摘要: 为正确评价鲜食百香果的品质,以广西和福建的百香果果实为试材,测定果实品质相关指标,通过变异分析、相关性分析及主成分分析筛选核心指标,在此基础上运用层次分析法确定指标权重,最后采用灰色关联度法建立鲜食百香果品质综合评价模型,并结合感官审评进行验证分析。结果表明:单果质量、可食率、糖酸比、总黄酮含量为鲜食百香果品质评价的核心指标;鲜食百香果品质综合评价模型:百香果品种(系)的加权灰色关联度=单果质量×0.418 1+可食率×0.222 6+糖酸比×0.249 7+总黄酮含量×0.109 6。感官评审结果与综合评价模型得分结果拟合度达0.97,表明建立的鲜食百香果品质综合评价模型可为鲜食百香果果实品质综合评价提供科学依据。

Abstract: In order to correctly evaluate the quality of fresh passion fruit, quality indicators of passion fruit from Guangxi and Fujian provinces were determined and the core indicators were identified by variation analysis, correlation analysis and principal component analysis. Subsequently, the weights of these indicators were determined by the analytic hierarchy process to establish a comprehensive evaluation model for the quality of fresh passion fruit by grey relational analysis. The model was validated by comparison with sensory evaluation. The results showed that single fruit mass (X1), the proportion of edible parts (X2), sugar-acid ratio (X3) and total flavonoids content (X4) were the core indexes for quality evaluation of fresh passion fruit. The established model was described as follows: the weighted gray correlation degree of passion fruit varieties (lines) = 0.418 1 X1 + 0.222 6 X2 + 0.249 7 X3 + 0.109 6 X4. A comparison of the sensory evaluation results with the model prediction values showed a correlation coefficient of 0.97, indicating that the model will provide a scientific basis for comprehensive quality evaluation of fresh passion fruit.
