Oilseed meals - Determination of oil content - Rapid extraction method (ISO 22630:2015)

ISO 22630:2015 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 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.

ISO 22630:2015 spécifie une méthode par extraction permettant d'estimer le niveau d'efficacité du processus de délipidation par comparaison entre la teneur en huile d'un tourteau de graines oléagineuses et la teneur en huile résiduelle des farines, granulés et tourteaux en plaque correspondants.
Elle ne s'applique pas en cas de litige, auquel cas, c'est l'ISO 734 qui s'applique.
ISO 22630:2015 s'applique aux tourteaux de graines oléagineuses obtenus par pression ou par extraction des graines oléagineuses à l'aide d'un solvant, ainsi qu'aux granulés élaborés à partir de ces tourteaux.

Obroki iz oljnic - Določevanje olja - Metoda hitre ekstrakcije (ISO 22630:2015)

Ta mednarodni standard določa metodo ekstrakcije, ki se jo lahko uporabi za oceno učinkovitosti postopka razoljenja s primerjavo olja v oljnicah in ostankov olja v ustreznih mokah, peletah in pogačah, pri katerih je bila izvedena ekstrakcija.
Ne velja za sporne primere, za katere velja standard ISO 734. Velja za moko iz oljnih semen, pridobljeno iz oljnic z izločanjem ali ekstrakcijo s topilom, ter tudi za pelete, izdelane iz ostankov.

Overview

EN ISO 22630:2015 - Oilseed meals - Determination of oil content - Rapid extraction method (ISO 22630:2015) is a CEN-endorsed method for quickly assessing the oil content of oilseed meals, pellets and expeller cakes. The standard is intended to evaluate the efficiency of de‑oiling processes by comparing the oil content of the original oilseed with the residual oil in by‑products. It is not intended for legal dispute cases (see ISO 734).

Key topics and technical requirements

• Principle: Wet milling the test portion in a micro‑ball mill with solvent, followed by solvent extraction, distillation of solvent and weighing the dried residue to determine oil content.
• Test portion: Typical sample mass is 5 g of well‑mixed test sample placed in an extraction thimble.
• Grinding and extraction:
  • Wet grinding in a mechanical microgrinder (micro‑ball mill) with about 20 ml solvent for ~10 min (alternative: horizontal shaker 45 min at specified settings).
  • Rinse and transfer to a continuous extraction apparatus (100–200 ml flask, extractor, reflux condenser).
  • Cover the thimble with cotton wool and carry out reflux extraction; solvent is removed from the extract by distillation and residue dried and weighed.
• Solvents: Technical hexane, n‑hexane or light petroleum ether (specified boiling range and residue limits - residue on complete evaporation ≤ 2 mg/100 ml). Solvent recovered by distillation should not be reused for determinations.
• Apparatus & conditions: Analytical balance (0.001 g), drying oven at 103 °C ± 2 °C, extraction thimbles (25 × 100 mm) and appropriate microgrinder and extraction apparatus. Cooling required for PTFE grinding beakers.
• Results & quality: Method includes instructions for expression of results, repeatability/reproducibility assessment and interlaboratory precision checks.

Applications and users

• Quality control laboratories in the oilseed processing and animal feed industries for rapid monitoring of residual oil in meals, pellets and expeller cakes.
• Processing plants assessing de‑oiling efficiency of expellers or solvent extraction lines.
• Research and development teams optimizing extraction processes or product formulations.
• Contract and commercial testing labs performing routine compositional analysis.

Related standards

• ISO 734 - Reference method for disputed cases (not replaced by EN ISO 22630 for dispute testing).
• ISO 771 - Determination of moisture and volatile matter content (relevant for dry‑matter corrections).
• ISO 5502 - Preparation of test samples (sample preparation requirements referenced).
• Note: EN ISO 22630:2015 supersedes EN ISO 734‑2:2010.

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.
