Full title and description

Animal and vegetable fats and oils — Determination of visible foots in crude fats and oils. This International Standard specifies a laboratory method to determine visible matter (sediments/foots) in crude fats and oils that can be separated by gravity, for use in quality control and acceptance testing of crude lipid materials.

Abstract

ISO 19219:2002 defines a straightforward gravimetric procedure to quantify visible solid material or sediments in crude animal and vegetable fats and oils. The method covers sampling considerations for the test portion, separation by gravity, and reporting of results intended for routine quality assessment of crude fats and oils.

General information

• Status: Published (confirmed international standard).
• Publication date: April 2002 (ISO publication, 1st edition).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 67.200.10 — Fats and oils; technical committee ISO/TC 34/SC 11.
• Edition / version: Edition 1 (2002).
• Number of pages: 7 (main ISO document; national/EN adoptions may include additional front matter).

Scope

This standard specifies a method for the determination, in crude fats or oils, of visible matter which can be separated by gravity. It is intended for samples of crude (unrefined) animal and vegetable fats and oils and is applicable where a simple assessment of visible sediments or solid inclusions is required for acceptance, storage or processing decisions. It does not cover refined oils or microscopic or dissolved contaminants.

Key topics and requirements

• Definition of the measurable “visible foots”/sediments that are separable by gravity.
• Procedure for preparing a representative test portion from crude fats and oils.
• Gravity separation technique and settling/decantation steps required to isolate visible sediments.
• Reporting format and expression of results (typically mass or percentage of visible material relative to sample mass).
• Limitations of applicability — designed for crude products rather than refined oils or particulate quantification by other analytical means.

Typical use and users

Used by oilseed processors, rendering plants, edible oil refineries, trading companies, incoming goods inspection and independent testing laboratories for routine quality control and acceptance testing of crude fats and oils. Also referenced by purchasers and regulatory/standards bodies when visible sediment content is part of product specifications.

Related standards

ISO 19219 is part of the body of ISO/TC 34/SC 11 standards covering methods for animal and vegetable fats and oils. Other related methods address physicochemical determinations (acid value, moisture and volatile matter, impurities) and sampling standards for fats and oils; national and EN adoptions (for example EN/ISO versions) exist that are technically identical but include national front matter.

FAQ

Q: What is this standard?

A: ISO 19219:2002 is an international standard that specifies a method to determine visible matter (sediments or “foots”) in crude animal and vegetable fats and oils by gravity separation.

Q: What does it cover?

A: It covers the scope, test procedure and reporting for quantifying visible, gravity-separable material in crude fats and oils. It is not intended for refined oils or for microscopic or dissolved contaminants.

Q: Who typically uses it?

A: Producers, refiners, renderers, quality control and inspection laboratories, buyers and standards/regulatory bodies involved in assessing crude fats and oils for storage, processing or trade.

Q: Is it current or superseded?

A: The ISO record shows ISO 19219:2002 as published and subsequently confirmed in review cycles (i.e., the document has been maintained as a confirmed international standard). For the current confirmation status and any national adoptions, consult the ISO catalogue or national standards body.

Q: Is it part of a series?

A: ISO 19219 is one of several standards produced under ISO/TC 34/SC 11 dealing with analytical methods and specifications for animal and vegetable fats and oils; related ISO and EN/ISO documents cover other test methods and sampling procedures.
