| dc.description.abstract | This study aimed to investigate the effects of rosemary extract (RE) addition on the starch digestion and antioxidant properties of extruded pet foods. Pet foods were extruded using rice, round pea (RP), and wrinkled pea (WP) flours as the sole starch sources with RE incorporated at levels of 0 (control), 1.0, 10.0, and 30.0 g/kg (RE0, RE1, RE10, and RE30, respectively). High-amylose WP pet food exhibited lower damaged/gelatinized starch content compared with rice and RP pet foods. The total phenolic contents and the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging ability of the pet foods notably increased after the addition of RE, showing a clear upward trend as the incorporation level was elevated. RE10 (except for rice) and RE30 significantly decreased the starch digestibility of pet foods according to in vitro testing, with the greatest reduction observed for the high-amylose WP sample. Although RE1 did not significantly impact the overall in vitro and in vivo starch digestibility, the treatment consistently postponed the peak times of postprandial blood glucose responses to all the three extruded diets in beagles. The results indicated that RE effectively enhanced the antioxidant properties of extruded pet foods and slowed starch digestion rates. | |
