What You Need to Know
The casein micelles in ricotta act as natural emulsifiers, with their surface charge optimal at pH 6.5–7.0. Controlled temperature and vigorous whisking disperse the liquid into fine droplets, while the casein stabilizes the interface. Excess heat or overwhisking disrupts micelle integrity, leading to denaturation and phase separation.
