Diaporama analyse sensorielle en anglais

  1. 1. CoSSOL Project Module 3 Third meeting in France Périgueux 11 th to 15 th May 2011
  2. 2. Organoleptic Analysis : Practical Exercise <ul><li>The test is based on two organoleptic exercises : </li></ul><ul><li>one on strawberries ; </li></ul><ul><li>another on Duck «foie gras» (fat liver ) </li></ul><ul><li>The use of mathematical probability laws will enable us to </li></ul>keep only one hypothesis . Objectives
  3. 3. <ul><li>The organoleptic tests involved 30 partners of the COSSOL project from 11 European countries. </li></ul><ul><li>This number of participants is enough to assess that 14 identical answers suffice to decide whether the test is successful or not with a small 5% error margin . </li></ul>Methodology
  4. 4. <ul><li>Test 1 : Tasting of strawberries </li></ul><ul><li>The triangular test with the binominal law enables us to know if the public can distinguish two different varieties of strawberries . </li></ul><ul><li>Test 2 : Tasting of «foie gras» </li></ul><ul><li>The Wilcoxon test method enables us to hiérarchise the taste of two regional products from the same category : « whole half-cooked foie gras» on the one hand, «portion of duck Foie Gras with chunks of liver » on the other . </li></ul>Experiments
  5. 5. <ul><li>Test 1 : The triangular test enabled the public to actually distinguish the two different varieties of strawberries . </li></ul><ul><li>Test 2: The Wilconxon test method enabled the public to hiérarchise the two different foie gras products according to their taste. </li></ul><ul><li>The «portion of duck Foie Gras with chunks of liver » was clearly preferred to the « whole half-cooked foie gras  » </li></ul>Results
  6. 6. <ul><li>Step 1 : The teacher provides tyhe class with the basic elements that need to be known . </li></ul><ul><li>Step 2 : The organoleptic analysis enables us to: </li></ul><ul><li>put the notions evoked previously into practice. </li></ul><ul><li>Ease their assimilation by the students ; </li></ul><ul><li>Understand tyhe meaning and the utility of these elements ; </li></ul><ul><li>Make a link between theory and practice. </li></ul>Carrying out the tests with a class
