The aim of this research is to assess and investigate the iodine content of Akwana local salt collected from Akwana area of Taraba State, Nigeria and trademarked salt in the market and to determine the effect of heat on the salts. This study revealed that Akwana mineral salt obtained from the mining pond (sample A) popular called “Akwana salt” naturally contained 116.10±0.08 mg/kg of iodine concentration as compared with the trademarked salts purchased from Wukari market, sample F (Uncle palm) and sample E (Mr Chef) which have 116.30±0.13 mg/kg and 116.10±0.08 mg/kg, respectively. Sample C (Akwana mineral salt raw filtrate obtained from the local factory in Akwana town) has 71.90±0.08 mg/kg iodine concentration while the least concentrations of iodine are found in sample B (Akwana mineral salt raw sample obtained from the local factory) and D (finished fused Akwana salt sample obtain from the local factory in Akwana town) contained 57.00±0.08 mg/kg and 13.60±0.13 mg/kg, respectively. The re-engineered particle size of Akwana salt had 11.8713 gm, 12.6449 and 13.9519 gm of iodine with comparable texture and particles as fine as the trademarked salt purchased from the market.
