Study Notes
Acid Applications
- Lactic acid has limited applications due to its very low solubility.
- Lactic acid is used in the confectionery industry for the production of boiled sweets.
Acids in Food Production
- Citric acid is used in carbonated beverages and sugar confectionery as a preservative, giving a sour taste and preventing spoilage.
- Phosphoric acid primarily contributes to the food industry by adding a tangy and sour taste to soft drinks.
- Malic acid plays a crucial role in food production by enhancing flavor, texture, and stability in products like jams, jellies, and fruit preserves.
- Acetic acid primarily contributes to the stabilization of emulsions, ensuring that mixtures of oil and water remain stable and consistent.
- Tartaric acid is used in food production as an antioxidant, pH controller, and flavor enhancer, particularly in wine, candy, and jams.
- Fumaric acid is used in food production as a flavor enhancer, pH controller, and antimicrobial agent, commonly found in desserts, beverages, and candy.
Colors in Food Production
- Tartrazine is a synthetic color that is soluble in water and commonly used in food production.
- Beta-carotene is a natural color used in food production, whereas tartrazine is a synthetic color.
Acid Preferences
