A state-of-art review on camel milk proteins as an emerging source of bioactive peptides with diverse nutraceutical properties

The generation of camel milk derived bioactive peptides (CM-BAPs) have started to grab keen interest of many researchers during the past decade. CM-BAPs have shown more significant bioactive properties in comparison to camel milk intact proteins. CM-BAPs can be obtained using enzyme hydrolysis to form hydrolysates, or by the fermentation process. In this systematic review, 46 research articles exploring the health-related bioactive properties of CM-BAPs through in-vitro and in-vivo studies have been included. CM-BAPs have been reported for their antioxidant, anti-diabetic, anti-obesity, antihypertensive, antibacterial, antibiofilm, anticancer, anti-inflammatory, anti-haemolytic, and anti-hyperpigmentation activities. The effects of factors such as molecular weight of peptides, type of enzyme, enzyme to substrate ratio, hydrolysis temperature and duration have been analysed. The in-vitro studies have provided enough evidence on certain aspects of the pharmacological actives of camel milk bioactive peptides. Nevertheless, the in-vivo studies are very limited, and no clinical studies on CM-BAPs have been reported.
