Citric acid tamarind

Fruit acids (such as malic acid in plums, tartaric acid in tamarind, or malic, tartaric, citric acid, in figs) have analogously a laxative effect. [Pg.58]

Carboxylic acids are Bronsted-Lowry acids, they are proton donors. They are the most common type of organic acid. Among the simplest examples are formic acid H-COOH, that occurs in ants, and acetic acid CH3-COOH, that gives vinegar its sour taste. Acids with two or more carboxyl groups are called dicarboxylic, tricarboxylic, etc. The simplest dicarboxylic example is oxalic acid (COOH)2, which is just two connected carboxyls. Mellitic acid is an example of a hexacarboxylic acid. Other important natural examples are citric acid (in lemons) and tartaric acid (in tamarinds). [Pg.6]

Contains plant acids (16-18%) composed mainly of r/-tartaric acid (up to ca. 18%), with minor amounts of /-mahc acid. Citric acid has also been reported as a major component in the old literature, though it has not been detected in Indian tamarind (youngken). Other constituents include polyphenolics (catechin, epicatechin, and procyanidin), flavonoids (taxifolin, apigenin, eriodictyol, luteolin, and naringenin), sugars (20-40%), pectin, protein (2.8%), fat, vitamins (e.g., Bi and C), minerals (Ca, K, P, etc.), and tartrate (merck ... [Pg.584]
