Actin, a multifunctional protein highly expressed in
eukaryotes,
is widely distributed throughout cells and serves as a crucial component
of the cytoskeleton. Its presence is integral to maintaining cell
morphology and participating in various biological processes. As an
irreplaceable component of myofibrillar proteins, actin, including
G-actin and F-actin, is highly related to food quality. Up to now,
purification of actin at a moderate level remains to be overcome.
In this paper, we have reviewed the structures and functions of actin,
the methods to obtain actin, and the relationships between actin and
food texture, color, and flavor. Moreover, actin finds applications
in diverse fields such as food safety, bioengineering, and nanomaterials.
Developing an actin preparation method at the industrial level will
help promote its further applications in food science, nutrition,
and safety.
