Differentiate between smoke point, flash point and fire point
Smoke point – Temperature at which fat/oil produces smoke,
Flash point (~ 600 ºF) - T at which tiny wisps of fire streak
Fire point (~ 700 ºF) – T at which oil burst into flames
Flash point (~ 600 ºF) - T at which tiny wisps of fire streak
Fire point (~ 700 ºF) – T at which oil burst into flames
19

20
Define plasticity of fats
Fats ability to hold its shape, but still be molded under light pressure
21
Describe the chemical change happening during rancidity
When triglycerides and/or fatty acids are broken down into smaller molecules that produce off-flavor and rancid odor
22
List the two types of rancidity
Oxidative Rancidity - Oxygen
Hydrolytic Rancidity - water
Hydrolytic Rancidity - water
23
Why is measuring by weight more reliable than by volume?
Volume is affected by density of the product, affecting the weight
24
Which method scoop or spoon and level gave the closest weight to the reference weight
Spoon and level
25
Which method, top read or side read gave the closest weight to the reference weight
side read
26
Why were samples labeled with a 3-digit code instead of a single digit?
So that the panelist cannot see which sample is which.
