Abstrakt: This study aimed to investigate the integration of cereal and germinated pseudocereals into set-type yogurt mimic, resulting in a novel and nutritious product. Four groups of yogurts mimic, namely CPY-1, CPY-2, CPY-3, and CPY-4, were prepared using different probiotic cultures, including L. acidophilus 21, L. plantarum 14, and L. rhamnosus 296 along with starter cultures. Notably, CPY-2 cultured with L. plantarum and L. rhamnosus and incubated for 12 h exhibited the most desirable attributes. The resulting yogurt demonstrated an acidity of 0.65%, pH of 4.37 and a probiotic count of 6.38 log CFU/mL. The logistic growth model fit revealed maximum growth rates (k, 1/h) and maximum bacterial counts (Nm log CFU/mL) for each CPY variant. The results revealed that CPY-2 significantly improved protein, dietary fiber, phenols and antioxidant capacities compared to the control. Scanning electron microscopy showed more structured and compact casein network in CPY-2, highlighting its superior textural characteristics. Overall, this study demonstrates the incorporation of cereal and germinated pseudocereals into set-type yogurt mimic offers health benefits through increased dietary fiber and β-glucan.
