The National Sheep Association (NSA) has launched a new project that aims to establish whether the technology exists to identify sheep breed, the animal’s age, and the location it has been grazing from meat samples.
Nicola Noble, NSA Project Manager, said, “Not all meat tastes the same and the main factors affecting the flavour are the age of the animal, it’s breed and its environment. There are many varieties of apples available, yet sheep meat is very rarely advertised as anything more than lamb. We should be embracing diversity within the UK sheep sector and allow the public to appreciate the different flavours, tastes and textures that come from the diversity.”
One reason for this is the lack of affordable and commercially viable technology to trace the heritage of meat. The first phase of this groundbreaking project is to prove the concept of using blockchain ‘distributed ledger’ technology for food traceability with a short and moderately simple supply chain.
Meat samples will be analysed using a mass spectrometer to identify the pattern of phospholipids, which will act as a fingerprint. Each piece of meat will have a unique profile based on species, breed, feed, age, geographic location and flavour profile.
Noble said, “This is the first phase to test blockchain in a short, simple supply chain. The outcome should progress to a larger piece of work to develop a simple-to-use meat traceability system giving confidence to consumers and those within the supply chain that claims made of meat are genuinely as they are described.”
The project is in its infancy, and the NSA is looking for farmers to take part.
Breeds being used for this feasibility phase of the project are Swaledale sheep in the Yorkshire Dales, Herdwicks in Cumbria and Scottish Blackfaces in Scotland.
Meat samples of lamb, hogget and mutton will be required from project participants and renumeration is being offered to cover sample postage and participation.
If you keep these breeds of sheep within these geographical locations and would be interested in being involved, please contact Anna Wilson, NSA Technical Communications Officer at [email protected]
Noble said, “This project will use UK native sheep breeds for the proof of concept. Being able to verify the origin and traceability of meat from these specialised niche breeds will create a more level playing field by enabling better prices for native sheep, which are often penalised in the mass market.”
Phil Stocker, NSA Chief Executive, added, “There’s potential for this technology to be used to verify food labelling particularly in the case of origin labelling, for which current analytical methods are too complex and expensive for official labs to use for enforcement. By combining digital end-to-end traceability of meat in the supply chain, with the chemical analysis of the meat acting as a confirmatory test enabling verification of the blockchain information if required, should help the industry promote premium breeds access markets and provide consumer confidence in where meat comes from.”
The project is working in partnership with Bia Analytical.
