Hulled hemp seed – hemp hearts – is the soft inner kernel left when the hard outer shell of an industrial hemp seed is removed. It is a genuinely high-value nutritional ingredient: high in complete protein, high in polyunsaturated fatty acids with a favourable omega-6 to omega-3 ratio, and mild enough in flavour to go into products where a stronger seed would not.
Before any of that matters commercially, the compliance file has to be right. Industrial hemp cultivation in the EU is restricted to approved varieties within a defined THC threshold, and imported hemp products need variety documentation and cultivation authorisation evidence to move without difficulty. Ukrainian industrial hemp is grown under a national licensing regime. A buyer’s first question on this commodity should be about the paperwork, not about the protein content.
Grades, cuts and calibration
Hulling completeness. The primary quality grade, expressed as the percentage of residual shell. Shell fragments are hard, sharp and unpleasant, and they are what a consumer notices immediately. Grades run from a standard commercial level to a premium low-shell grade, and the difference in price is real because the sorting effort is real.
Colour and appearance. Creamy white to pale green kernel. A greyish or dull appearance usually indicates oxidation, and green flecks are residual shell or chlorophyll rather than a defect in themselves.
Oxidation. Hemp kernel is high in polyunsaturated fat, which makes it nutritionally interesting and chemically fragile. Peroxide value and free fatty acids should both be contracted, and the storage regime should be cool. This is not a seed to buy in bulk and hold speculatively.
THC and compliance documentation. Variety declaration, cultivation authorisation and THC analysis on the traded article. Thresholds and the documentary requirements differ between jurisdictions and they change; the requirement here is to name the file, not to restate a number that may not be current at the date of your shipment.
Seasonality and availability
Industrial hemp is harvested for seed in September and October. The seed is dried and cleaned, then hulled through the winter and spring against orders, because hulled kernel has a shorter life than seed in shell.
That is a useful thing for a buyer to know: whole hemp seed stores far better than hulled kernel, so a supplier who hulls to order is selling a fresher product than one who hulls the whole crop in November and sells it through to September. Ask when the lot was hulled, not just when it was harvested.
Ukrainian industrial hemp area has grown with demand from the plant-based and nutrition sectors, and the licensing regime means volumes are documented rather than estimated. Availability is reasonably predictable, and the constraint is usually hulling capacity rather than seed.
What the buyer checks at intake
- Compliance file first: variety declaration, cultivation authorisation evidence and the THC analysis on the traded article. Without this the rest is academic.
- Identity and lot: crop year, harvest date and – critically – the hulling date.
- Residual shell content on a weighed and sorted sample against the contracted grade.
- Colour and appearance against the reference; a grey or dull kernel indicates oxidation.
- Peroxide value and free fatty acids, plus a sensory check. Hemp kernel goes rancid with a distinctive sharp note that is easy to recognise once you have met it.
- Moisture and the microbiological panel.
- Certificate of analysis covering residues and heavy metals, and the packaging integrity on every pack.
Where it is used
Plant-based and health food manufacture is the core market: protein blends, smoothie and bowl toppings, plant milks, energy bars and vegan formulations, where the complete protein profile and the fatty acid ratio are the selling proposition.
Bakery and snacking take hemp hearts into breads, crackers, granolas and bars, generally at modest inclusion because the fat content affects dough behaviour and shelf life. Retail takes them in pouches for direct consumption.
Nutraceutical manufacture takes hulled seed and hemp protein powder into supplements and functional formulations. Cold pressing takes whole seed for hemp seed oil, and the press cake becomes hemp protein flour – which is the outlet that makes the whole crop economic rather than just the hulled fraction.
Standards and routes
Ambient road and sea freight, but with a cool-chain preference that is stronger than for most seeds. The high polyunsaturated content means heat costs shelf life quickly, and a warm container in summer will visibly age a lot.
Barrier or vacuum packaging is the norm for hulled kernel going any distance. A plain paper sack is adequate for a short domestic movement and is not adequate for a container crossing the equator.
The documentation is where hemp differs from every other seed. Variety, cultivation authorisation and THC analysis have to travel with the consignment, and the requirements differ between destination jurisdictions and change over time. Confirm the current position for the destination before the shipment is booked, not afterwards – a hemp consignment held at a border on documentation is difficult and slow to release.
