酒石酸

Origin

L(+)-Tartaric acid, also known as tartaric acid, is a naturally occurring organic acid found in many plants, particularly grapes. It is a byproduct of the wine industry, being deposited as potassium bitartrate (cream of tartar) during fermentation. Commercially, it is produced from these deposits. The L(+) form is the most common isomer.

Usage

Tartaric acid is widely used in the food and beverage industry as an acidulant, antioxidant synergist, and flavoring agent. It contributes a tart or sour taste to foods and beverages. It is commonly found in fruit juices, jams, jellies, candies, and baked goods. In winemaking, it is crucial for maintaining chemical stability and influencing the flavor profile. Tartaric acid also functions as a leavening agent when combined with baking soda. Furthermore, it is used in some pharmaceutical applications and as a component in certain industrial processes.

Side Effects

Tartaric acid is generally recognized as safe (GRAS) by regulatory bodies when used in accordance with good manufacturing practices. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has established an Acceptable Daily Intake (ADI) of 'not limited,' meaning that, at the levels used in food, it poses no significant health risk. However, excessive consumption of tartaric acid can lead to gastrointestinal discomfort, such as diarrhea. Individuals with kidney problems should exercise caution, as high doses could potentially exacerbate their condition. Allergic reactions are rare but possible. No significant long-term health effects have been associated with its consumption at typical dietary levels.

Regulatory Status

Tartaric acid (E334) is permitted for use as a food additive in many countries, including those in the European Union, the United States, and Canada. Regulations specify the conditions of use and maximum permitted levels in various food categories. In the EU, it is listed as an authorized food additive with specific uses defined in Annex II of Regulation (EC) No 1333/2008. In the United States, it is generally recognized as safe (GRAS) under FDA regulations.
