"Is a difference between 2 products perceivable?"

V-G Sensory can give a well founded answer to this question thanks to:

• its performing panels
• Specific software for developing a correct and balanced test design
• Statistical tools for calculating the significance of differences
• Specialised infrastructure: test booths with daylight and red / green light filters: small colour differences between the products can be masked if advisable

Multiple applications of difference testing

• Switch over to another raw material
• Introduction of another machine
• Switch over to another production method
• Production on another location
• Change of packing material

-> does the consumer perceive any difference?
