Akhisar Uslu Olive Oil: oil from a black table cultivar
Registered in 2017. Uslu is principally a table cultivar; the certificate protects its oil separately. β-sitosterol sits in a very narrow 87.36-87.39% band.
Uslu is one of Türkiye's best-known black table cultivars. Its oil is secondary. This registration protects it as a product in its own right.
The record
| Registration no | 1056 |
| Protection from | 10.11.2017 |
| Type | Geographical indication |
| Registered by | Akhisar Chamber of Commerce and Industry |
| Area | Akhisar, Gölmarmara, Salihli, Turgutlu, Saruhanlı and Kırkağaç in Manisa |
| Raw material | Akhisar Uslu Olive (registration no 165) |
Its raw material is registered: the measured oil content of the Uslu olive is 21.50%.
Sterol profile
| Sterol | Value |
|---|---|
| β-sitosterol | 87.36 – 87.39% |
| Delta-5-avenasterol | 4.93 – 5.16% |
| Clerosterol | 0.94 – 0.97% |
| Sitostanol | 0.87 – 0.90% |
| Delta-5,24-stigmastadienol | 0.53 – 0.62% |
| Delta-7-avenasterol | 0.60 – 0.61% |
| 24-methylene cholesterol | 0.13 – 0.16% |
| Campestanol | 0.12 – 0.16% |
| Cholesterol | ≤ 0.5 |
| Brassicasterol | ≤ 0.1 |
| Total β | ≥ 93 |
| Total sterols | ≥ 1000 mg/kg |
| Erythrodiol + uvaol | ≤ 3.0 |
The β-sitosterol range spanning only 0.03 of a point — 87.36-87.39% — is striking, and shows how consistent the measurement proved.
Quality limits
| Criterion | Value |
|---|---|
| Peroxide value | ≤ 20 |
| Free acidity | ≤ 0.8 |
Its twin, Akhisar Domat Olive Oil, sets narrower limits on both (≤17 and ≤0.65). The difference follows from the oil character of the two cultivars.
Four registrations, one chamber
The Akhisar Chamber of Commerce and Industry holds four olive registrations: Uslu Olive (165), Domat Olive (166), Domat Olive Oil (1055) and Uslu Olive Oil (1056). The table and oil lines of two cultivars, each protected separately — few registration sets in Türkiye are this systematic.
