چکیده
|
Parkia biglobosa starch was subjected to different heat-moisture treatment (hmt) at different moisture contents (15, 20, 25, and 30%) at 110oc for 16 hours. the content of resistant starch (rs) was the lowest (33.38%) in the untreated native parkia and increased in the samples with hmt-15 (37.79%), hmt-30 (39.64%), hmt-25 (46.63%), and hmt-20 (50.14%), showing significant increase (p < 0.05) in rs following the hmt. there was a reduction in the swelling power and pasting properties of hmt starches, but the solubility of the hmt starches was higher than that of untreated native starch. differential scanning calorimetry and the changes in the x-ray diffraction (xrd) patterns confirmed the effect of hmt on parkia starch. therefore, replacing native parkia with heat-moisture treated parkia starch leads to the development of new products from rsrich powder with high rs levels and functional properties.
