Abstract
The rheological properties of acidinduced coagulation of camel and cow milk gels following the addition of calcium chloride CaCl2 and hydrogen phosphate dehydrate Na2HPO42H2O were investigated using a dynamic low amplitude oscillatory rheology For a considered condition the final values of storage modulus G′ and loss modulus G″ of camel milk gels were significantly lower than those of cow milk gels The increase of the added CaCl2 levels improved significantly the gelation properties of camel and cow milk gels since a reduction in the gelation time and an increase in the gel firmness were observed Following the addition of Na2HPO42H2O at 10 and 20 mM no significant effect on the gelation rate and the firmness of camel milk gels was observed while a significant decrease in the gelation rate and firmness were observed for cow milk gels
