Impurity Evaluation of Gelatin Using Atomic Absorption Spectrophotometer

User Benefits

- Impurities in gelatin can be easily evaluated using an atomic absorption spectrophotometer (AA). - Efficient measurement is possible by using the flame method (air-acetylene flame). - High sensitivity data can be obtained from gelatin measurement using the AA-7800.

Introduction

Gelatin is used for gelification of solutions and to add viscosity. Therefore, it is widely used as a gelling agent, thickening agent, and stabilizer in various fields such as food and medicine, and its usage rate is increasing, especially in Japan. The Japanese Pharmacopoeia specifies evaluation methods for strength, identification, purity, and conductivity of gelatin. This article describes purity tests on gelatin using the flame method of atomic absorption spectrophotometer, and the effectiveness of this method is discussed.
