How to maintain the biological activity of caffeic acid?
To maintain the biological activity of caffeic acid, we can follow these recommendations:
Storage conditions: Store caffeic acid in a cool, dry, and dark place.Exposure to light, heat, and moisture can degrade the compound and reduce its biological activity.Keep it away from direct sunlight and store it in a tightly sealed container to minimize exposure to air.
Temperature control: Caffeic acid should be stored at a stable and moderate temperature.Avoid high temperatures, as heat can accelerate the degradation of the compound.Room temperature or refrigeration (4-8°C) is generally suitable for storage.
Moisture control: Moisture can lead to the hydrolysis and degradation of caffeic acid.Keep the compound dry and protected from humidity by storing it in a well-sealed container with a desiccant or moisture-absorbing packet.
Avoid contact with reactive substances: Caffeic acid can react with certain metals, alkaline substances, and oxidizing agents, which can lead to the loss of its biological activity.Keep it away from such substances to prevent any chemical reactions.
Packaging: Use airtight and opaque containers to store caffeic acid.This helps to minimize exposure to air, light, and moisture, which can degrade the compound.Choose containers made of materials that are compatible with caffeic acid, such as amber glass bottles or sealed foil pouches.
Short-term storage: If we need to store caffeic acid for an extended period, consider dividing it into smaller portions and storing them separately.This reduces the frequency of opening the main container, minimizing exposure to air and moisture.
Check the specific storage recommendations provided by the supplier or manufacturer of the caffeic acid product us are using, as the optimal storage conditions may vary slightly depending on the specific formulation and purity of the compound.
