E100 is the food additive code for Curcumin, a natural yellow-orange colorant primarily obtained from turmeric (Curcuma longa) rhizomes.
E100 is widely used to provide yellow to orange shades in foods and beverages, and E100 is valued for natural-origin labeling and strong color strength at low use levels.
E100 performance depends on formulation pH, light exposure, processing temperature, and dispersion method, because E100 is poorly water soluble and can degrade under alkaline conditions and strong light.

DESCRIPTION
E100 is the European food additive designation for Curcumin, and E100 can be supplied as purified Curcumin or as turmeric-derived extracts standardized for curcuminoid content.
E100 is poorly soluble in water, so E100 is often formulated using emulsions, dispersions, solubilizers, or encapsulated forms to achieve uniform color distribution.
E100 color can shift and degrade in alkaline conditions, so E100 is typically formulated in acidic to near-neutral pH food systems for better stability.
E100 is sensitive to strong light and prolonged high heat, so packaging, antioxidants, and controlled processing can improve E100 color retention.
E100 may stain equipment and surfaces, so production hygiene and cleaning procedures should be designed for yellow pigment handling.
E100 quality for food use depends on specifications such as curcuminoid content, residual solvents, heavy metals, and microbiological limits.
E100 should be stored in tightly closed containers in a cool, dry place protected from light and moisture.
E100 powders can create airborne dust, so dust control and appropriate PPE are recommended during handling.
E100 should be used according to applicable food additive regulations, labeling requirements, and permitted use levels for the target market.

HANDLING AND STORAGE
Handling:
Use appropriate PPE including gloves and safety glasses, and use dust protection as needed.
Avoid generating dust and avoid inhalation of fine powder.
Prevent staining by using protective clothing and good housekeeping during handling.
Ventilation:
Use local exhaust or general ventilation where dust may be generated.
Maintain good airflow during weighing, charging, and blending operations.
Minimize airborne particulate accumulation in enclosed areas.
Storage:
Store in tightly closed containers in a cool, dry place protected from light.
Protect from moisture and contamination to maintain color strength and food-grade quality.
Keep containers properly labeled and sealed when not in use.
Spill and Leak Procedures:
Avoid dust generation and sweep or vacuum using suitable equipment.
Collect spilled material into suitable containers for disposal according to local regulations.
Clean residues promptly to prevent staining of floors, tools, and equipment.
Handling Precautions:
Select the appropriate E100 form such as dispersion or encapsulated grade based on the target food matrix and processing conditions.
Conduct stability testing for color retention under light, heat, and pH conditions relevant to the target application.
Rotate stock using FIFO practices to maintain consistent color performance and specification compliance.
