Seventy-two offspring pigs (150 d) from 27 sow (9 sows per group) fed different vitamin D 3 levels were used to evaluate the effects of maternal vitamin D 3 status and postmortem cold storage on cooking loss, color, texture profile analysis (TPA), lowfield nuclear magnetic resonance (LF-NMR) T 2 relaxation times and dynamic rheological of gel properties of chilled pork batters in offspring pigs. Sows were allotted to low, normal, and high dietary vitamin D 3 groups which contained 200 (LD), 800 (ND), and 3200 (HD) IU of vitamin D 3 /kg basal diet, respectively. Results showed that HD group had higher a* value, hardness, cohesiveness, springiness, chewiness, and storage modulus (G') values, while had lower cooking loss, L* value, T 21 and T 22 relaxation time compared with LD group during postmortem cold storage period (P < 0.05). In addition, cold storage time increased cooking loss and b* values of LD and ND groups, TPA parameters, T 22 relaxation time and G' values of all experimental groups, while decreased a* and L* values of LD and ND groups (P < 0.05). The results revealed that maternal high-dose vitamin D 3 levels influenced these indicators of chilled pork batters in offspring pigs, which improved the quality attributes during postmortem cold storage.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
