Overview

ISO 959-2:1998 is the International Organization for Standardization specification for white pepper (Piper nigrum L.), whole or ground. This second edition defines product types, quality limits, sampling and test methods, packaging and marking requirements, plus a normative method for determining apparent bulk density. It applies to semi-processed (SP) and processed (P) commercial stages and is intended for use in trade, quality control and regulatory contexts for spices.

Key topics and technical requirements

• Definitions & product types: distinguishes whole white pepper, ground white pepper, semi‑processed (SP) and processed (P) products.
• Physical quality limits (selected values from Table 1):
  • Extraneous matter: max 1.0% (SP), 0.8% (P) by mass (ISO 927).
  • Broken berries: max 4.0% (SP), 3.0% (P).
  • Black berries: max 15% (SP), 10% (P) (Samarinda exception: 20%).
  • Apparent bulk density: min 600 g/l (Annex A method).
• Chemical requirements (Table 2):
  • Moisture: max 14.0% (ISO 939).
  • Total ash: max 3.5% on dry basis (ISO 928).
  • Volatile oils: min 1.0 ml/100 g (whole), 0.7 ml/100 g (ground) (ISO 6571) - note recommendation to measure immediately after grinding.
  • Non‑volatile ether extract: min 6.5% on dry basis (ISO 1108).
  • Piperine content: min 4.0% on dry basis (ISO 5564).
  • Ground product: acid‑insoluble ash max 0.3%, crude fibre max 6.5%.
• Sampling and test methods: sampling per ISO 948; specific analyses use referenced ISO methods listed in the standard.
• Packing & marking: packages must protect against moisture and loss of volatiles and be labeled with product name, manufacturer, batch, net mass, commercial stage (SP/P), producing country, destination and reference to ISO 959.
• Storage & transport guidance (Annex B): keep dry, ventilated, odor‑free, and protected from sun, rain, pests and contamination.

Applications and who uses it

ISO 959-2:1998 is used by:

• Spice growers and processors for defining white pepper quality grades.
• Exporters/importers and commodity traders for contract specifications and acceptance criteria.
• Food testing and quality control laboratories for standardized analytical methods (moisture, piperine, volatile oil, ash).
• Packaging and logistics teams to ensure proper packing, labeling and transport.
• Regulators and certification bodies for compliance with international spices standards.

Related standards

Normative references include ISO 959-1 (black pepper), ISO 676 (nomenclature) and test methods such as ISO 927, 928, 930, 939, 948, 1108, 1208, 5498, 5564, 6571.

Keywords: ISO 959-2:1998, white pepper specification, Piper nigrum, spice quality standards, pepper testing, piperine, volatile oil, spice packing and labeling.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
International Standard ISO 959-2 was prepared by Technical Committee TC 34, Agricultural food products,
Subcommittee SC 7, Spices and condiments.
This second edition cancels and replaces the first edition (ISO 959-2:1989), which has been technically revised.

L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux de
normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général confiée aux
comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire partie du comité
technique créé à cet effet. Les organisations internationales, gouvernementales et non gouvernementales, en
liaison avec l'ISO, participent également aux travaux. L'ISO collabore étroitement avec la Commission
électrotechnique internationale (CEI) en ce qui concerne la normalisation électrotechnique.
Les projets de Normes internationales adoptés par les comités techniques sont soumis aux comités membres pour
vote. Leur publication comme Normes internationales requiert l'approbation de 75 % au moins des comités
membres votants.
La Norme internationale ISO 959-2 a été élaborée par le comité technique ISO/TC 34, Produits agricoles
alimentaires, sous-comité SC 7, Epices.
Cette deuxième édition annule et remplace la première édition (ISO 959-2:1989), dont elle constitue une révision

ISO
4 Description
4.1 Le poivre blanc est obtenu de deux façons:
a) à partir du poivre noir en utilisant la baie entière séchée, généralement cueillie avant maturité complète, du
Piper nigrum L., et en éliminant l'enveloppe extérieure du péricarpe avec ou sans macération préalable dans
l'eau; un séchage est ensuite effectué, le cas échéant;
b) à partir de la baie entière mûre du Piper nigrum L. en éliminant l'enveloppe extérieure du péricarpe, par les
mêmes procédés que décrits ci-dessus.
Les baies de poivre blanc se présentent sous la forme de grains presque sphériques, de 3 mm à 5 mm de diamètre,
montrant une surface lisse légèrement aplatie à un pôle, et une petite protubérance au point opposé.
Les baies présentent généralement des stries verticales allant d'un pôle à l'autre, d'une couleur légèrement plus
foncée. La couleur du poivre blanc va du gris mat brunâtre au blanc ivoire pâle.
4.2  Le poivre blanc en poudre est obtenu par broyage du poivre blanc, sans aucune adjonction de matières
étrangères au poivre.
5 Exigences
5.1 Odeur et flaveur
La flaveur du poivre blanc lorsqu'il est moulu doit être caractéristique, légèrement piquante et très aromatique. Le
produit doit être exempt d'odeur et de flaveurs étrangères.
NOTE  L'aspect des baies n'est pas en relation directe avec la flaveur. De petites baies peuvent être plus aromatiques que
des baies ayant une meilleure présentation ou des dimensions supérieures.
5.2 Absence de moisissures, insectes, etc.
Le poivre blanc doit être exempt d'insectes vivants et de moisissures, et pratiquement exempt d'insectes morts, de
fragments d'insectes et de contamination par les rongeurs, visibles à l'œil nu (corrigé si nécessaire dans le cas
d'une vision anormale) ou avec le grossissement pouvant s'avérer nécessaire dans certains cas particuliers. Si le
grossissement est supérieur à · 10, mention doit en être faite dans le rapport d'essai.
Dans le cas de poivre blanc en poudre, les impuretés doivent être déterminées selon la méthode décrite dans
l'ISO 1208.
5.3 Caractéristiques physiques
Le poivre blanc entier doit répondre aux exigences données dans le tableau 1.
