The comparison of baby industry food with home-made food in male rats

Background and Aim: Evaluation of the quality of food proteins has a great importance because of biological and economical impacts. Among existing methods, true Protein digestibility, net protein ratio and protein efficiency ratio have been suggested as appropriate methods to determine the quality of proteins. Considering the importance of protein quality in foods, this study has been conducted to compare the value protein Cerelac (food industry baby) with home made food (Rice -Bean mixed) in male rats. Materials and Methods: This experimental study was performed on 64 male rats (wistar), aged 21 days under 8 diets in 8 groups including of: 2 case diets (home made food and Cerelac), 1 diet standard (casein + Methionine) and 1 basal diet (protein free) in order to determine TPD, AD and 2 case diets, 1 standard diet and 1 basal diet in order to determine NPR, PER and FER. Comparison of TPD, AD, NPR, PER and FER between the groups was analyzed by ANOVA and Tukey methods. Results: TPD were 92.8±4, 87±8 and 79.7±1.6, NPR were 4.3±0.4, 4.3±0.9 and 3.8±0.6 and PER were 3±0.2, 2.5±0.4 and 2.9±0.2 for Casein + Methionine, Cerelac and home-made food groups respectively. So difference TPD ANOVA between three groups was significant (p<0.0001) but NPR and PER were not significant. Conclusion: TPD and NPR are home-made food based on Rice -Bean mixed in comparison with cereal in protein was higher and it is acceptable.
