Production And Evaluation Of Two Varieties Of Canned Sweet Corn From Indigenous Species

ABSTRACT

Two varieties of sweet corn (DRM leser yellow and Oba super 4 yellow) were canned using USDA home canning method Proximate, mineral, vitamin, microbial load, sensory properties, starch, sugar, and total carotenoid of canned sweet corn were compared with commercial canned sweet corn. The products had proximate compositions varied from 33.72% to 35.12% for moisture, 3.89% to 3.90% for ash, 2.06% to 2.08% for fibre, 10.42% to 10.62% for protein, 4.395 % to 4.49% for fat, 43.99% to 45.28% for carbohydrate. Mineral content of canned sweet corn varied from 10.69 mg/lO0g to 13.36 mgll0Og for calcium , 8.00mg/100g to 9.60mg/100g for magnesium, 54.03mg/100g to 54.43 mg/100g for phosphorus , 871% to 878% for sodium,123.475to 130.40% for potassium 1.44mg/100g to 2.205 mg/100g for iron. vitamin A ranged from 108.72mg/100g to 112.41 mg/100g ,vitamin C ranged from 11.l2mg/100g toll.73mg/l0Og, vitamin E ranged from 2.02mg/100g to 2.24mg/100g , bacterial load ranged from 17.67 cfu/g to 32.00 cfu/g while, fungi load ranged from 6.33cfu/g to 6.33cfu/g .the result of sensory evaluation based on the nine-point hedonic scale showed that canned sweet had taste 7.05 to 7.30, aroma 6.59 to 7.05, colour 6.85 to 7.60, appearance 7.03 to 7.21, general acceptability 7.10 to 7.11, sugar range from 6.39 to 6.62, starch range from 7.29% to 7.66% , total carotenoid ranged from 211.77g/100g to 215.26jig/100g.
