Study Notes
Food Chemistry
- Food chemicals enhance flavor, color, texture, and preservation.
- Chemical additives prevent spoilage and extend shelf life.
- Modern food production leverages chemistry for efficient food processing, packaging, and distribution.
- Food chemistry enables the creation of healthier, more nutritious food options through fortification and supplementation.
- Food chemistry helps in the development of food safety measures.
Chemical Examples
-
Preservatives: Prevent spoilage and microbial growth:
- Sodium benzoate: Used for acid foods like sodas and pickles.
- Calcium propionate: Found in breads and baked goods.
- Nitrites: Used to cure meats and enhance their color.
-
Flavoring Agents: Enhance taste, aroma, and mouthfeel:
- Salt: Basic seasoning and taste enhancer.
- Sugar: Sweetener and flavor enhancer.
- Natural and artificial flavorings: Extract or copy complex flavors, such as vanillin.
-
Coloring Agents: Enhance visual appeal:
- Caramel coloring: Used in soft drinks, candy, and sauces.
- Annato: Derived from achiote seeds, used in cheeses, margarine, and dairy products.
- Beta-carotene: Adds yellow or orange color to foods, found naturally in carrots.
Chemistry in Cleaning Agents
- Cleansing agents, like detergents and soaps, rely on chemical reactions to remove dirt, grease, and grime.
- Surfactants lower surface tension, allowing water to more effectively wet surfaces.
- Chemicals in cleansing agents break down grease and oil, and help to remove bacteria.
Chemicals in Medicines
- Pharmaceuticals rely on specifically designed chemicals to treat and manage diseases.
- Medicines can target specific biological processes, promoting healing, relieving pain, or preventing illness.
- Examples include:
- Aspirin: Pain reliever and anti-inflammatory.
- Penicillin: Antibiotic used to treat bacterial infections.
- Insulin: Used to manage diabetes.
