L-(-)-Malic Acid Chemical Properties,Uses,Production

Description

ι-Malic acid is nearly odorless (sometimes a faint, acrid odor) with a tart, acidic taste. It is nonpungent. May be prepared by hydration of maleic acid; by fermentation from sugars.

Chemical Properties

L-Malic acid is nearly odorless (sometimes a faint, acrid odor). This compound has a tart, acidic, nonpungent taste.

Chemical Properties

clear colourless solution

Occurrence

Occurs in maple sap, apple, melon, papaya, beer, grape wine, cocoa, sake, kiwifruit and chicory root.

Uses

The naturally occuring isomer is the L-form which has been found in apples and many other fruits and plants. Selective α-amino protecting reagent for amino acid derivatives. Versatile synthon for the preparation of chiral compounds including κ-opioid rece

Uses

Intermediate in chemical synthesis. Chelating and buffering agent. Flavoring agent, flavor enhancer and acidulant in foods.

Definition

ChEBI: An optically active form of malic acid having (S)-configuration.

Preparation

By hydration of maleic acid; by fermentation from sugars.

Purification Methods

Crystallise S-malic acid (charcoal) from ethyl acetate/pet ether (b 55-56o), keeping the temperature below 65o. Or dissolve it by refluxing in fifteen parts of anhydrous diethyl ether, decant, concentrate to one-third volume and crystallise it at 0o, repeatedly to constant melting point. [Beilstein 3 IV 1123.]
