摘要:

果实化渣性是评价柑橘品质的核心指标,直接影响消费者的接受度和商品价值。以12个柑橘品种为样本,通过感官评价与理化代谢分析等方法系统划分果实化渣性等级,以期构建高效的分级指标体系。招募60名消费者评价员,并遴选15名优选评价员培训后参试,经差别检验、快闪剖面分析等感官评价方法筛选得到“不化渣组”“适中化渣组”和“易化渣组”的甜橙和柚果实;结合代谢物分析发现果实囊瓣剪切力是甜橙化渣性的有效分级指标,随着化渣等级的提升,剪切力显著下降(P < 0.05),其中,甜橙“不化渣组”的剪切力为9 054.57 ~ 9 263.43 g,“适中化渣组”和“易化渣组”的剪切力则分别为5 996.83 ~ 6 873.17 g和2 030.08 ~ 2 669.92 g;果肉半纤维素含量可作为柚化渣性的分级指标,其含量随化渣等级提高显著降低(P < 0.05),其中,柚“不化渣组”“适中化渣组”和“易化渣组”的半纤维素含量分别为64.02 ~ 78.93、38.36 ~ 57.68和25.47 ~ 39.76 mg ∙ g-1 DW。次年重复验证显示,基于剪切力的甜橙化渣性分级准确率达84%,基于半纤维含量的柚化渣性分级准确率为80%。

Abstract:

The mastication quality of citrus fruit is the core index to evaluate its quality,which directly affects consumers acceptance and commodity value. In this study,12 citrus cultivars were used as samples to systematically classify the fruit mastication grade by sensory evaluation and physicochemical metabolism analysis,aiming to construct an efficient grading index system. After recruiting 60 consumer panelists and selecting 15 highly trained panelists following screening and training,the sweet orange and pomelo fruits were classified into three groups-‘difficult-mastication group’‘properly-mastication group’and‘easy-mastication group’-through sensory evaluation methods including difference tests and flash profile analysis. Combined with the analysis of metabolites,it was found that the shear force of fruit sac was an effective grading index of sweet orange mastication. With the increase of mastication grade,the shear force decreased significantly(P < 0.05). Among them,the shear force of‘difficult-mastication group’was 9 054.57-9 263.43 g,and the shear force of‘properly-mastication group’and‘easy-mastication group’were 5 996.83-6 873.17 g and 2 030.08-2 669.92 g,respectively. The content of hemicellulose in pulp can be used as a grading index of pomelo mastication,and its content decreased significantly with the increase of mastication grade(P < 0.05). Among them,the hemicellulose content of‘difficult-mastication group’was 64.02-78.93 mg · g-1 DW,the hemicellulose content of‘properly-mastication group’was 38.36-57.68 mg · g-1 DW,and the hemicellulose content of‘easy-mastication group’was 25.47-39.76 mg · g-1 DW. Repeated verification in the next year showed that the accuracy of sweet orange mastication grading based on shear force was 84%,and the accuracy of pomelo mastication grading based on hemicellulose content was 80%.
