Abstract

The sensory quality (SQ) of pumpkin fruit is one of the most important quality indexes for consumers. In this study, a rapid pumpkin SQ evaluation method based on near-infrared spectroscopy (NIRS) was introduced. The starch and moisture contents of pumpkins were first determined by NIRS, and then the SQ of pumpkin could be estimated indirectly by these components. Test was carried out on 97 samples of 34 pumpkin fruits. The pumpkin starch and water NIRS models based on variable dimension particle swarm optimization combined moving window (VDPSO-CMW) and standard normal variate transformation (SNV) showed the best predictive performances, whose predictive determination coefficients (R²_p) were 0.775 and 0.932, respectively. A multiple linear regression model (correlation coefficient = 0.788) was established based on the prediction results of the two models and the SQ values obtained from cooking experiments. The proposed method has the potential to provide effective support for pumpkin breeding and production.

基于近红外光谱的南瓜感官质量快速评价方法

对消费者来说，南瓜果实的感官质量（SQ）是最重要的质量指标之一。本研究引入了一种基于近红外光谱（NIRS）的南瓜感官品质快速评价方法。首先利用近红外光谱测定南瓜的淀粉和水分含量，然后通过这些成分间接估算南瓜的品质。对 34 个南瓜果实的 97 个样品进行了测试。基于变维粒子群优化组合移动窗口（VDPSO-CMW）和标准正态变分变换（SNV）的南瓜淀粉和水分近红外光谱模型显示出最佳的预测性能，其预测判定系数（R2p）分别为 0.775 和 0.932。根据两个模型的预测结果和烹饪实验获得的 SQ 值，建立了多元线性回归模型（相关系数 = 0.788）。所提出的方法有望为南瓜育种和生产提供有效支持。
