Introduction:

There are three isomers of malic acid: L- malic acid, D- malic acid and DL-malic acid. The naturally occurring malic acid is L-shaped and is found in almost all fruits, with the most occurring in the kernel. Malic acid for colorless needle crystal, or white crystal powder, odorless, with a stimulating refreshing sour taste.

White crystalline or crystalline powder. Malic acid contains a chiral carbon atom and has two enantiomers, levomalic acid and dextromalic acid. L-malic acid, which occurs naturally, is found in unripe fruits such as apples, grapes, cherries, pineapples, and tomatoes. Dexmalic acid can be separated from racemates and used only as an experimental chemical. DL-malic acid is a colorless crystal. Relative density 1.601, Chemicalbook melting point 131 ~ 133℃, heat to 150℃ decomposition. Soluble in water, alcohol, slightly soluble in ether, insoluble in benzene. Easy deliquescence. This product is a strong acid with a pH value of 2.28 in 0.1mol aqueous solution at 170℃. It can damage mucous membranes and tooth enamel. DL-malic acid and L-malic acid are safe and non-toxic. Used as an acid in cool drinks. It can also be used in medicine, cosmetics, cleaning agent, whitening agent, etc.

Application:

L - malic acid as the important component of natural fruit juices, acidity compared with citric acid (sour taste better than citric acid 20%), but the taste is soft (higher buffer index), special fragrance, don't damage the mouth and teeth, metabolic amino acid absorption and no accumulation of fat, citric acid, is the new generation of food by biologists and nutrition known as "the most ideal food acidity agent." , has been replacing citric acid in foods for the elderly and children since 2013.
L-malic acid is an essential organic acid for human body and an ideal food additive with low calorie. When 50% L-malic acid is combined with 20% citric acid, it produces a strong natural fruit flavor.
Beverages (various refreshing drinks): soft drinks prepared by L-malic acid quench thirst and refreshing, with apple sour taste, close to natural juice. Some large domestic food companies, such as Wahaha Group and Jianlibao Group, began to use L-malic acid in their drinks.
L-malic acid is a cyclic intermediate of biological tricarboxylic acid, which tastes close to natural juice and has a natural fragrance. Compared with citric acid, L-malic acid produces less heat and tastes better, so it is widely used in wine, beverage, jam, chewing gum and other foods, and has a tendency to gradually replace citric acid. It is one of the organic acids with the largest consumption and better development prospect in the world food industry.

1, used as a sour agent for refreshing drinks and food, color retention agent for fruit drinks, preservatives (emulsion stabilizer for mayonnaise, etc.). 2, used in medicine, cosmetics, dental solution, metal cleaning agent, buffer, textile industry used in the blocking agent, industrial deodorant, polyester fiber used in the Chemicalbook fluorescent whitening agent raw materials and the manufacture of alkyd resin monomer, etc. 3. When used as a flavor enhancer, flavor enhancer, adjuvant and pH control agent, the United States prescribs no more than 6.9% in hard candy and approximately 6.7% in other foods, but neither malic acid should be used in baby food

In fine chemical industry:
L-malic acid is a natural skin moisturizer that can easily dissolve the "glue" between dry, scaly dead cells, thus removing skin wrinkles and making skin tender, white, smooth and elastic. Therefore, it is favored in cosmetic formulas. L-malic acid can be prepared with a variety of flavors, spices, used in a variety of daily chemical products, such as toothpaste, shampoo, etc. Compared with citric acid, L-malic acid has a soft and unique sour taste. Therefore, it is used to replace citric acid as a new detergent agent in foreign countries.

Zinc L-malate is used in toothpaste as anti-bacterial spot agent and anti-tooth stone agent, synthetic flavor formula, etc.
The role of skin care
Malic acid: gently remove the old waste excess cutin, strengthen skin metabolism.
Apple extract: can effectively reduce wrinkles and tighten skin, wake up tired skin and make dull skin even and bright.
Hamamelis extract: control oil, calm, comfort, help skin regeneration.
Hop extract: deeply moisturizes and prevents skin from aging.
Apple firm pores shrink water has the effect of regulating the secretion of skin oil and strengthening the delicacy of pores. It is very suitable for coarse and large skin with pores. For more serious oil parts, you can also use cosmetic cotton to compress the skin locally to achieve the maintenance effect of tightening pores

Used as a sour agent for cooling drinks (such as lactic acid bacteria drinks, milk drinks, soda, cola), frozen foods (such as sherffles, ice cream, etc.), processed foods (such as fruit wine, mayonnaise), color preservative Chemicalbook of fruit drinks, preservative and emulsifying stabilizer of egg yolk, etc. It is also used as medicine, cosmetics, dental cleansers, metal cleaners, buffers, coagulant inhibitors in the textile industry, and fluorescent whitening agents for polyester fibers.
