ANALYTICAL VALIDATION OF CYANIDE DETECTION LIMITS IN Gethuk: IMPLICATIONS FOR FOOD SAFETY AND PUBLIC HEALTH
Gethuk, a traditional Indonesian staple made from cassava, poses potential health risks due to naturally occurringcyanogenic glycosides. While traditional processing is known to reduce toxicity, empirical validation of detectionlimits in specific food matrices remains critical for ensuring food safety. This study aims to fill the researchgapregarding the sensitivity of the complexometric titration method in monitoring cyanide levels in Gethuk, specificallyevaluating its effectiveness against national safety standards. Qualitative analysis was conducted using the picratepaper test, while quantitative assessment utilised a modified Deniges complexometric titration. The results indicatedthat cyanide was not detected in any samples, with levels remaining below the method’s limit of detection (LoD) of 14.43 mg. However, the high LoD relative to the Indonesian National Standard (SNI) of 1 mg/kg reveals asignificant methodological limitation for trace analysis. These findings underscore the urgent need for moresensitive analytical techniques to ensure public health safety. By evaluating food safety through analytical validation, this research directly contributes to Sustainable Development Goal-3: Good Health and Well-being, providingafoundation for improved monitoring of traditional food products to mitigate chronic toxicological risks
