Full title and description
ISO 22855:2008 — Fruit and vegetable products — Determination of benzoic acid and sorbic acid concentrations — High‑performance liquid chromatography (HPLC) method. This International Standard specifies an HPLC-based analytical procedure for the determination of benzoic and sorbic acids in fruit and vegetable juices.
Abstract
ISO 22855:2008 describes a validated high‑performance liquid chromatography method (including sample preparation, chromatographic conditions and calibration) for measuring the concentrations of benzoic acid and sorbic acid in fruit and vegetable juices. The standard is intended to provide laboratories with a reproducible procedure for preservative analysis in these matrices.

Scope
ISO 22855:2008 is applicable to the determination of benzoic and sorbic acid concentrations in fruit and vegetable juices using an HPLC technique. The standard covers required reagents, sampling and sample preparation, chromatographic conditions, calibration and calculation procedures and performance/validation criteria for routine and regulatory testing of these preservatives in the specified matrices. It is not intended to replace methods developed for other food matrices (for example, milk products are covered by a separate ISO method).
Key topics and requirements
- Principle: reversed‑phase high‑performance liquid chromatography with appropriate detection for benzoic and sorbic acids.
- Required reagents and reference standards for preparation of calibration solutions.
- Sample preparation and extraction procedures tailored to fruit and vegetable juice matrices.
- Recommended chromatographic conditions (column type, mobile phase composition, flow rate and detection wavelength) and system suitability checks.
- Calibration, calculation of concentrations and reporting conventions.
- Performance and validation criteria (precision, accuracy, limit of detection/quantification, and quality control measures) appropriate for routine laboratory use.
These topics are defined to ensure reproducible, comparable results between laboratories following the method.
Typical use and users
Primary users are analytical and quality‑control laboratories in the food and beverage industry, regulatory and public health laboratories, third‑party testing laboratories, and standards bodies performing routine testing of fruit and vegetable juices for preservative compliance and food‑safety monitoring. National standards bodies and accredited testing labs commonly adopt this ISO method for formal compliance testing.
Related standards
Other ISO methods address benzoic and sorbic acid determination in different food matrices — for example ISO 9231:2008 covers milk and milk products. Additional ISO and regional standards (and relevant national methods) on fruit and vegetable product testing (pH, titratable acidity, soluble solids, multiresidue pesticide methods) are commonly used alongside ISO 22855:2008 in food testing laboratories.

FAQ
Q: What is this standard?
A: ISO 22855:2008 is an International Standard that specifies an HPLC method for the determination of benzoic and sorbic acid concentrations in fruit and vegetable juices.
Q: What does it cover?
A: It covers the analytical principle, reagents, sample preparation, recommended chromatographic conditions, calibration and calculation procedures, system suitability and performance/validation criteria needed to measure benzoic and sorbic acids accurately in fruit and vegetable juice matrices.
Q: Who typically uses it?
A: Food and beverage industry QC laboratories, regulatory testing labs, third‑party contract testing laboratories, and national standards organizations use this method for routine preservative testing and compliance verification.
Q: Is it current or superseded?
A: As of its latest ISO lifecycle review, ISO 22855:2008 remains a published International Standard; it was confirmed in ISO’s systematic review process (confirmation recorded in 2023), so the 2008 edition is current. Users should verify national adoptions or more recent replacements before formal regulatory use. (Published 15 January 2008; corrected/reprinted 15 April 2008; confirmation recorded 30 March 2023).
Q: Is it part of a series?
A: ISO 22855:2008 is a single‑matrix method for fruit and vegetable juices. Related ISO methods exist for other matrices (for example ISO 9231:2008 for milk and milk products) and a number of companion standards cover other analytical determinations for fruit and vegetable products.
Q: What are the key keywords?
A: Benzoic acid; sorbic acid; preservative analysis; HPLC; fruit and vegetable juices; food analysis; ISO 22855:2008.
