NUTRIENTS AND ANTI-NUTRIENTS CONTENT OF DEHULLED SOYBEAN

The nutrient and anti-nutrient contents of dehulled soybean were investigated, using proximate composition , amino acid profile, mineral, micronutrient and anti-nutrient values. The soybean was boiled for 10 minutes, dried, dehulled and milled into a fine flour. The dehulled soybean (DSB) had high value for protein and fat (49.38 and 25.97g/100g respectively). The carbohydrate content of the DSB was very low (12.89g/100g). Leucine and glutamic acid were the most abundant essential and non-essential amino acids (6.62 and 16.25g/16g N respectively). The sulphur containing amino acids methionine and cystine were 1.22 and 2.09g/16g N respectively. The DSB is a good source of phosphorous (1193.3mg/100g). It had almost equal amount of calcium and magnesium (17.5 and 17.3 mg/100g respectively). It was a good source of thiamin (408.0mg/100g), riboflavin (394.1mg/100g) and niacin (603.0mg/100g).The DSB had very high level of trypsin inhibitor (2786.00 TIU/100g). The tannin and phytate content were 34.92 and 42.00mg/00g respectively. The dehulled soybean was found to have high nutritional values but was underscored by its high anti-nutrients; trypsin inhibitor (2786.00 TIU/100g). tannin (34.92mg/100g), phytate (42.00mg/100g), oxalate (27.62mg/100g) and saponin (34.60mg/100g)
