ABSTRACT:
The present invention provides a coloring agent and process for preparing yeast cell ghosts having a light color and less flavor. The yeast cell ghosts are to be contained as a component of the coloring agent. Further, the yeast cell ghosts contain a proportion of intact yeast cell walls and one color source. The color source is selected based upon the desired color in the coloring agent and in any product in which the coloring agent is used, such as a pigment or dye. Also uses for the coloring agent are disclosed, such as their use in foodstuffs, pharmaceuticals and cosmetics. The coloring agents must be acceptable for food and pharmaceutical use. The steps for making the yeast cell ghosts are sequential and involve extracting yeast debris having a solids content not exceeding 20% by weight. An acid is used to perform the extraction and further treatment of the extracted debris with an alkali to obtain whole cells and cells having disrupted cell walls. The whole cells are separated away from the material rich in disrupted cell walls and the material is then bleached to provide for the yeast cell ghosts.
