High-purity reference materials for accurate residue analysis

Overview

Malic acid is an organic compound with the molecular formula HO₂CCH(OH)CH₂CO₂H. It is a dicarboxylic acid that is made by all living organisms, contributes to the sour taste of fruits, and is used as a food additive. Malic acid has two stereoisomeric forms (L- and D-enantiomers), though only the L-isomer exists naturally. The salts and esters of malic acid are known as malates.

Uses

Malic acid is widely used in the food and beverage industry as a flavor enhancer and preservative. It is also used in the cosmetic and pharmaceutical industries due to its moisturizing and exfoliating properties. Additionally, malic acid is used in analytical chemistry as a reference material for various types of residue analysis.

Regulatory

Malic acid is approved for use as a food additive in the EU (E296), US, and Australia and New Zealand. It is often used in place of citric acid in sour sweets and other food products.

Monitoring

Monitoring the levels of malic acid in food and environmental samples is crucial for ensuring compliance with regulatory standards. High-purity reference materials are essential for accurate and reliable residue analysis.

Health Impact

Human Toxicity

Malic acid is generally recognized as safe when used in accordance with good manufacturing practices. However, excessive consumption can cause irritation of the mouth and digestive tract.

Environmental Impact

Effects on Wildlife

Malic acid is biodegradable and is not expected to have significant adverse effects on wildlife or the environment.

Safety Measure

Proper handling and storage of malic acid are essential to ensure safety. Personal protective equipment such as gloves and safety goggles should be used when handling the compound.

Regulation

Malic acid is regulated as a food additive and must meet specific purity criteria to be used in food products. It is also subject to regulations concerning its use in pharmaceuticals and cosmetics.

Analytical Standards

High-purity reference materials for malic acid are essential for laboratories conducting food and environmental analysis. These reference materials ensure accurate and reliable residue analysis, helping to maintain compliance with regulatory limits.
