Starches Flashcards
starch is a type of
carbohydrate.
starch is produced by .
plants.
starch contrasts with
cellulose.
starch has subunit of .
glucose.
what is accelerated by freezing
retrogradation and syneresis.
what is the absorption of water and swelling, increasing viscosity, translucency and leaching of amylose?
gelatinization.
what is further leaching of amylose from the granule and implosion of granule?
pasting.
what is complete loss of granular structure after prolonged heating.
pasting .
the more pasting the lower.
viscosity.
if further heating of gelatinized starch is pasting, what is cooling after gelation?
retrogradation.
during gelation, energy is loss during cooling, which promotes H bonding between what molecules?
amylose.
As more amylose forms H bond, gelatinized starch solution is transformed into .
gel.
more amylose creates a more .
opaque gel.
less amylose creates a .
clearer gel.
what is the breaking and reformation of H bond in gel that leaves crystals, resulting in a more orderly arrangement of amylose molecules
.retrogradation
