physical properties
The results ( table l ) revealed that the components in corn milk alone could not produce a product with a curd structure of yogurt. thus, the physical properties of corn milk yogurt without additon of milk protein are not presented. However, corn milk could support the growth of S. thmophilus and L.delbrueckii subsp. bulgaricus as indicated by the reduction of PH (fig 2 ). in the corn milk yogurt were 6.07+0.08% and 1.09+0.07% respectively (fig 1),which were lower than in cow milk yohurt. the important proteins in corn milk were zein (prolamins) and corn glutein (pomeranz, 1987; Lasztity,1996) that cannot from agel in the acid conditions of yogurt.
