Abstract:

In this study, 22 fresh faba bean germplasm resources were used to evaluate and analyze the edible quality traits of different varieties by quantitative description analysis. A vocabulary for quantitative description of the sensory characteristics of fresh faba beans was established. Multivariate statistical analysis methods such as principal component analysis, correlation analysis, and analysis of variance were used to explore the correlation and differences within these sensory traits. Key traits affecting sensory quality and the scoring criteria of the taste sensation were preliminarily determined. The results showed that there were significant (P<0.05) differences in sweetness, hardness, and waxiness among the 22 fresh faba bean germplasm resources. The overall evaluation of fresh faba beans was significantly (P<0.01) positively correlated with sweetness and umami, and the correlation coefficients were 0.92 and 0.91, respectively. Sweetness, umami, hardness, and waxiness were selected as the key traits for the sensory evaluation of fresh faba beans. The varieties with the best sensory quality (Y019, HN002) and the worst sensory quality (GB37, Qilichangxiang) were selected to grade the sensory quality of the taste. The scoring criteria for good taste were as follows: sweetness≥8.0, umami ≥6.5, soft texture(hardness ≤2.5, waxiness ≥7.5) or tender and crisp texture(4.5≤ hardness ≤7.0, waxiness ≤2.0). The poor palatability was scored as follows: sweetness ≤4.5, umami≤3.5, hard texture (hardness ≥7.0, waxiness ≤2.0), or loose texture (hardness ≤4.5, waxiness ≤2.0). The experimental results provided theoretical basis for the in-depth study of the sensory quality in fresh faba beans, and technical support for the selection and breeding of high-quality fresh faba beans.
