A method for permanently coloring fruits (cherries) and vegetables using carmine and other anthraquinones, using mixtures of multivalent metal ions and acid. The cherries are infused with a mixture of calcium ions, other multivalent metal ions, and carmine dye, at a pH at which the carmine is in soluble form. The cherries are then infused with an acidification solution which results in the preciptation of an insoluble carmine-metal ion complex within the cherries. Unused dye is treated and recycled.

Method for coloring fruits and vegetables with anthraquinones and product

Apparatus for removing the peel from a pineapple comprises a cylindrical body provided with a toothed cutting edge designed to cut through a pineapple and fixed guide means telescopically positioned within the cylindrical body and adapted to direct the toothed cutting edge of the cylindrical body towards a pineapple that is placed on a cutting pad positioned in opposing relationship to the toothed cutting edge. The apparatus is optionally provided with a core tube slidably disposed in a passageway extending through the guide means and designed to cut through the central core of a pineapple placed on the cutting pad. The apparatus is also provided with means for simultaneously or separately moving the cylindrical body and the core tube towards the pineapple and the cutting pad.
