Difference Between Fermentation Difference Between Fermentation and Curdlingand Curdling
FermentationFermentation - - sugars break down sugars break down into alcohol - into alcohol - maybe in the food maybe in the food or not (bread & or not (bread & cakes; beer & wine) cakes; beer & wine) normal pH normal pH conditionsconditions
CurdlingCurdling - proteins - proteins clumped into tight clumped into tight balls or bands balls or bands (clumps = curds) (clumps = curds) low pH created by low pH created by bacterial wastebacterial waste
