Type 2 diabetes, linked to an unhealthy diet, is increasing in Australia. This study aimed to evaluate the acceptability of potential antidiabetic food preventatives followed by phyto‐component detection by high‐performance liquid chromatography analysis and glycaemic index (GI) estimation by in vitro enzymatic hydrolysis. Five flakes and a cracker were developed from Acacia longifolia seeds, Typha orientalis rhizomes and Rhagodia candolleana berries. Samples were tested for consumer acceptability against a commercially available flake and cracker (as controls) by 44 participants using a 9‐point hedonic scale. Overall acceptability of 86.4% and 54.5%–65.9% was recorded against control and test flakes, while control and test crackers recorded 84.1% and 70.5%, respectively. The test cracker contained gallic acid (GA) and ρ‐coumaric acid (PCA) with GI, 47.7 ± 1.3, whereas control cracker contained GA and had GI, 70.3 ± 2.5. These results indicate that the test cracker may have potential as an antidiabetic food preventative.
