Working Stages In Liquid Curcumin Manufacturing – Picture Courtesy: QUNOL

Liquid curcumin manufacturing doesn’t consist of a single step but multiple stages occur in this production to produce excellent-quality liquid curcumin. It includes several different testing studies, designing, extraction, and packaging.

And for your information, we’re describing all these primary working stages one by one in the following sectors.

Selection of Raw Material

Selection of Raw Material- Picture courtesy: MDPI

As you already know curcumin is derived from turmeric roots that are harvested largely from India and China. After that, these harvested plants are washed, cut, and dried either using direct sunlight or with dryer machines and then pulverized into finely ground powder that is used for the extraction of curcumin.

Extraction

In order to isolate curcumin from the turmeric roots, various methods are used in which manufacturers employ solvents, such as ethanol, carbon dioxide, and ultrasonic waves. These approaches mainly work by increasing the solubility of curcuminoids in solvents.

This step produces a concentrated form of curcumin, normally containing about 90-95% of curcuminoids.

Solvent Extraction

First and foremost is the solvent extraction method. It is one of the oldest methods of curcumin extraction and still is considered as standard for its isolation. Solvent extraction is widely used by commercial plants because of its lower cost.  After curcuminoids dissolution, these solvents are vaporized, generating less volatile curcuminoids in a more concentrated form.

Supercritical CO₂ (SC-CO₂) Extraction

You’ve guessed it right, in this procedure, carbon dioxide is used for extracting curcumin from turmeric. This method is named as such because of the supercritical state of carbon dioxide, which is achieved using high temperature and pressure critical points (31.1 °C and 7.38 MPa or 73.8 bar). In this state, it shows both liquid and gas properties. So, you’ll pass this SC-CO₂ through turmeric powder and this gas behaves as a solvent and dissolves curcuminoids. After that, SC-CO₂ and the extracted curcumin mixture are transferred to a separator device, where you lower the pressure. Consequently, SC-CO₂ transitions back to a gaseous state, which causes the precipitation of curcumin.

Ultrasound-Assisted Extraction (UAE)

It's like an assistant to the solvent extraction method. Ultrasonic waves are utilized to increase the solubility of curcuminoid compounds in solvent. The purpose of sound waves is to create cavitation bubbles in the solvents, which break the cell walls of turmeric and increase the discharge and solubility of curcumin in solvents. It is a more quick and cost-effective method owing to its less use of solvent.

Ultrasound-Assisted Extraction (UAE)

Microwave-Assisted Extraction (MAE)

You are spot on. This method is similar to the UAE method but instead of using sound waves, it utilizes microwaves. The energy of these waves is essential in heating the solvent and turmeric powder mixture, which aids in the dissolution of curcuminoids. It is a quick and sustainable method and is suitable for heat-sensitive compounds.

Microwave-Assisted Extraction (MAE)

Emulsification of Curcumin

Emulsification of Curcumin

As you are aware curcumin powders are very difficult for the body to absorb, therefore, liquid curcumin manufacturing uses different innovative techniques to boost the absorption rate of curcumin. By these procedures, you can transform powdered curcumin into a liquid state that is easily used by the body.

Now, the liquid curcumin is dissolved or suspended in various solvents, like water, oil, or glycerin to create a stable product. Sometimes, emulsifiers are also incorporated at this stage to improve the dispersion of liquid curcumin. Then, the resulting blend of liquid curcumin is uniformly mixed and homogenized. In this way, you can ensure that liquid curcumin doesn’t precipitate at the bottom after its packaging.

Quality Check and Packaging

Quality Check and Packaging

Once all the main formulation steps are completely done, now you can assess the quality of the product using various testing approaches. If the formulation successfully passes through quality control, then it’s time for packaging.

The liquid curcumin formulation is transferred to filling systems, where its specified volume is accurately dispensed into bottles or other packaging formats. After filling, the bottles are capped, sealed, labeled, and boxed. Finally, the formulation is ready for distribution.

6.What kind of equipment is present in liquid curcumin manufacturing?

7.What solubilization technologies are employed in liquid curcumin manufacturing?

Solubilization method- Picture courtesy: Crafter choice

Curcumin is naturally hydrophobic meaning it doesn’t dissolve in water under normal conditions. Hence, manufacturers employ different innovative solubilization techniques to improve their solubility and stability in water.

Micelle Technology	As you have already read about surfactants. They’re used in liquid curcumin manufacturing to improve its absorption. They form tiny structures made of two ends- the head that is hydrophilic (water-loving) and the hydrophobic tail (water-hating). When they are placed in water, they form tiny ball molecules with curcumin at their center. The tail ends go inward, interacting with curcumin, while the head ends are in contact with water.
Liposomal Encapsulation	In this technology, liposomes are used for encasing or encapsulating curcumin. Liposomes are hollow spheres formed by fat-like molecules called phospholipids. Yes, they are the same type of molecules, making up the outer boundaries or membrane of our cells. They are like microscopic delivery vehicles that deliver curcumin to target tissues.
Nano-emulsion Technology	It is a solubilization technique in which you’ll initially dissolve curcumin in a tiny quantity of oil. Then this oily phase is reduced into nano-sized minute droplets. Following that water and surfactants are added to stabilize the oily phase. By the end, you’ll notice the formation of the milky or clear solution. In this solution, curcumin is encased in nano-sized droplets that are homogeneously mixed with water.
Cyclodextrin Complexation	To put it in simple words, cyclodextrins are structures that have a ring or donut shape and are created from starch (sugar). Their core is water-hating, so it traps curcumin inside it, while its outer surface is water-loving, thus it attracts water. Curcumin is accommodated inside the cyclodextrin core, consequently, effectively increasing its solubility in water and stability in liquid formulation.

8.What packaging is included in liquid curcumin manufacturing?

Many people believe that packaging in liquid curcumin manufacturing is only used to make products look pretty. But what they don’t know it is also employed for product preservation, protection, and stability.

Here is a complete list of packaging formats that keep liquid curcumin safe and potent:

Glass and Plastic Bottles

Glass and Plastic Bottles

If you've visited supplement stores, you've likely seen ample supplies of liquid curcumin in glass or plastic. This sheer number of bottles is because numerous manufacturers prefer to pack their products in bottles. For forming plastic bottles, mostly FDA-approved plastic (HDPE or PET) is used. These bottles are less expensive and have shatter resistance.

On the other hand, glass bottles are used for premium and high-end packaging of liquid curcumin. You’ll see liquid curcumin in amber-colored glass bottles. This is because these bottles provide the highest form of protection against light and oxygen. Furthermore, glass doesn’t react with curcumin, thereby, preserving its potency.

Dropper Bottles

Dropper Bottles

As the name indicates, dropper bottles are sealed with dropper caps. They are the customers' dosing dreams. With droppers, customers not only have convenience in usage but also precision in dosing. You can find these bottles in both glass and PET plastic material.

9.What are the challenges associated with liquid curcumin manufacturing? How to solve them?

Liquid curcumin manufacturing is not as simple as one might think. As, it is comprised of different innovative approaches and specialized machines, which necessitate careful handling and management during operation.

However, issues still emerge during operation, despite your best efforts to prevent them. Are you interested in exploring ways to overcome these challenges? Then read the below-mentioned common challenges of liquid curcumin manufacturing and their remedies.

Issues in Curcumin Solubility

Curcumin Solubility

It is one of the biggest challenges in liquid curcumin manufacturing. Curcumin has a water-hating nature so, it has poor water solubility. This makes it difficult to form a stable and drinkable liquid formulation.

Solution

To solve this issue, you’re required to employ innovative procedures discussed in the above section. Some of these methods include micelle formation, nano-emulsions, and liposomal encapsulation. These methods improve curcumin dispersion in water by trapping it inside various molecules.

Poor Bioavailability of Curcumin

Poor Bioavailability

This challenge will arise even if you mix curcumin into the water and form a stable formulation. It is a well-known fact that curcumin has poor bioavailability and the body barely absorbs it. Because most of its fraction is degraded by the stomach before it exhibits its therapeutic effect.

Solution

Fortunately, there are some well-tested approaches to remedy this problem. You can use liposomal encapsulation in which liposomal bubbles move curcumin past the digestive tract. Moreover, you can add absorption enhancers, such as piperine to boost its uptake from the intestine.

Sensitivity of Curcumin to Environmental Conditions

Environmental Sensitivity

The potency of curcumin is hampered by its sensitivity to varying environmental agents. It is a significant challenge to maintain the stability of liquid curcumin over its shelf life as it degrades upon exposure to light and high temperatures. pH changes and oxidative environment also negatively impact its effectiveness.

Solution

However, there is no doubt that you can tackle this challenge with simple steps. For example, you can incorporate stabilizers and antioxidants to increase its stability. Moreover, sophisticated encapsulation approaches shield delicate curcumin from harsh elements. Besides this, you can use opaque or amber-colored packaging to safeguard liquid curcumin formulation from light.

Sedimentation of Curcumin

It is quite a concerning issue that you may encounter over time after preparing or packaging curcumin. You may observe that your product has curcumin particles settling down at the bottom.

Solution

To overcome this challenge, you can use various emulsifiers, for instance, lecithin or polysorbate 80. These agents will keep curcumin solubilized in water. Moreover, high-speed homogenization or ultrasonication techniques are recommended to form stable solutions. Lastly, the incorporation of gelling agents or viscosity modifiers is vital in improving the suspension of particles.

Earthy Taste of Curcumin

Taste  problem- Picture courtesy: 1-2 Taste EU

Let’s be real- curcumin has an earthy or slightly bitter taste when consumed raw. Hence, a bitter-tasting liquid formulation isn’t a hit among consumers.

Solution

This problem has an easy fix. For example, you could add flavor masking agents, such as natural fruity flavors, artificial flavoring agents, or sweeteners (stevia) during liquid curcumin manufacturing. Also, the encapsulation technique is favored by manufacturers because it stops curcumin from coming in direct contact with taste buds. Essential oils could be included in preparation to improve the flavor profile of these supplements.
