The physico‐chemical properties of gari samples produced in South‐Western Nigeria were investigated following standard methods. The results show that moisture content, ash, crude fibre, cyanide content, and total acidity of the gari samples were in the range of 5.59–17.09%, .48–2.59%, 0.27–5.14%, 0.016–0.073 mg/kg, and 0.003–0.22%, respectively. Swelling index and particle size ranged from 2.04 to 2.80 and 0.343 to 0.577 mm, respectively. Nine of the sixty gari samples collected conform to Codex Alimentarius Standard for gari. However, all the samples conformed to the standard in terms of cyanide and total acidity. Classification by Codex Alimentarius Standard showed that 88.3% of the samples were ungraded, while 11.7% were coarse grained. The Nigerian Industrial Standard revealed that 68.3% of the samples were medium coarse grained gari, while 31.7% were fine grained. Based on the foregoing, an appropriate technology profile was proposed with the view to standardize the quality of gari produced in South‐Western Nigeria. PRACTICAL APPLICATIONS: The physico‐chemical properties of gari in south western Nigeria vary from one place to the other due to differences in the method of processing. This inconsistency is affecting local and international gari trade to a large extent in south western Nigeria where the bulk of world's gari comes from. The recommendation of an appropriate technology for gari processing in this work is with the view to standardizing gari quality wherever it processed notwithstanding.
