Abstract:
:This study was conducted to investigate the effects of Lactobacillus plantarum NJAU-01 isolated from Chinese dry-cured ham (Jinhua ham) on the regulation of protein oxidation of fermented sausages. Fermented sausages were prepared with different concentrations of L. plantarum NJAU-01 (105 CFU/g, 107 CFU/g and 109 CFU/g), and the commercial strain was used as positive control. The results showed that L. plantarum NJAU-01 at 107 CFU/g and 109 CFU/g significantly lowered the protein carbonyl content and protein surface hydrophobicity compared with the control (P < 0.05). The total sulfhydryl contents in L. plantarum NJAU-01 groups were significantly higher than that of the group without starter culture (P < 0.05). Significant changes were found in sarcoplasmic protein bands within 130-250 kDa, 100-130 kDa and 25-35 kDa during sausage fermentation (P < 0.05). Our data suggest that L. plantarum NJAU-01 has the potential to be an antioxidant starter culture in fermented sausages.
