What is one food antioxidants are found in?
100
molecule with same chemical formula but different structural formula
What is an isomer?
200
when oxygen reacts with the double bonds in a food
What is oxidative rancidity?
200
Anthocyanins
What type of pigment is in berries?
200
They slow down oxidation, hence preserving food
What are the purpose of Antioxidants?
200
one of two molecules that are mirror images of each other
What is an enantiomer?
300
increases shelf life, tastes better, fewer calories, ext.
What is two purposes of hydrogenation?

300
D
Are natural sugars usually D or L in shape?
400
Initiation, propagation, and termination
What are the three steps to oxidative rancidity?
400
The conjugation in long chains
What is the chromophore for caretenoids?
400
consumers assume they are less safe because they are not naturally occurring, can change color or after taste of food, less effective, ect.
