江西省典型产区南酸枣的果实品质分析及感官评价

Analysis of Fruit Quality and Sensory Evaluation of Choerospondias axillaris from Typical Production Areas in Jiangxi Province

  • 摘要: 受遗传、气候环境及地理位置等因素影响,不同产地的南酸枣果实品质存在明显差异。为了筛选果用南酸枣优良种源,以江西省5个典型产区的300份南酸枣果实为试验材料,从果实的表型性状、色泽、质地、矿质元素含量及感官评价等方面对其开展系统分析,明确南酸枣种质资源、质构特性与矿质元素含量之间的关系。结果表明:上饶市余干县和赣州市赣县的南酸枣果形均匀,变异系数分别为3.05%、3.33%;赣州市赣县和萍乡市上栗县南酸枣的果肉黏性较高,赣州市崇义县南酸枣的果肉黏性适中,为-0.47 N;赣州市崇义县、宜春市万载县和上饶市余干县南酸枣的果肉内聚性高,宜春市万载县南酸枣果肉的硬度和弹性最高,分别为2.01 N、0.42 mm;宜春市万载县和上饶市余干县南酸枣果肉的咀嚼性和断裂力更高;上饶市余干县南酸枣果实中Mg、K和Zn的含量明显高于其他产区;赣州市赣县和宜春市万载县南酸枣的感官评分显著高于其他产区,分别为76.68、70.65分。本研究结论可为南酸枣果用品种选育及其开发利用提供技术支撑。

     

    Abstract: Due to the influences of factors such as genetics, climate, environment and geographical location, there are obvious variations in the quality of Choerospondias axillaris fruits from different origins. To screen out superior provenances of fruit-used Choerospondias axillaris, we collected 300 samples of Choerospondias axillaris fruits from five typical production areas in Jiangxi Province. Subsequently, the fruit phenotypes, color, texture, mineral element contents and sensory evaluation were systematically analyzed, and the relationship among germplasm resources, texture characteristics and mineral element content of Choerospondias axillaris were clarified. The results showed that the fruit shapes of Choerospondias axillaris from Yugan County, Shangrao City, and Ganxian District, Ganzhou City were uniform. The coefficients of variation were 3.05% and 3.33% respectively. The pulp of Choerospondias axillaris from Ganxian District, Ganzhou City, and Shangli County, Pingxiang City had high viscosity, with a value of-0.47 N. The pulp of Choerospondias axillaris from Chongyi County, Ganzhou City, Wanzai County, Yichun City, and Yugan County, Shangrao City had high cohesiveness. The pulp of Choerospondias axillaris from Wanzai County, Yichun City had the highest hardness and elasticity, which were 2.01 N and 0.42 mm respectively. The chewiness and fracture force of the pulp from Wanzai County, Yichun City and Yugan County, Shangrao City were higher. The contents of mineral elements Mg, K, and Zn in the fruits of Choerospondias axillaris from Yugan County, Shangrao City were significantly higher than those in the fruits from the other four production areas. The sensory scores of fruits from Ganxian District, Ganzhou City, and Wanzai County, Yichun City were significantly higher than those of other production areas, reaching 76.68 and 70.65 points respectively. The research findings can provide technical support for the breeding, development and utilization of fruitused Choerospondias axillaris varieties.
