PROBLEM TO BE SOLVED: To provide a production method of natural product extraction beverage for extracting coffee or the like by using electrolytic reduction water in which an oxidation reduction potential of an extract is minus.SOLUTION: Provided is the production method of natural product extraction beverage for extracting coffee or tea by using hot water of electrolytic reduction water including a dissolution hydrogen molecule concentration. Means using electrolytic reduction water obtained by performing electrolysis of heated raw material water, means for extracting extract under high pressure in a closed vessel, and means for adding at least one dissolution hydrogen molecule stabilizer selected from polysaccharide and polyphenol to the electrolytic reduction water are provided, and among the three means, at least one means is used for extracting coffee or tee by suppressing vaporization of the dissolution hydrogen molecule, and the oxidation reduction potential of the extract is made equal to or less than 0 mV. |
