Abstract

This study utilized Antarctic krill (AK) meat as the primary substrate to construct a hybrid protein system by adjusting the proportions of wheat gluten (WG) and pea protein (PP). Further, it investigated the effects of different components on the hybrid protein extrudates (HPE). Results demonstrate that an optimal proportion (W20P5) yields the highest fibrous degree, accompanied by a peak in disulfide bond content. Besides, WG forms a stable three-dimensional framework during extrusion, closely binding different components. Increasing the PP content initially decreases and later increases the density and thermal stability of the HPE. Thus, low PP possibly interferes with the cross-linking between WG and AK myofibrillar proteins, while excessive PP leads to structural disorder and crystal size fluctuations. In summary, this study reveals the effects of WG and PP on the AK meat-based hybrid protein systems in high-moisture extrusion, offering new insights into the construction of hybrid protein systems.
