Abstract
Powdered infant follow-up formula plays a crucial role in infant nutrition when breastfeeding is unavailable, insufficient or inadequate. Study aimed evaluated microbiological quality and physicochemical stability of ten samples of available powdered follow-on formulae, in terms of public health collected in Algiers city, Algeria, during spring season. Microbiological analysis, apart from absence of Staphylococcus, Salmonella and Cronobacter, revealed following results: yeasts and molds: present in 40% (4/10); Total Bacterial Count and Sulfito Reducing Clostridia in 30% (3/10), D-Streptococcus and Total Coliform Count in 20% (2/10) of samples. Total Fecal Coliforms and Escherichia coli present in 10% (1/10) of samples, Chemical examinations indicated samples remained stable with following mean values: Density (1.02- 103), pH (6.32- 6,92), Acidity (16.51-18.96), Viscosity (2.43- 2.89), Conductivity (1657- 1827), Protein (1.45-2.33%), Fat (3.63- 5.15%), Lactose (3.55- 6.65%), Total Dissolved Extract (68.78- 86.86%). Samples showed stability chemical throughout storage and, with no packaging or labeling defects noted. However, microbiological quality sample’s fell below Algerian’ standards. In light of these findings, further investigation is warranted through expanded sampling approach, targeting additional brands, conducting a wider array of physicochemical and toxicological tests, and examining a wider of bacterial flora/species.
