When ZnSO4 or ZnCl2 at a level of 80 mmol/kg was incorporated,a coarser particulate network containing coagulated or precipitated proteins arranged in random clusters was developed(Fig. 4). This was due to the rapid coagulation and precipitation of proteins at high zinc concentration.This was associated with the poor gel property with low water holding capacity,as evidenced by very low breaking force and deformation along with very high expressible moisture content.Thus,the addition of zinc salts,especially ZnSO4, at 60 mmol/kg concentration resulted in the formation of fine and ordered filamentous gel network
(Fig. 4), thus improving gel strength and water holding capacity.
