- Difference from reference test: this test was developed on the
basis of the Difference from Control test (Meilgaard, Civille, &
Carr, 1999, chap. 6.8). This method was used to compare the
sterilized sauces with the fresh sauces. For this test, at least 20
untrained panelists were used. Each sterilized sauce samplewas
compared to its fresh reference, based on a 5 level descriptor
scale (no difference, slight difference, average difference, large
difference, very large difference). To evaluate the panelist's
correct assessment, a sample of fresh sauce (hidden) was also
compared to the fresh reference.
