Pepper is grown across southern and central Ukraine — Kherson, Mykolaiv, Odesa, Zaporizhzhia and Vinnytsia oblasts — as an open-field summer crop, with protected cultivation adding shoulder-season volume around the larger cities. The processing lines sit close to the fields because pepper deteriorates fast once cut.
In frozen form the crop divides into two commercially distinct families that share a name and almost nothing else. Sweet pepper — red, yellow, green and orange bell types — is bought by colour, cut and free-flow behaviour, and ends up on pizza, in ready meals and in vegetable mixes. Hot pepper is bought by pungency and is a seasoning ingredient. The specification, the handling and the buyer are different in each case.
Technically, pepper is the most water-rich item in this wave, and that single fact drives everything downstream: how fast it has to be frozen, how much drip it releases on thaw, how it behaves on a pizza in an oven, and why an underpowered freezing tunnel produces a product that no amount of careful packing can rescue.
Grades, cuts and calibration
Cut formats. Strips at roughly 5 mm to 10 mm width are the volume format, followed by dice at 8 mm to 20 mm, halves and quarters for stuffing and grilling, and rings. Strip length is specified as a band, because a bag of very short strips looks like waste even when it weighs the same.
Colour separation. The single most important commercial variable. Material is sold as single colour — red, yellow, green — or as a defined mix with stated ratios. Colour sorting on an optical sorter is what makes a clean single-colour line possible; a supplier without one will quietly deliver drift in the mix ratio.
Free-flow quality. True IQF pepper pours. Clumping means either a slow freeze, a warm intermediate storage step or surface moisture that was not removed before the tunnel. Buyers assess it by tipping a sample and watching, which is a better test than any certificate.
Pungency for hot lines. Hot pepper is graded on Scoville heat units or, more usefully in a commercial specification, on measured capsaicinoid content. Pungency is a sensory and formulation parameter, not a food safety parameter, and it varies substantially between seasons and between fields of the same variety.
Defects. Seed and placental tissue carry-over, stalk fragments, sunscald, soft or water-soaked pieces and colour drift. Seed count is the defect a pizza buyer notices first.
Seasonality and availability
Field pepper is harvested from July to early October, with red material concentrated in the later part of the window because red is simply green pepper left on the plant to ripen. That is why red always costs more in yield terms: it occupies the field longer, yields less per hectare and is more vulnerable to weather at the end of the season.
Peppers are harvested by hand, in multiple passes across the same field, and go to the line within hours. There is no meaningful raw material storage step: cut pepper loses turgor and colour quickly, so the processing calendar follows the field calendar exactly.
Frozen supply is year round from store. Contracting is season-driven — a buyer negotiating a red pepper programme in spring is negotiating against a crop that has not been planted, and the ratio in a mixed-colour product is the parameter most likely to be renegotiated after a difficult season.
Protected cultivation extends the window at both ends and supplies the fresh trade, but the volumes are not usually the ones that end up frozen.
What the buyer checks at intake
- Colour distribution against the contracted single colour or mix ratio, assessed on a weighed sample
- Strip width and length band, or dice dimension, with the fines fraction capped
- Free-flow behaviour, assessed by pouring a sample from the bag
- Seed and placental tissue count per defined sample weight
- Stalk and calyx fragments, and any extraneous vegetable matter
- Drip loss and texture after a controlled thaw, which reveals the freezing rate used
- Product temperature at the tail lift and a continuous transit temperature record
- Glaze or ice crystal presence, which indicates a temperature excursion in the chain
Where it is used
Pizza and food service. The largest single outlet for strips. The buyer cares about colour, strip geometry, and how much water the pepper releases in an oven, because a wet pepper makes a soggy pizza. Low drip loss on thaw is the proxy specification for that behaviour.
Ready meals and prepared foods. Dice go into stir-fry bases, fajita mixes, sauces and traybakes. Here the specification centres on dice integrity after a reheat cycle and on the colour holding up through a cook step.
Vegetable mixes. Pepper is the colour component of most frozen vegetable mixes and soup packs. It is dosed at a low inclusion rate for visual effect, which makes uniform piece size more important than in a single-vegetable pack.
Roasted and dried formats. Roasted or flame-peeled pepper is a separate premium line with a distinct flavour profile, and dried pepper flake and paprika are ambient products that compete on a completely different logistics basis. Both are covered separately in the processing guide.
Standards and routes
IQF pepper is bulky rather than dense, so loads cube out before they weigh out. Reefer road into central Europe is the standard route, with the set point at minus 18 degrees Celsius or colder, Codex CXC 8-1976 as the handling reference and ATP for the equipment.
Pepper is unusually sensitive to a break in the chain. Its high water content means any temperature abuse recrystallises quickly, welding the free-flowing pieces into a block that cannot be dosed on an automatic line. A load that arrives clumped is a load the customer’s process cannot use, regardless of how it tastes, so continuous logging and a tight tail-lift discipline are not optional here.
