Abstract

Donkey milk is acknowledged as a valuable nutritional source in the human diet, well known for its bioactive and functional properties. Therefore, the main goal of this research was to investigate the similarities between donkey and human milk after six months of lactation with respect to the lipid composition, milk fat globule particle size distribution, antioxidant activity, and mineral content. These components are related to the nutritional properties of milk and they are important for the dairy industry as well to human health. The obtained results showed that the most dominant fatty acids in both types of milk were oleic, palmitic, and linoleic followed by lauric, capric, and alpha-linolenic acids. Donkey milk had a desirable fatty acid composition due to its high alpha-linolenic acid content and especially low omega-6/omega-3 ratio. After the fat globule distribution was analysed, it was found that fat globules smaller than 2 μm had the highest percentage in both human and donkey milk. The antioxidant activity of human milk was significantly higher at 42.95% compared to donkey milk at 35.83%. Predominant mineral in both types of milk was Ca, followed by P, Zn, Fe and Cu. Highlighting the similarity between donkey milk and human milk encourages the use of donkey milk as a potential substitute for human milk in the future.

驴和母乳泌乳6个月后营养质量和脂肪球大小的比较

驴奶被公认为人类饮食中有价值的营养来源，以其生物活性和功能性而闻名。因此，本研究的主要目的是调查泌乳六个月后驴和母乳在脂质成分、乳脂球粒径分布、抗氧化活性和矿物质含量方面的相似性。这些成分与牛奶的营养特性有关，对乳制品工业和人类健康都很重要。结果表明，这两种牛奶中最主要的脂肪酸是油酸、棕榈酸和亚油酸，其次是月桂酸、癸酸和α-亚麻酸。驴奶由于其高α-亚麻酸含量，特别是低ω-6/ω-3比例，具有理想的脂肪酸组成。在分析脂肪球分布后，发现小于2μm的脂肪球在母乳和驴奶中的百分比最高。母乳的抗氧化活性为42.95%，明显高于驴奶的35.83%。这两种牛奶中的主要矿物质是Ca，其次是P、Zn、Fe和Cu。强调驴奶和母乳之间的相似性有助于驴奶在未来成为母乳的潜在替代品。

期刊介绍： Mljekarstvo is an open access, peer-reviewed international quarterly scientific journal. The first issue was published in 1951, by the Croatian Dairy Operators'' Association (today: Croatian Dairy Union, publisher). In a paper at a Union conference held 28 October 1951 in Zagreb it was said: "Our desire is that this magazine does not meet the fate of its predecessors, but that it continues to reflect the creative efforts and to provide guidelines for the producers as well as all other operators employed in the dairy industry." It is our pleasure today to say that wishes of the enthusiasts who attended the conference have come true, and the magazine Mljekarstvo during the last six decades was a reflection of the creative efforts of numerous dairy scientists and experts, and through its texts it served as a guideline in improving production and processing of milk and dairy products. Mljekarstvo has been following all the achievements of the dairy profession in Croatia, and it also gives the short surveys of world achievements. The result of the research of local and foreign scientists and experts always find their place in the magazine Mljekarstvo. It has been edited by our outstanding dairy experts employed at colleges, research institutions and dairy companies.
