Sensory analysis - Methodology - General guidance for establishing a sensory profile (ISO 13299:2003)

ISO 13299:2003 describes the overall process for developing a sensory profile. Sensory profiles can be established for products such as foods and beverages, and can also be useful in studies of human cognition and behaviour. Some applications of sensory profiling are:
to develop or change a product;
to define a product, production standard or trading standard in terms of its sensory attributes;
to study and improve shelf-life;
to define a reference fresh product for shelf-life testing;
to compare a product with a standard or with other similar products on the market or under development;
to map a product's perceived attributes for the purpose of relating them to factors such as instrumental, chemical or physical properties, and/or to consumer acceptability;
to characterize by type and intensity the off-odours or off-tastes in a sample of air or water (e.g. in pollution studies).

Sensorische Analyse - Prüfverfahren - Allgemeiner Leitfaden zur Erstellung eines sensorischen Profils (ISO 13299:2003)

Die vorliegende Internationale Norm beschreibt den Gesamtprozess der Erstellung eines sensorischen Profils. Sensorische Profile können für Prüfmaterialien, wie z. B. Lebensmittel und Getränke, erstellt werden, sie können auch nützlich bei der Untersuchung der menschlichen Wahrnehmung und des menschlichen Verhaltens sein. Einige Anwendungen der Erstellung sensorischer Profile sind z. B:
-   Entwicklung oder Änderung eines Produkts;
-   Definition eines Prüfmaterials, Produktionsstandards oder Handelsstandards in Bezug auf dessen sensorische Merkmalseigenschaften;
-   Untersuchung und Verbesserung der Haltbarkeitsdauer;
-   Definition eines „frischen“ Referenzprüfmaterials für die Prüfung der Haltbarkeitsdauer;
-   Vergleich eines Prüfmaterials mit einem Standard oder mit gleichartigem Prüfmaterial, das sich auf dem Markt oder in der Entwicklung befindet;
-   Kartographisieren der wahrgenommenen Merkmalseigenschaften eines Prüfmaterials, um sie auf Faktoren, wie z. B. instrumentelle, chemische oder physikalische Eigenschaften, und/oder die Akzeptanz der Verbraucher zu beziehen;
-   Charakterisierung von Fremdgeruch oder Fremdgeschmack in einer Luft- oder Wasserprobe nach seiner Art und Intensität (z. B. bei Studien zur Umweltverschmutzung).
ANMERKUNG 1   Sensorische Profile können auch für Nicht-Lebensmittel-(Non-Food-)Prüfmaterialien oder  Proben erstellt werden, die mit Hilfe des Gesichts , Geruchs , Geschmacks , Tast- oder Gehörsinns bewertet werden.
ANMERKUNG 2   Einige Internationale Normen, in denen Aspekte der Erstellung eines sensorischen Profils behandelt werden, sind in den Abschnitten 2 und 4 angeführt.

Analyse sensorielle - Méthodologie - Directives générales pour l'établissement d'un profil sensoriel (ISO 13299:2003)

L'ISO 13299:2003 décrit le processus d'ensemble d'établissement d'un profil sensoriel. Les profils sensoriels peuvent être établis pour des produits tels que les aliments et les boissons, et peuvent également être utiles dans l'étude de la cognition et du comportement humain. Certaines applications du profil sensoriel sont:
la mise au point ou la modification d'un produit;
la définition d'un produit, d'une norme de production ou bien d'une norme commerciale en termes de propriétés sensorielles;
l'étude et l'amélioration de la durée de conservation;
la définition d'un produit frais de référence pour les essais de conservation;
la comparaison d'un produit avec un étalon ou avec d'autres produits similaires sur le marché ou en cours de développement;
l'établissement de la liste des propriétés perçues du produit afin de les relier à des facteurs tels que les propriétés instrumentales, chimiques ou physiques, et/ou à l'acceptabilité pour les consommateurs;
la caractérisation du type et de l'intensité des odeurs et des goûts atypiques dans un échantillon d'air ou d'eau (par exemple dans les études en matière de pollution).

Senzorična analiza - Metodologija - Splošno navodilo za uvajanje senzoričnega profila (ISO 13299:2003)

Ta mednarodni standard opisuje celoten postopek za razvijanje senzoričnega profila. Senzorični profili se lahko uvajajo za proizvode, kot so hrana in pijača, uporabni pa so lahko tudi pri študijah človeškega znanja in vedenja. Nekatera področja uporabe senzoričnega profiliranja so:
za razvijanje ali spreminjanje proizvoda;
za opredelitev proizvoda, proizvodnega standarda ali trgovinskega standarda glede senzoričnih lastnosti;
za preučevanje in izboljšanje roka trajanja;
za opredelitev referenčnega “svežega” proizvoda za preskušanje roka trajanja;
za primerjanje proizvoda s standardom ali z drugimi podobnimi proizvodi na trgu ali v postopku razvijanja;
za razporejanje zaznanih atributov proizvoda z namenom povezave z dejavniki, kot so uporabne, kemične ali fizične lastnosti in/ali uporabniška sprejemljivost;
za opredelitev po vrsti in jakosti neprijetnih vonjev ali neprijetnih okusov v vzorcu ali zraku ali vodi (npr. v
študijah onesnaževanja).
OPOMBA 1: Senzorični profili se lahko uvajajo tudi za neprehrambene proizvode ali vzorce, ki se ocenjujejo s čutili vida, vonja, okusa, otipa ali sluha. OPOMBA 2: Nekateri mednarodni standardi, ki obravnavajo vidike uvajanja senzoričnega profila, so podani v Klavzuli 2 in 4.

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 2.
The main task of technical committees is to prepare International Standards. 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.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO 13299:2003(E)
Introduction
The purpose of this International Standard is to serve as guidance on those steps that are common to all
sensory profiling. Reference is given in Clause 4 to existing and planned International Standards describing a
part of the process (e.g. the choice of descriptors or of scales) or describing specific types of sensory profiling
(e.g. texture or flavour profiles).
A sensory profile is a descriptive analysis of a sample by a panel. The sample may be a product (e.g. a food,
beverage, tobacco product, cosmetic, textile or paper). It could also be a sample of air or water being tested
for pollutants. Profiling can be carried out in a number of ways. Over the years, a few of these have been
formalized and codified as descriptive procedures by professional societies or by groups of producers and
users for the purpose of improving communication between themselves. The purpose of this International
Standard is to provide agreed guidelines for such descriptive procedures.
Sensory profiling is based on the concept that the sensory impression made by the sample consists of a
number of identifiable sensory attributes (descriptors), each of which is present to a larger or smaller degree.
The list of all relevant sensory descriptors, each with its intensity value, is the sensory profile. Some sensory
profiles take a view across all of the senses; others (partial profiles) concentrate in detail on particular senses.
Two samples may be different yet have the same partial profile. Usually the attributes are listed in the order of
perception.
Three factors need particular attention when establishing a profile:
 that assessors differ in their sensitivity and thresholds by which they sense individual attributes;
 that assessors may lack awareness or cognizance of certain attributes of a sample; and
 that in most samples there exists a “complex” or “background” of attributes that are not easily identified or
separated.
The impact of these factors can be greatly reduced, but not entirely eliminated, by putting more effort into the
selection of descriptors, and by using larger numbers of repeat tests by larger numbers of sensitive and highly
trained assessors.
