Problems solved by technology

[0004] Coffee beans are examples of raw materials containing a large amount of chlorogenic acid. However, coffee beans or coffee bean extracts contain caffeine. In addition, due to the astringency and grassy taste and odor from green coffee beans, or from The burnt and bitter taste of roasted coffee beans limits its application to various foods, cosmetics, etc.

Embodiment 1-

[0093] Embodiment 1-(1) and (2)

[0094] Mix 70 g of green coffee bean extract S70 g and 280 g of a mixed solvent of ethanol and water (ethanol / water mass ratio shown in Table 1), shake at 60° C. (or 50° C.) for 3 hours to contact, pass through a suction filter (nutsche ) filtration (using No. 2 filter paper) to remove the liquid portion, and the solid portion was washed with 280 g of 99.5% ethanol while directly sucking the filter. This solid part is dissolved in the mixed solvent (ethanol / water mass ratio=30 / 70) 300g of ethanol and water, after carrying out suction filter again (using No. 2 filter paper), wash filter cake with same solvent 300g, thereby recover Soluble components. The recovered fraction was concentrated with an evaporator until the dry solid content was 55% to obtain chlorogenic acid-containing substances I-(1) and (2) obtained by the method of the present invention.

Embodiment 2-

[0095] Embodiment 2-(1)~(8)

[0096] Mix 70 g of green coffee bean extract S, 280 g of a mixed solvent of ethanol and water (mass ratio of ethanol / water shown in Table 1), and 35 g of a dispersant (Silika 100F-A), and shake at 60° C. for 3 hours to make it After contacting, the liquid part was removed by suction filter filtration (using No. 2 filter paper), and the solid part was washed with 280 g of 99.5% ethanol while directly sucking the suction filter. This solid part is dissolved in the mixed solvent (the mass ratio of ethanol / water=30 / 70) 300g of ethanol and water, after filtering with suction filter again (using No. 2 filter paper), wash filter cake with same solvent 300g, thereby Recover the soluble components. The recovered fraction was concentrated with an evaporator to a dry solid content of 55% to obtain chlorogenic acid-containing substances II-(1) to (8) produced by the method of the present invention.

Embodiment 3-

[0097] Embodiment 3-(1)~(4)

[0098] The mixed solvent (mass ratio of ethanol / water shown in Table 1) of the green coffee bean extract S of the amount shown in Table 1, the ethanol of the amount shown in Table 1 and water, and the dispersant of the amount shown in Table 1 ( Silika100F-A) were mixed, shaken at 60°C for 3 hours to bring them into contact, filtered through a suction filter (using No. 99.5% ethanol was used to wash the solid portion of the filter cake. This solid part is dissolved in the mixed solvent (the mass ratio of ethanol / water=30 / 70) 300g of ethanol and water, after filtering with suction filter again (using No. 2 filter paper), wash filter cake with same solvent 300g, thereby Recover the soluble components. The recovered fraction was concentrated with an evaporator to a dry solid content of 55% to obtain chlorogenic acid-containing substances III-(1) to (4) by the method of the present invention.

Abstract

Disclosed is a method for production of a chlorogenic acid-containing material, which comprises the steps of: contacting a coffee bean extract (A) with a mixture of a water-miscible organic solvent (B) and water (C) under such conditions that the weight ratio between the components (B) and (C) [i.e., (B) / (C) ratio] given after the mixture is mixed with the component (A) becomes 70 / 30 to 99.5 / 0.5; and collecting a solid fraction. The method enables to produce a chlorogenic acid-containing material having reduced abnormal taste / odor in a simple manner.

Description

technical field [0001] The present invention relates to the production of a chlorogenic acid-containing substance with reduced odor and odor. Background technique [0002] Recently, attention to the physiological effects of various ingredients contained in food has increased, and the Ministry of Health, Labor and Welfare of Japan has also granted permission as food for specific health use to foods containing such ingredients involved in physiological functions and biological activities. These foods are commercialized in the form of beverages, yogurt, soup, miso juice, home-cooked dishes such as hamburgers, and lozenges and lozenges. It is recommended to take them 1 to 2 times a day. [0003] Various raw materials have been proposed as raw materials having physiologically active functions, and polyphenols are proposed as raw materials having physiologically active functions such as antioxidative action, blood pressure lowering action, and liver function improving action (Pate...
