Overview
EN ISO 7301:2022 - Rice: Specification (ISO 7301:2021) sets minimum quality and safety specifications for rice (Oryza sativa L.) traded internationally. It applies to husked rice and milled rice (aromatic or non‑aromatic), parboiled or not, when intended for direct human consumption. The standard does not cover rice‑derived products or waxy (glutinous) rice.
Key features:
- Defines scope, terminology and kernel categories (whole, head rice, broken, chip).
- Establishes general, sensory, physical and chemical requirements.
- Provides test methods and guidance on packaging.
Key topics and technical requirements
EN ISO 7301 is focused on measurable quality and safety parameters used for trade and inspection:
- Moisture content: maximum mass fraction 15.0 % (lower limits may be specified by destination or transport/storage conditions).
- Physical contaminants (Table 1 limits, examples):
- Inorganic extraneous matter (stones, sand): max 0.5 % (mass fraction).
- Organic extraneous matter: up to 1.0 % in some husked rice categories; 0.5 % for milled rice.
- Paddy admixture: up to 2.5 % in husked rice, 0.3 % in milled rice (varies by product and parboiled status).
- Sensory and health: rice must be sound, clean, free from foreign or spoilage odours, toxic matter, and visible live insects.
- Classification of kernels: clear definitions for whole kernels, head rice, broken (large, medium, small) and chips based on average length (ISO 11746 referenced).
- Parboiled-specific terms: partly gelatinized kernels, pecks and color-related defects.
- Testing and methods: normative test procedures are given in Annex A and additional methods in Annexes B and C (e.g., determination of waxy rice in parboiled rice; stress‑cracked kernels).
Applications and users
This standard is practical for professionals involved in the rice value chain:
- Exporters / importers and traders - contract specifications, quality acceptance criteria.
- Quality assurance and laboratory personnel - sampling, testing and classification of consignments.
- Customs and regulatory authorities - compliance checks and trade facilitation.
- Procurement managers and food manufacturers - supplier selection and product specifications.
- Standardization bodies and auditors - reference for conformity assessment and contract language.
Using EN ISO 7301 helps reduce trade disputes, harmonize inspection criteria and ensure consistent rice quality across international markets.
