Abstract
|
|
|
|
This study was performed to evaluate contents and estimated availabilities of major minerals (Ca, P, K, Mg) in soybean sprouts. Two different sampling parts (cotyledon and hypocotyl), and three culture periods (1, 3, and 5 days) were evaluated. Results indicated that Mg (99.11%) from cotyledon for 5 days culture period was significantly higher than Ca (98.34%), P (97.67%), and K (98.70%). Percent average Mg estimated availability of 5 days cultured hypocotyl was also significantly higher than that of Ca (77.79%), P (91.91%), and K (96.80%). Therefore, the current results indicate that decreased Ca estimated availability in hypocotyl was time dependent and the cotyledon may be the better source for the estimated availability of major minerals than the hypocotyl of soybean sprouts because more than 90% of the major minerals was estimated availability.
