L-Malic acid powder is usually white crystals or crystalline powder with a distinctive sour smell and can be freely soluble in water and ethanol, with a solubility of 67g/100mL at 20°C.

The L-Malic Acid produced by Healthful Biotech is synthesized through a one-step fermentation process using glucose as the raw material. Compared to traditional chemical synthesis and enzymatic methods for producing L-malic acid, it causes less environmental pollution, has higher purity, and is more eco-friendly and safer.

Malic Acid taste is close to the sour taste of natural apples. Compared with citric acid, the acidity, soft taste, long retention time, and no damage to the teeth and oral cavity. L-malic acid is conducive to the absorption of amino acids and does not accumulate fat in terms of physiological metabolism. It belongs to the new generation of food acid-flavored agents and is hailed as "the most ideal food acid-flavored agent" by the biological and nutritional circles. It is one of the most organic acids in the world's food industry and has good development prospects.

Quality and characteristics of L-malic acid

Optical Purity Analysis of L-Malic Acid


Chromatogram of D-Malic Acid Standard	Chromatogram of L-Malic Acid Standard	Chromatogram of Healthful Biotech's L-Malic Acid

The peak time of Healthful Biotech's L-Malic Acid product is consistent with that of the L-Malic Acid standard. Furthermore, no peaks indicative of D-Malic Acid were observed in the sample. Therefore, it can be concluded that Healthful's L-Malic Acid is of high optical purity.

Calcium Analysis in L-Malic Acid

Comparison Chart of Calcium Precipitation in Solutions Containing 1g/L of L-Malic Acid, DL-Malic Acid, and Citric Acid (under ldentical Conditions)

product-501-502

Under identical conditions, within 24 hours, the amount of calcium ions precipitated by L-Malic Acid was lower than that by DL-Malic Acid and Citric Acid. Comparatively, foods utilizing L-Malic Acid can reduce the loss of calcium ions.

Application

Food Industry: The soft drinks prepared by L-Malic Acid are thirsty and refreshing, with Malic Acid flavor, close to natural fruit juice. Compared with citric acid, the heat produced is lower and the taste is better. Therefore, it is widely used in alcohol, beverages, jams, gum, and other foods, and has gradually replaced citric acid.

Cosmetics industry: L-Malic Acid contains natural moisturizing ingredients, which can easily dissolve the "adhesive" between the dead scale-like dead cells, which can remove the skin surface wrinkles. It can make the skin tender, smooth, and elastic, so it is well-favored in cosmetics formulas.

L-malic acid can be equipped with a variety of flavors and spices for multiple daily chemical products, such as toothpaste and shampoo. Compared with citric acid, the sour taste of L-Malic Acid is soft and chic, so foreign countries use it to replace citric acid as the new type of washing assistant and synthesize high-end special detergents.

Chemical Industry: It can be used as one of the synthetic raw materials for dirt removal and fluorescent whitening agents. Add to the worm adulhoretic or other varnish to prevent paint surfaces from cutting the skin. Polycolic resin and alcoholic acid resin produced with this kind of acid are plastic with special uses.

HSF Biotech's advanced Functional solid microcapsule Technology

1. Improve stability: Through embedding technology, malic acid is more effectively protected, allowing it to maintain stable properties under various environmental conditions and extending the shelf life of the product.

2. Improve the taste: Malic acid has a unique sour taste. Through encapsulation technology, the release speed and degree of malic acid can be controlled to make it more evenly distributed in the product, thereby improving the taste and flavor of the product.

3. Improve bioavailability: Embedding malic acid can better protect its molecular structure, making it easier to be absorbed and utilized in the human body.

4. Ease of processing and application: Embedded malic acid has better fluidity and dispersion, making it easier to add and mix during food processing and preparation.
