Imagine the golden glow of premium turmeric locked in, preserved as if time itself paused. That’s the promise of cryogenic processing for Lakadong turmeric: freezing temperature, minimal heat, maximum effect. Turmeric’s big enemies are heat, light, moisture, and prolonged exposure to air. These degrade curcumin (the active compound), diminish essential oils, and wash away aroma and flavour. Modern research shows that techniques like freeze-drying (a kind of cryogenic drying) outperform sun-drying or hot-air drying in preserving curcuminoids, phenolic acids, flavonoids, and antioxidant activity. In a study titled Changes in curcuminoids and chemical components of turmeric, researchers found that freeze‐dried turmeric retained significantly higher content of these compounds compared to hot-air or sun-dried samples.
Working with Lakadong turmeric using such methods means you start with its inherently high curcumin & robust oils, and you avoid losing them in processing. Freeze drying involves freezing the turmeric rhizomes and then reducing the surrounding pressure to allow frozen water in the material to sublimate directly from ice to vapour. Because temperature stays low, heat-sensitive components remain stable. In the aforementioned study, freeze‐dried turmeric held far more antioxidants than samples dried by traditional methods.
Another research article, Optimizing drying techniques for turmeric evaluated methods like sun drying, convection oven drying, vacuum-oven, infrared, microwave, and freeze drying. It turns out freeze drying preserves both biochemical and structural integrity better than most other techniques.
Cryogenic grinding (i.e. using very low temperature to grind spices) is another route. One study, Effect of cryogenic and ambient grinding on flavouring components of … turmeric, compared flavour and colour retention of cryogenically ground turmeric vs ambient grinding. Cryo grinding preserved more flavouring, better colour value than ambient.
Lakadong turmeric already gives you deep gold, strong aroma, and high curcumin content. If you get a Lakadong product that's freeze dried or processed cryogenically, every pinch is more potent:
If the packaging says “freeze-dried” or “cryo grinding” and you see lab test results for curcumin & essential oils, that’s a good sign.
Freeze drying and cryogenic processing are more expensive than sun-drying or conventional drying. Not every producer may have access. Also, mis-handled freeze-dried turmeric (exposed to moisture, light) can degrade too. So, how the product is stored after processing matters a lot.
Also, even though freezing methods preserve most curcuminoids, some very small losses may occur when bringing things from frozen to room temperature, or during packaging etc. So the full chain—from harvest through freeze-drying, packaging, storage—needs care.
Cryogenic methods and freeze-drying aren’t just lab fancy words. They’re powerful tools to make sure Lakadong turmeric lives up to its premium promise: high curcumin, strong aroma, deep colour, preserved potency. If you’re investing in quality, go for Lakadong that’s processed with low heat or cryo techniques. Your golden milk, immunity shots, or spice blends will thank you.
