In this study, the high-moisture meat analogs (HmMAs) were developed by incorporating defatted sesame cake powder (DSP) in soy protein isolate (SyPI). The quality attributes of HmMA like visual appearance, specific mechanical energy (SME), mass flow rate (MFR), phenolic profile, textural and rheological properties were assessed after varying DSP concentrations (0%, 20%, 40%, and 60% w/w) and feed moisture (FM) levels (55% and 60%). The HmMA (derived solely from SyPI) exhibited higher hardness, chewiness, gumminess, cohesiveness, and springiness. The HmMA prepared from SyPI-DSP blends (HmMA) demonstrated significant improvements in nutritional composition, and their visual characteristics indicated noticeable anisotropy. The interaction between SyPI and DSP influenced the quality of HmMA. The higher DSP concentration led to higher MFR and deeper curvatures of U-shaped structures, whereas lower SMS, textural and rheological properties. The DSP incorporation and 55% FM adjustments allowed mimicking meat cuts with thick fiber, influenced color, and proved advantageous in developing white meat analogs with higher free phenolics. The findings of the study suggest avenues for exploring DSP at a suitable level in SyPI for the development of better quality meat analogs.
在本研究中,通过将脱脂芝麻饼粉(DSP)掺入大豆分离蛋白(SyPI)中来制备高水分肉类模拟物(HmMAs)。在改变DSP浓度(0%、20%、40%和60% w/w)和进料水分(FM)水平(55%和60%)后,评估了HmMA的质量属性,如外观、比机械能(SME)、质量流率(MFR)、酚类成分、质地和流变学特性。仅由SyPI制成的HmMA表现出更高的硬度、咀嚼性、胶黏性、内聚性和弹性。由SyPI-DSP混合物制备的HmMA在营养成分方面有显著改善,其视觉特征显示出明显的各向异性。SyPI和DSP之间的相互作用影响了HmMA的质量。较高的DSP浓度导致较高的MFR和U形结构的更深曲率,而较低的比机械能、质地和流变学特性。掺入DSP和调整至55%的FM能够模拟出具有粗纤维的肉块,影响颜色,并证明有利于开发具有更高游离酚类的白肉模拟物。该研究结果为在SyPI中以合适水平探索DSP以开发更高质量的肉类模拟物提供了途径。
