A new objective texture test method was developed and compared with the
goose liver manual grading system. The whole fatty goose livers were purchased
from Bábolna Holdings and were examined at two stages: in the preliminary test
three times 3 pieces were taken, while in the main test five times 22 pieces.
All of them were examined both at a pre-cooled stage and after a 24-hour
storage on ice. The texture analyses were made by QTS 25 texture test system
immediately after the manual grading. A special probe with three needles was
developed for the Texture Analyser. Most of the texture parameters correlated
significantly with the liver grades, as shown by statistical evaluation of the
data. The best quality assessment was made by a binary equation where the hardness
value and the mass of the product were the independent variables.
