FULVIC ACID AQUEOUS SOLUTION DERIVED FROM HUMIC SUBSTANCES AND PRODUCTION METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a fulvic acid aqueous solution derived from humic substances that is easy to drink while providing a sufficient effect by being drunk, and to provide a production method thereof.;SOLUTION: A first aging step is performed by preparing, in a tank, a suspension of 100 kg of powder derived from humic substances which are obtained by dehydrating and drying humic soils obtained from underground, and 600 L (3-6 times of the weight of the powder) of pure water. A second aging step is performed by dispensing the supernatant of the suspension after the first aging step, or filtering it, to obtain a liquid for aging the obtained liquid until the concentration of the humic acid becomes 400 mg/L or less.;COPYRIGHT: (C)2014,JPO&INPIT
