5
test and name the instrument used to measure viscosity of the starch mixture
-Viscosity test, consistometer, how much the starch flows down a consistometer in 20 seconds
6
Explain how spread distance of the starch mixtures relates to viscosity
The further the solution travels, the lower viscosity, shorter higher
7
Which starch(es) most effectively formed a solid gel (achieved a gel at the lowest % starch)? How does the spread distance support your answer
Corn
8
Which starch(es) least effectively formed a solid gel (required a higher % starch to set, or didn’t set at all)? How does the spread distance support your answer
- Waxy Maize, it did not spread well, still liquid
