Confectionery sunflower seed is a different crop from the sunflower that goes to the crusher, even though both are Helianthus annuus. Oil-type seed is small, black and bred for the highest possible oil content, and its value is measured in a laboratory. Confectionery seed is bred large, with a lower oil content, a thicker striped hull that separates cleanly, and a kernel that fills the shell; its value is measured with a screen and with the eye. That difference matters commercially because the two crops are not substitutes: a buyer who accepts oil-type seed against a confectionery contract receives a product that cannot be graded to calibre, roasts unevenly and yields a small, oily kernel. Ukraine supplies both, and for the bakery and snack trade the article that matters is in-shell confectionery seed graded on the 64ths-of-an-inch screen, plus hulled kernel in bakery and roasting grades.
Grades, cuts and calibration
In-shell seed is graded by calibre, meaning the fraction that stays on a round-hole or slotted screen measured in 64ths of an inch. The trade shorthand runs from 20/64 upward, and larger is more valuable: 22/64 and above is a snack calibre for roasting and salting in the shell, while smaller grades go to bird feed and to hulling. Specify the screen size, the minimum percentage that must be retained on it, and the maximum admixture below it, because a lot described only as 22/64 can legitimately contain a wide range of undersize depending on the tolerance. Hulled kernel is graded differently: on whole kernel share against broken and split, on colour and the absence of hull fragments and grey or black specks, and on the presence of any residual hull, which in a bakery topping is a customer complaint. Kernel grades in the trade are usually named by application, bakery grade being the highest cosmetic requirement because the kernel sits visible on top of a loaf. Beyond size, the shared parameters are moisture, oil content, damaged and empty seed, and the food safety set. Moisture is the one that decides storage life: confectionery seed is usually contracted at 8 to 9 per cent maximum for in-shell and 6 to 7 per cent for kernel, and a wet lot moulds and develops aflatoxin rather than simply losing condition. Oil content is deliberately lower than oil-type seed, typically in the high thirties to low forties rather than the high forties, and a high figure on a confectionery contract is a sign that oil-type seed has been mixed in.
Seasonality and availability
Sunflower is harvested in Ukraine from the last week of August through October depending on latitude and on the maturity group planted. Confectionery seed is usually harvested at the earlier end and dried carefully, because the cosmetic requirement means a stained or weather-damaged seed loses grade entirely rather than being downgraded a little. Drying is the commercial control point: too hot and the kernel scorches and the hull cracks, which shows up as breakage at hulling and as a bitter note after roasting. After drying and calibration the crop is held in conditioned store and released through the year, so supply is a stock question after November. New-crop calibre distribution is the number to ask for in the autumn, since a dry growing season produces a crop that is sound but skewed to smaller screens, which tightens the large-calibre grades even in a year with adequate total tonnage.
What the buyer checks at intake
- Calibre by screening a declared sample weight on the contracted screen, reporting the percentage retained and the undersize. Do this on arrival rather than accepting a loading figure.
- Moisture on every pallet or on a documented sampling plan, since a single wet section in a container is the mould and aflatoxin risk.
- Whole kernel share, broken and split percentage, and residual hull count for hulled kernel.
- Visual grading against a retained reference sample for colour, stripe definition, staining and insect damage.
- Empty and shrivelled seed percentage, which is a yield question for a roaster and a complaint question for a retail pack.
- Aflatoxin result from an accredited laboratory with the sampling plan named, because the contaminant is highly heterogeneous.
- Pesticide residue screen appropriate to the crop, including any desiccant used before harvest.
- Live insect check and the fumigation record where the lot was fumigated, together with the phytosanitary certificate for the consignment.
Where it is used
In-shell roasted and salted seed is a snack category in its own right across Eastern Europe, the Middle East and increasingly Western European ethnic and health ranges, and it is where the large calibres are consumed. Hulled kernel splits between bakery, where it is a visible topping and an inclusion in seeded breads, crackers and cereal bars, and snack and health food, where it is roasted, seasoned, or sold raw in mixes and as a nut alternative for allergen-restricted ranges. Confectionery uses kernel in brittles, bars and coated products. Smaller and off-cosmetic grades go to bird and pet food and to the crush, which is what gives the grader a commercial outlet for everything the optical sorter rejects.
Standards and routes
Seed and kernel move as palletised bag or carton cargo in dry containers and curtainside trailers, at ambient temperature but away from heat, which shortens kernel shelf life. As a plant product the consignment travels on the plant health route: a phytosanitary certificate where the commodity is listed under Regulation (EU) 2016/2031, a CHED in TRACES NT, and a fumigation record where the lot has been treated. Suppliers into European retail and bakery are normally certified to a GFSI-recognised scheme, with the ready-to-eat roasting step audited separately. See the grain and oilseed export documentation guide for the certificate sequence.
