Question

What’s happen when Chlorogenic acid react with citric acid?

Answer 1

Answer:

Chlorogenic acid was isolated from green coffee beans.210 It has also been found in the seeds and leaves of many dicotyledonous plants. It is thermally unstable and is readily decomposed to quinic acid and caffeic acid. Chlorogenic acid accounts for 5–10% of coffee beans, which is a much larger amount than caffeine (1–2%). Chlorogenic acid strongly influences the taste of coffee, such as astringent, sweet, and sour tastes, which change with the concentration. It is also considered to be the origin of the unpleasant complex taste found after prolonged brewing. It forms greenish-black compounds in the presence of Fe(III) ion. Due to its radical-capturing ability, an antioxidant activity is expected.211
