Abstract:
PURPOSE: A removing method of gastropoda through regulation of hydrogen ion concentration is provided to efficiently and safely peel off gastropoda adhered to the adhesive substrate by using acid and alkalinity in a short time. CONSTITUTION: A removing method of gastropoda comprises a step of peeling the gastropoda from the adhesive substrate by adding acidity agent or alkalinity agent. The acid agent comprises an organic acid or fruit juice. The organic acid is at least one selected from malic acid, citric acid, succinic acid, lactic acid, and fumaric acid. The fruit juice is at least one selected from lemon juice, grapefruit juice, Japanese apricot juice, and citron juice. The acidity agent includes hydrochloric acid. The alkalinity agent includes at least any one selected from NaOH, and potassium hydroxide.
