摘要: Chlorogenic acid can be separated and produced as free acid or as salts thereof from plant raw material extracts by means of gel permeation chromatography on cross-linked modified polysaccharides, especially on dextrans. To obtain the free acid, the aqueous extract must be adjusted to a pH in the range of about 2 to 2.8. By use of a column of sufficient length the isomeric 5-, 4- and 3-chlorogenic acid can also be separated by the process of the invention.

摘要: Roasted coffee with an increased chlorogenic acid content of more than 2.8% by weight or instant coffee powder with an increased chlorogenic acid content of more than 8.5% by weight have a better compatibility. The increased chlorogenic acid content is achieved either by adding chlorogenic acid or by extracting raw coffee and adding the optionally concentrated extract to the roasted coffee.
摘要翻译: 具有高于2.8重量%的绿原酸含量的增加的咖啡与具有大于8.5重量%的绿原酸含量的速溶咖啡粉具有更好的相容性。 增加的绿原酸含量可以通过加入绿原酸或者通过提取生咖啡,并将任选浓缩的提取物加入到焙炒咖啡中来实现。
