Pectin and cellulose were coprecipitated from a binary dispersion in dimethyl sulfoxide. The coprecipitate was differentially stained and viewed under a microscope. Mounts that were prepared by evaporating samples of the coprecipitate as a film on microscopic slides contained uniformly distributed pectin and cellulose throughout the matrix. Mounts of dried, milled coprecipitate showed concentrations of cellulose primarily on the outer surface of pectin globules. This location of cellulose in the coprecipitate might be a consequence of milling which ruptured the possibly more fragile cellulose‐cellulose bonds, vis‐a‐vis pectin‐cellulose or pectin‐pectin bonds of the inter‐micellar aggregates.
