The study aimed to investigate the effect of heat treatments on the proximate composition, caloric value, carbohydrate profile and physicochemical characteristics of Adlai and Obatanpa cross Lagkitan corn variety (OxL). Different percentages of Adlai were incorporated to OxL corn and sensory evaluation revealed that 90% adlai: 10% OxL corn blend was the most acceptable proportion. The raw, boiled and canned pure adlai, pure OxL corn and the most acceptable adlai-corn blend were used in the study. Results showed that after boiling, all samples fell under the soft gel consistency category (65-100 mm) and have a high gelatinization temperature (>74°C). In adlai, OxL corn and adlai-corn blend samples, values of moisture and crude fat increased significantly (p<0.05) from raw to heat-treated samples (boiling and canning), while those of crude protein, crude fiber, total ash and carbohydrate significantly decreased (p<0.05). The energy content (kcal/100 g) was highest in all raw samples while boiling and canning led in a significant (p<0.05) decrease. Moreover, there is a significant (p<0.05) reduction in starch and amylose content of all raw samples after boiling and further decreased by canning. However, the values of moisture, crude fat, total ash, carbohydrates, caloric value, starch and amylose for boiled and canned samples were not significantly (p>0.05) different. Overall, heat treatment significantly reduced the nutritional value of adlai, OxL corn and adlai-corn blend.
