Understanding Key Standards for Animal and Vegetable Fats and Oils: Analysis and Quality Control

Animal and vegetable fats and oils play a crucial role across the food industry, cosmetics, pharmaceuticals, and beyond. As global trade intensifies and consumers demand ever-higher levels of quality and safety, adhering to international standards has become critical for any business working with oils and fats. This article explores two of the most important standards in this sector, providing clear guidance on their requirements, core concepts, and practical benefits for businesses and consumers alike.

Overview / Introduction

In the rapidly evolving world of food technology, animal and vegetable fats and oils represent not just essential nutritional components but also critical industrial ingredients. As food producers, refiners, distributors, and regulators grapple with increasing globalization and complex supply chains, ensuring product purity, identity, and safety has never been more important. Here, international standards step in as the backbone of quality management and compliance.

Whether you are a food technologist, quality manager, olive oil producer, or a member of the general public with an interest in food safety, understanding these standards equips you to make informed decisions, improve operational productivity, and protect consumer trust. In this article, we’ll examine:

• CEN ISO/TS 22115:2021: A breakthrough method for analyzing lipid classes by capillary gas chromatography.
• EN ISO 12872:2022: A precise technique for quantifying 2-glyceryl monopalmitate in olive and olive-pomace oils.

You will discover not only what these standards cover but also why implementing them is now essential for modern businesses striving for safety, traceability, compliance, and competitive advantage.

Detailed Standards Coverage

CEN ISO/TS 22115:2021 - Lipid Class Profiling by Capillary Gas Chromatography

Animal and vegetable fats and oils - Separation of lipid classes by capillary gas chromatography (fingerprint method) (ISO/TS 22115:2021)

What This Standard Covers

The CEN ISO/TS 22115:2021 standard specifies a semi-quantitative method for separating and screening lipid classes in a variety of animal and vegetable oils, fats, and related samples (including oil/fat deodistillates). At the core of the method is capillary gas chromatography (GC), a sophisticated analytical technique known for its precision and speed.

Designed primarily for obtaining detailed profiles of both main components (such as triglycerides) and minor but critical compounds (including sterols, sterol esters, tocopherols, wax esters, fatty alcohols, and glycerol), this standard transforms how laboratories conduct rapid assessments of oil and fat samples. The "fingerprint" method delivers a powerful tool for:

• Qualitative and semi-quantitative analysis
• Comparing different oil and fat samples for authenticity and composition
• Streamlining quality control and detecting potential adulteration

Key Requirements and Specifications

The standard involves chemically modifying (silylating) hydroxylated compounds to prepare them for accurate detection via GC. It sets out precise requirements for reagents, apparatus, preparation of internal standards, and calibration protocols. Compounds analyzed include those commonly present in edible oils and fats, each detected as a specific chromatographic peak. While the method is ideal for screening and relative comparison, dedicated quantitative methods remain preferable for strict measurement of pre-identified compound classes.

Core procedural highlights include:

• Preparation of samples and calibration using a range of reference compounds
• Silylation to stabilize sensitive components
• Use of a high-temperature capillary GC equipped with flame ionization detection (FID)
• Inclusion of internal and external standards for calibration and quantitation
• Rigorous test reporting and optional interlaboratory validation

Who Needs to Comply?

This standard is vital for:

• Food and oil quality control laboratories
• Producers and refiners of edible and technical animal/vegetable oils
• Regulatory authorities overseeing oil and fat safety
• Researchers focused on lipid analysis

Compliance ensures that compositional screening is accurate, repeatable, and compatible with international trade requirements.

Practical Implications for Implementation

Adopting CEN ISO/TS 22115:2021 allows businesses to:

• Implement robust and harmonized quality control systems
• Rapidly screen raw materials and finished products for conformity and purity
• Detect adulteration or contamination early, minimizing economic and reputational losses
• Accelerate productivity and throughput in laboratory operations

Key highlights:

• Efficient fingerprinting of main and minor lipid classes in a single run
• Improved authenticity and adulteration detection
• Harmonized methodology for international trade and compliance

EN ISO 12872:2022 - 2-Glyceryl Monopalmitate in Olive Oils

Olive oils and olive-pomace oils - Determination of the 2-glyceryl monopalmitate content (ISO 12872:2022)

What This Standard Covers

EN ISO 12872:2022 establishes an authoritative procedure for determining the mass fraction (as percentage) of 2-glyceryl monopalmitate in both olive oils and olive-pomace oils—products that are liquid at standard ambient temperature (20°C). This monoglyceride is a significant indicator for assessing quality, authenticity, and correct processing of olive oils.

Rooted in the internationally endorsed methods of the International Olive Council (IOC), this standard enables:

• Reliable differentiation between extra virgin, lampante, and pomace olive oils
• Quality assurance and fraud prevention
• Conformance to export/import requirements for olive oil markets

Key Requirements and Specifications

The analytical technique is based on enzymatic hydrolysis (using pancreatic lipase), followed by silylation and capillary gas chromatography of the resulting monoacylglycerol fraction. The method lays out:

• Step-by-step sample treatment: including silica gel chromatography and hydrolysis
• Production of silylated derivatives for gas chromatographic analysis
• Identification and quantification of 2-glyceryl monopalmitate
• Provisions for the use of either hexane or iso-octane as chromatographic solvents
• Strict calibration, control, and documentation practices

This updated edition adds clarity and enhanced reproducibility to the analytical protocol, supporting the enforcement of international trade standards and food labeling laws.

Who Needs to Comply?

• Olive oil and pomace oil producers and exporters
• Accredited food testing laboratories
• Food safety authorities and trade inspection bodies
• Retailers and importers sourcing from diverse suppliers

Meeting this standard is essential for market access, fraud protection, and consumer trust in premium olive oil products.

Practical Implications for Implementation

Implementing EN ISO 12872:2022 means:

• Achieving objective, reproducible measurement of monopalmitate content for certification and branding
• Supporting product claims such as "extra virgin" or "refined"
• Minimizing the risk of legal disputes or recalls in international olive oil markets
• Increasing the efficiency and transparency of quality assurance throughout the supply chain

Key highlights:

• Accurate measurement of a critical quality marker in olive oils
• Enhanced detection of fraud and adulteration
• Alignment with IOC, ISO, and CEN food labeling and export requirements
