Abstract
Inadequate fibrous attributes and prohibitive pricing are pivotal barriers to the broader market penetration of meat analogs (MAs). This research endeavors to address these impediments by formulating a blend of cost-effective soybean meal (SM) and pea protein isolate (PPI) across a spectrum of ratios (PPI:SM = 1:0, 8:2, 6:4, 4:6, 2:8, and 0:1). The analysis of textural properties elucidated that the integration of SM markedly diminished the textural rigidity and mastication resistance of MAs. Employing scanning electron microscopy (SEM) and fibrillation degree metrics, it was ascertained that the most favorable fibrous architecture of MAs was attained at a PPI to SM ratio of 6:4. Further experimental evidence underscored that the synergistic interaction between SM and PPI catalyzed the conversion of free sulfhydryl groups into disulfide linkages, a pivotal mechanism in the augmentation of MAs' fibrous matrices. The conclusions drawn from this study provide substantive contributions to the formulation of superior-quality, economically viable MAs, and could potentially accelerate their market acceptance.
