Description
Acid-assisted extraction of minerals and collagen from bones through controlled hydrolysis.
Technical
Acetic acid protonates calcium phosphate in bones, converting hydroxyapatite to more soluble calcium acetate while breaking collagen triple helices into gelatin polypeptides.
Culinary Significance
Fundamental for nutrient-rich stocks and emulsified sauces where both mineral content and viscosity are desired.
