Which acids are allowed for acidification?

Which acids are allowed for acidification?

• A. Citric acid and lactic acid
• B. Tartaric acid and malic acid
• C. Acetic acid and formic acid
• D. Hydrochloric acid and sulfuric acid

Answer: (B)

The question tests which acids are appropriate and permitted for adjusting acidity in a wine-like beverage, focusing on acids that are natural to grapes and considered safe and suitable for food use. Tartaric acid is the primary acid found in grapes and is the standard choice for acidification because it provides stable acidity and preserves the wine’s balance without introducing off-flavors. Malic acid is the other major grape acid and is also commonly permitted as an additive in regulated contexts to fine-tune total acidity, especially when winemaking steps like malolactic fermentation influence the final pH and perception of sharpness. The other acids listed are not appropriate for acidification in this context. Acetic and formic acids are associated with vinegar and can impart undesirable, lingering aromas or flavors, making them unsuitable for wine adjustment. Strong mineral acids like hydrochloric and sulfuric acids are not used in beverages due to safety concerns and regulatory restrictions. Citric acid, while food-grade, is not the standard choice for wine acidification because it can alter flavor balance and stability in ways that grape acids do not. So, the acids that are correctly allowed for acidification are tartaric and malic acids.
