Abstract
This study investigated the effects of different dying temperatures on the quality of tomato powder. The drying temperature were 65°c. (AOA), 70°c (BOB) , 75⁰c (COC), 80⁰c (DOD) and the control (commercial tomato powder, EOE). The chemical, functional and mineral content of the tomato powder were determined. For the chemical properties: the moisture contents ranged from 5.90 to 6.48%, fat from 3.61 to 3.85%, Ash from 6.24 to 6.59%, protein from 5.97 to 9.89%, carbohydrates from 65.58 to 69.57%, for the functional properties: bulk density ranged from 0.21 to 0.31g/cm³, foam capacity from 0.10 to 2.13%, emulsion capacity from 2.02 to 2.14%, PH from 6.01 to 6.18, wettability from 5.69 to 10.48secs, WAC from 2.47 to 3.21g/g, OAC from 1.20 to 1.38g/g. For the mineral content: magnesium ranged from 108.21 to 114.14mg/100g, calcium from 74.08 to 75.11mg/100g. This study revealed that the higher the drying temperature, the lower the nutritive value.
