Introduction. The degree of Dornic acidity (DA) is an indirect measure of milk contamination and quality. In freshly expressed milk, DA ranges between 1.0 and 4.0 (optimal). If DA is > 8.0 °D, it should be discarded. The correlation between DA in raw breast milk from internal donors (ID) and external donors (ED) based on storage time until pasteurization was assessed. Population and method. Retrospective, analytical study. Results. In 13 203 samples, DA was lower in IDs as of 14 days of storage: 2.92 (95% CI: 2.69-3.15) versus 4.01 (95% CI: 3.94-4.08), with a higher proportion of DA ≤ 4 °D (88% in IDs versus 76% in EDs); odds ratio: 2.30 (95% CI: 1.25-4.24). Conclusion. DA as of 14 days of storage was lower in IDs, with a higher prevalence of DA ≤ 4 °D. No correlation was observed between storage time and DA in ID samples.
简介。多尼克酸度（DA）的程度是衡量牛奶污染和质量的间接指标。在刚挤出的牛奶中，DA 值在 1.0 到 4.0（最佳）之间。如果 DA 值>8.0°D，则应丢弃。评估了基于储存时间直到巴氏消毒的内部供体（ID）和外部供体（ED）的初乳中 DA 的相关性。人群和方法。回顾性分析研究。结果。在 13203 个样本中，储存 14 天的 ID 中的 DA 较低：2.92（95%CI：2.69-3.15）与 4.01（95%CI：3.94-4.08），DA 值≤4°D 的比例较高（88%在 IDs 中，而在 EDs 中为 76%）；优势比：2.30（95%CI：1.25-4.24）。结论。储存 14 天时，ID 中的 DA 值较低，DA 值≤4°D 的比例较高。在 ID 样本中，未观察到储存时间与 DA 之间的相关性。
