Increased consumption of cheese combined with a shortage of rennet has led to a global interest for natural milk coagulants from some other sources different from animal sources such as plant and microbial sources. In this study, the effect of ginger extract in comparison to calf rennet on physicochemical, textural profiles, rheological and sensory properties of whey-less cheese was examined. The results showed that the proteolytic activity and milk-clotting activity of ginger extract used in this study were 134.26 units and 326.55 units/mg respectively, and the milk-clotting activity/ proteolytic activity ratio was about 2.43. This can be desirable for cheese processing. This can be desirable for cheese processing. Also, dry matter and protein content of cheese produced by ginger extract were significantly lower and the fat in dry matter was higher than samples made using rennet (p <0.05). But the coagulant type had no significant effect on the acidity, pH and salt content of the samples (P> 0.05). Hardness, springiness, gumminess, chewiness, storage modulus, loss modulus and complex viscosity of cheese samples prepared by ginger extract were significantly lower than cheese prepared by rennet (p <0.05). The overall acceptability score of cheeses produced by ginger extract was not significantly different from the samples of cheeses prepared with calf rennet. The flavor and texture score of samples prepared by ginger extract was significantly higher than cheese prepared by calf rennet. According to the results obtained of this study, ginger extract can be used as a coagulant in the preparation of whey-less cheese.
