Whether or not food traceability sys- tems can guarantee food safety is a problem well worth discussing. Hence, we constructed a theoretical model to explore the effect of incentives in a food traceability system in order to improve food safety levels. The following results were obtained： enhancing the ef- fectiveness of a food traceability system, increasing the payment to farmers who supply safe agricultural products and strengthening the penalty for unsafe food supply actions are necessary conditions to improve the level of food safety. How to encourage farmers to use food traceability systems is another problem explored in our investigation. Based on a field survey on the willingness of vegetable growers to participate using a vegetable traceability system in Beijing, the first city in China to develop such a system, we used a de- scriptive statistics and a binary logistic regression model to investigate the factors which dominate the decision on the part of farmers to participate in a food safety system. The results indicate that i： younger farmers are more likely to get involved in a food traceability system than older farmers, ii： income from non-agricultural activities decreases the willingness of farmers to participate, iii： the high- er the cost-benefit ratio of growing vegetables, the more likely for farmers to engage in a food traceability system, iv： farmers with a great concern for food safety information have a high propensity to participate and v： increased penalties against unsafe food supply actions and high-risk expectation are adverse incentives. In contrast, high-price expectation is a positive incentive for farmers to par- ticipate, while agricultural training, government subsidies and being part of an industrial organization will significantly strengthen the confidence of farmers to participate in a food safety system.展开更多

Semi-structured interviews were conducted with galley and foodservice staff. Additionally, a self-administered questionnaire was designed and distributed to logistics managers and employees of three Egyptian cruise companies. Results indicated that cruise ships in this study use paper-based and manually-entered (electronically stored) data traceability systems. Managing food safety by effective product recall, complying with legislation, and improving product quality are among the most important perceived benefits identified by foodservice staff. Maintaining a good reputation, ensuring food safety, reducing foodborne illnesses, suppliers' commitment to quality specifications, and maintaining vip confidence are considered the most important benefits from implementing a food traceability system. The results also depicted that the challenges managers face implementing or improving a food traceability system included high cost, absence of unified traceability standards between cruise companies and food suppliers, shortage of skilled staff, and lack of knowledge and satisfaction with current foodservice operation systems onboard cruise ships. Other findings elucidated that the critical success factors for implementing traceability included strict food traceability legislation, ensuring the adequacy and correctness of traceability information, adopting a food traceability system by the cruise company management, the standardization of food traceability information identification, and technology support for food traceability systems implementation from government. Other factors were reported of less importance. This research concluded the urgent need for more cooperation between cruise companies, food suppliers, and relevant governmental authorities to adopt food traceability systems and the need of authorizing and setting compulsory standards and regulations.展开更多

Establishing a food traceability system can effectively guarantee food safety and increase consumer confidence and satisfaction. Existing food traceability systems often ignore environmental factors that affect food quality at all stages of the supply chain, and the authenticity of the information obtained through traceability is difficult to guarantee. In this study, a food supply chain traceability model was established based on blockchain and radio frequency identification (RFID) technologies. The model focused on the traceability of environmental data during the various stages of the food supply chain and combined a centralized database and blockchain for data storage. The lot identification data of the various supply chain stages were stored in a centralized database, while the environmental data were stored in a blockchain. Thereby, the authenticity and accuracy of the traceability data were ensured. The blockchain part of the model has been simulated in the Ethereum test environment, and the experiment has achieved traceability of temperature data.展开更多

文摘The frequent occurrence of food safety accidents at the global level has triggered consumer sensitivity. Establishing a food traceability system can effectively guarantee food safety and increase consumer confidence and satisfaction. Existing food traceability systems often ignore environmental factors that affect food quality at all stages of the supply chain, and the authenticity of the information obtained through traceability is difficult to guarantee. In this study, a food supply chain traceability model was established based on blockchain and radio frequency identification (RFID) technologies. The model focused on the traceability of environmental data during the various stages of the food supply chain and combined a centralized database and blockchain for data storage. The lot identification data of the various supply chain stages were stored in a centralized database, while the environmental data were stored in a blockchain. Thereby, the authenticity and accuracy of the traceability data were ensured. The blockchain part of the model has been simulated in the Ethereum test environment, and the experiment has achieved traceability of temperature data.
文摘Objective To analyze the current problems in drug traceability and supply chain management,and build the drug traceability system based on the block chain technology so as to provide authenticity assurance for the real data in the whole life cycle of drugs.Methods A new drug regulatory traceability protocol was designed based on block chain technology.The database of drug production,circulation and use was linked closely.A traceability system was set up according to the traceability protocol,and the consensus complexity and safety performance of the system were analyzed.Results and Conclusion The distributed account book and tamper-proof functions of the block chain platform were used to establish a double-chain system based on the combination of public chain and private chain,which could make the data of drugs more reliable,transparent and traceable with good application value.The establishment of a double-chain traceability system is studied so that drug market license holders,manufacturers,operating enterprises and users can verify the data to form an interconnected drug traceability data chain.
文摘The global seafood industry is a vital and rapidly growing source of protein.Seafood traceability systems(STS)are crucial for enhancing brand reputation,mitigating risks,ensuring food safety,and building consumer trust.However,in Oman,seafood often undergoes complex journeys through multiple ports,intermediaries,and processors,making traceability a challenge.Currently,only a small fraction of wild-caught seafood can meet the demand for transparency.This study assessed the STS implementation in Oman,focusing on seafood establishments and government officials.Using Likert scales and questionnaires in English and Arabic,responses were gathered from 32 seafood establishments and 16 officials from the Ministry of Agriculture,Fisheries and Water Resources(MAFWR),Sultanate of Oman.Data analysis involved various statistical methods,including the Cronbach Alpha index for internal consistency.Results indicated that government officials primarily support STS regulations,while seafood establishments see potential benefits but anticipate implementation difficulties.The seafood industry is more optimistic than officials about STS.Bridging gaps in awareness,technology,knowledge,and research is crucial.Collaboration between the government and seafood establishments is recommended to enhance communication.Public awareness campaigns sponsored by the government and relevant organizations should promote the advantages of STS.Cost-benefit analyses should be conducted,and results should be shared with stakeholders.Further research is needed to understand the variables influencing STS adoption.In summary,enhancing seafood traceability in Oman is essential for meeting global demands for transparency and food safety.This study emphasizes the importance of collaboration,awareness,and research in bridging STS implementation gaps and eventually benefiting consumers and the seafood industry.

文摘Despite the promising prospects of blockchain technology,research remains primarily confined to the analysis-design phase,highlighting a gap in support for actual implementation.This study aims to develop a framework for assessing the implementation readiness of a blockchain-based traceability system,using the Kintamani coffee agroindustry as a case study.The research commenced with a structured literature analysis to create an assessment model and lay the groundwork for survey questionnaire distribution among potential users.Utilizing Kansei Engineering,the data were analyzed using quantification theory type I(QTT1)to identify the critical elements influencing users’adoption intentions.The findings led to the proposition of a new framework integrating the assessment model with the system development life cycle(SDLC).Analysis of 59 articles revealed that TAM,TOE,DOI,and TRI are the predominant theories used to assess blockchain technology adoption.The resulting assessment model comprises three contexts,two characteristics with 14 variables,and analyzed data showing individual characteristics—particularly elements OPT1,INS3,and DIS1—as pivotal,evidenced by their high partial correlation coefficients of 0.92108,0.89168,and 0.89050,respectively.An integrated participatory development(IPD)approach was suggested to enhance system development and improve user quality of life,interaction,and communication effectiveness in the SDLC.This novel method proposed bolstering blockchain systems’real-world implementation success by adapting development iterations to user needs.It is anticipated to apply to other case studies,offering broader implications.Future research could explore different data analysis methods or case studies to enhance these findings through sensitivity comparisons and bias analysis.

文摘Almond is widely cultivated in the world thanks to the quality and healthy features of the kernel.Almond kernel is consumed fresh or employed in the food industry.Hundreds of almond cultivars were selected throughout the long history of cultivation;in this context,an efficient method for varietal identification is essential to ensure cultivar traceability along the chain.This study surveyed the widely employed commercial kits and protocols for DNA extraction from several almond matrices including leaves,kernels(fresh and roasted)and several processed products.Commercial kits(though with minor modification)outperformed the other extraction methods for the isolation of DNA suitable for molecular analysis from all the tested matrices.In parallel,a germplasm collection composed of 140 accessions(123 Sicilian genotypes complemented with widely known national and international cultivars)was genotyped with the Axiom^(TM)60K almond SNP Array enabling the detection of 6374 unique SNPs that can be readily used for varietal traceability.A subset of unique SNPs was further validated employing a high-resolution melting(HRM)assay on a discovery panel encompassing ten of the most widely cultivated accessions.The DNA extracted from leaves and kernels of five cultivars was genotyped with eight SSRs allowing the identification of the maternal origin of each kernel.The paper integrates the survey of the widely employed protocols for DNA extraction with the high-throughput genotyping of 140 almond accessions.In this context,unique SNPs validated and optimized for an HRM assay and the availability of SSR markers demonstrated their efficacy in traceability analysis along the chain.
