Nutritional Evaluation of Turnip Powder in Cereal Blends: A Study on Wheat, Oats, and Turnips

Abstract

This study aimed to evaluate the nutritional enhancement of wheat-oat blends by incorporating turnip powder at varying concentrations (10%, 20%, 30%, 40%, and 50%). The research assessed the impact of these blends on key nutritional components, including moisture, protein, fat, fiber, calcium, phosphorus, iron, and potassium. The wheat-oat-turnip blends were prepared and analyzed using standard nutritional methods, including proximate analysis and mineral content measurement. Results showed that increasing the concentration of turnip powder led to significant changes in moisture, protein, fat, fiber, and mineral content (p < 0.05). Notably, calcium levels were significantly higher in blends with higher turnip powder concentrations, while other minerals, such as phosphorus and potassium, showed a decreasing trend. Sensory evaluation revealed that a 30% turnip powder blend was most preferred in terms of appearance, aroma, flavor, texture, and overall acceptability. This study demonstrates the potential of incorporating turnip powder into cereal-based products to improve nutritional profiles while addressing dietary gaps.
