The percepcion of organoleptic quality of the carrot depends variety and location of production

Through three years of testing, 2010-2012, the sensory variability of carrot was investigated. The quality assessment is based on descriptive sensory quantitative analysis and measurements of sugars and firmness. The sensory space built on many batches from the various types of carrot and two production areas is characterized by a first axis opposing products perceived sweeter to products perceived bitter, pungent with a ?chemical? aroma and by a second axis based on texture with juicier products opposed to firmer products with remains in the mouth. In this space, an overall global aroma criterion associated with a high level of sugar characterizes consumer-preferred products (Cottet et al. Cf presentation on consumer preferences). Meanwhile some batches are measured cooked (steaming). The sensory space of cooked carrots is strongly determined by the criteria of texture that oppose firm products to those appreciated as melting. Despite a cooking protocol taking into account the size of carrots, it is difficult to distinguish the varietal characteristics effect from the cooking factor. For the other criteria of the cooked product, the sweetness perception opposed to the bitter one is more discriminating than the aroma criteria. The various types of carrot are distributed throughout the sensory space. However, the location and year of production are important factors in the expression of varieties quality criteria. The varietal choice appears dominant, and in this work model varieties have been identified; they either have a low variability, or an aromatic or sweet expression influenced by the environment.? ? ? ? ? ? ? ? ? ? ? ? ?? ? ?
