Special Issue Information

Dear Colleagues,

The production of sheep and goat milk is an important segment of agricultural production, valued for its nutritional and health properties. Milk production using sheep and goats has a long tradition in many regions of the world, especially in Mediterranean countries. Given the increasing demand for high-quality and safe milk and dairy products, it is necessary to optimize production processes and improve the quality standards and safety of sheep and goat milk. This Special Issue invites research that seeks to optimize sheep and goat milk production, improve milk quality, and ensure milk safety. Additionally, this Special Issue will address sustainable practices in small ruminant dairy farming, ensuring both environmental responsibility and animal welfare. Therefore, the aim of this Special Issue is to cover a wide range of topics, including advances in genetic selection, nutrition, husbandry techniques, and health and biosecurity measures in milk production, which contribute to the optimization of milk production and in improving the nutritional composition and hygiene and safety standards of sheep and goat milk. Connecting these aspects is essential for a sustainable form of production that responds to growing market needs. We invite researchers to submit research papers and scientific reviews that explore how genetic selection, feeding strategies, farm management, disease control, biosecurity, and environmental factors influence the yield, quality, and safety of sheep and goat milk.

Milk adulteration is a common form of food fraud, particularly in high-value dairy products from small ruminants. A frequent practice involves dilution with water, often combined with the addition of sugars to mask physicochemical changes and avoid detection during routine quality control. This study aimed to develop an analytical approach for detecting combined adulteration in goat and sheep milk involving both water dilution and sucrose addition. Controlled experiments were conducted by diluting milk samples with water (1–15%) followed by the addition of sucrose solutions. Changes in physicochemical parameters, including fat, protein, total solids, lactose, density, freezing point depression, mineral content, and pH, were evaluated using an automated milk analyzer. In parallel, a suspected adulterant powder was characterized using conventional chemical analysis, ICP-AES, and HPLC-RI, revealing a composition predominantly of sucrose (91.4% w/w) with elevated sodium levels. Sucrose in milk samples was subsequently quantified using an enzymatic spectrophotometric method. Water dilution reduced protein, total solids, and density, while sucrose addition partially restored these parameters, masking adulteration effects. However, sucrose was reliably detected at concentrations above 0.1%. The proposed workflow may provide a practical and cost-effective complementary tool for routine dairy authenticity surveillance and fraud prevention. Full article
