This study was conducted to determine an estimated value and change in TDF (total dietary fiber) binding major minerals (Ca, P, K, Mg) of soybean sprouts depending on cultivation periods of 1, 3 or 5 days, and parts of cotyledon and hypocotyl. The compositions of TDF binding major minerals in soybean sprouts were evaluated by the enzymatic-gravimetric method developed by Prosky and adopted by AOAC. The content of TDF binding P ranged between 915.28 ㎎ and 1037.82 ㎎ per 100 g cotyledon. Average contents of Ca, K, and Mg in cotyledon ranged between 541.67 ㎎ and 634.34 ㎎, 180.91 ㎎ and 253.98 ㎎, 231.90 ㎎ and 301.01 ㎎, respectively, on dry matter basis. The average contents of TDF binding Ca in hypocotyl per 100 g were between 454.36 ㎎ and 540.33 ㎎, and other major minerals contents were between 149.24 ㎎ and 186.21 ㎎ for P, 164.17 ㎎ and 182.78 ㎎ for K, and 152.53 ㎎ and 161.22 ㎎ for Mg, respectively. The proportional changes of Ca, an estimated value in cotyledon, ranged between 5.58% and 30.98%, 47.18% and 59.10% for P, 95.24% and 95.50% for K, and 58.45% and 68.64% for Mg, respectively, based on dry matter. An estimated value of Ca, P, K, and Mg in hypocotyl ranged between 6.71% and 13.52%, 91.03% and 91.76%, 96.91% and 98.92%, and 61.03% and 66.37%, respectively, on dry matter basis.
