Hazelnut is the confectionery industry’s structural nut. It is the base of praline and gianduja, the standard inclusion in chocolate bars, and the raw material for the nut pastes that sit behind a large part of European sweet manufacturing. That means the specification conversation is unusually technical, because the customers are unusually technical.
Ukrainian hazelnut is a growing rather than an established origin. Plantation area has expanded significantly in the western and central oblasts over the past decade and the crop is young, which means volumes are rising and consistency between seasons is still improving. It suits buyers who want a European alternative to the dominant Turkish supply and who are willing to work with a supplier on specification rather than buying to an established origin standard.
Grades, cuts and calibration
Calibre. Graded in diameter bands, commonly 9 to 11 mm, 11 to 13 mm and 13 to 15 mm. Larger kernels go whole into visible applications and command a premium. Smaller kernels go to paste, chopping and flour, where size is irrelevant. Specify the band and the in-band percentage.
Natural or blanched. Blanching removes the skin by a short heat treatment followed by mechanical rubbing. It gives a paler, milder kernel with no bitter skin note, which is what most praline and white chocolate applications need. It costs money, it loses weight, and it slightly shortens shelf life by removing a protective layer. Natural kernel keeps the skin and suits roasted, chopped and rustic applications.
Aflatoxin. The regulatory pressure point for this commodity. Aflatoxin is heterogeneously distributed – a single contaminated kernel in a tonne can carry the whole result – so the sampling plan is more important than the analytical method. Commission Regulation (EU) 2023/2782 sets out the sampling requirements.
Defect. Shrivelled, mouldy, insect-damaged and double kernels, plus shell and skin fragments on a blanched grade. Blanched kernel is judged much more harshly on residual skin than natural kernel is on anything.
Seasonality and availability
Harvest runs from mid-August into September, with the nuts dried in shell and then cracked and graded through the autumn and winter. New-crop kernel reaches the market from October.
Because the Ukrainian plantation base is young, yields are still rising year on year as trees mature, and the size distribution shifts with them – a young orchard produces a smaller average kernel. A buyer contracting a large calibre band should confirm availability rather than assume it.
World hazelnut pricing is set by the Turkish crop, which dominates global supply, and a frost in the Black Sea growing region moves the price of Ukrainian kernel immediately. Buyers taking Ukrainian origin for supply diversification should understand that they are diversifying the supply chain, not escaping the price index.
What the buyer checks at intake
- Identity and lot: crop year, calibre band, natural or blanched, production date and the establishment approval number.
- Calibre distribution on a sieved sample against the contracted band and in-band percentage.
- Skin removal completeness on blanched grades. This is where a blanched lot is accepted or rejected.
- Defect count – shrivelled, mouldy, insect damaged, doubles – and moisture across several packs.
- Peroxide value and free fatty acids, with a sensory check for rancidity.
- Aflatoxin certificate with the sampling plan documented, not just the result. The plan is the evidence; the number is the output.
- Vacuum integrity on every pack and the certificate of analysis against the full specification.
Where it is used
Confectionery is the dominant outlet. Praline, gianduja, nut pastes, chocolate inclusions and filled bars all run on hazelnut, and the calibre and blanching specification follow directly from whether the kernel will be visible, chopped or milled to paste.
Bakery takes whole, chopped and ground kernel into cakes, biscuits, pastries and fillings. Ice cream and dairy take paste and chopped kernel, where a stable, well-controlled paste is far more important than the calibre it came from.
Snacking and retail take roasted and salted whole kernels, generally in the larger bands, and here appearance and uniformity are the purchase driver. Hazelnut oil and flour take the mechanical rejects and the smallest fraction, which is the outlet that lets a grading line balance its yield.
Standards and routes
Ambient road and sea freight in vacuum packs. As with walnut, temperature is what consumes shelf life, and blanched kernel is slightly more exposed than natural kernel because the skin that protected it has been removed.
Aflatoxin documentation is the item that determines whether a tree nut consignment clears an EU border smoothly, and hazelnut is among the commodities that receive close attention. The sampling plan documentation should travel with the consignment, not be produced afterwards on request.
Vacuum integrity through the whole journey is what the ambient route depends on. A pallet that arrives with a proportion of soft packs has lost the oxygen barrier on those packs, and they should be treated as a separate, shorter-life stock rather than mixed back in.
