Food traceability is the most important point in food industry. We publish some withdrawing news in our website. If a factory have traceability system, it will be more easier for them to recall the product when they have a problem. According to European Food Safety Authority (EFSA), traceability is keeping food products under observation during buying raw material, production and distribution , examining production chain and finding solutions for food and animal feed origin problems European Union rules entail traceability since 2005.
The most common systems used for traceability are barcode and Radio Frequency Identification (RFID) systems. Barcode system is a product identification system that includes digital or alpha digital sequences.
RFID system is automatic identification system that uses radio waves and includes a reader and a microchip ( there is a antenna around microchip).
For food RFID system, it works on 13,56 MHz band. The most important reason to choose this band is; its acclimatizing of flexible food labels. Also this band is not be influenced by humidity.
The properties that RFID label must include are as below;
- Distant read aperture
- High reading speed
- Resistance of dirty surfaces
- High memory
- Reading and writing function
Advantages of RFID System In Food Industry
- Reducing labor cost. It is easy to apply during storage and can be read by hand.
- RFID readers can read several labels in the same time easily and fast.
- Preventing economical looses.
- Supplying more effective traceability and control during production chain.
- Increasing consumer behaviour information. It is especially important for new products.
- Making easy to control easy to spoil products.
- Solving quality problems.
- Making easy recalling products and increasing consumer trust.
RFID system is not preferred commonly due to its economical cost today. But its advantages will make it the most used identification system in the future.
