Abstract
A spectral-optical investigation of the color of the red plum peel found in different aggregate states has been performed with the aim of its standardization in accordance with the demands of the food industry. The absorption spectra as well as the rotary dispersion and linear dichroism spectra of this food color have been obtained. The latter made it possible to reveal bands of individual pigments of the above-indicated color, “latent” in its absorption spectrum, and determine the positions of their maxima.
