Effect of Asparagus falcatus and Taraxacum javanicum Inulins on Growth of L. acidophilus La-5 and B. animalis subsp lactis Bb-12, Cocultured in Skim Milk

Abstract

A study was conducted to evaluate the effect of inulin from Asparagus falcatus and Taraxacum javanicum on growth of Lactobacillus acidophilus (La-5) and Bifidobacterium animalis (Bb-12) in skim milk. Commercially available chicory inulin and chicory fructooligosaccharides (FOS) were used as positive controls. Skim milk (13% (w/v)) samples supplemented with different concentrations (0.5, 1, 2, 3 and 5%) of AF or TJ inulin, 5% Chicory inulin and 5% FOS, inoculated with mix culture of La-5 and Bb-12 (1:1), were incubated at 37 oC for 24 hours. The skim milk samples prepared the same way, but without adding inulin were used as negative controls. Optical density and pH of the milk samples were ch..
