Description

The red pigment from the roots of table beet (Beta vulgaris L.) is commercially used as a food colorant. We established the efficient cell culture system of table beet. The properties and application of the red pigment obtained from the cultured cells as a food colorant were investigated. When the cells of table beet was cultured in the revised Linsmaier-Skoog medium in a 30l jar fermentor under a dark condition for 13 days, the cell yield was 25g dry wt./l and betacyanin content was 0.92%. Heat and light stability of the red pigment from cultured cells were similar to those of the pigment from table beet roots. Fish and pork meat sausages colored with the pigment from cultured cells revealed the similar properties of coloring to those with the pigment from the roots. This study suggested that the red pigment from cultured cells can be used as a food colorant, and this cell culture system of table beet can be available for the stable pigment production on a practical level.
