ESTIIC-Project CABRFID
Cabrales Cheese Traceability based on RFID
technologies
http//www.estiic.org
http//www.nrw.de
Project Partners University of Dortmund,
Department of Logistics (FLog),
GERMANY Laboratoria Interprofesional Lechero de
Asturias (LILA), SPAIN Project Duration July
2006 December 2007 Goal Evaluate the possible
use of RFID for the documentation of each
production step of Cabrales Cheese
7
Current Problems and Issues

• European Union
• Law aims at tracking tracing (EU regulations
  no. 178/2002, 1935/2004)
• Control of food quality and safety
• Farmer
• Limited space inside the ripening caves
• Profit vs. Restrictions
• Controller
• Proof of origin
• Authenticity control
• Customer
• Food Safety
• Transparency of the Supply Chain

8
Cabrales Cheese

• Blue Cheese with penicillium molds
• 3 Sorts of Milk Cow, Sheep, Goat
• Stays up to 6 months in ripening caves
• Customers pay up to 30 EUR / kg
• Completely handmade
• Small production lots
• Local delicacy in Asturias, rarely available in
  other areas

9
Requirements for using RFID with Cabrales Cheese

• Tagging the cheese from the very beginning
• Raw milk (more or less liquid) in a bowl
• Withstand the cave conditions
• Withstand the acid ripening process
• No chemical alteration of the cheese allowed
• Tags should be reusable
• Low reading distance
• No bulk reading wanted
• High memory capacity of the tag
• Every production step is to be stored in addition
  to the cheese's specific data

10
Software requirements

• Protection against manipulation
• Changing dates of production steps
• Changing cheese composition data
• Simple usage
• Farmer's don't want to study manuals
• Available for different operating systems
• E.g. .NET Application
• Multilingual
• English
• Spanish
• German

11
Hardware requirements

• Reading / Writing must be done with a handheld
  device
• No electrical power in some caves
• Each cheese is manually handled
• The handheld device must be resistant against the
  cave conditions
• 100 humidity
• Must survive falling on the cave's floor
• RFID Reader should be in Compact Flash format
• Increased flexibility
• Independent from specific handheld computers

12
Software solution (Prototype)

• Developed in C
• About four thousand lines of code
• Application takes 125 KB of memory space on the
  mobile device in addition to the necessary .NET
  framework

Final Application
RFID-Tag, Anchor Clamp
15
Chosen transponder type

• ITG Assa Abloy IN TAG 200
• HITAG S Chipset
• 2048 Bytes of memory
• About 5 cm reading distance
• 125 kHz frequency
• Material PA6 modified, food compatible
• Chemical protection class IP68

16
The RFID-enhanced production process

• An RFID-tag is attached to each cheese from the
  very beginning
• Lot number
• Serial number
• Composition
• Manufacturer / Farmer's ID
• The data is read and updated for each step
• Production day
• Shelf
• Cave in / cave out
• Drying Room
• Packaging
• Each RFID-tag is removed during packaging, and
  the data is stored into a central database
• The serial number is printed on the packaging

17

• Removal of transponder
• Data stored in central Database

• Labelling by a transponder
• Printed lot number on the tag

• Identification point
• All Data locally saved on the transponder chip

18
Summary of the developed solution

• Requirements of the EU are fulfilled
• Tracking Tracing of each individual cheese is
  possible
• Food safety is enhanced
• Running costs are very low because the tags and
  plastic application parts are reused
• Due to a low reading distance and the
  restrictions in the software the complete
  procedure is process-safe
• The customer gets the chance to retrieve detailed
  information about the cheese he bought without a
  necessary knowledge about RFID technology

19
RFID is on everyone's mind

• The future technology RFID is already deep-seated
  in the present.
• Wireless chips connect the physical world of
  products to the virtual world of digital data.
• Inefficiencies in value creation and efforts
  about inner security are driving the demand for
  wireless chips.
• RFID stands for an all-embracing structural
  concept in the economy, which is getting far
  beyond the regime change away from the barcode .
• RFID-Systems will continue to rapidly gain
  importance.
