Análise sensorial da couve de folha crespa (kale) cultivadas em sistema convencional e hidropônico

Abstract

The objective of this work was to evaluate sensory characteristics of kale cultivated with organic fertilizers, control without fertilization and in a hydroponic system. The sensorial analysis of the plant at 60, 90 and 120 days was analyzed. The treatments were as follows: A = Kale without fertilization; C and E = with organic fertilizers and F = grown in a hydroponic system. It was found that for the sensory ordering tests, it was found that there was no significant difference between the treatments for the attributes aroma, sweet and bitter taste and crispness. There was a significant difference between the treatments for the color, and the color of the hydroponic kale showed the lighter green color. It was found that during the three tests, the evaluators maintained the same scores. As for the preference between kales, the panelists did not notice any difference, even at harvest 1, when the panelist indicated difference between the kale for the color attribute, where the kale in hydroponic system showed a lighter green color. The results of acceptance tests for kale for color, flavor, texture and overall impression showed no difference between treatments.
