The extraction of Yellow spice has emerged as a lucrative business in the nutraceutical, food, pharmaceutical, cosmetic, and wellness industries. Yellow spice has multiple bioactive compounds in it but curcuminoids have been extensively researched for their health benefits and yellow color.
There are growing opportunities for entrepreneurs for the commercial extraction of curcumin from Yellow spice rhizomes. A well-designed Separation plant can utilize the agricultural produce and make it more valuable for the industries manufacturing nutraceuticals, dietary supplements, food ingredients, personal care products, and more.
What Is Curcumin?
It is a polyphenolic compound naturally occurring in Yellow spice (Curcuma longa). It is a member of curcuminoids, a class of six phenolic compounds, of which three are major—Curcuminoids, demethoxycurcumin, and bisdemethoxycurcumin.
It is a popular herbal extract that is used for its biofunctional properties and is available in various grades depending on the application.
The composition of the final curcuminoid extract depends on:
- Type of turmeric
- Cultivation practices
- Separation technology
- Formulation requirements
Moisture and other contents of Yellow spice rhizome also affect the quality and yield of curcumin.
Why Is the Curcuminoid Separation from Turmeric Important?
Yellow spice is cultivated and consumed globally as a spice. Its value could be enhanced as a botanical extract for nutraceutical, pharmaceutical, and cosmetic applications. The extraction industry caters to diverse business verticals:
- Nutraceutical and supplement industry
- Functional foods and beverages
- Pharmaceuticals and medicine
- Cosmetics and personal care
- Natural colors and more
An herbal Isolation plant offers a way to add value to the agricultural commodity of turmeric.
Raw Materials Required to Start a Separation Business
The raw material for the Isolation is Rhizome. Depending on the business model, the dried Yellow spice fingers or Yellow spice powder could be used as raw materials.
Key specifications of the raw material relevant to the extraction business are
- Moisture content
- Cleanliness
- Foreign matter
- Microbial load
- Pesticide residue
- Heavy metals
- Storage conditions
The variation in Yellow spice composition affects the yield of Curcuminoids and the quality of the extract. Therefore, it is essential that the entrepreneur have a reliable supplier for consistent production.
Curcumin Isolation Process
The manufacturing process involves several unit operations, and the technology selection depends on the scale of production, desired specification, and purity of the final extract. Here is a generalized flow diagram:
Selection and Cleaning
The good-quality Yellow spice is selected and sorted to remove extraneous matter like dirt, stone, plant matter, and other foreign bodies.
Cleaning ensures the protection of Separation equipment from abrasive materials and improvement in extract quality.
Drying and Reduction in Size
The cleaned Yellow spice is now dried to bring down the moisture content and is crushed or pulverized. This increases the surface area of the rhizomes, thereby improving the yield.
Extraction
The next step is the Separation of Curcuminoids from turmeric. Solvent Isolation is the commonly employed method for commercial production.
Separation technology selection and parameters like temperature, pressure, time of extraction, S:L ratio and others are chosen based on the desired specification and design of the plant. The choice of right technology and equipment helps extract the active principles from Yellow spice efficiently.
Filtration
The wet extract is filtered to separate the insoluble matter from the solution.
Concentration
The filtered extract is concentrated by evaporating a portion of the solvent. This reduces the volume and makes the extract easier to handle during further processing.
Purification
The purification process further purifies the extract to obtain the desired concentration and removes impurities.
Drying
The concentrated extract is now dried to form a powder. It is again milled and standardized to obtain uniform granules.
Quality Testing and Packaging
The powder is subjected to quality testing as per the specification and is packed in moisture-proof, light-proof packing.
Equipment Required
The machinery and equipment requirement depends on the capacity of the plant and technology employed.
Following is a list of a few pieces of equipment and machinery that could be needed for an Isolation business:
- Raw material cleaning system
- Pulverizer
- Agitators
- Filtering system
- Evaporator
- Dryer
- Purification system
- Storage tanks
- Packaging equipment
- Lab and quality control equipment
Applications of Curcuminoids
Curcuminoids extracted from turmeric find application in various industries:
In the Nutraceutical Industry
It is used in a wide range of formulations like capsules, tablets, powders, etc. It could be standardized and formulated with other excipients depending on the application.
In Functional Foods and Beverages
Curcuminoids find application in certain functional foods and beverages. Formulation depends on the product and applicable regulations.
In the Cosmetics Industry
Yellow spice extracts are used as an ingredient in various herbal cosmetic formulations.
In the Pharmaceuticals Industry
Curcuminoids are extensively studied for their pharmacological activities. Its application depends on the formulation, dosage, approval status, and other factors.
In the Natural Colours Industry
Yellow spice extract could also be used for its natural yellow color in some formulations, but that depends on the application and local regulations regarding colors in food.
Market Potential
The market potential for curcuminoid extraction from turmeric is linked to the overall demand for nutraceuticals, functional beverages, herbal medicines, and cosmetics. A new entrant should not assess only the selling price of the extract but also analyze various business aspects like
- Raw material procurement cost
- Extraction yield
- Solvent consumption
- Utilities
- Labor
- Quality testing
- Packaging
- Wastage
- Regulatory compliances
- Logistics and more
The product positioning is also an important aspect. A new plant could choose to target nutraceutical manufacturers of dietary supplements or target herbal product manufacturers, cosmetic industries, ingredient traders, or even export. The specification of the product would be different for each of these segments.
Profitability Factors of Curcuminoid Isolation Business for New Entrants
Several factors influence the profitability of a curcumin extraction business besides the selling price of the extract and raw material cost.
Some of these are:
- Availability of raw material at a competitive price
- Higher yield during Isolation
- Specification and purity of the final product
- Efficient solvent recovery
- Utilization of the plant capacity
- Product quality and customer base
Therefore, a detailed profitability analysis, including CAPEX and OPEX, production, sales, and working capital requirements, should be performed before starting a new business.
