Preparation And Characterization Of Acid-Induced Gels At Ph 1.0-4.0 And Thermal-Stable Dispersions At Ph 5.5-6.0 Using Preheated Whey Protein, Kangkang Li
Masters Theses
Whey protein (WP) is a good source for producing protein-rich products, including satiety foods and beverages. Thermal aggregation of WP during sterilization or pasteurization impacts food quality important to shelf-stable beverages. Preheating WP improves the thermal stability at neutral acidity, and forming complexes with other molecules to provide charge and/or steric hindrance can be used to improve thermal stability of WP at acidic conditions. Conversely, aggregation properties of preheated WP upon acidification can be used to create unique functional properties. Therefore, studying properties of preheated WP can broaden its application in the food industry.
Gelation of preheated WP and pectin …
