Scope

Scope: This document specifies the high-performance liquid chromatography method for determining the tannic acid content in wine grapes and wine. This document is applicable to the determination of tannic acid content in wine grapes and wine by high-performance liquid chromatography. Main technical content: The samples are extracted with a methanol solution, centrifuged at high speed, and then determined by high-performance liquid chromatography. The retention time is used for qualitative analysis, and the area external standard method is used for quantitative analysis. The quantitative limit of this method is 0.5 mg/kg.
