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 6571 was prepared by Technical Committee ISO/TC 34, Food products, Subcommittee SC 7, Spices,
culinary herbs and condiments.
This second edition cancels and replaces the first edition (ISO 6571:1984) of which it constitutes a technical
revision.

INTERNATIONAL STANDARD ISO 6571:2008(E)
Spices, condiments and herbs — Determination of volatile oil
content (hydrodistillation method)
1 Scope
This International Standard specifies a method for the determination of the volatile oil content of spices,
condiments and herbs.
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 939, Spices and condiments — Determination of moisture content — Entrainment method
ISO 2825, Spices and condiments — Preparation of a ground sample for analysis
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
volatile oil content
all the substances entrained by steam under the conditions specified in this International Standard
NOTE The volatile oil content is expressed in millilitres per 100 g of dry product.
4 Principle
An aqueous suspension of the product is distilled. The distillate is collected in a graduated tube containing a
measured volume of xylene to fix the volatile oil. The organic and aqueous phases are then allowed to
separate and the total volume of the organic phase read. The volatile oil content is calculated after deducting
the volume of xylene.
5 Reagents
Use only reagents of recognized analytical grade and only distilled water or water of at least equivalent purity.
5.1 Xylene.
5.2 Cleaning solutions.
5.2.1 Acetone (for fatty residues).
