The addition of L-Arg increased WHC, hardness, springiness,
cohesiveness, and chewiness of SSMP gel. Therefore, L-Arg showed
the potential benefit for the improvement of yield and texture of
SSMP gel. Additionally, the treatment with 0.20 g L-Arg/100 g
caused the increase in DH2, as well as the disappearance of Tmax1
and Tmax3. Meanwhile, SEM showed that L-Arg treatment resulted
in the formation of an even and compact gel. Such gel contributed
to the increased the fraction of T21 distribution. These results suggested
that the thermal stability and gelation of SSMP were affected
by L-Arg, which changed the microstructure of SSMP gel, and ultimately
improving the corresponding WHC and texture, as well as
changing the distribution of T21.
