CHAPTER 10: STARCH Flashcards
biggest starch
potato
smallest starch
rice
fractions of starch molecules
amylose and amylopectin
starch is made up of ______
glucose units
series of steps that is dependent on water and heat resulting in a viscous and thickened starch products
gelatinization
more soluble in h2o; ability to thicken, gel, and retrogradate
amylose
branched; larger molecule; thickens more but does not gel; less soluble in h2o
amylopectin
t/f: cereal gelatnizes at lower temp than root starch
false, root starch gelatinizes at lower temp than cereal
t/f: agitation or stirring causes stronger gel
false, it causes weaker gel
t/f: acids delay gelatinization and results in softer gel
true
t/f: fats lower gelatinization temperature
true
t/f: milk and eggs decreases firmness of the gel
false, it increases
setting of sol into a solidified mass
gelation
process which causes drying and hardening of cooked starches
retrogradation
starch with higher _____ content readily gels
amylose
