What is the primary function of amylose in starch?

  • Forms a highly branched, bushy type of structure
  • Contributes to the cohesion and thickening properties of starch
  • Produces gel rigid to a certain degree and holds a shape when molded
  • Contributes to the gelling characteristics of cooked and cooled starch mixtures (correct)

In which type of starch is amylopectin found mostly?

  • Root starches (tapioca/cassava, potato, sweet potato, arrowroot) (correct)
  • Cereal starches (corn, wheat, rice, except waxy varieties)
