Food Grade DL-Malic Acid Acidity Regulator Use For Candy

Malic acid, also known as 2-hydroxybutyric acid, has two stereoisomers due to the presence of an asymmetric carbon atom in its molecule. In nature, it exists in three forms: D-malic acid, L-malic acid, and their mixture DL-malic acid. It is a white crystalline substance or crystalline powder, with strong hygroscopicity, and is soluble in water and ethanol. It has a special pleasant sour taste. Malic acid is mainly used in the food and pharmaceutical industries.

Malic acid has three isomers: L-malic acid, D-malic acid and DL-malic acid. The naturally occurring malic acid is always in the L form and is found in almost all fruits, with the highest content in stone fruits. Malic acid is a colorless needle-like crystal or white crystalline powder, odorless, with a stimulating and refreshing sour taste.

The most common form is the levorotatory form, L-oxalic acid, which is present in the juice of immature plums, apples and grapes. It can also be obtained through biological fermentation from fumaric acid. It is an important intermediate product in the internal circulation of the human body and is easily absorbed by the body. Therefore, it is widely used as an excellent food additive and functional food in the fields of food, cosmetics, medicine and health supplements. The racemic form can be obtained by reacting fumaric acid or maleic acid with a catalyst under high temperature, high pressure conditions and the action of steam.

✅ ‌Natural Safety‌: L-lactic acid is an intermediate in the human tricarboxylic acid cycle. After metabolism, it generates CO₂ and water. It has passed the SGS allergen test, and heavy metal residues are ≤ 10 ppm 57.
✅ ‌Enhanced Efficiency with Reduced Dosage‌: A 0.05% - 0.2% addition amount can achieve the same acidity as citric acid, reducing production costs by 20% 26.
✅ ‌Process Adaptability‌: Resistant to high temperatures (≤ 150℃) and strong salt tolerance, suitable for high-temperature baking processing and high-salt sauce systems 67.
✅ ‌Cross-Application‌: Full specifications for food grade / cosmetic grade / industrial grade coverage, and support for custom compounding solutions

Food and beverages
Beverages: When combined with citric acid (with a recommended ratio of 1:3), it enhances the fruity aroma and delays the bulging of carbonated beverages by 26 hours.
Candies: Adding 0.1% - 0.3% to hard candies can achieve a lasting balance of sweetness and sourness, preventing browning at high temperatures.
Baking: Adding 0.05% to the dough can promote fermentation and increase the fluffiness of bread.
Health and beauty
Slimming products: Consuming 600mg daily can accelerate fat metabolism and lower cholesterol by 14%.
Cosmetics: Removing dead skin cell attachments, it is used in masks and lotions to enhance skin elasticity.
Industrial fields
Tobacco combustion enhancer: Adding 0.5% - 1.5% can reduce tar emissions and improve the burning flavor.
Environmental cleaning agent: Replacing traditional acidic rust removers, it reduces the risk of metal corrosion.
