Turmeric Curing Recovery & Cured Yield from Fresh
Cures turmeric
Enter your fresh turmeric weight and recovery percentage to get the cured turmeric you'll end up with, the fresh-to-cured ratio, the water lost in curing and the value of the cured crop.

Next: expect ~220 kg cured (ratio ~4.6:1); boil until soft, dry to ~8–10% moisture, then polish — well-cured rhizome fetches a premium.
Recovery varies by variety, maturity and curing method; over-boiling dulls colour, under-drying invites mould.

From wet rhizome to bright, storable gold
Freshly dug turmeric is heavy, wet and perishable — and worth little until it's cured. Boiling the rhizomes spreads the curcumin so the colour is even and bright, drives off the raw smell and cuts the drying time; then days of sun-drying take the moisture down to about 8–10% so the crop is hard, snaps cleanly and stores for months. By the end you keep only about a fifth to a quarter of the fresh weight, but every kilo is worth far more.
This tool gives the cured turmeric yield, the fresh-to-cured ratio, the water lost and the value of the cured crop from your fresh weight and recovery. Use it to plan drying space and labour, to compare lots, and to price your output. Pair it with the Dehydration Ratio, Ginger Drying Recovery and Value Addition Profit tools for a full processing plan.

Frequently Asked Questions
What is turmeric curing?+
Curing is the post-harvest process that turns raw fresh rhizomes into the hard, deep-coloured cured turmeric of commerce. The fresh rhizomes are boiled until soft, then sun-dried for days until they rattle and snap. Curing fixes the colour, develops the aroma, kills the sprouting ability and makes the crop storable.
How is cured turmeric yield calculated?+
Cured turmeric = fresh weight × recovery%. Fresh turmeric cures down to roughly 20–25% of its fresh weight, so 1000 kg of fresh rhizomes typically gives about 200–250 kg cured. Enter your own recovery if you know it from past lots; the rest is moisture driven off by boiling and drying.
Why is the recovery only about a fifth?+
Fresh rhizomes are mostly water. Boiling and then days of sun-drying remove that water until the moisture is low enough for safe storage, which leaves only the dense, dry solids — about a fifth to a quarter of the starting weight. Higher fresh moisture or younger rhizomes give a lower recovery.
Why boil turmeric before drying?+
Boiling (or steaming) gelatinises the starch, spreads the curcumin pigment evenly so the colour is uniform, drives off the raw earthy smell, and shortens the drying time. Cured this way the turmeric is bright, hard and even-coloured. Drying without boiling gives a duller, blotchy, more brittle product.
What moisture should cured turmeric reach?+
Dry it down to about 8–10% moisture — at that point it is hard, snaps cleanly, and is safe from mould in storage. Drying too little leaves it leathery and prone to spoilage; the rhizomes should rattle and break rather than bend before you polish and bag them.
What is polishing and why do it?+
After drying, the dull, scaly outer skin is removed by polishing — rubbing the rhizomes in a drum or against a hard surface — to reveal a smooth, bright, attractive surface. Polished turmeric grades and sells better. A little turmeric powder is sometimes added during polishing to enhance colour.
Does over-boiling hurt quality?+
Yes — over-boiling dulls the colour, leaches curcumin into the water and can make the rhizomes soft and hard to dry evenly. Boil only until a needle passes through easily and the rhizomes give off their aroma, then stop and start drying. Under-boiling, on the other hand, leaves a raw smell and uneven colour.
Can I estimate value from this?+
Yes — enter your cured turmeric price per kg and the tool multiplies it by the cured yield to estimate the crop's value. Because curing concentrates the colour and storability, cured turmeric is worth far more per kg than fresh, which is why the recovery percentage matters so much to your return.
Are these figures exact?+
They are reliable planning figures. Real recovery shifts with variety, rhizome age and maturity, fresh moisture, how hard the crop is boiled and how thoroughly it is dried. Weigh a few lots through your own process to learn your true recovery, then use that percentage here for sharper estimates.
