During the past couple of years, blockchain technology has become easier to implement for even small- and medium-size participants, thanks to large suppliers like IBM providing specific application-based blockchain technology (IBM Food Trust) and Amazon Web Services providing backbone networking architectures. In addition, smaller blockchain providers now have dedicated applications that can trace food not only to the farm and field in which it originated, but the very seed as well, while also providing complete supply chain visibility for all participants, including consumers.
You might consider blockchain’s “early days” to be about five years ago—when Walmart and IBM were first researching the viability of using blockchain in the food industry. Back then, large programming efforts were typically necessary to create a functional blockchain. Today, blockchain applications are becoming almost as easy to use as email.
In this article, we look at blockchain development and survey its practicality for processors—even small and medium-sized food and beverage companies. (Another article in the form of a panel discussion, entitled “Getting Started with Blockchain,” covers how blockchain networks are initiated and the mechanics of creating them and bringing suppliers on line.)
Blockchain highs and lows
You’ve no doubt heard that blockchain functionality can be used to secure supply chain operations and provide an immutable record of all activities from farm to fork, making the technology so highly practical for track and trace that FDA has been looking into its application for food safety. In addition, blockchain technologies can discourage theft and product tampering, as well as manage the tracking of lower-cost perishable food and high-end products like rare specialty wines.
Because Penfolds Magill Estate Winery in South Australia produced only 13 barrels of its vintage 2021 Shiraz Cabernet Sauvignon, the asking price is $130,000 for a single barrel—truly an investment. In fact, Penfolds has become the first winemaker to partner with BlockBar, a non-fungible token (NFT) marketplace using blockchain technology for luxury wine and spirits products, to launch a limited edition of its specialty wine. The digital token corresponds to this particular barrel currently maturing in Penfolds’ cellars.
The single barrel NFT will be converted into 300 bottle NFTs at the date of bottling of the wine in October 2022 with the whole process verifiable through the blockchain, and each bottle being identified with a barrel and bottle number. The NFT serves as a digital receipt that verifies the buyer’s ownership and authenticity of the wine bottles. The bottle NFTs can be resold or transferred through the BlockBar platform, and follow to the actual delivery of the bottle, which in this case is no earlier than the release date in October 2023.
In the FDA’s “New Era of Smarter Food Safety” document dated July 2020, FDA Commissioner Stephen Hahn said, “Our stakeholders should be looking at how to tap into new technologies that include, but are not limited to, artificial intelligence, the Internet of Things, sensor technologies and blockchain.”
In a recent FDA “New Era for Food Safety” public meeting, a presentation given by McKinsey & Company pointed out several public news releases where blockchain technologies are being adopted by food industry stakeholders. Some of these include:
IBM’s Food Trust, which is bringing together food and agricultural companies on a blockchain traceability system.
Walmart’s plan to require all U.S. spinach and lettuce suppliers to track products on blockchain.
ADM, Bunge Ltd., Cargill and Louis Dreyfus companies are looking at ways to standardize and digitize global agricultural shipping transactions using blockchain.
Alibaba has developed a blockchain-based Food Trust framework and has filed 90 patents on blockchain technology.
Wipro joined the Blockchain in Transport Alliance, a member-based organization focused on transportation and logistics with applications in food and agriculture.
TagOne, a winner of the FDA’s Traceability Challenge, provided blockchain traceability tools for supplement ingredient manufacturer Cepham.
Simplifying blockchain systems—FDA gets involved
To spur interest in blockchain and other traceability technologies, FDA recently held its “New Era of Smarter Food Safety Low- or No-Cost Tech-Enabled Traceability Challenge.” Its purpose was to call on stakeholders—including technology providers, public health advocates, entrepreneurs, and innovators from all disciplines and from around the world—to develop traceability hardware, software, or data analytics platforms that are low-cost or no-cost to the end-user. 
The winning submissions covered a considerable range of use cases and consisted of a variety of approaches, platforms and technical designs. Twelve winning teams were identified, representing the U.S., Canada and New Zealand. Factors that identified top-performing submissions included practical solutions not requiring users to be technically proficient, demonstration of a solution that met a clear need in food traceability, integration with existing systems and a solution that reached all the way to the consumer.
Cost and connection issues
U+ is a tech consulting firm that provides a comprehensive set of services from ideation and market validation to product/software development and scaling. “Blockchain technology is slowly making an entrance into the supply chain process, but as it applies to the complexities of the food industry, its value proposition is still not clearly established,” says Jan Beránek, CEO and founder.
Even so, there are several key blockchain players in the food tracing technology space, namely IBM’s Food Trust, Ripe.io, FoodLogiQ and TE-Food, allowing consumers to verify the journey of their products, says Beránek. “Due to the complexity and varied needs of each customer, some level of customization and onboarding are still required; however, the process has been made smoother by the top players.”
“These blockchain technologies are already being utilized by many food processors, for example, TE-Food touts 6,000+ customers to track food from its origin to destination,” adds Beránek. “FoodLogiQ is working with big name customers such as Chipotle and Whole foods on the consumer side, and Conagra and Tyson on the processor side. There are also blockchain companies working on other applications within the food industry, including crop insurance, financial transactions and supply-chain optimization, which could help level the playing field for smaller farmers and producers.”
Beránek suggests that blockchain technologies are rather costly at the benefit of providing a layer of security to the information on the blockchain, and many companies throughout the supply chain would need to align in order to benefit from such tracking. “Non-blockchain standards for safety and visibility of food supply chains such as GS1 currently exist, providing a certain level of compliance and tracking off-chain,” says Beránek.
Got blockchain: GS1 provides the data structures
GS1 provides a system of globally recognized data standards that is integral to business supply chain applications, such as event data, transactional data and even master data.
Wholechain was named a winner of the FDA’s New Era of Smarter Food Safety Low- to No-Cost Food Traceability Challenge. When non-food items—such as perfumes—use food ingredients, traceability is as important as food. Aveda uses Wholechain to trace its vanilla ingredient from 450 farmers in Madagascar. The data informs the story behind the vanilla, accessible through QR codes printed on over 125 Aveda products. -Image courtesy of Wholechain
“The first thing we would do to help our customers is determine whether blockchain technology would provide adequate value for their supply chain and tracking capabilities,” adds Beránek. “In order to justify building or integrating a blockchain solution within their business, it would need to provide additional revenue, save costs, provide a competitive advantage, or meet compliance requirements. If after the validation and market testing stages we determine that blockchain technology would indeed be beneficial for the current product, we would implement it in the system architecture.”
Connecting with ERP and MES
ERP systems can be standalone, or they can connect with blockchain systems. “Blockchain can be a promising solution to tackle the transparency and traceability challenge in the food and beverage industry; however, there are other solutions that compete with blockchain, such as ERP software that already enables end-to-end traceability,” says Maggie Slowik, IFS global industry director – manufacturing. IFS doesn’t offer a blockchain solution per se; however, it has strong industry-specific ERP software. This is part of the IFS Cloud solution and helps manufacturers achieve end-to-end traceability by enabling the identification of all relevant data for the materials used in the production and distribution of finished goods, says Slowik.’
"As industry continues exploring blockchain’s potential applications, data standards will be vital to ensure interoperability for the information exchange it is intended to facilitate" — Kevin Otto, Senior Director, Community Engagement, GS1 US
“While blockchain is poised to deliver new and innovative benefits to both businesses and consumers, it’s important to understand blockchain is not a silver bullet on its own,” says Marcel Koks, Infor industry & solution strategy director for food & beverage. “The functionality, when coupled with modern enterprise resource planning (ERP) solutions and cloud-based, multi-enterprise supply chain business networks, can greatly benefit food and beverage manufacturers in their efforts to ensure the quality, safety and shelf-life of ingredients and products delivered to consumers.”
CAT Squared, a MES solutions provider, has developed two options for processors who want to enhance supply chain traceability by adopting distributed ledger technologies like blockchain, according to Kathy Barbeire, marketing manager.
“CAT Squared is the first manufacturing execution system (MES) provider in the food industry to become an onboarding partner for IBM Food Trust, a blockchain-enabled global network of food supply chain participants,” says Barbeire. “This means that CAT Squared can easily onboard users of our MES system by identifying data related to GS1 EPCIS (Electronic Product Code Information Services) events tracked within our system and contribute them to the Food Trust blockchain.”
CAT Squared has also developed its own FoodTrace solution, which is a GS1- and EPCIS-based event repository. It enables the asynchronous capture of critical tracking events occurring along the supply chain from the farm to processors and distributors, and all the way to retail consumers. “Our API configuration enables the capture of any digital signal that occurs through the life cycle of a product,” says Barbeire. “Our FoodTrace MESH application takes this further and allows for the sharing of data across supply chain players, enhancing demand, supply, and capacity planning and synchronization.”
All the traceability options mentioned here together make blockchain implementation much more attainable for small and medium-size businesses to develop solutions quickly in the current blockchain environment, with room to grow.
