Method for obtaining useful materials from the by-products of fruit and vegetable processing

摘要

A method for obtaining useful materials from the by-products of fruit and vegetable processing. In order to obtain pectin as a first useful substance from the by-products with the aid of a selective adsorber, the polyphenols contained in the by-products are separated as a second useful substance and are obtained as a result of subsequent desorption of the adsorber. By-products which are especially used here are those arising during the production of juice from ripe fruits or vegetables, i.e. apple marc or citrus marc in particular.
