Overview
EN ISO 11747:2012/A1:2018 is an important amendment to the international standard focused on the determination of rice kernel resistance to extrusion after cooking. Originally published as ISO 11747:2012, this amendment refines and updates testing protocols to improve accuracy, repeatability, and reproducibility of extrusion resistance measurements. Developed by ISO/TC 34 (Food Products) in collaboration with CEN/TC 338 (Cereal and Cereal Products), this standard specifically applies to the quality assessment of cooked rice kernels through mechanical extrusion methods. The amendment was officially adopted by CEN in November 2017 and published in March 2018 to support consistent and reliable rice quality testing across European and international laboratories.
Key Topics
Scope and Purpose
This standard targets the measurement of rice kernel texture by assessing resistance to extrusion after cooking. Resistance to extrusion is a critical indicator of rice firmness and texture, important for quality control in rice processing, breeding, and product development.Methodology Updates
Amendment 1 revises key sections describing the repeatability and reproducibility of test results:- Repeatability: The maximum absolute difference between two test results within the same laboratory should not exceed a repeatability limit of 0.064 kg/cm in 95% of cases.
- Reproducibility: Differences between test results from different labs are controlled by a reproducibility limit formula dependent on mean extrusion resistance.
Statistical Data and Validation
The amendment includes updated statistical analyses for cooked rice samples tested across multiple laboratories, delivering validated performance criteria for the test method. Tables detail mean values, standard deviations, coefficients of variation, and repeatability and reproducibility limits, ensuring method robustness.Standard Implementation
CEN member countries, including Austria, Germany, France, the UK, and others, are required to adopt this standard as a national standard to ensure harmonization of rice quality testing procedures.
Applications
Rice Quality Control
Manufacturers and quality assurance labs use this standard to accurately characterize rice kernel texture after cooking. The extrusion resistance data helps in grading rice batches and ensuring consistency in cooked rice firmness, which affects consumer satisfaction.Rice Breeding and Research
Plant breeders utilize this method to assess texture traits in rice varieties, facilitating selection of cultivars with desired cooking and eating qualities.Food Product Development
Food scientists apply the test to optimize processing parameters and ingredient formulations, especially in ready-to-eat rice products and rice-based convenience foods.Regulatory and Trade Compliance
Compliance with EN ISO 11747:2012/A1:2018 supports conformity to international food quality standards, fostering fair trade and meeting import/export requirements.
