Application Of Response Surface Methodology For Studying The Influence Of Soaking, Blanching And Sodium Hexametaphosphate Salt Concentration On Some Biochemical And Physical Characteristics Of Cowpeas (Vigna Unguiculata) During Canning, Emmanuel Ohene Afoakwa, Samuel Yenyi
Application Of Response Surface Methodology For Studying The Influence Of Soaking, Blanching And Sodium Hexametaphosphate Salt Concentration On Some Biochemical And Physical Characteristics Of Cowpeas (Vigna Unguiculata) During Canning, Emmanuel Ohene Afoakwa, Samuel Yenyi
Professor Emmanuel Ohene Afoakwa
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 …
Response Surface Methodology For Optimizing The Pre-Processing Conditions During Canning Of A Newly Developed And Promising Cowpea (Vigna Unguiculata) Variety, Emmanuel Ohene Afoakwa, Samuel Yenyi, Esther Sakyi-Dawson
Response Surface Methodology For Optimizing The Pre-Processing Conditions During Canning Of A Newly Developed And Promising Cowpea (Vigna Unguiculata) Variety, Emmanuel Ohene Afoakwa, Samuel Yenyi, Esther Sakyi-Dawson
Professor Emmanuel Ohene Afoakwa
Cowpea (IT87D195Y) seeds were canned with the objective of investigating the optimal pre-processing conditions that would yield the best quality canned product from the newly developed cowpea variety. Pre-canning procedures such as blanching time, soaking time and sodium hexametaphosphate [(NaPO3)6] salt concentration were used as the independent variables for a Central Composite Rotatable Design (CCRD). The pre-processing parameters obtained from the CCRD were used for the canning of the cowpeas and the quality characteristics (moisture content, pH of the drained liquid, drained weight, splitting of the seeds, leached solids and seed hardness) of the canned products were studied using response …
