Foreword
ISO (the International Organization for Standardization) is a worldwide
federation of national standards bodies (ISO member bodies). The work of
preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which
a technical committee has been established has the right to be represented
on that committee. International organizations, governmental and non-
governmental, in liaison with ISO, also take part in the work. ISO
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard ISO 734-1 was prepared by Technical Committee
ISO/TC 34, Agricultural food products, Subcommittee SC 2, Oleaginous
seeds and fruits.
This first edition of ISO 734-2, together with ISO 734-1, cancels and
replaces ISO 734:1979, which has been technically revised.
ISO 734 consists of the following parts, under the general title Oilseed
residues — Determination of oil content:
 Part 1: Extraction method with hexane (or light petroleum)
 Part 2: Rapid extraction method
Annexes A and B of this part of ISO 734 are for information only.

INTERNATIONAL STANDARD  ISO ISO 734-2:1998(E)
Oilseed residues — Determination of oil content —
Part 2:
Rapid extraction method
1  Scope
This part of ISO 734 specifies an extraction method which may be used to assess the efficiency of a de-oiling
process by comparing the oil content of the oilseed with the residual oil content of the corresponding extraction
meals, pellets and expeller cakes.
It is applicable to oilseed residues obtained from oilseeds by expelling or by extraction with a solvent, as well as to
the pellets made from the residues.
2  Normative references
The following standards contain provisions which, through reference in this text, constitute provisions of this part of
ISO 734. At the time of the publication, the editions indicated were valid. All standards are subject to revision, and
parties to agreements based on this part of ISO 734 are encouraged to investigate the possibility of applying the
most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid
International Standards.
