Comprehensive Guide to ISO 11287 Determination of Sulfite Levels in Dried Fruits Laboratory Testing Service by Eurolab

ISO 11287:2017 is the international standard for determining sulfite levels in dried fruits. This standard is published by the International Organization for Standardization (ISO) and is widely recognized as a benchmark for laboratory testing services worldwide. The standard specifies the requirements for the determination of sulfite levels in dried fruits, including the sampling method, sample preparation, and measurement techniques.

Legal and Regulatory Framework

The use of sulfites in food products is regulated by various international and national authorities, including the European Food Safety Authority (EFSA), the US FDA, and the International Code of Conduct on Detergents. The ISO 11287 standard is designed to ensure that laboratory testing services comply with these regulations and provide accurate results.

International and National Standards

The following standards are relevant to the determination of sulfite levels in dried fruits:

  • ISO 11287:2017

  • EN ISO 11287:2018 (European standard)

  • ASTM D 3436-98 (American standard)

  • TSE 1331 (Turkish standard)

    • Standard Development Organizations
