Abstract
Overview
ISO 735:1977 specifies a laboratory method for the in oilseed residues. The procedure applies to residues produced by extraction of oil from oilseeds (pressure or solvent extraction), excluding compounded products. The method treats the total ash (see ) with hydrochloric acid to dissolve acid‑soluble material, then incinerates and weighs the remaining insoluble residue.
