3.3. Image analysis
The results of the seven features evaluated in image analysis for pound cakes baked in microwaves and conventionally are shown in Tables 4 and 5. ANOVA indicates that only in the following three features significant differences (P 0.05) were detected: average cell area, total cell area and total cell area ratio. The two cycle microwave baking oven produced larger cells (average cell area of 0.74 0.06 vs. 0.63 0.03 mm2) and therefore a larger total cell area (540 42 vs. 463 22 mm2). Also for conventional baked the cell to total area ratio and mean cell area showed a lower standard deviation (0.03 and 0.02 respectively) in comparison with the microwaved results (0.06 and 0.04); this fact indicate that the size and uniformity of cells were more homogenous for conventional baked products.
