Overview
SIST ISO 2256:1997 is an international standard published by the International Organization for Standardization (ISO) that outlines the specifications for dried mint (spearmint), formally known as Mentha spicata Linnaeus, also referred to as Mentha viridis Linnaeus. This standard defines the requirements for dried mint leaves in whole, broken, or rubbed form, including artificially dehydrated mint. It specifically does not cover dried peppermint, which is addressed in ISO 5563.
SIST ISO 2256:1997 aims to ensure the quality, safety, and consistency of dried spearmint as an agricultural product and spice, providing guidelines for sampling, testing, packing, marking, storage, and transport.
Key Topics
- Product Specifications: Defines dried mint as leaves harvested prior to or at the onset of flowering, available whole, broken, or rubbed. The leaves should exhibit a dull green or greyish-green color.
- Quality Requirements:
- Mint must possess a strong, characteristic sweet flavour and odour, free from earthy, decaying, or foreign odours.
- Dried mint must be free from living insects, mould, and rodent contamination, and should have minimal extraneous matter (less than 1% by weight of other plant species).
- Sampling & Testing: Specifies procedures for sampling (ISO 948) and methods for testing moisture, ash, acid-insoluble ash, and volatile oil content with references to relevant ISO methods.
- Packing & Marking: Dried mint should be loosely packed in cases, boxes, or sacks lined with paper to prevent moisture intrusion, with clear labelling of product name, origin, batch code, and other purchase-specific details.
- Storage & Transport: Recommends storage in dry, odorless, pest-proof, ventilated conditions, protected from sun, rain, or excessive heat, to maintain product quality throughout the supply chain.
Applications
SIST ISO 2256:1997 delivers significant value across several sectors:
- Food Industry: Ensures that dried spearmint meets international quality and safety benchmarks, reinforcing consumer confidence and promoting safe use in seasonings and condiments.
- Agricultural Exporters: Provides clear guidelines for dried mint quality, facilitating fair trade and market access by meeting the expectations of importers in various countries.
- Manufacturers & Distributors: Standardizes packaging and marking requirements, supporting efficient inventory management, traceability, and compliance with international labeling regulations.
- Quality Control Laboratories: Offers standardized test methods to verify moisture content, ash values, and volatile oil content, helping authenticate product compliance and detect adulteration.
- Supply Chain Management: Recommends best practices for storage and transport, including protection from environmental contaminants and pests, to extend shelf life and preserve the integrity of dried mint during distribution.
