This study aimed to utilize transglutaminase and gallic acid as stabilizers and thickeners in ice cream production. Additionally, it explored the potential for enhancing the physicochemical properties of ice cream mixtures by partially replacing the stabilizer with transglutaminase (0.36g/100gprotein) (IC2), gallic acid (2.5g) (IC3), and a combination of transglutaminase (0.22g/100gprotein) and gallic (1.5g) acid (IC4). These mixtures were compared with a control mixture containing only the stabilizer (IC1). The properties of the prepared ice cream, including titratable acidity, pH, melting time, morphology, thermal stability, and sensory attributes, were studied. The results revealed that IC4 exhibited superior properties compared to the control mixture and other prepared mixtures across all evaluated aspects. Specifically, the study observed a decrease in pH alongside an increase in titratable acidity after aging, and IC4 demonstrated the highest melting time, stability, and overall acceptance. Furthermore, sensory evaluation results showed that the IC4 blend received the highest sensory rating at 91%. Overall, these findings highlight the potential for optimizing ice cream formulations through strategic use of additives, paving the way for advancements in ice cream production and product quality.
