Induction of Red Color Formation in Cabbage Juice by Lactobacillus brevis and Its Relationship to Pink Sauerkraut1

RESUMO

Membrane-filtered cabbage juice, when fermented by Lactobacillus brevis under conditions of controlled pH, frequently produced a water-soluble red pigment. The pigment, presumably responsible for imparting a highly objectionable discoloration to sauerkraut, was formed during the post logarithmic phase of growth. Color development is pH dependent (5.2 to 6.3) and can be suppressed by chemical reductants or anaerobic conditions of growth. The compound responsible for discoloration was purified and partially characterized.
