Green lentil is bought for the opposite reason to red lentil. Where red lentil is prized for disintegrating, green lentil is bought because it holds together: the seed coat stays on, the cotyledons stay joined, and a properly cooked green lentil keeps a discrete, slightly firm bite. That single functional difference drives every specification decision in the line.
Ukrainian green lentil is grown mainly in the forest-steppe and northern steppe, with Kirovohrad, Poltava, Kharkiv and Vinnytsia oblasts carrying most of the commercial area. It sits in rotation with cereals and oilseeds, which is agronomically useful and commercially inconvenient: rotational area moves with relative returns, so green lentil supply is more variable year to year than a dedicated crop would be. The rotation and seasonality guide explains how that plays out for a buyer planning volume.
Because the seed coat remains, green lentil undergoes no dehulling. The processing chain is cleaning and selection only, which means the raw material quality has nowhere to hide. A lot with weathered, stained or insect-damaged seed will show it, and the colour sorter can only remove those units, not repair them.
Grades, cuts and calibration
Green lentil is graded on calibre, colour and defect counts, and calibre is the parameter that most affects how the lot behaves in a kitchen.
Calibre. Expressed as a screen size in millimetres. Larger calibres are visually preferred in salads and retail packs and cook a little slower; smaller calibres cook faster and are favoured in ready meals where a compact lentil disperses better through a sauce. Neither is a quality statement.
Colour. Green lentil colour runs from pale green through to a deeper, mottled green depending on variety and weathering. Uniformity matters more than the shade itself, because a mixed lot looks like a blend even when it is not. Specify against a physical reference.
Defect counts. The commercial defects are broken and split seed, seed-coat damage, insect-damaged seed, discoloured and weathered seed, and other-species seed. Each should be stated against a defined sample mass with an ISO 605 method reference.
The processing sequence is cleaning on air-screen equipment, destoning on a density table, calibre screening, colour sorting, then metal detection and packing. Some packers add a polishing pass for a brighter surface; it improves shelf appearance and does nothing else.
Stone detection deserves separate attention in green lentil, because the seed is close to stone density and gravity separation is correspondingly less decisive than it is in larger pulses.
Seasonality and availability
Sown in spring, harvested in July and August, stored dry and shipped year round. Availability within a marketing year is a stock question; availability between years is a rotation question.
That rotation exposure is the practical planning issue. Green lentil competes for spring-sown area with sunflower, maize, soybean and other pulses, and the planted area responds to expected returns. A buyer contracting a fixed annual tonnage without a conversation about area is contracting against a variable they cannot see. Buyers who need certainty either contract early, before sowing decisions are finalised, or carry a second origin.
Weather at harvest determines the grade mix rather than the volume. A dry finish gives clean, bright, well-filled seed; rain at maturity produces staining, seed-coat splitting and sprouting damage, all of which the colour sorter removes at the cost of yield in the premium grades. In a wet year the top calibres and colours are genuinely scarce, and a buyer holding a specification written in a good year will find nothing that meets it.
What the buyer checks at intake
- Moisture against the contract figure, with the reference method named. A lot shipped wet will heat in the container and arrive with mould and a smell that no downstream cleaning removes.
- Foreign matter, split and broken counts, and stones, each against a defined sample mass and a named method rather than a bare percentage.
- Insect activity, live and dead, plus evidence of the storage regime. This is the single most common rejection cause in the pulse trade.
- Colour uniformity and off-colour count, assessed under a defined light source rather than on a warehouse floor.
- Odour. Dry pulses pick up taint readily, and a musty or chemical smell at intake is a fatal defect regardless of the analytical results.
- Calibre verification on a screen against the contracted size, with the tolerance stated. Calibre drift between sample and shipment is a recurring dispute in lentil.
- Seed-coat integrity. Split and damaged coats predict disintegration in cooking, which defeats the reason green lentil was bought.
- Cooking behaviour under an agreed protocol, assessed for shape retention rather than only for time.
Where it is used
Ready meals and prepared salads. The outlet that defines the product. A green lentil in a chilled salad has to be individually recognisable, tender but intact, and consistent across the pack. Shape retention after cooking is the whole specification.
Canning. Canners need seed that survives retorting without breaking up and that takes up water predictably. Seed-coat integrity at intake predicts performance in the can better than any other single check.
Food service. Bulk bags into catering and institutional kitchens for soups, stews and side dishes. Reliability and freedom from stones matter more than cosmetic grade.
Retail packing. Consumer packs, frequently private label, where colour uniformity and calibre consistency are the visible quality signals. See the private label setup guide for how these arrangements are structured.
Sprouting. A small but real outlet. Sprouting requires viable seed, which means the drying and storage history has to have preserved germination, and it carries a distinct microbiological risk profile that a standard dry pulse specification does not address.
Standards and routes
Codex CXS 171-1989 supplies the definitions and quality factors; ISO 605 supplies the methods. Contracts that name both are enforceable in a way that contracts quoting bare percentages are not.
Residues fall under Regulation (EC) No 396/2005 and contaminants under the limits consolidated in Regulation (EU) 2023/915; work from the current consolidated texts. Plant protection product approvals themselves sit under Regulation (EC) No 1107/2009, which is worth knowing because an active approved in the origin country is not necessarily one with a tolerance in the destination. Hygiene requirements under Regulation (EC) No 852/2004 apply to the packing site, and contact materials under Regulation (EC) No 1935/2004 to the bags.
Movement is ambient. European destinations go by road; Turkish, Middle Eastern and North African destinations by sea from the Black Sea corridors. Wood packaging, where used, is treated and marked under ISPM 15. For sprouting- grade material the chain has additional requirements and should be contracted separately rather than as a variant of a food specification.
