Abstract
This study was carried out to investigate the antioxidant properties of synbiotic product, Lactobacillus acidophilus supplemented with 2.5% royal jelly in skim milk and Bifi dobacterium bifi dum supplemented with 7.5% royal jelly in skim milk, using DPPH (1,1-Diphenyl-2-picrylhydrazyl) radical scavenging assay, reducing power, total antioxidant in linoleic acid system and formation of diene-conjugation assay. Results showed that the synbiotic effect of royal jelly and probiotic bacteria provided substantial antioxidant activities. Milk samples fermented by B. bifi dum supplemented with 7.5% royal jelly and L. acidophilus supplemented with 2.5% royal jelly exhibited high scavenging activity with 96.8 and 93.3%, respectively, at a concentration of 500 μg/mL. IC50 values were estimated at 226.7 μg/mL for B. bifi dum supplemented with 7.5% royal jelly and at 210.2 μg/ml for L. acidophilus supplemented with 2.5% royal jelly. On the other hand, L. acidophilus supplemented with 2.5% royal jelly and B. bifi dum supplemented with 7.5% royal jelly exhibited signifi cantly high reducing power at a concentration of 1000 μg/mL. The percentages of peroxide inhibition of L. acidophilus supplemented with 2.5% royal jelly and B. bifi dum with 7.5% royal jelly were 52% and 42%, respectively. Signifi cant inhibitions were found in the formation of conjugated diene at 66.9% and 65.8% for L. acidophilus with 2.5% royal jelly and B. bifi dum with 7.5% royal jelly, respectively. These results were compared with standards BHT, ascorbic acid and Trolox. Original article Section: Food Chemistry
