The effect of microbial transglutaminase enzyme on some physicochemical and sensory properties of goat’s whey cheese

چکیده
The effect of the microbial transglutaminase (MTGase) enzyme treatment on some properties of whey cheese made from goat’s milk whey was studied; the results shows that the yield of whey cheese increased about 0.7 and 1.01% by using the concentration of 4 and 8U gm-1 whey protein respectively, the addition of MTGase for producing whey cheese caused a clear increase in hardness and the higher hardness was reached by using 8U gm-1 protein which represented 79gm cm-2 compared to untreated samples (34gm cm-2) after 7 days of storage at 4◦C. On the other hand, using this enzyme for producing whey cheese affect some sensory properties, bitterness and texture affected significantly (p≤0.05) while other properties (color, flavor, holes and consistency) not significantly affected.
