Effect of Storage Conditions and Light Exposure on Curcumin Content in Turmeric Powder
Abstract
Turmeric powder is widely used in food and health applications and is often stored for extended periods. Curcumin, the main active compound in turmeric, is known to be unstable when exposed to light and environmental factors. This study aimed to determine the curcumin content in turmeric powder and evaluate the effect of storage conditions and light exposure on its stability. Analysis was conducted using UV-Vis spectrophotometry on samples stored under two conditions: exposed to light and protected from light. The initial curcumin content was 3.42%, which decreased by 1% in the light-exposed samples, while the content remained stable in samples protected from light. These findings indicate that storage conditions, particularly light exposure, significantly affect curcumin stability. Therefore, storing turmeric powder in dark conditions is recommended to maintain the quality and activity of its active compound.
