Description

  The present invention relates to a chlorogenic acid-containing composition.

Various materials have been proposed as materials having physiologically active functions. For example, polyphenols are those having physiologically active functions such as an antioxidant action, a blood pressure lowering action, and a liver function improving action. Chlorogenic acids, one of the polyphenols, have been reported to have a high blood pressure lowering effect, and are expected to be applied to supplements and foods and drinks.

A coffee bean is mentioned as a material containing many chlorogenic acids. Conventionally, techniques for improving the purity and stability of chlorogenic acid-containing compositions obtained by extraction from coffee beans have been studied. For example, after adjusting the extract of raw coffee beans or roasted coffee beans to a specific solid content concentration, contact with acid clay and / or activated clay, generation of precipitate immediately after production and storage for a long period of time It has been reported that the occurrence of secondary precipitation can be suppressed (Patent Document 1). In addition, after the chlorogenic acid-containing composition is dispersed or dissolved in a mixed solvent of an organic solvent and water and brought into contact with a specific adsorbent to remove precipitates, the chlorogenic acid concentration and pH are controlled within a specific range. In addition, there is a report that turbidity generated in an acidic region can be suppressed by further generating precipitates and solid-liquid separation when diluted to a concentration suitable as a beverage (Patent Document 2).
