The ingredients found in Aldi's PurAqua sparkling water depend heavily on the specific product line and flavor. A common misconception is that all sparkling waters are the same, but Aldi's offerings range from simple, unflavored seltzers to complex, artificially-sweetened flavored drinks. For consumers watching their intake of sweeteners, preservatives, or other additives, understanding these differences is key.
Ingredients Vary by PurAqua Product Line
Unflavored PurAqua Sparkling Water
Unflavored PurAqua sparkling water is the simplest option, typically containing only carbonated water and carbon dioxide. This provides a basic, zero-calorie, sugar-free, and additive-free drink.
PurAqua Belle Vie Flavored Sparkling Water
PurAqua Belle Vie offers flavored sparkling water, often featuring natural flavors. These typically contain carbonated water and natural flavors, providing a subtle fruit taste without added sugars or complex additives.
PurAqua Flavored Sparkling Water Beverages (Bottles)
Some bottled flavored PurAqua sparkling water, such as Strawberry and Black Cherry, include artificial sweeteners and preservatives. Ingredients commonly found in these include carbonated water, citric acid, natural flavor, potassium citrate, aspartame, potassium benzoate (preservative), acesulfame potassium, and malic acid.
PurAqua Sparkling Frost Flavored Water
The Sparkling Frost line generally has the most extensive ingredient list. These are often fortified with vitamins and contain more complex additives. Ingredients can include carbonated water, malic acid, juice concentrate, preservatives (potassium benzoate and potassium sorbate), natural flavor, gums (acacia and ester), sucralose, green tea, color additives (beta carotene), and vitamins.
Breakdown of Common Ingredients
Carbonated Water
This is the foundation of all PurAqua sparkling products, created by infusing water with carbon dioxide ($CO_2$) under pressure, resulting in carbonic acid and the signature fizz.
Flavoring Agents
- Natural Flavor: Derived from natural sources to add taste.
- Juice Concentrates: Used in some flavors for taste and color.
Acidulants
- Citric Acid: A natural acid for flavor enhancement and tartness.
- Malic Acid: An organic acid that contributes a sour taste.
Artificial Sweeteners
Zero-calorie artificial sweeteners are used in many flavored PurAqua varieties:
- Aspartame: A non-saccharide sweetener containing phenylalanine.
- Acesulfame Potassium (Ace-K): A calorie-free substitute often combined with other sweeteners.
- Sucralose: An artificial sweetener derived from chlorinated sucrose.
Preservatives and Stabilizers
- Potassium Benzoate and Potassium Sorbate: Preservatives used to inhibit microbial growth and extend shelf life.
- Calcium Disodium EDTA: Protects flavor and prevents discoloration.
- Gum Acacia and Ester Gum: Stabilizers that help distribute flavor oils.
