Overview

ISO 20984:2020 sets the international specification and test methods for fresh Cornelian cherry fruit, derived from the tree Cornus mas L. This standard aims to ensure consistent quality, safety, and proper classification for fresh Cornelian cherries marketed globally. Notably, ISO 20984:2020 applies exclusively to fresh fruit and does not cover processed Cornelian cherries. Published by the International Organization for Standardization (ISO) in June 2020, the document provides detailed requirements on classification, tolerances, testing, packaging, storage, and hygiene.

Key Topics

• Scope and Application
  Defines requirements for fresh Cornelian cherries to maintain standardization in international trade and quality control.
• Classification System
  Cornelian cherries are categorized into five color groups-yellow, red, white, pink, and violet. They are further divided into three quality classes, namely Extra class (superior quality), Class I (good quality), and Class II (minimum acceptable quality) based on diameter and appearance.
• Quality Requirements
  Fresh Cornelian cherries must be whole, sound, clean, free from foreign matter, pests, rots, and have a fresh appearance and smell. Specific size ranges and defect tolerances are defined for each class.
• Test Methods
  Includes internationally recognized procedures to assess titratable acidity, water-insoluble solids, mineral impurities, pH, and soluble solids content in the fruit. These methods rely on related ISO standards (e.g., ISO 750, ISO 751, ISO 762).
• Sampling Procedures
  Sampling policies align with ISO 874 and ISO 2859-1 to ensure representative and statistically valid analysis of Cornelian cherry lots.
• Packaging and Labelling
  Specifies packaging materials should protect the fruit and avoid contamination. Mandatory labelling details include product name, producer, batch code, net or gross mass, product class, country of origin, expiry date, and optional reference to the ISO 20984 standard.
• Storage and Transportation
  Guidance mandates that cherries must be stored in shade, protected from rain, cold, and freezing conditions during transport and handling.
• Safety and Hygiene
  Recommends adherence to Codex Alimentarius guidelines on contaminants and pesticide residues, ensuring food safety for consumers.

Applications

ISO 20984:2020 is essential for:

• Growers and Producers: Provides clear grading and quality control criteria to maintain consistency in fresh Cornelian cherry harvests.
• Exporters and Importers: Facilitates international trade by standardizing product quality, packaging, and labelling requirements.
• Quality Inspectors and Laboratories: Offers standardized methods for physical and chemical testing, enabling reliable quality assessments.
• Retailers and Distributors: Helps ensure the fruit received meets specified quality standards, improving consumer satisfaction.
• Food Safety Authorities: Assists in the enforcement of hygiene, contaminant, and pesticide residue controls in fresh produce markets.

Related Standards

ISO 20984:2020 references and complements various ISO standards that cover fruit testing and sampling processes:

• ISO 874 – Fresh fruits and vegetables - Sampling
• ISO 2859-1 – Sampling procedures for inspection by attributes
• ISO 750 – Determination of titratable acidity in fruit and vegetable products
• ISO 751 – Determination of water-insoluble solids
• ISO 762 – Determination of mineral impurities content
• ISO 1842 – Determination of pH
• ISO 2173 – Determination of soluble solids (refractometric method)

Additionally, hygiene guidelines reference Codex Alimentarius codes such as CAC/RCP 1-1969 and CAC/RCP 53-2003, along with CODEX STAN 193-1995 for pesticide residues.

Ensure compliance with ISO 20984:2020 to guarantee fresh Cornelian cherries meet internationally recognized quality and safety standards, facilitating reliable trade and consumer confidence worldwide.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
