e-commerce context, to propose a blockchain-based framework, and develop a set of corresponding techniques and methods for achieving traceable products and transactions in supply chain management. A general blockchain-based product traceability framework is introduced. This framework is based on a cross-border e-commerce supply chain context, incorporating a series of blockchain-based models, including multi-chain structure model, data management model and block structure model. Several core methods and algorithms are also developed, such as information anchoring method, key distribution method, information encryption algorithm and anti-counterfeiting method. The framework, models and methods form a complete and comprehensive solution, which are evaluated by applying to several typical problems and attack cases. The case analysis results show that the framework, models and methods can successfully deal with key recover problem, and protect against clone attack, counterfeit tag attack and counterfeit product attack. The effectiveness, extendibility, security, implementation and governance issues of applying these solutions are also discussed. This research contributes to the theoretical and practical literatures on blockchain technology, cross-border e-commerce and supply chain management research fields. 相似文献
