As shown in Table 2, the increase in time of US pretreatment produced a significant decrease in the k, which was related to the increase of WHC. In addition to these methods to characterize coagulation properties,the sensory evaluation could also be a good choice. The phenomena of coagulation for goat milk with different US pretreatment times is also shown in Fig. 4B with remarkable differences, which could confirm that the WHC of gels increase
with increasing US pretreatment time.
