role in metabolism or construction of body. Organic iron from various sources
for curing iron-deficiency anemia was one of the hot research items in recent
years. The aim of this study was optimize the enzymatic hydrolysis conditions
for preparing iron peptides from shrimp processing byproducts. Factorial experiments
and response surface methodology were applied to optimize the enzymatic hydrolysis
parameters. The iron binding capacity was used for evaluating indicator. The
results showed that trypsin hydrolysate of shrimp processing byproducts had
the highest iron binding ability and the three significant factors were enzyme
concentration, pH and hydrolysis time, respectively. The optimum trypsin hydrolysis
conditions were pH 8.2, enzyme concentration of 500 U mL-1 and hydrolysis
time of 2 h, respectively. The highest iron binding ability of trypsin hydrolysate
was obtained to be 6.75 μg mg-1 at these optimum conditions.
Trypsin was effective for producing iron binding peptides from shrimp processing
byproducts.]]>Bao, X.L., M. Song, J. Zhang, Y. Chen and S.T. Guo,20071811151118Begum, S., K. Ikejima, H. Ara and M.Z. Islam,2006613071313Byun, H.G., J.K. Lee, H.G. Park, J.K. Jeon and S.K.
