Physicochemical and Sensory Properties of Bahulu and Chocolate Mousse Developed from Canned Pulse and Vegetable Liquids

Abstract

Egg white is the most commonly used foaming agent in various aerated foods. Malaysia has been experiencing an egg crisis due to lower production and increased egg consumption rates since the COVID-19 restrictions were lifted. Thus, finding an alternative functional ingredient to address the egg shortage is essential. Liquids discarded from commercially plant-based canned foods have the potential to replace eggs in food products as an alternative foaming agent. Therefore, this study aims to investigate the physicochemical and sensory properties of bahulu and chocolate mousse using canned liquids of green peas (pulses N and P), lentils (pulse R), chickpeas (pulse X), button mushrooms (vegetable A), and straw mushrooms (Vegetable D). Canned liquids were incorporated into bahulu and mousse formulations to replace egg whites. The developed bahulu and mousse were baked for 25 min at 180 °C and chilled for 3 hours at 4 °C, respectively. The texture profile of bahulu and the viscosity properties of the chocolate mousse were determined in this study. Furthermore, the research examines the proximate analysis and sensory acceptance of both products. According to the findings, bahulu A, produced from canned vegetable liquids, had the lowest hardness, springiness, and chewiness (p < 0.05) levels. In contrast, canned pulse liquid, which was used in bahulu N, produced comparable hardness, fracturability, adhesiveness, springiness, cohesiveness, and chewiness with the control sample (p > 0.05). Moreover, the viscosity values of mousses A (2238.33 ± 2.89 cP) and D (2778.33 ± 2.89 cP) were lower than the control mousse (8005.00 ± 0.00 cP) (p < 0.05). Bahulu and mousse contain 6.58–6.83% and 1.52–1.90% of protein, respectively. The protein content of canned pulse liquid products was higher than that of canned vegetable liquids (p < 0.05). The lowest taste acceptance was observed in samples Bahulu N and P as well as mousses N and P (p < 0.05). This outcome could be due to the saltiness derived from the canned green pea liquid. The appearance, odor, and overall acceptability of the bahulu and mousse were comparable to the control samples and well-accepted by the panelists (p > 0.05). The findings demonstrate that canned pulse liquids (green peas, lentils, and chickpeas) can potentially mimic egg white in the development of bahulu and chocolate mousse.
