With development of modern food industry, plant-based milk products are widely used to replace dairy products to cook different kinds of food. Due to different origins, it is necessary to assess the nutrition difference between dairy and plant-based milk products. Phospholipids and unsaturated fatty acids, as the important nutrients in cream and butter, were closely related to body development and health. This study developed a rapid determination of phospholipids and double bonds in creams and butters based on P NMR and H NMR for nutritional difference assessment. Unsupervised principal component analysis and supervised orthogonal least squares discriminant analysis showed marked differences between dairy and plant-based milk products. Eight compounds were screened by variable importance in projection, fold change and P-value. Furthermore, two biomarkers (phosphatidylserine and phosphatidylethanolamine) were identified to distinguish dairy and plant-based milk products. The study demonstrated that P NMR has great potential for rapidly distinguishing milk origins.
随着现代食品工业的发展，植物基奶制品被广泛用于替代奶制品来烹饪各类食物。由于来源不同，有必要评估奶制品和植物基奶制品之间的营养差异。磷脂和不饱和脂肪酸作为奶油和黄油中的重要营养素，与身体发育和健康密切相关。本研究基于磷核磁共振（P NMR）和氢核磁共振（H NMR）开发了一种快速测定奶油和黄油中磷脂和双键的方法，用于营养差异评估。无监督主成分分析和有监督正交最小二乘判别分析表明，奶制品和植物基奶制品之间存在显著差异。通过投影变量重要性、变化倍数和P值筛选出8种化合物。此外，还鉴定出两种生物标志物（磷脂酰丝氨酸和磷脂酰乙醇胺）以区分奶制品和植物基奶制品。该研究表明，磷核磁共振在快速区分牛奶来源方面具有巨大潜力。
