Blending as a sample preparation protocol for mitigating intra- and inter-fruit heterogeneity in sensory analysis of sweetness and acidity in tomatoes
Tomato sensory analysis typically involves assessing different fruits, and the inherent intra- and inter-fruit variability poses experimental challenges.

| Résumé: | Tomato sensory analysis typically involves assessing different fruits, and the inherent intra- and inter-fruit variability poses experimental challenges. To address this, blending emerges as a sampling protocol to minimize panelist experimental error. This study delves into intra-(locule/pericarp) and inter-fruit heterogeneity, examining the efficacy of blended samples in assessing sweetness and acidity. Results reveal a higher acidity (22.2%) and sweetness perception (10.3%) in locular tissue, influenced by elevated titratable acids (TA) and soluble solids (TSS). The observed locular-to-fruit weight ratios (6-31%) might impact overall taste intensity. Fruit-to-fruit variation was high among the 16 varieties studied for TA, TSS, and dry matter. The use of blending to construct an "average" sample, increased sweetness (23%) and acidity perception (17%) without affecting sample ordering. Our results underscore the need to integrate locular relative weight into tomato phenotyping protocols and highlight the potential of blended samples in sensory analysis of traits related to the non-volatile fraction |
