Overview
EN 1185:1994 is a European standard developed by CEN that specifies a precise method for determining the sulfur dioxide (SO2) content in starches and starch-derived products. The method described is an acidimetric titration technique based on the modified ISO 5379:1983 procedure. This standard is crucial for ensuring the quality and safety of starch products by accurately quantifying residual sulfur dioxide, which is commonly used as a preservative and bleaching agent.
Key Topics
-
Scope of Analysis
EN 1185:1994 applies specifically to starches and their derived products, providing a standardized approach to measure their sulfur dioxide content accurately.
-
Acidimetric Method
The procedure involves an acidimetric titration technique, which uses an acid-base reaction to quantify sulfur dioxide concentrations. This standardized method offers repeatability and reliability for laboratory testing.
-
Modified ISO 5379:1983
The method is adapted from the international ISO 5379:1983, ensuring alignment with global testing practices while incorporating necessary modifications for European applications.
-
Quality Control and Compliance
Determining sulfur dioxide content is essential for manufacturers and regulators to comply with food safety regulations and quality standards.
Applications
-
Food Industry
Starches are widely used in food manufacturing as thickeners, stabilizers, and fillers. Monitoring sulfur dioxide ensures compliance with legal limits and prevents potential health risks from excessive residues.
-
Quality Assurance Laboratories
QC labs employ EN 1185:1994 to routinely test incoming raw starch materials and finished products to verify sulfur dioxide levels meet specified tolerances.
-
Regulatory Testing
Government agencies and food safety bodies use the standard to enforce regulations relating to allowable sulfur dioxide content in starch-based products.
-
Research and Development
R&D units utilize the method to analyze formulation changes and understand the impact of processing on sulfur dioxide retention.
