What is EN ISO 3961:2018?

EN ISO 3961:2018 is an international standard that provides guidelines and specifications for the determination of the acid value of fats and oils. It is a method used in the food industry to assess the quality and purity of various edible oils and fats.

The Importance of Determining the Acid Value

The acid value of a fat or oil indicates the level of free fatty acids present in it. This parameter is crucial because high acid values suggest rancidity or deterioration of the product, affecting its sensory attributes and overall quality. By determining the acid value, manufacturers can ensure that their edible oils and fats meet the required standards and are safe for consumption.

How is Acid Value Determined?

The determination of the acid value involves measuring the amount of base required to neutralize the free fatty acids present in a sample of fat or oil. The procedure outlined in EN ISO 3961:2018 includes several steps, such as weighing the sample, dissolving it in a solvent, and titrating it with a standardized base solution. The acid value is calculated based on the volume of the base solution consumed during the titration process. The standard also specifies the necessary equipment, reagents, and calculations involved in obtaining accurate results.

Benefits and Applications

The application of EN ISO 3961:2018 benefits both producers and consumers. For manufacturers, it ensures consistent quality control and compliance with international standards. They can monitor the acid values of their products throughout the production process, identifying any potential issues and taking corrective measures. Consumers are assured of the safety and quality of the oils and fats they consume, as products tested according to this standard adhere to strict quality parameters. Additionally, EN ISO 3961:2018 facilitates fair trade by providing a common evaluation method and enabling comparison of acid values across different brands and products.

In conclusion, EN ISO 3961:2018 is a crucial international standard that determines the acid value of fats and oils. Its application ensures quality control, enhances food safety, and enables fair trade practices in the edible oil and fat industry.
