Effects of Ca2+ Concentration on Calcium Carbonate Crystallization in Egg White Protein Solution
The calcium carbonate crystallization were controlled by Ca2+ concentration in the 10% (V/V) egg white protein solution and the morphology, structure and thermal decomposition of which were characterized by FT-IR, SEM, XRD and TG. The results showed in egg white protein solution system, concentration of Ca2+ had significant effects on the crystallized morphology, orientation and crystallinity of calcium carbonate. Calcium carbonate particles have more uniformed calcite and vaterite mixed crystallization in low Ca2+ concentration while calcium carbonate tends to form mixed particle sizes and more complete calcite crystallization in high Ca2+ concentration.
