Sources: 2. Developments: 2. Turkish authorities have launched a large-scale investigation into the starch-based sugar (NBŞ) sector, targeting 25 companies across multiple provinces including Istanbul, Ankara, and Adana. The probe, coordinated by the Istanbul Chief Public Prosecutor's Office and supported by the Ministry of Agriculture and Forestry and the Tax Inspection Board, focuses on allegations of quota violations, tax evasion, and the forgery of private documents. Investigators suspect companies are bypassing production quotas and domestic sales limits by mislabeling products. Specifically, starch-based sugar is allegedly being invoiced under different names such as ‘maltodextrin’, ‘glucose’, ‘starch’, or ‘fructose’ to hide its true nature. The investigation also includes allegations regarding the trade of spoiled or altered food products. As the probe expands, 47 company managers have been summoned for questioning. The situation reflects broader tensions within the Turkish food market regarding the legal status and market impact of corn-based sweeteners compared to traditional beet sugar production. ## Timeline ### 2026-08-26: Turkey investigates starch-based sugar companies for quota violations Turkish authorities are investigating 25 companies across eight provinces for allegedly bypassing starch-based sugar quotas through mislabeling, tax evasion, and document forgery. 2 sources. https://clstr.news/cluster/turkey-investigates-starch-based-sugar-companies-for-quota-violations ### 2026-08-18: Turkish authorities investigate 25 companies in starch-based sugar sector Turkish authorities are investigating 25 companies in the starch-based sugar sector for quota violations, illegal production, and fraudulent invoicing involving major industrial firms. 5 sources. https://clstr.news/cluster/turkish-authorities-investigate-25-companies-in-starch-based-sugar-sector --- Cite as: Turkish starch-based sugar industry investigation.
