Title: Biochemical Studies on Weaning Foods Based on Legumes and Caroots
Author: Nabag, Fatima Omer
Abstract: Attempts were made to utilize available food sources on formulation of weaning foods. Common legumes (chick pea and pigeonpea) were used as protein source. While dehydrated carrots powder were used as a vitamin A source. Addition of 25% chick pea or pigeonpea increased the protein content of the weaning foods to 16.7% and 14.4%, respectively, while cerelac and Riri gave protein content of 15.3% and 7.3%, respectively. Incorporation of carrots at 10% level gave a vitamin A content of 564 RE/ 100g material. Weaning food containing chick pea recorded higher preference among panelists and significantly better (p≤0.05) than samples containing pigeonpea. The bulk density of newly developed based formulae cp3, pp3 (0.7 g/ml, 0.8g/ml, respectively) was higher than the market weaning foods cerelac and Riri (0.6 g/ml and 0.5 g/ml, respectively). The formula cp3 recorded lower hot paste viscosity (3500 cp.) than both values obtained for cerelac (4500 cp.) and Riri (extremely viscous). The lysine content of cp3 (3.9g/100g protein) was higher than respective values in market foods and for better when calculated per waeaning material (0.65g/100g material) compared to the other products (0.57; 0.28g/100 material of cerelac and Riri, respectively). Chick pea- based formula (cp3) was also found to possess higher in-vitro protein digestibility (95.2%) compared to cerelac (94.2%) and Riri (88.5%). The calculated protein efficiency ratio (C-PER) of cp3 (1.7) was higher than that of Riri (1.6) and than that of cerelac (2.7).
