On April 29, 2026, the Ministry of Agriculture and Forestry of Türkiye published Official Gazette No. 2026/14, introducing amendments to the national standard for edible vegetable oils. The revised regulation entered into force immediately upon publication.The amendment updates analytical and compositional specifications for certain edible oils, particularly sunflower oil and hazelnut oil.
Major Key Updates
1. Revision to Fatty Acid Composition Limits for High Oleic Sunflower Oil
Under Annex 1, concerning the determination of fatty acid composition by gas chromatography:
The specification for palmitoleic acid (C16:1) was revised from: “TED–0.1” → “TED–0.2”
The permitted range for stearic acid (C18:0) was revised from:2.9–6.2% → 1.9–6.2%
These amendments apply specifically to high oleic sunflower oil specifications.
2. Revision to Sterol Composition Limits for Hazelnut Oil
Under Annex 4, relating to plant oil sterol composition tables:
The allowable range for δ-5-avenasterol in hazelnut oil was revised from: 1.0–5.1% → 1.0–7.0%
Categories Affected
High oleic sunflower oil
Hazelnut oil
Vegetable oil manufacturers and refiners
Importers and exporters of edible oils
Laboratories conducting fatty acid and sterol composition testing
The updated specifications may require:
1.Revalidation of analytical testing parameters
2.Review of product specifications and certificates of analysis
3.Compliance updates for imported and domestically produced edible oils
The amendments also provide updated compositional tolerances aligned with evolving production and analytical standards within the edible oils sector.
