: Proteins are often categorized by their source—such as muscle, seafood, milk, and egg proteins—or by their solubility and chemical properties. 3. Functional Properties in Food Systems
: Understanding how heat, pH, or pressure changes a protein's structure, leading to effects like coagulation or loss of solubility.
The study begins with the chemistry of amino acids , the primary structural units of all proteins.
Proteins are complex macromolecules characterized by hierarchical levels of structure:
: The ability to form and stabilize emulsions (like mayonnaise) or foams (like meringue).
Compare this book to newer titles like Applied Food Protein Chemistry .
: How proteins interact with water, which affects texture and mouthfeel .
Studying these properties requires specialized laboratory methods:
