Unfolding of a protein can be termed as
a. Reduction
b. Oxidation
c. Denaturation
d. Renaturation
The functionality of a substance is defined as any property, nutritional or not, that intervenes in its use. This depends on its physical and chemical properties that are affected during food processing, storage, preparation and consumption. For example:
A. Bakery: the viscosity and the ability to form dough is related to the proteins of wheat gluten.
B. Meat products: texture and succulence are dependent on water soluble meat proteins
C. Dairy: texture and curd properties of dairy products are due to the colloidal structure of casein micelles
D. Cakes (cakes) and desserts: depend on the foaming and gelling properties of the proteins in the egg white
E. All are correct
Which of the following might cause the denaturation of a protein? Select all that apply.
A. Highly acidic conditions
B. Highly basic conditions
C. High concentrations of salt
D. High heat
