Abstract

PURPOSE: To remove impurities from vegetable components with an adsorbent formed by adding a metal salt to an extract solution, and the electrical conductivity of a salt formed as a by-product at the same time.
CONSTITUTION: A metal salt, e.g. aluminum sulfate or sodium aluminate, is added to an extract solution of sweetening components of stevia, hydrangeas, licorices, or active constituents of other vegetables, and the mixture is meutralized with an acid or alkali to form a hydroxide, which removes most of the impurities, e.g. polyphenols, proteins, etc. The salt thus formed at the same time makes the solution electrically conductive. The rest of the impurities are removed by electrolysis of Al using the metal of the hydroxide as an electrode based on the electrical conductivity, thus giving the active constituent at a high separation efficiency.
