Application Note: Fast and accurate method to determine saponification number
2 April 2024

The saponification number evaluates the quality of oils and fats by measuring their fatty acids. It is vital for soap production and quality control against adulteration. While the current ISO method is accurate but time-consuming, microwave-assisted extraction offers a faster, more reliable alternative for determining saponification values. In this application note, Milestone details a simple, accurate and faster method for the determination of the saponification value using ETHOS™ X together with the fastEX-24 eT rotor, reducing the preparation time and the space required to carry out the analyses.
