For an institutional kitchen, the right Swarna parboiled rice is the one that cooks the same way in your own vessels, batch after batch. Trial it at your normal batch size rather than in a small pan, measure how much cooked rice each kilogram gives, and write the result into a specification with a broken limit and an approved reference sample. Then plan deliveries around the storage space you can keep dry.
Key takeaways
- Swarna (MTU 7029) is a long-established variety. The specification, not the name alone, fixes what you receive.
- Parboiled rice cooks firmer and less sticky than raw rice, which suits large batches and holding.
- Trial at batch scale and record water, time, cooked yield and how the rice holds.
- Cost per portion depends on cooked yield, so measure it rather than assume it.

Why kitchens choose parboiled Swarna
Swarna was released in 1982 as MTU 7029 by the rice research station at Maruteru in Andhra Pradesh, and it has since become one of the most widely grown rice varieties in India. Most canteens, hostels and caterers meet it as parboiled rice. Parboiled rice takes longer to cook than raw rice, but the cooked grains are firmer, less sticky and less likely to break up, which suits large batches and rice that is held hot before serving. Our comparison of parboiled and raw rice explains why.
SONIK’s Swarna parboiled rice is milled at Ghentugachhi to a firm, free-flowing grain for bulk cooking. Even so, your own trial in your own kitchen is the test that matters.

Run a batch-scale trial
A small pan on a single burner tells you little about a large vessel or a steam cooker. Wherever possible, trial at least one normal batch, and run it the way your kitchen actually works:
- Weigh the raw rice exactly, and wash it as you normally do.
- Use your usual vessel, water ratio and heat source, and note the cooking time.
- Weigh the cooked rice when it is done.
- Hold it the way you serve it, hot or covered, for your usual holding time, then check texture, breakage and stickiness again.
- Cook your current rice, or a second sample, on the same day under the same conditions.
- Ask the cooks who will use it. They notice changes in water absorption and timing first.
Measure cooked yield and cost per portion
Cooked yield is the cooked weight divided by the raw weight. It is the number that links the price of rice to the cost of a plate.
Hypothetical example: 10 kg of raw rice gives 26.5 kg of cooked rice, a yield of 2.65. At a serving of 150 g of cooked rice, each kilogram of raw rice gives 2,650 ÷ 150 = 17.7 portions. If the rice costs a hypothetical ₹38 a kg delivered, the rice in each portion costs about ₹38 ÷ 17.7 = ₹2.15.
A rice that costs a little more per kilogram but gives a higher and steadier yield can cost less per plate. Record the yield in every trial and on every new lot, and you will see changes before the cooks complain about them.
Write a specification you can repeat
| Line | How to state it (format examples only) |
|---|---|
| Product and process | Swarna, parboiled |
| Finish | Silky or non-silky; colour sorted or not |
| Brokens | Maximum % by weight, for example “brokens max 5%” |
| Moisture | Maximum %, for example “max 14% at dispatch” |
| Colour and appearance | Within the range of the approved reference sample |
| Foreign matter and defects | Any limits your institution or auditors require |
| Packing | 26 kg or 50 kg bags, and the marking |
| Documents | Invoice, and any test reports your auditors ask for |
If you buy for an audited canteen or a contract-catering account, also agree how each lot is identified on invoices and bags, so a complaint can be traced to a delivery. Our guide to keeping quality consistent across repeat orders covers reference samples, tolerances and change notices.
Bags, storage and delivery rhythm
SONIK packs rice in 26 kg and 50 kg bags. In a kitchen store the choice is practical. A 26 kg bag is easier for one person to carry and stack by hand; 50 kg bags mean roughly half as many bags to count, open and dispose of for the same tonnage.
Set the delivery frequency from your storage space and consumption, not the other way round. Rice keeps best in a dry, ventilated store, on pallets off the floor, issued first in, first out. Our guide to storing bagged rice through the monsoon covers the details.
Frequently asked questions
Should we buy parboiled or raw Swarna?
For large batches and food held before serving, parboiled is the usual choice, for the reasons above. Raw rice cooks softer and stickier. SONIK mills both, so you can trial Swarna raw rice alongside the parboiled rice if your menu needs it.
How often should we re-check the rice?
Check each new lot against the reference sample on arrival, and repeat the cooking trial whenever the yield, cooking time or water absorption changes noticeably, or when the supplier tells you the crop has changed.
To arrange a quotation for a kitchen, hostel or catering contract, send the product, monthly quantity in MT, 26 kg or 50 kg bags, delivery address and delivery rhythm through the bulk enquiry form.
