Study Notes
Oxygenated Compounds in the Food Industry
- Esters are used in the food industry to enhance or impart fruity flavors and attractive aromas.
- Aldehydes and ketones are used in the food industry to increase flavor of food.
- Carboxylic acids are used in the food industry to adjust pH and improve flavor.
Characteristics of Oxygenated Compounds
- Alcohols contain a hydroxyl group (-OH) attached to a saturated carbon.
- Example of an alcohol: Ethanol (ethyl alcohol), present in alcoholic beverages.
Buoyancy and Density
- The apparent weight of an object in water is less than its actual weight due to the buoyant force.
- Gravity is the force that attracts objects towards each other, typically towards the center of the Earth.
- Archimedes' principle states that the buoyant force acting on an object submerged in a fluid is equal to the weight of the fluid displaced by the object.
- Density is the measure of how much mass is contained in a given volume of a substance, influencing its behavior when submerged in a fluid.
This quiz covers the role of oxygenated compounds such as aldehydes, esters, and carboxylic acids in the food industry, including their functions and applications.
