Ranking and Rating tests

Difference between ranking tests and rating tests method in food sensory evaluation.

Food sensory evaluation assesses products using human senses such as taste, smell, texture, and appearance. This process is crucial for food manufacturers to improve their products and meet the demands of consumers. Ranking and rating tests are two commonly used methods in the sensory evaluation of food. While both approaches aim to evaluate food products, they have significant differences. This article will explore the differences between ranking and rating test methods in food sensory evaluation and analyses.

Ranking Tests:

Ranking tests are sensory evaluation methods that evaluate the sensory attributes of two or more products by ranking them according to a specific criterion. In a ranking test, a panel of assessors is presented with two or more samples of the same product, and they are asked to compare and rank the samples based on a particular attribute. For example, the assessors may be asked to rank the samples according to sweetness, saltiness, or bitterness. A ranking test’s findings are presented in the samples’ order of ranking, such as first, second, or third.

Ranking tests are helpful when comparing products that are significantly different in sensory attributes. They are also beneficial when the panel of assessors is small and the test needs to be quick and easy. However, ranking tests have several limitations. For example, they do not provide information about the intensity of the sensory attributes and may not be suitable for evaluating products with subtle differences.

Ranking tests are one of the most common methods used in sensory evaluation. This method involves presenting panellists with two or more product samples and asking them to rank them based on a specific attribute. For example, panellists might be asked to rank different brands of salsa based on spiciness, or they might be asked to organise different types of cheese based on the saltiness.

The ranking test method helps determine the relative quality of different products. However, it doesn’t provide any information about the intensity or magnitude of the difference between the samples. Ranking tests can also be subjective because they rely on the panellist’s individual preferences and perception of the evaluated attributes.

Rating Tests:

Rating tests are another sensory evaluation method that evaluates food products’ sensory attributes by rating them according to a specific criterion. In a rating test, a panel of assessors is presented with one sample of the product, and they are asked to rate the intensity of a particular sensory attribute on a scale. The most common scale used in rating tests is the 9-point hedonic scale, which ranges from “dislike extremely” to “like extremely.”

Rating tests involve presenting panellists with a single product and asking them to rate the intensity or magnitude of a specific attribute. This method is often used to assess a product’s overall liking or determine the intensity of a particular feature, such as sweetness or sourness.

There are two main types of rating tests: hedonic tests and descriptive tests. Hedonic tests are used to evaluate the overall liking of a product, while descriptive tests are used to assess specific attributes such as texture, flavour, or aroma. Hedonic tests typically use a scale ranging from “dislike extremely” to “like extremely,” while descriptive tests use a scale ranging from “none” to “extremely intense.”

The rating test method helps determine the intensity of a specific attribute and identify any changes in the feature due to processing or formulation changes.
