Lowacid

Lowacid is a descriptive term used in food, beverage, and nutrition contexts to indicate products that contain lower acidity than standard references. Acidity in foods is commonly expressed as pH and titratable acidity, and low-acid products are typically those with a higher pH or reduced titratable acidity compared with conventional versions. The designation is used to achieve milder flavor profiles, improved texture, and greater suitability for sensitive individuals, while aiming to preserve safety and stability.

Practices to achieve low acidity include selecting low-acid cultivars (for example, tomato or citrus varieties bred for lower acid content), blending with less acidic ingredients, and applying processing methods that remove or neutralize some acids. In wine, malolactic fermentation reduces malic acid, lowering perceived acidity; in juice production, ion-exchange, filtration, or calcium-based neutralization may reduce titratable acidity. In coffee, adjusting roast, grind, and extraction can lessen perceived acidity without changing pH dramatically.

Applications and considerations: low-acid products can be easier on the stomach for some consumers, and may be favored for culinary uses where sour notes are undesirable. However, acidity helps preserve foods and drives flavor and aroma; reducing it can affect safety, color, texture, and shelf life. There are no universal regulatory standards for the label, so "low acid" claims are often accompanied by analytical data such as pH or titratable acidity.
