Golden Sella, White Sella, Steam or Raw Basmati: What Processing Changes

This guide explains how raw, steam, white sella and golden sella basmati are made, and what each process does to colour, cooking, aroma and storage. Use it to choose the right processing for your customers and to read offers that quote the same variety four different ways.

Same paddy, four products

Raw, steam, white sella and golden sella can all come from the same variety, for example Pusa Basmati 1121. The difference is what happens to the paddy before it is milled.

Raw basmati

Raw basmati is the traditional product. Paddy is dried to milling moisture, husked, milled, polished and sorted. It is then aged in storage, often for many months, because aged basmati cooks drier and elongates better.

Strengths: best aroma, whitest colour, soft and fluffy texture.

Weaknesses: raw grains break more easily in milling and in the pot. Cooks must manage water and time carefully. Fats in the bran layer that remain after milling can slowly turn rancid in hot storage.

Best for: retail packs for home cooking, UK and European retail, premium aromatic packs.

Steam basmati

Steam basmati sits between raw and sella. The paddy gets a short steam treatment, at some mills after a brief soak, and is dried before milling. The exact process varies by mill. The steaming partly sets the starch, which toughens the grain.

Strengths: fewer broken grains than raw, firmer cooking, good colour and most of the aroma. Many kitchens find it more forgiving than raw.

Weaknesses: slightly off-white compared with raw. Some aroma is lost.

Best for: restaurants, takeaway and retail buyers who want white rice that holds its shape.

Sella (parboiled) basmati

Sella is the trade name for parboiled basmati. The process has three steps:

1. Soak the paddy in water, often hot water, so the grain absorbs moisture.
2. Steam the wet paddy so the starch inside gelatinises.
3. Dry the paddy back to milling moisture, then husk, mill and sort.

Gelatinisation fuses the starch into a hard, translucent mass. FAO notes that parboiled rice cooks to firmer, less sticky grains that clump less and resist breaking apart. It also takes longer to cook, which is why many cooks soak it first.

White sella or golden sella?

The colour depends on how hard the heat treatment is. FAO describes parboiled rice as cream to yellow, with depth of colour depending on heat severity. Mills adjust soaking temperature, steaming time and pressure to aim for one end or the other.

• White sella: milder treatment, creamy white grain, closer to steam basmati in appearance.
• Golden sella: stronger treatment, golden grain, the hardest and most separate when cooked.

Strengths of both: very low breakage, grains stay separate in large batches, and cooked rice holds well when kept hot for service. Parboiling also hides chalkiness, because chalky areas become translucent.

Weaknesses: less aroma. FAO notes that parboiling drives off volatile compounds. Longer cooking time and more water are needed.

Best for: Gulf food service (biryani, kabsa, mandi), hotel buffets, catering, and large-family retail packs in the Middle East.

How processing changes the spec sheet

Processing changes how some lines on a spec sheet should be read.

• Colour. For sella, uniform colour across the lot matters more than whiteness. Agree a colour reference sample. Mixed golden and pale grains in one lot look poor in the pot.
• Discoloured grains. In sella, "discoloured" means grains darker than the rest, including dark or spotted grains caused by uneven steaming. Ask for a sortex pass after parboiling.
• Chalky grains. Important for raw and steam. Less relevant for sella.
• Elongation. India's new FSSAI basmati standard, applying from August 2023, sets a minimum elongation ratio of 1.7 for non-parboiled milled basmati and 1.5 for parboiled. Expect sella to elongate a little less than raw of the same variety.
• Broken. Sella and steam should run lower broken than raw from the same paddy.

Shelf life and storage

All four store well if kept cool, dry and away from pests. There are differences.

• Rancidity. FAO notes that parboiling inactivates lipase and lipoxygenase, the enzymes behind rancid flavours in milled rice. Sella therefore tends to keep its flavour longer in hot warehouses.
• Insects. A harder, gelatinised grain is often said to resist insects better. FAO points out that parboiled paddy can still be attacked, so storage hygiene and fumigation of sea cargo still matter.
• Moisture. Parboiled paddy must be dried properly. If it is dried unevenly, grains can fissure and break in milling. Check moisture on arrival as you would for raw rice.
• Aroma over time. Raw basmati's aroma fades slowly in storage. Buyers selling on aroma should watch crop year and packing date.

Choosing for your customers

If your customers are unsure, cook all four side by side using their recipe. The differences in colour, firmness and smell are obvious in one test.

Before you order

• State the processing type exactly: raw, steam, white sella or golden sella
• For sella, agree a colour reference sample
• Ask for the cook test method and result (cooked length, firmness, stickiness)
• Set limits for broken and discoloured grains suited to the processing
• State crop year and packing date
• Confirm fumigation for sea cargo and moisture at loading
