Hazelnut Quality Inspection in Turkey

Turkey grows roughly two thirds of the world's hazelnuts along its Black Sea coast and supplies most of the global confectionery industry. For buyers, the key questions are kernel quality, aflatoxin, rancidity and, increasingly, social compliance during harvest.

01Product overview

  • Main varieties include Tombul, Palaz, Çakıldak, Sivri, Kara and Foşa
  • Giresun quality refers mainly to Tombul nuts; Levant quality covers other varieties and blends
  • Traded in shell, as natural kernels, blanched, roasted, diced, as meal and as paste
  • Kernel calibres such as 9 to 11, 11 to 13 and 13 to 15 mm

02Turkish production regions

Ordu, Giresun, Samsun, Trabzon, Sakarya, Düzce and Zonguldak.

04Export characteristics

Turkey exports to the EU, especially Germany and Italy, and to many other markets. In-shell nuts are dried, often on open yards, then cracked, graded, and processed further by exporters.

05Typical quality parameters

Quality parameters for Hazelnuts
ParameterWhat is checked
CalibreKernel size distribution by mm
MoistureKernel moisture within contract limits
DefectsRotten, mouldy, insect damaged, shrivelled, doubles, broken kernels
Foreign matterShell fragments, stones, husk
BlanchabilityFor blanched product, skin removal percentage
RancidityFree fatty acids and peroxide value

Limits and tolerances come from your contract and the applicable standard. We do not apply generic values where a contract specification exists.

06Visual inspection criteria

  • Internal mould and discolouration on cut kernels
  • Insect damage (including from hazelnut weevil and stink bugs)
  • Shell fragments
  • Shrivelled and empty kernels
  • Rancid odour

07Sampling methods

Mycotoxin sampling follows Regulation (EC) No 401/2006 or the contract method, with incremental samples taken across all bags or cartons in the lot. Quality is assessed on a separate sample examined for size, defects, moisture and foreign matter.

08Laboratory testing

  • Aflatoxin B1 and total aflatoxins
  • Moisture
  • Free fatty acids and peroxide value
  • Salmonella and E. coli
  • Pesticide residues

Testing is coordinated through laboratories accredited to ISO/IEC 17025 for the required method. See laboratory coordination.

09Food safety and quality risks

  • Aflatoxin, particularly in wet harvest years
  • Salmonella linked to drying on open ground
  • Rancidity in poorly stored stock
  • Social compliance during the seasonal harvest

10Packaging and labelling

Jute or PP bags of 50 kg for kernels, vacuum-packed cartons for processed product.

11Storage and transportation

Cool, dry and preferably cold storage; vacuum packing for roasted and processed product.

12Pre-shipment inspection procedure

  1. Review specification: calibre, grade, moisture, defects and aflatoxin limits
  2. Confirm lot identity, bag or carton count and production codes
  3. Take incremental samples across the lot for the laboratory aggregate
  4. Examine size distribution, defects, shell fragments and foreign matter
  5. Measure moisture and check for rancidity odour
  6. Check packaging, labelling and allergen declarations
  7. Supervise container condition, loading and sealing
  8. Issue an inspection report and attach laboratory results

13Relevant international standards

Regulations are amended regularly. Always check the version in force for your destination market.
