Response surface methodology and central composite design for K = 3 was used to study the combined effect of blanching time (0-12 min), soaking time (0-24 h) and sodium hexametaphosphate [(NaPO3)(6)] salt concentration (0-1%) on moisture, ash, leached solids, phytates, tannins and hardness (texture) of cowpeas during canning. Regression models were developed to predict the effects of variables on the studied indices. Blanching, soaking and salt concentration all had significant positive effects on moisture content, ash content. leached solids, phytates, tannins and hardness of the canned cowpeas with significant interaction between all the factors with high regression coefficients (72.0-91.4%). The use of blanching and soaking prior to canning led to increasing moisture content and leached solids while significant decreases were observed for phytates, tannins and hardness of the canned cowpeas …
