Abstract

BACKGROUND

Mare milk has often been considered a food product with potential functional properties. However, the bioactive compound composition of mare milk, including vitamins and other minor bioactive compounds, as well as factors affecting this composition have scarcely been studied. Therefore, the present study aimed to characterize the changes during lactation in the content of water- and fat-soluble vitamins and total polyphenols, and the total antioxidant capacity of mare milk from semi-extensive farms. A total of 310 individual milk samples from 18 mares belonging to three commercial farms and 12 lactation times were analyzed. Ascorbic acid (vitamin C), thiamine (vitamin B₁), riboflavin (vitamin B₂), nicotinic acid and niacinamide (vitamins B₃), pantothenic acid (vitamin B₅), pyridoxal and pyridoxine (vitamins B₆), folic acid (vitamin B₉), cyanocobalamin (vitamin B₁₂), tocopherols and tocotrienols (vitamin E) and retinol and retinyl esters (vitamin A) were quantified using liquid chromatography. Total polyphenols and antioxidant capacity assays were analyzed using spectrophotometry.

RESULTS

The concentration of most bioactive compounds tended to decline as lactation progressed, with the exception of polyphenols and the total antioxidant capacity that oscillated during lactation. On the other hand, the effect of the different semi-extensive management of the farms was only significant for vitamin B₃ content.

CONCLUSION

To the best of our knowledge, the present study provides the most in-depth description of the vitamin profile of mare milk as well as new insights into polyphenol content and antioxidant capacity of mare milk. © 2024 The Author(s).

放牧母马乳汁中多种生物活性化合物在哺乳期的特征和变化监测。

背景：马奶通常被认为是一种具有潜在功能特性的食品。然而，有关母马乳中生物活性化合物（包括维生素和其他次要生物活性化合物）的组成以及影响这种组成的因素的研究却很少。因此，本研究旨在分析半集约化牧场的母马乳中水溶性和脂溶性维生素、总多酚含量以及总抗氧化能力在哺乳期的变化特征。我们分析了来自三个商业化牧场的 18 头母马和 12 个泌乳期的共 310 份牛奶样本。抗坏血酸（维生素 C）、硫胺素（维生素 B1）、核黄素（维生素 B2）、烟酸和烟酰胺（维生素 B3）、泛酸（维生素 B5）、吡哆醛和吡哆醇（维生素 B6）、采用液相色谱法对叶酸（维生素 B9）、氰钴胺（维生素 B12）、生育酚和生育三烯酚（维生素 E）以及视黄醇和视黄醇酯（维生素 A）进行定量。总多酚和抗氧化能力检测采用分光光度法进行分析：结果：随着泌乳期的延长，大多数生物活性化合物的浓度呈下降趋势，只有多酚和总抗氧化能力在泌乳期呈波动趋势。另一方面，农场不同的半集约化管理方式仅对维生素 B3 的含量有显著影响：据我们所知，本研究最深入地描述了母乳中的维生素含量，并对母乳中的多酚含量和抗氧化能力提出了新的见解。© 2024 作者姓名食品与农业科学杂志》由约翰威利父子有限公司代表化学工业学会出版。
