The dairy industry has grappled with numerous challenges over the years, leading to significant distrust. Prominent examples include the salmonella-contaminated milk incident in France and the adulterated milk case in China. Both incidents eroded consumer faith in dairy products. Moreover, there’s a growing concern over ethical issues such as fair compensation for producers and the welfare of animals, challenging conventional milk production practices.
In response to these challenges, the use of blockchain technology in the dairy sector has surged, offering a beacon of hope. Recognized for its potential, blockchain has become the favored choice for dairy stakeholders aiming to enhance transparency and traceability in their operations.
Enhancing Traceability from Farm to Table
Utilizing blockchain in the dairy sector facilitates monitoring dairy products throughout their lifecycle – from origin at the farm to the consumer’s table. This creates an unalterable record of a product’s path, ensuring greater food safety and minimizing waste. By swiftly pinpointing and recalling compromised products, risks can be mitigated. Furthermore, blockchain provides a platform for logging and monitoring data about dairy product quality and safety, ensuring they align with both regulatory mandates and the anticipations of consumers.
Key Focus Areas for Blockchain in the Dairy Industry
Ensuring Nutritional and Food Safety
Blockchain technology has revolutionized the way every milk batch within the supply chain is tracked. If a food-borne illness emerges, pinpointing the compromised source becomes straightforward with blockchain, allowing for swift isolation and rejection of the affected batches.
Mitigating the Impact of Spoilage
In cases of product recalls, blockchain’s precision plays a vital role. Instead of resorting to widespread recalls that could involve unaffected products, blockchain allows for targeted actions. This precision not only reduces food wastage and associated costs but also safeguards a brand’s reputation.
Strengthening Collaborations
As a decentralized and distributed ledger, blockchain acts as a reliable intermediary, ensuring trust among stakeholders. From feed mills and farmers to brands and retailers, every participant in the dairy supply chain can securely share information. This interconnectedness guarantees that a product’s entire lifecycle can be traced, ensuring all parties are compliant.
Prioritizing Transparency
Distinguishing oneself in the market can be achieved by ensuring a product’s journey is transparent. Blockchain empowers consumers by providing insights into a product’s comprehensive history and quality checks. Research indicates that consumers value this transparency, often willing to pay a premium for products that resonate with their values and beliefs, especially when ample information is provided.
Validating Credentials
Blockchain aids in bolstering trust by providing verifiable proof of product claims and certifications. For instance, when essential data is shared with independent certifying bodies, blockchain facilitates the verification of certificates, whether they pertain to origin, environmental impact, or animal welfare. This not only streamlines the certification process but also makes the information more relevant and valuable to the consumer.
Here’s how blockchain can be applied to the dairy industry
Incorporating blockchain technology into the dairy supply chain means registering all stakeholders in the system. Each participant receives a unique digital identity and profile. One of the primary advantages of coupling blockchain with Radio Frequency Identification (RFID) and cloud storage is the ability to store critical data in the cloud while ensuring secure access to authenticated farm members.
Safeguarding the data’s integrity and reliability is paramount, and blockchain excels here by utilizing data hashes for this very purpose. Dairy farmers can provide updates encompassing details such as location, breed specifics, age, weight, milk quantity per animal, medicinal records, and other pertinent treatments. This comprehensive data about milk quality can be relayed to chilling or milk collection centers.
Here’s a snapshot of how blockchain would be integrated with RFID tags on dairy farms:
- Upon ID input, the system archives the user’s details and access date.
- Post data entry, an RFID ear tag scan helps identify the animal.
- After identifying the user, date, and animal, updates on weight, age, and herd details, among others, can be made.
- The system then forms a data block, verifying its hash code.
- Once validated, this hash finds its storage space on a cloud server.
- Subsequently, the blockchain communicates this hash code to a localized server.
- With the right access code, previously local server-held data gets transferred to the cloud, becoming accessible to other network members.
Given the expansive nature of farms, it might not always be cost-effective to establish blockchain and RFID systems across vast stretches. Here, an offline synchronization feature proves advantageous, allowing for data modifications offline that can later sync with the cloud when online.
Ensuring milk remains in optimal condition during transport is critical. This is where various sensors come into play, monitoring the milk under ideal environmental conditions such as temperature and humidity. IoT-enabled trucks and storage solutions ensure product safety during transport. Real-time tracking is made possible with GPS, with the entire journey’s data recorded on the ledger.
Certification agencies, too, can join this blockchain network. Armed with digital profiles, they can supervise the plethora of data supplied by farmers and dairy processors. This data allows them to perform audits, verifying if certain standards, such as organic certification or working conditions, are met. Not only does this streamline the certification process, but it also allows dairy businesses to highlight these certifications, bolstering consumer trust.
Blockchain can further be used to encode product details, like nutritional value and genuineness, ensuring the supply chain remains transparent and secure. While QR codes represent an advancement over traditional barcodes in terms of data storage capacity, they have their limitations. In contrast, blockchain equips both companies and farmers with a mechanism to validate specific quality markers and the product’s origin. Especially for high-end products that are often susceptible to counterfeiting, this helps mitigate potential economic setbacks.
Is blockchain already being used in the dairy and food sector?
Prominent tech corporations such as IBM, Infosys, and Windows have recognized the expansive potential of blockchain in the food supply chain and are actively developing tailored solutions. IBM has introduced the Food Trust, a modular approach aimed at catering to the diverse needs of participants within the food ecosystem. Simultaneously, Windows’ Azure Workbench serves as the nexus, bridging enterprise ledger technologies in various industries, IoT devices, and broad-scale SaaS with adapters.
Take the example of Prospérité Milk, which has pioneered a digital milk system that is both traceable via blockchain and verified with continuous audits. This initiative, developed in collaboration with Connecting Food, empowers consumers by enabling them to authenticate the product’s claims, such as its origin from “Hauts-de-France,” commitment to “animal welfare,” or a “GMO-free” diet for the livestock. Remarkably, the entire process of uploading data to the blockchain bypasses any human intervention, ensuring a seamless flow of information.
In another stride toward transparency, Nestle collaborated with Microsoft Digital to pilot a system, fortified with IoT, that meticulously tracks the journey of its iconic Bacio Perugina chocolate throughout its supply chain.
Shifting the focus to seafood, top-tier shrimp growers in Ecuador have embarked on the Sustainable Shrimp Partnership. By allying with IBM’s Food Trust blockchain infrastructure, they’ve laid the foundation for a robust platform dedicated to data sharing. This platform not only allows stakeholders to monitor the shrimp’s journey but also confirms the shrimp’s adherence to standards set by entities such as the Aquaculture Stewardship Council.
Walmart, a major retail chain, ventured into blockchain quite early on. In collaboration with IBM, they’ve implemented a system to trace a spectrum of products ranging from dairy and meat to fresh fruits and greens.
