## Abstract

The growing need for access to safer food items is increasing, and hence, there is a need for a better supply chain management system in the food industry is increasing. The increased complexity of the existing systems tends to introduce more issues to the stakeholders, and also, the cost of product traceability is quite high. Hence, the industry is looking for effective solutions in relation to drug traceability, and the application of Blockchain technology enables the stakeholders in the food and beverage (F&B) sector to track the movement of goods, supported in gathering the required details so that the contaminated products can be identified and recalled without much delay and lesser recall costs to protect the lives of the individuals. The tampered food items are increasing and are impacting the supply chain process, brand name of the companies, and claim assurance. They create an adverse impact on the health of the individuals and cause higher economic loss to the health-care industry. The existing studies tend to focus on laying emphasis of the need for an enhanced, effective, and end tracking systems in the industry. The emergence of Blockchain technology enables centralized tracking of information support in enhancing the data privacy and increasing transparency and support in eradicating the tampered food products in the supply chain system. These approaches leverage the usage of smart contracts and decentralize the storage of information in a secure manner for enhanced product traceability in the F&B industry. The implementation of smart contracts generates better data governance, which tends to meet the needs and requirements of the stakeholders, and applies effective measures of food traceability. The primary objective of the study is to perform an analysis of Blockchain in enhancing drug traceability in the food sector. The researcher uses quantitative analysis for the study as it helps in understanding the critical determinants influencing drug traceability in food effectively, the survey method is used to gather the information, and past reviews are also used to possess a better understanding of the subject area effectively.

## Body

## 1. Introduction

The current nature and scope of food supply chain management are considered a complex network where different entities such as materials, vendors, distributors, producers, retailers, multiple processing units, and others are involved. Increased complexity not only impacts the inefficiencies in the process and creates more challenges like counterfeit food products with nonprovisioned drug traces but also impacts the food industry adversely. Although the Food Safety and Standards Authority of India (FSSAI) has passed several laws and amended them regularly to ensure food safety, its implication seems to lessen at an individual step in the process ultimately diminishing its effects. This allows the scope of malicious food tampering and practices leading to unsafe food products in the market. The counterfeit drugs in food items adversely impact public health [1]. The major contribution of the research is to conduct a comparative analysis of Blockchain in improving drug monitoring in foodstuffs. The critical determinants of the study include using Blockchain for best interconnectivity, providing critical help for stakeholders in tracking goods, and protecting against challenges and issues.The implementation of Blockchain technology has opened up a new model of application creation which is based on the implementation of the critical data structure, the basic approach is that the data structure is related to a linked list of blocks which are mainly shared through the nodes and each node possesses an original copy of the blocks [2]. The emergence of different applications such as the Internet of things, machine learning, and deep learning supports enhancing document management and enables proper tracking and traceability of the data in an effective manner. Additional complexity not only affects operational inefficiencies and generates new issues, such as fraudulent food items containing commonly used diagnostic drug residues, but also has a negative influence on the food sector. That although the Food Safety and Standards Authority of India (FSSAI) has created various regulations and revised them on a regular basis to maintain food safety, their impact appears to erode at each stage of the process, eventually reducing their impacts. These aspects can be leveraged in the food industry to track the illicit drugs in the F&B supply chain effectively. The food retailers can use the Blockchain technology to leverage the validation of the structure and support in gathering related information for each transaction, which are commonly mentioned through hashes and support in the transfer of data through a peer-to-peer network, which will make it difficult in hacking data and records [3].The application of Blockchain support in identifying and engaging the major stakeholders in food supply chain management, producers, retailers, processing units, distributors, and others, is limited to harnessing the data in an effective manner. The pharmacists enable the presentation of the external entity and support better drug traceability [4]. Blockchain has the ability to change the way food is recorded, delivered, and sold. Blockchain can eliminate errors produced by conventional paper-based records to keep each electronic record of all transactions. Food stores can use Blockchain to validate the framework, assist in gathering associated information for every purchase, which is frequently indicated via hashing, and assist in data transmission via a mentoring network. The implementation of Blockchain creates a better platform by providing better-distributed ledger solutions which are delivering a higher degree of confidentiality, support in enhancing resilience, scalability of operations, and better flexibility. The researcher has mentioned that Blockchain technology like Hyperledger Fabric is one of the critical tools which supports enhancing a suitable aspect for managing complex supply chain networks which involves better physical and logical processes; moreover, the application of Blockchain technology supports guarding against different types of cyber-attacks and malware. [5]. The food supply chain management is now governed by digital technologies, and hence, it is highly critical to protect the data in an effective manner; hence, the implementation of Blockchain supports drug traceability and safeguards the data in an effective manner [1].The primary objective of the study is to perform a comparative analysis of Blockchain in enhancing drug traceability in food products, the critical determinants of the study involved using Blockchain for better interoperability, offering critical support for stakeholders in tracking the goods and protection from attacks and vulnerabilities.The research paper has been mentioned into six components. Section1 describes the introduction of blockchain, while Section 2 focuses on the review literature. The methodology of the research has mentioned in Section 3, and Section 4 describes the data analysis. Moreover, the conclusion of the proposed research has described in Section 5.


## 2. Review of Literature

Hyperledger Fabric is a platform that delivers universal distributed solutions with a layered architecture that ensures data security, endurance, versatility, and scalability [6]. It is a business-oriented DLT based on Blockchain that employs contracts to establish rapport among many entities. Hyperledger Fabric does away with mining but keeps all of the benefits of a traditional Blockchain cryptocurrency (such as Bitcoin or Ethereum), such as unaltered block sequence determinism and double avoidance cost [7]. With hundreds or even thousands of requests per second, Hyperledger Fabric has proved to give great business performance [8]. When standard programming languages (Java, Go, and NodeJS) are used to create smart contracts, the technology’s approval rate is lower than when proprietary programming languages are utilised (e.g., solidity in Ethereum). Blockchain technology aids in the creation of an authorised secure network for detecting and tracking supply chain information events, as well as providing timestamp files for each transaction [9]. This technique will facilitate access to the food supply chain, promote collaboration among untrustworthy parties, and develop an endless and unchanging decentralised drug monitoring system. To build compatible solutions for numerous controllers, sharing of data is required [10].The successful execution of the Bitcoin application data format has given rise to a new concept for software development based on Blockchain technology. A Blockchain data structure can be compared to a linked list that is shared across the network, with each node having a copy of every block (linked to the longest chain) generated by its generator [11]. In domains such as the IoT, e-governance, and e-document handling, many authentic solutions have lately been developed. Due to its self-encrypting structure between deals (through exchanging) and the public access to a global digital ledger, these solutions reap the benefits of Blockchain technology [12]. Since it would be costly to revise from inception to final log action, establishing a Blockchain coupled with cryptographic construction makes it exceedingly impossible to break records [13].


## 3. Methodology

The methodology of the study is involved in using quantitative research design as it supports the authors to investigate the research area in an effective manner; the researcher is more focused on understanding the critical determinants of using Blockchain which supports drug traceability [14]. The research applied quantitative analysis for the research because it helps in successfully identifying the critical determinants influencing drug monitoring in food. A survey method is used to collect data, and previous evaluations are also employed to obtain a better knowledge of the subject. The primary data source is generated through the survey method. The researcher uses closed-ended questions which intend to understand the responses from the sample population on the application of Blockchain technology towards drug traceability. The authors also use secondary data sources for collecting the past reviews related to the topic [15].

The increasing complexity of existing systems often causes more problems for those involved, while the number of tampered food items is increasing in many countries [16]. Therefore, the profession seeks effective solutions in the traceability of drugs; the application of Blockchain technology allows food companies to monitor the movement of goods and support the collection of necessary data to make safe and nutritious food available to enhance human lives. The number of counterfeit products is increasing, and this affects the supply chain, recall, costs, defamation, and so on [17]. They have a negative impact on human health and lead to greater financial losses in the F&B sector. Existing studies tend to emphasize the need for a comprehensive, improved, and effective monitoring system in the industry. WHO has been studying contaminated food products and is working incessantly towards ensuring food safety and has laid down various laws for the same worldwide.When the need for food safety and security increases, a comprehensive alternative for controlling the food profession’s distribution network is required. The rising complexities of the present system frequently produce additional issues for people engaged, while the quantity of tainted food products is increased in many nations. Blockchain helps to improve document management and enables data to be tracked and detected properly. These considerations can be used in the F&B sector for effective drug monitoring throughout the food supply chain. The food manufacturing, processing, and storage facility can utilize Blockchain technology to leverage framework validation, support the collection of relevant information related to each transaction, often through breakdown, and support peer-to-peer data transfer [18]. By building Blockchain support in cryptographic construction, it becomes difficult to break data and records.

## 5. Conclusion

Blockchain application creates a better platform to provide a more distributed universal solution that provides a higher level of data protection, greater flexibility, resource scalability, and greater flexibility. Previous studies usually prefer to stress the importance of improved, comprehensive, and end-to-end monitoring systems in the sector. The implementation of Blockchain internet allows centrally managed monitoring, which aids in boosting data privacy, improving transparency, and removing defective food items in the supply chain system. The researchers said that Blockchain technology such as Hyperledger Fabric is one of the most important tools to support the development of a complex network of supply chains with the better physical and logical processes and that the use of Blockchain technology supports protection. The food supply chain is now driven by digital technology, so effective data protection is essential, so a Blockchain application supports drug traceability and protects data effectively.The advent of Blockchain technology enables centralized tracking of information assistance to improve data protection, increase transparency, and eliminate counterfeit medicines in the distribution chain. These approaches benefit from the use of smart contracts and decentralize information storage in a secure way for better traceability of food products. Implementing smart contracts creates better data management, generally meets the needs and requirements of stakeholders, and implements effective follow-up measures.
