Full title and description

ISO 9622:2013 — Milk and liquid milk products — Guidelines for the application of mid‑infrared spectrometry. This International Standard provides guidance for quantitative compositional analysis of milk and derived liquid products using mid‑infrared absorption measurements (ISO/IDF joint designation IDF 141).

Abstract

ISO 9622:2013 gives guidelines for the quantitative determination of compositional parameters (for example fat, protein, lactose and other constituents) in raw milk, processed milk, cream and whey by measurement of the absorption of mid‑infrared radiation. It describes instrument features, calibration considerations and control procedures; guidance is written primarily for cow’s milk but can be applied to other species provided appropriate calibrations are generated.

General information

• Publication date: September 2013 (Edition 2).
• Publisher: International Organization for Standardization (ISO) — published jointly as ISO/IDF 141.
• ICS / categories: 67.100.10 (dairy industry — milk and milk products).
• Edition / version: Edition 2 (2013).
• Number of pages: 14 pages (ISO web catalogue).

Scope

The standard provides guidelines for applying mid‑infrared (MIR) spectrometry to the compositional analysis of milk and liquid milk products. It covers recommended instrument features (including additional built‑in sensors such as conductivity), calibration generation and validation, measurement control procedures and the applicability to milk from different species when appropriate calibrations are developed. It does not replace specific legally mandated test methods but supports routine laboratory and in‑line analysis practices.

Key topics and requirements

• Principles of mid‑infrared absorption measurement for milk composition determination.
• Instrumentation features and recommended built‑in sensors (for example conductivity) that can improve measurement performance.
• Guidance on generating, validating and maintaining calibration models for different milk types and derived products.
• Quality control and routine operational procedures to ensure reliable compositional results.
• Notes on applicability to non‑bovine milks (goat, sheep, buffalo) provided adequate calibration and control procedures are in place.

Typical use and users

Used by dairy testing laboratories, milk processing companies, on‑farm testing services, instrument manufacturers, research institutions and regulatory or accreditation bodies involved in routine compositional analysis of milk and liquid dairy products. It is intended for users implementing MIR‑based analysis or developing/maintaining calibrations and quality control systems.

Related standards

ISO 9622:2013 replaces ISO 9622:1999 (withdrawn) and is published with the joint IDF designation IDF 141. Users should also consider other ISO/IDF standards covering sampling, reference methods and specific dairy testing protocols when establishing laboratory systems.
