Lipids
Saturate and Unsaturated fats differ based on the...
Which three foods have we used for our labs during this unit?
Apples, Bananas and chips.
The name of the protein produced by enzymatic browning
Melanin
The process whereby lipids undergo chemical changes due to reactions with oxygen
Rancidity
The teacher's first name is
Joshua
Lipids are made of these three elements
Hydrogen, Carbon and Oxygen
Based on our labs, we know that these fruits contain PPO
Apples and bananas
Name of the enzyme responsible for causing enzymatic browning
Polyphenol Oxidase (PPO)
These things influence how quickly lipids undergo rancidity
Access to oxygen, temperature and light
What student group does the teacher run
FFA
Triglycerides, or fats, are made of two main parts
Carboxyl group (Glycerol) and Hydrocarbon chain
Why don't chips undergo enzymatic browning
These influence how quickly an item undergoes enzymatic browning (3 responses)
Access to oxygen, temperature and acidity
Rancidity occurs more quickly in this type of fat
Unsaturated
How old is that orange sitting on the front desk
4 days old (peeled on Monday)
A double bonded carbon is found in....
Unsaturated fats
Why wouldn't an apple undergo oxidative rancidity
Not enough lipids
In order to produce Melanin, PPO requires these two items
Oxygen and Phenols
This antioxidant can be added to foods to attempt to prevent oxidation
Vitamin C
We are studying oxidation because it relates to...
Food waste
Lipids are organic molecules because...
They come from living things
Why didn't the orange in class undergo enzymatic browning?
Due to the high acidity, presence of antioxidants (Vitamins C) and presence of citric acid.
What gas is pumped into food packaging to prevent enzymatic browning?
Nitrogen
These are the chemicals created by oxidative rancidity that result in "off" flavors
Aldehydes or Ketones
What was the name of the song that Mr. Capodarco showed?
