The Day I Realized Most Turmeric Is Not What We Think It Is
A lot of turmeric on store shelves is not telling you the full truth.
Some of it is weak. Some of it is padded with fillers. And some, which still bothers me, is artificially dyed to look potent when it is not.
When we started sourcing turmeric seriously for Living Roots, I learned something most people never hear. Curcumin content can vary wildly, from as low as 2 percent to over 7 percent, depending on where and how the turmeric is grown. Curcumin is the compound everyone actually wants. It is responsible for turmeric’s deep color and most of its benefits.
That discovery sent me down a rabbit hole. Along the way, I learned a few simple, old school tests that farmers and spice traders have used for generations. No lab coat required. No fancy equipment. Just your senses, a little chemistry, and curiosity.
Today, I want to show you how to test turmeric at home and why our Lakadong turmeric, with about 7 percent curcumin, behaves completely differently than the 2 to 3 percent turmeric most of us grew up with.
Why Color Actually Matters More Than You Think
Let’s talk about the elephant in the room. Color.
High curcumin turmeric is not just yellow. It has a deep, warm reddish orange undertone, almost brick-like when you pile it up. Lakadong turmeric from Meghalaya, India is famous for this. When you compare it side by side with standard grocery store turmeric, the difference is honestly shocking.
Pro Tip: Brighter yellow does not mean better turmeric
That's right, brighter yellow does not mean better turmeric. In fact, sometimes it means the opposite.
Some suppliers add artificial yellow dyes to make low curcumin turmeric look vibrant. These dyes do not behave like real curcumin. They do not stain the same. They do not react the same. Once you test for it, the illusion falls apart fast.
The Baking Soda Test That Never Lies
This is the test that made me say “oh wow” the first time I tried it.
Why this works
Curcumin is alkaline reactive. When it meets a base like baking soda, it changes color, shifting from yellow or orange to a deeper reddish brown. Artificial dyes usually do not react at all.
What you need
- ½ teaspoon turmeric
- A pinch of baking soda
- A few drops of water
- A white plate or bowl
Step by step
- Place the turmeric on the plate.
- Add a few drops of water to make a paste.
- Sprinkle a pinch of baking soda on top.
- Watch closely for 10 to 30 seconds.
What you will see
Pure, high curcumin turmeric: The color deepens dramatically into a reddish brown, almost rust-like shade.
Low quality or dyed turmeric: Little to no change, or a dull muddy color.
When we run this test with our Living Roots Lakadong turmeric, the reaction is immediate and intense. With typical store bought turmeric, it is often underwhelming. Sometimes nothing happens at all.
That contrast alone tells you a lot.
The Water Test That Reveals Fillers
This one surprised me because it is so simple and so revealing.
What you need
- A clear glass
- Lukewarm water
- One teaspoon turmeric
Step by step
- Fill the glass with water.
- Gently add the turmeric.
- Do not stir.
- Observe for 5 to 10 minutes.
Results
- Pure turmeric: Settles at the bottom while the water remains mostly clear or lightly tinted.
- Adulterated turmeric with flour or starch: The water turns cloudy or dark yellow as fillers dissolve.
Here is why this works. Real turmeric powder is relatively heavy. Fillers are lighter and disperse quickly. This test will not catch everything, but it catches more than you would expect.
The Palm Test That Old Spice Traders Swear By
I learned this one from a spice merchant who laughed and said, “Your skin knows.”
Step by step
- Rub a pinch of turmeric into your palm.
- Massage for about 20 seconds.
- Rinse with water.
Results
High curcumin turmeric: Leaves a deep yellow stain that lingers.
Low quality turmeric: Washes off easily or leaves a dull, powdery residue.
Lakadong turmeric stains like it means business. That is curcumin doing what it does best.
A Serious Note on Metanil Yellow
This part is not fun, but it matters.
Metanil Yellow is a synthetic dye sometimes illegally used to enhance turmeric color. It is toxic and absolutely not something you want in your food.
The test
Adding a strong acid such as hydrochloric acid to turmeric powder.
Results
Pure turmeric: No dramatic color change other than the normal yellow to orange shift.
Metanil Yellow present: Turns pink immediately.
Most people will not perform this test at home, and that is completely fine.
Pro Tip: The key takeaway is this. Unnatural brightness is a red flag, especially when other tests do not behave as expected.
Why Lakadong Turmeric Is in a Different League
Most commercial turmeric falls around 2 to 3 percent curcumin. That is the industry norm.
Lakadong turmeric averages 6 to 9 percent curcumin. Ours consistently tests around 7 percent.
That difference shows up everywhere.
- Deeper red orange color
- Stronger aroma
- More dramatic baking soda reaction
- Less powder needed when cooking
- Richer flavor with a subtle bitterness, which is a good sign
Did You Know? High curcumin turmeric was historically prized for trade, but modern mass production prioritized yield over potency. Lakadong resisted that shift because of its geography. Mineral rich soil, heavy rainfall, and traditional farming methods all play a role.
Nature did the heavy lifting here.
Look at the Photos and Trust Your Eyes
When we line up photos of standard store bought turmeric, artificially dyed turmeric, and our Lakadong turmeric, the difference is unmistakable.
One looks pale.
One looks neon.
One looks deep, earthy, and naturally red.
Your eyes are not lying to you.
What I Recommend You Do Next
If you already have turmeric at home, test it. Seriously. Make this a five minute experiment. You will learn more than any label could ever tell you.
If you want to experience what real, high curcumin turmeric tastes like and how it behaves, try our Living Roots Lakadong turmeric. Use less. Notice the color. Notice the staining. Notice the reactions.
That is not marketing. That is chemistry and tradition lining up.
Try it in golden milk, curries, or even warm water with black pepper. Compare it side by side with what you already have. Run the tests yourself.
Once you do, you will never look at turmeric the same way again.
| Test | Method | Pure Result | Adulterated Result |
|---|---|---|---|
| Water Test | Add a teaspoon to a glass of lukewarm water. Do not stir. | Settles at the bottom; water remains clear/pale yellow. | Settles, but the water becomes cloudy or dark yellow. |
| Palm Test | Rub a pinch on your palm with your thumb for 20 seconds. | Leaves a deep, bright yellow stain on the skin. | Washes off easily or leaves a dull/powdery residue. |
| Metanil Yellow | Add strong acid (like HCl) to the powder. | No change (except the normal yellow-to-orange). | Turns pink immediately (indicates toxic chemical dyes). |

Shop Our CollectionFrequently Asked Questions About Turmeric Authenticity
How can I tell if my turmeric is pure at home?
You can test turmeric at home using simple methods like the baking soda test, water test, and palm test. Pure turmeric with high curcumin content will react strongly with baking soda by turning reddish brown, settle cleanly in water without cloudiness, and leave a lasting yellow stain on your skin. Adulterated turmeric often shows weak reactions, cloudy water, or washes off easily.
What does the baking soda test reveal about turmeric quality?
The baking soda test helps identify curcumin content. Curcumin is alkaline reactive, so when mixed with baking soda, high quality turmeric turns a deep reddish brown. Low quality turmeric or turmeric dyed with artificial color usually shows little to no color change, making this one of the easiest ways to spot fake or diluted turmeric.
Why is Lakadong turmeric considered higher quality than regular turmeric?
Lakadong turmeric naturally contains much higher curcumin levels, typically between 6 and 9 percent, compared to the 2 to 3 percent found in most store bought turmeric. This higher curcumin content results in deeper color, stronger aroma, more intense flavor, and more noticeable reactions during authenticity tests like baking soda and palm staining.
Where can I buy authentic Lakadong turmeric with high curcumin content?
You can purchase authentic Lakadong turmeric with approximately 7 percent curcumin directly from Living Roots. Our turmeric is sourced specifically from the Lakadong region of Meghalaya, India, and selected for purity, potency, and natural color without dyes or fillers. If you want to experience the difference that real high curcumin turmeric makes, this is the best place to start.
Can turmeric be artificially colored to look more potent?
Yes. Turmeric can be adulterated with synthetic colorants to make low-quality powder appear brighter and more vibrant. A neon-yellow appearance does not necessarily indicate high curcumin content. Natural high-curcumin turmeric tends to have a deeper yellow-orange to reddish-orange color, along with a strong aroma and pronounced staining. Simple home tests can provide clues, but laboratory testing is the most reliable way to confirm turmeric purity and curcumin concentration.
How much curcumin should high-quality turmeric contain?
Curcumin content varies significantly among turmeric varieties and growing regions. Many conventional turmeric powders contain around 2 to 3 percent curcuminoids, while naturally high-curcumin varieties such as Lakadong can reach approximately 6 to 9 percent. However, color alone cannot determine the exact curcumin percentage. For a reliable measurement, look for turmeric that has been independently laboratory tested for curcumin content.
