Oilseed meals - Determination of oil content - Part 2: Rapid extraction method (ISO 734-2:2008)

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 not applicable to disputed cases, for which ISO 734-1 is applicable. It is applicable to oilseed meals obtained from oilseeds by expelling or by extraction with a solvent, as well as to the pellets made from the residues.

Ölsamenschrote - Bestimmung des Ölgehaltes - Teil 2: Schnellextraktionsverfahren (ISO 734-2:2008)

Dieser Teil von ISO 734 legt ein Extraktionsverfahren fest, das zur Beurteilung der Wirksamkeit von Ölgewinnungsverfahren durch Vergleich des Ölgehaltes der Ölsamen mit dem Restölgehalt in den jeweiligen Extraktionsschroten, Pellets und Ölkuchen verwendet werden darf.
Das Verfahren ist nicht anwendbar auf strittige Fälle, für die ISO 734-1 anwendbar ist.
Das Verfahren ist anwendbar auf Ölsamenschrote, die durch Pressen oder durch Extraktion mit einem Lösungsmittel aus Ölsamen gewonnen wurden, sowie auf die aus den Rückständen hergestellten Pellets.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. 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.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 734-2 was prepared by Technical Committee ISO/TC 34, Food products, Subcommittee SC 2,
Oleaginous seeds and fruits and oilseed meals.
This second edition cancels and replaces the first edition (ISO 734-2:1998), which has been technically
revised.
ISO 734 consists of the following parts, under the general title Oilseed meals — Determination of oil content:
⎯ Part 1: Extraction method with hexane (or light petroleum)
⎯ Part 2: Rapid extraction method

Oilseed meals — 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 not applicable to disputed cases, for which ISO 734-1 is applicable.
It is applicable to oilseed meals 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 referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
ISO 771, Oilseed residues — Determination of moisture and volatile matter content
ISO 5502, Oilseed residues — Preparation of test samples
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
oil content
sum of the mass fractions of the substances extracted under the operating conditions specified in this part of
ISO 734 on the basis of the product as received
NOTE 1 The mass fraction is expressed as a percentage.
NOTE 2 On request, the oil content may be expressed relative to dry matter.
4 Principle
The test portion is ground in a micro-ball mill in the presence of a solvent and subsequently extracted with the
same solvent in a suitable apparatus. The solvent is removed from the extract by distillation, then the residue
is weighed after drying.
