TABLE 2 Effect of different solid colloid selections on microspheres
As can be seen from Table 2, the caviar microspheres prepared in comparative examples 1-3 were unstable in state and had cracking after sterilization. Analyzed: the product of comparative example 1, which is not added with the curdlan, is fragile after being sterilized with high brittleness, the product of comparative example 2, which is not added with the low-ester pectin, is easy to adhere, and the product of comparative example 3, which is not added with the gellan gum, is severely deformed. This demonstrates that the proportions of the four colloid components selected in examples 1-3 have an important effect in stabilizing the micro-sphere state of the caviar, and in having good elasticity, and being not easy to crack at high temperature.
