摘要：为综合评价香榧营养品质,本试验以浙江省8个不同地区共32份香榧生籽样品为研究对象,对包括宏量营养素、矿质元素及维生素E在内的38项营养品质指标含量进行差异性分析及相关性分析,建立模糊数学综合评价模型以评价其营养品质。结果表明,不同地区香榧营养品质指标含量存在一定差异,宏量营养素中可溶性糖与淀粉的变异系数相对较大,微量营养素中钠的变异系数最大。相关性分析结果表明,脂肪与蛋白质、淀粉间存在较强的负相关,多数氨基酸间表现为极强的正相关,亚油酸与金松酸、硬脂酸与油酸两组脂肪酸在组内具有较强的正相关,组间表现为较强负相关。模糊数学综合评价结果显示磐安县、东阳市与诸暨市3个地区宏量营养素指标评分较高;微量营养素评分较高的为柯桥区、嵊州市与松阳县,整体综合评分在0.403~0.528之间。本研究结果为香榧营养品质评价及产品分级利用提供了研究基础与参考依据。
In order to comprehensively evaluate the nutritional quality of Torreya grandis, 32 samples of Torreya grandis seeds from 8 different areas in Zhejiang Province were taken as the research objects. The differences and correlations of 38 nutritional indexes including macronutrients, mineral elements and vitamin E were analyzed, and the fuzzy mathematics comprehensive evaluation model was established to evaluate its nutritional quality. The results showed that: there were some differences in the nutritional quality of Torreya grandis in different regions. The coefficient of variation of soluble sugar and starch in macronutrients was relatively large, and the coefficient of variation of Na in micronutrients was the largest. The results of correlation analysis showed that there was a strong negative correlation between fat and proteins, as well as between starchs. And a strong positive correlation between most amino acids. Linoleic acid and ginaric acid, stearic acid and oleic acid had a strong positive correlation within the group, respectively, and a strong negative correlation between the groups. The results of fuzzy mathematics comprehensive evaluation showed that Pan’an County, Dongyang City and Zhuji City had higher macro nutrient index scores;samples Keqiao District, Shengzhou City and Songyang County had higher micronutrient index scores, and the overall comprehensive score was between 0.403 and 0.528. The results provide a basis for the evaluation of nutritional quality and product classification of Torreya grandis.
