Proteins are amino acids linked by ____ ____
peptide bonds
Denaturations happens before ____
coagulation
what is the relaxation of tertiary to secondary structure of a protein accompanied by decreasing solubility of a pro
denaturation
what is precipitation of pro as molecules aggregate? (egg whites)
coagulation
What state is the protein an uncooked food and most soluble
native state
what state is an unfolded structure and less soluble
denatured state
what state is a denatured protein bind together and form network, usually in gel or solid mass
coagulated state
What are the three phases of gelatin
phase 1 - hydration
phase 2 - dispersion
phase 3 - gelation
During what phase is there absorbing of 5-10x weight when heated in water where water is absorbed and gelatin swells and traps free water
phase 1 hydration
during what phase is stirring done to ensure homogenous dispersion
phase 2 dispersion
during what phase is refrigeration crucial where sol becomes gel
phase 3 gelation
What is the gelatin gold standard concentration
1 Tbsp/ 2 cups liquid
What is the gelatin gold standard temperature
fast cooling
