刺梨鲜果营养成分检测数据集合

数据采集遵循“品种-产区-成熟度”三维分层抽样规则，每个品种、产区及成熟度组合选取35个以上样本，确保样本代表性；检测过程采用平行样三重测定法，每组样本重复检测3次，取平均值作为最终数据，通过格拉布斯准则剔除异常值，降低检测误差。数据处理阶段运用描述性统计明确各营养指标的分布特征与核心区间，通过相关性分析算法挖掘种植环境、成熟度与营养成分的关联规律，采用聚类分析对不同来源鲜果进行营养特征分类，数据误差控制在2%以内，经多实验室交叉验证与实地复现，确保结果准确可靠。

Data collection follows a three-dimensional stratified sampling rule based on the dimensions of variety, origin and maturity. No fewer than 35 samples are selected for each combination of variety, origin and maturity to ensure sample representativeness. The detection process adopts the triplicate parallel determination method: each sample group is tested three times repeatedly, and the average value is taken as the final data. Abnormal values are eliminated via Grubbs' test to reduce detection errors. In the data processing stage, descriptive statistics are utilized to clarify the distribution characteristics and core intervals of each nutritional indicator; correlation analysis algorithms are employed to uncover the correlational patterns between planting environment, maturity and nutrient components; cluster analysis is applied to categorize the nutritional profiles of fresh fruits from different sources. The data error is controlled within 2%, and cross-validation across multiple laboratories and field reproduction are conducted to guarantee the accuracy and reliability of the final outcomes.
