The Biological and Chemical Ameliorative Effects of Bread Substituted with Dried Moringa Leaves

Abstract

This study conducted to evaluate the effect of additional dried moringa leaves on bread and their effects on the chemical and biological of rats fed it. Wheat flour with dried moringa leaves powder (DMLB) is used at different levels (6 and 9%) to produce moringa bread. We performed a sensory evaluation of wheat bread substituted with dried moringa leaves, chemical properties (approximate composition and antioxidants), microbiology (total bacteria, spore-forming bacteria, fungi, and yeast) and biological analysis (Triglycerides, total cholesterol, HDL and LDL, ALT, AST, urea, creatinine). Therefore, histopathology examination for kidney and livers of male albino rats fed fortified bread with dried moringa leaves compared with the control sample. The results of the approximate analysis showed significant differences by adding moringa leaves and the percentage of ash, protein, fat, and fiber increased with the moisture content. Moreover, carbohydrates decreased from fortified bread with dried moringa leaves compared to the control sample. The best treatment was fortified bread with 6% dried moringa leaves for all sensory evaluations compared to the other samples and moringa bread (DMLB 9%) helped reduce the microbial load during storage. The effect of moringa bread on liver cirrhosis was evaluated in rats induced by carbon tetrachloride CCl 4 . We found out that the effect of moringa leaves on liver and kidney functions in a state of improvement, as for high-density lipoprotein (HDL) and low-density lipoprotein (LDL), the proportion of LDL was less than HDL compared to the control sample. At the same time, moringa leaves have a significant effect on reducing cholesterol, triglycerides, urea, and creatinine in the serum of rats, which may be attributed to the presence of biologically active plant components. It can be concluded that moringa leaves can improve biological and histological of rats feed it.
