Oxidation of Food Flashcards
How can alcohols be classified?
Primary secondary tertiary
Depending on which carbon the hydroxyl group is attached to
What are diols?
Alcohols with two hydroxyl groups
What are triols?
Alcohols with three hydroxyl groups
What affects the properties of alcohols?
The ability to form hydrogen bonds
What can primary alcohols be oxidised to?
Aldehydes
What can secondary alcohols be oxidised to?
Ketones
Can tertiary alcohols be oxidised?
No
Aldehydes can be further oxidised to form?
Carboxylic acids
Oxidation can be identified by?
A decrease in the oxygen to hydrogen ratio, going from reactants to products
Carboxylic acids react with bases in neutralisation reactions to form?
Salts
Carboxylic acids can be reduced to aldehydes which can then be reduced to?
Primary alcohols
Reduction can be identified as?
A decrease in the oxygen to hydrogen ratio going from reactants to products
What is oxidation the major cause of?
Food spoilage
Oxygen can react with fatty acids in fats and oils, causing them to become?
Rancid
Antioxidants are molecules that prevent?
Other substances from oxidising
