Microbial Safety And Quality Evaluation Of Soybean Powder In Umuahia Abia State (Nigeria) Major Markets

ABSTRACT

Soybean powder (CP, OR, NM, UM, and Cl) from different processors in Umuahia Abia State were purchased in Umuahia main markets and major centre's were soybean is sold in Umuahia. Analyses were carried out on these samples to determine their safety and quality. Among analysis carried out include proximate, Anti-nutrients, vitamins, minerals, and microbial analysis. The results obtained from the proximate analysis show that the soy powder (CP, OR, NM, UM, and Cl) are higher in Fat/oil, Carbohydrates, Fibre and Ash with the values, 20.08-23.60%, 30.52-63.14%, 3.20-3.72%, 4.86-5.92% respectively. The soy samples were also higher in vitamin A (21.75-32.92tg/g). it was observed that the phosphorus contents of soy bean powder are higher than other minerals with values(4.52- 4.90(mg/100g)). The level of Tannin (1.5lmg/100g) and Trypsin inhibitors(1.57mg/100g) are higher in the soybean powders than Haemaglutin and Phytates. Different microbial analysis where carried out on the soy powders such as Escherichia coil, Yeast and Mould, and Staphylococcus aureus , which yeast and Mould and E.coli are higher with values (1.9x105-3.8x105and 2.010- 5.3x105cfu/g) respectively.
