Curcumin (diferuloylmethane) is the principal yellow pigment and bioactive constituent of turmeric, obtained from the rhizomes of Curcuma longa, a perennial plant belonging to the Zingiberaceae family. Turmeric has been cultivated and used for centuries in South and Southeast Asia as a spice, colouring agent, preservative and traditional medicinal ingredient. Curcumin constitutes about 3-4% of turmeric in the report and is characterized as an orange-yellow crystalline powder that is practically insoluble in water.
The traditional applications of turmeric include food preparation, topical formulations and Ayurvedic remedies. Curcuminoids present in turmeric have attracted extensive research because of their antioxidant and anti-inflammatory properties, along with reported antimicrobial, antimutagenic and other biological activities. Curcumin is also widely investigated for applications associated with dietary supplements, functional foods, personal care and pharmaceutical research.
Commercial curcumin production involves extraction and purification of turmeric, with ethanol-water and other solvent-based extraction methods described in the report. The project also covers turmeric oil extraction, product characterization, purity testing, plant requirements, market analysis, suppliers, plant layout and project economics. The proposed plant capacity is 255 Kg./Day, with the report providing detailed cost estimates and financial indicators for establishing the facility.

Curcumin is the principal yellow pigment and bioactive component extracted from turmeric rhizomes.
It is obtained from Curcuma longa, a perennial herb belonging to the Zingiberaceae family. Curcumin is also known as diferuloylmethane and turmeric yellow, and the report identifies it with INS No. 100(i). Commercial extraction generally involves processing dried turmeric to separate curcuminoids from the plant material, followed by purification and testing to obtain the required product quality.
Curcumin is used in food, dietary, personal care and research-oriented applications.
Turmeric and curcumin have a long history of use as food spices and colouring agents, while curcumin is also investigated for applications associated with functional foods, supplements, cosmetics and pharmaceutical research. The report discusses antioxidant, anti-inflammatory, antimicrobial and other biological activities. Commercial applications depend on product specifications, purity, regulatory requirements and the intended end use.
Curcumin can be extracted from dried turmeric using solvent-based extraction followed by separation and refinement.
The report describes grinding dried turmeric, separation, solvent extraction using ethanol and water, extraction using ethanol-water mixtures, and extraction using petroleum ether. It also covers filtration, conversion of oleoresin to curcumin, purity testing and other technical methods. The selection of an extraction process depends on the desired product characteristics, raw material quality, solvent system, process conditions and downstream purification requirements.
The principal raw material for curcumin extraction is turmeric derived from the rhizomes of Curcuma longa.
The report covers plant raw material requirements and processing of dried turmeric, including grinding and moisture analysis. Depending on the selected extraction technology, suitable solvents and processing materials are also required. Supporting requirements can include filtration, evaporation, storage, material handling and laboratory testing facilities. Raw material quality, curcuminoid content, moisture and cleanliness can influence extraction performance and final product quality.
A curcumin manufacturing plant requires equipment for size reduction, extraction, separation, concentration, storage and quality testing.
The report specifically discusses crushers, evaporators, filter presses, boilers, extractors, pumps, storage tanks, material handling equipment, laboratory testing equipment and digital weighing scales. Depending on the process configuration, additional equipment may be required for solvent handling, purification and turmeric oil processing. Equipment selection should consider plant capacity, material characteristics, solvent compatibility, process safety, automation requirements and product specifications.
Curcumin extraction performance is influenced by raw material quality, particle size, moisture, solvent composition, extraction time and process conditions.
The report includes moisture analysis of dried turmeric, grinding and separation, extraction using ethanol and water, optimization at different time intervals, and comparative solvent extraction methods. Effective filtration, concentration and refinement are also important for achieving the required product quality. Consistent process control and appropriate purity testing help maintain reproducible extraction performance and finished-product specifications.
