| The experimental work proposed has tested the use of some pre-treatments to optimize the dehydration of biological carrots (var. Romance) The pre-treatments used were: 1) blanching (95°C) for 1.5 min, 2) blanching (70°) with citric acid 2% (w/v) for 2 min, 3) dipping in pectin’s 1% (w/v) for 1 min, 4) dipping in pectin’s 1% (w/v) with vacuum impregnation technology for 10 sec at 734 mbar. The aim of this work was to evaluate and compare the effects on carrot quality attributes. For this goal, the trial involved the use of various analytical techniques such as the enzyme activity test for peroxidase (POD), colorimetric analysis, determination of the total phenol content, extraction and quantification of carotenoids, rehydration process analysis.
