Overview
SIST EN ISO 11052:2007 specifies a standardized method for the determination of yellow pigment content in durum wheat flour and semolina (Triticum durum L.). Published by the Slovenian Institute for Standardization (SIST), this standard adopts the methods outlined in ISO 11052:1994 and EN ISO 11052:2006. The yellow pigment, primarily carotenoids, is a key quality attribute influencing the appearance of durum wheat products such as pasta.
This internationally harmonized standard is essential for food manufacturers, laboratories, and quality control organizations seeking consistent and reliable measurement of yellow pigment levels to ensure product quality and compliance across global markets.
Key Topics
- Analytical Method: Describes the photometric determination of yellow pigment content after extracting carotenoids with water-saturated n-butanol.
- Scope: Applies specifically to durum wheat flour and semolina, important for pasta production and related products.
- Quality Control: Facilitates uniform assessment and comparison of yellow pigment content, critical for food appearance and consumer acceptance.
- Reproducibility: Provides guidance on repeatability and precision to support interlaboratory consistency.
- Sample Preparation: Outlines requirements for representative samples and correct particle size for accurate measurement.
- Reporting: Specifies data to be included in test reports, ensuring full transparency and traceability.
Applications
SIST EN ISO 11052:2007 is widely recognized in the food industry, especially in cereal and milling sectors. Its key practical applications include:
- Food Manufacturing Quality Assurance: Used by pasta and semolina producers to ensure that the flour and semolina meet required color specifications, directly impacting consumer preference.
- Lab Testing and Certification: Laboratories employ this standard for official testing, certification, and labeling of durum wheat flour products.
- Trade and Compliance: Provides a harmonized reference to meet international and European Union regulations, facilitating exports and imports of durum wheat products.
- Research and Development: Essential for plant breeders and agricultural researchers aiming to develop durum wheat varieties with optimized color properties.
- Supplier Qualification: Helps manufacturers assess the quality and consistency of raw materials sourced from different suppliers.
