美国BeefChain公司使用区块链来进行牛肉的食物溯源

2020-7-27 13:42

 

“世界正在改变……区块链真的是唯一的出路,”Steven C. Lupien, BeefChain的总裁和联合创始人


食品可追溯性已成为食品行业的一个优先事项,消费者要求更健康的产品结合各种不同的转基因、激素和草饲属性。一旦食品相关的健康风险被发现,公司和政府都在努力应对后果。以2006年美国的菠菜和大肠杆菌疫情为例。试图通过从零售商到农民的供应链追踪爆发的原因需要做很多工作,包括监管人员。反过来,它破坏了公众对供应链的信任。


不仅某一特定产品或公司的声誉直线下降,食品可追溯性处理不当也可能对该公司造成毁灭性打击。由于美国花生公司(PCA)参与了“美国最大规模、最致命的食品污染事件之一”,该公司已不复存在根据《食品加工》杂志的说法。据估计,该行业在生产和销售方面损失了10亿美元,其中一名高管最终被判入狱28年。


一家名为BeefChain的区块链创业公司,利用这项技术,消费者可以追踪他们的牛肉产品。2019年4月,牛肉连锁店通过流程验证项目获得美国农业部(USDA)认证。这意味着某些特性,如不含激素,按照美国食品安全法规进行审核和认证。


今年,BeefChain与技术公司IOHK合作,后者是Cardano上市区块链的幕后推手。通过支持BeefChain使用Cardano和IOHK Atala跟踪解决方案,IOHK将帮助BeefChain在区块链跟踪方面的技术工作。BeefChain与怀俄明大学合作,后者从IOHK获得了50万美元的加密货币捐赠,用于支持其区块链研发实验室。


有了BeefChain,牧场主们将从每一头他们标记的奶牛身上看到巨大的投资回报。由于BeefChain获得了美国农业部“流程认证计划”的批准,牧场主可以以每磅0.05-0.50美元的价格出售牛肉,每头牛的售价可达3万美元。此外,使用区块链可能消除供应链中的一些中间商,尽管这还没有被使用。

它是如何工作的?


牛被贴上RFID标签,每个5美元,可以上传数据到一个不可变的区块链。通过使用这些标签,小牛有一个独特的身份,可以跟踪它的成长过程,出售,并通过供应链转移到零售商。消费者可以使用二维码访问这个身份,一旦扫描,就会带他们进入这家牛肉连锁店的网站和饲养他们牛肉的牧场。这一过程被作为卡尔达诺虚拟峰会的“牛排证明”部分进行了演示。


除了消费者可追溯性,在食品召回的情况下,该解决方案还可以节省大量资金。IBM和沃尔玛的一项试验发现,这种方法可以将追踪芒果来自世界各地的食品召回时间从7天缩短到2.2秒。因为可以迅速确定来源,这就避免了将货架上所有未受污染的芒果从货架上取下的浪费。


根据牛排证明峰会,牛链已经“非常接近”区块链牛肉追溯成为现实的目标,并已于2019年2月向台湾运送了第一批区块链牛肉试点。


然而,该公司也面临着竞争。在美国,成熟。io与美国的奶农有关系。在澳大利亚,有AgLive和BeefLedger,它们的目标是向中国出口。


美国食品和药物管理局(FDA)正在考虑将区块链用于食品追溯。上个月,美国GS1公司表示,它与FoodLogiQ、IBM食品信托公司、成熟公司进行了区块链试验。io和SAP。

 

The world is changing… blockchain is really the only way to go,” Steven C. Lupien, President and Co-Founder of BeefChain 

Food traceability has become a priority in the food industry, with consumers demanding healthier products combined with various GMO free, hormone free and grass-fed attributes. Once a food-related health risk is discovered, companies and governments alike struggle with the repercussions. Take, for instance, the 2006 U.S. spinach and E. coli outbreak. Trying to trace the cause of the outbreak through the supply chain from retailer to farmer involves a lot of work, including for regulators. And in turn, it devastates public trust in the supply chain. 

Not only does the reputation of a particular product or company plummet, but the mishandling of food traceability could also be devastating for the company. Peanut Corp. of America (PCA) no longer exists due to their part in “one of the most massive and lethal food contamination cases in the U.S.” according to Food Processing magazine. It’s estimated that the cost to the industry was $1 billion in lost production and sales, and ultimately, one of the executives ending up in jail for 28 years.

BeefChain, a blockchain startup, uses the technology to allow consumers to trace their beef products. In April 2019, Beef Chain achieved a United States Department of Agriculture (USDA) Certification with the Process Verified Program. This means that certain characteristics, such as being hormone free, are treated as audited and certified in line with U.S. food safety regulations.

This year, BeefChain has partnered with IOHK, the technology firm behind the Cardano public blockchain. IOHK will help BeefChain in the technological aspects of their blockchain tracing endeavor, by supporting them in using Cardano and the IOHK Atala Trace solution. BeefChain works with the University of Wyoming, which received a $500,000 cryptocurrency donation from IOHK to support its Blockchain R&D Lab.

With BeefChain, ranchers will see a significant return on investment with every cow they tag. Because BeefChain enables that USDA “Process Verfied Program” stamp of approval, ranchers can sell the meat for an extra $0.05-0.50 per pound, which can amount to $30,000 with every herd. Furthermore, using blockchain may eliminate some intermediaries in the supply chain, although this has not yet been used.

How does it work?

The cows get tagged with RFID tags, costing $5 each, which can upload data to an immutable blockchain. By using these tags, a calf has a unique identity and can be tracked as it grows, is sold and moves through the supply chain to the retailer. Consumers can access this identity using a QR code, which once scanned, will take them to the BeefChain website and the ranch from which their beef has been farmed. The process was demonstrated as part of the ‘Proof of Steak’ segment of the Cardano Virtual Summit.

Apart from consumer traceability, the solution can save significant sums in the case of food recalls. An IBM / Walmart trial found it would reduce the time of a food recall from 7 days to 2.2 seconds to track mangos’ origins from across the world. Because the source can be quickly pinpointed, it avoids the wasteful removal of all the uncontaminated mangos from the shelves.

According to the Proof of Steak Summit, BeefChain is ‘very close’ to its goal of having blockchain beef tracing become a reality, having sent the first pilot batch of blockchain beef to Taiwan in February 2019. 

However, the company has competition. In the U.S., ripe.io has a relationship with Dairy Farmers of America. And in Australia, there is AgLive and BeefLedger, which is targeting exports to China. 

The U.S. Food and Drug Administration (FDA) is mulling blockchain for food traceability and last month GS1 US said it ran a blockchain trial with  FoodLogiQIBM Food Trustripe.io and SAP.
