A paper published in Comprehensive Reviews in Food Science & Food Safety explored the physicochemical and nutritional characteristics of sheep's milk and development of sheep's milk dairy products containing prebiotics and/or probiotics.

According to the authors, cow's milk is the most commonly consumed milk, dominating global milk production with 782 million tons in 2013. Furthermore, 85% of the world's milk production is derived from cattle, followed by milk from species such as buffalo (11%), goats (2.3%), sheep (1.4%) and camels (0.2%).

However, milk-producing sheep farms represent a significant part of the agrarian economies in many countries, especially those bordering the Mediterranean Sea and in the Middle East.

Sheep's milk is an excellent source of nutrients and is mainly used for cheese production due to its high total solids content, contributing to a high cheese yield. However, the functional benefits of this food matrix remain unexplored by the dairy industry.

“Sheep milk has many (functional) qualities that need to be explored. It’s much more than a simple delicatessen to produce fine cheeses,” Celso Fasura Balthazar, lead author of the paper, explained.

More studies are needed to investigate the effects of the addition of probiotic microorganisms and, especially, prebiotic components in sheep dairy products such as cheese, yogurt, ice cream and other dairy desserts.
