Abstract

Rapeseed (Brassica napus L.) is the second largest globally cultivated oil crop, but the effects of post-harvested ripening on rapeseed quality is unclear and unpredictable. This study reveals the relationship between post-harvest ripening periods (PHR) and physicochemical quality of different rapeseed cultivars using comprehensive physicochemical indicators analysis. The results indicate that PHR led to a gradual decrease in chlorophyll, carotenoid and moisture content but continually increased oil and total phenol content (TPC). Besides, 295 lipid molecules from 13 lipid subclasses were identified, revealing that the relative content of triacylglycerol (TG) was progressively increased while diacylglycerol (DG) demonstrated a consistent decline throughout the PHR. Correlation analysis, hierarchical cluster analysis (HCA) and principal component analysis (PCA) were employed to construct and verify the comprehensive quality evaluation model for rapeseeds in PHR. This paper develops a comprehensive quality evaluation model for post-harvest ripening rapeseeds and advances the development of agricultural products.

收获后成熟油菜籽的综合理化指标分析和质量评价模型构建。
油菜籽(Brassica napus L.)是全球第二大油料作物,但收获后成熟对油菜籽品质的影响尚不明确,也无法预测。本研究通过综合理化指标分析,揭示了不同油菜品种收获后成熟期(PHR)与理化品质之间的关系。结果表明,收获后成熟期导致叶绿素、类胡萝卜素和水分含量逐渐下降,但油分和总酚含量(TPC)持续上升。此外,还鉴定了 13 个脂质亚类中的 295 个脂质分子,发现三酰甘油(TG)的相对含量逐渐增加,而二酰基甘油(DG)在整个 PHR 期间持续下降。采用相关分析、层次聚类分析(HCA)和主成分分析(PCA)构建并验证了 PHR 中油菜籽的综合质量评价模型。本文建立了收获后成熟油菜籽的综合质量评价模型,推动了农产品的发展。
