This study was carried out to evaluate the physicochemical, anti-nutrients and microbial load of soybean flour sold from different locations in Awka. Anambra State Nigeria. The eight soybean flour samples obtained were subjected to physicochemical, anti-nutrient and microbial load test using standard methods. The result obtained was further analyzed statistically using one way ANOVA (P > 0.05). The results showed that the physicochemical parameters namely, total titratable acidity ranged from 0.03 - 0.06% with sample FMS having the highest value of 0.06% and the sample NAS having the least value of 0.03%. The viscosity ranged from 19.52 - 22.41Cp and pH 6.45 - 6.75. The FMS sample had the lowest pH value of 6.45 while the sample ARS had the highest pH of 6.75. The anti-nutrient showed that phytate content ranged from 0.60 - 1.04 mg/100g, tannin 1.04 - 1.21 mg/100g, trypsin inhibitor ranged from 4.17-7.33 TIU/g, lectin 3.16 - 4.33 TIU/mg. The functional properties showed that the bulk density ranged from 0.57 to 0.59g/ml and absorption capacity 2.28 - 3.92%. The result for microbial load of soybean flour revealed that the total viable count ranged from 1.33×105 to 3.46×105 and the fungal count ranged from 1.60×105 to 4.53×105. It was observed that soybean flour sample (FMS) possessed low anti-nutrients with good functional properties. Also, it has lower microbial load when compared to other samples. The lowest microbial load recorded could be as a result of proper food handling processes.
