Abstract

RODRIGUES, Juliana da Silva Quintiliano et al. Sensory analysis of nectar of passion fruit cv. BRS Ouro Vermelho under different crop systems. Rev. Ceres [online]. 2013, vol.60, n.5, pp.595-602. ISSN 0034-737X.  https://doi.org/10.1590/S0034-737X2013000500001.

The objective of this study was to evaluate the sensory profile and acceptability of passion fruit nectar obtained from plants cultivated under different production systems: organic or conventional, with or without shading by intercropping with cassava. The samples were evaluated by Quantitative Descriptive Analysis and Acceptance Testing with hedonic scale. Data from the descriptive profile and acceptance were analyzed by External Preference Mapping, Analysis of Variance and the Fisher's LDS test. Fruits that were not subjected to shading produced nectars with very similar sensory profile and greater acceptance. Unshaded conventional and unshaded organic passion fruit nectars correlated with the attributes "green aroma", "homogeneity" and "sour taste". The greatest differences in acceptance were found between shaded conventional and unshaded organic samples for the attributes of color, flavor and overall quality. External preference mapping showed that the sample of nectar from shaded conventional passion fruit, with lower acceptance, was correlated with the attributes fibrousness and viscosity.

Keywords : passion fruit; organic production; acceptability; sensory profile; Passiflora edulis.
