Document Type and Number:
WIPO Patent Application WO/2022/045305
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a technique for producing a coffee extract, the technique being capable of further reducing the turbidity of the coffee extract. Provided are: a method which is for producing a coffee extract with reduced turbidity and comprises a step for bringing a coffee extract into contact with glucoamylase of which the glucoamylase activity per 1 g of coffee bean is 32U or less; and a method which is for producing a coffee extract with reduced turbidity and comprises a step for bringing a coffee extract into contact with glucoamylase and galactomannanase, wherein the glucoamylase is used such that the glucoamylase activity is 0.24U or more per 1U of the galactomannanase activity.
