21
Categories of Sensory Analysis Tests

• Preference Tests
• Difference Tests
• Descriptive Tests

22
Aim of Triangle Test

• The Triangle Test is used to find out
• if there is a detectable difference
• between two similar products

23
Triangle Test

• Tester is presented with three coded samples
• Two samples are the same, one is different
• Tester is required to identify the sample that is
  different
