A consumer's direct sensory experience with

I. Sensory analysisOVERVIEWA consumer's direct sensory experience with a product often

a product often plays a major role in that

product's market success. In order to minimize returns and maximize repeat purchases, it is crucial that a product's attributes accurately match the sensory cues delivered on product packaging and marketing collateral and meet consumer expectations. UL sensory testing services evaluate product difference, characteristic and preference attributes in order to help companies understand how their products are perceived by their target markets.

their products meet consumers' preferred sensory characteristics. Our customers gain a detailed view of consumers' responses to a tested product and a deeper understanding of that product's prospective competitive value.

how tested products will influence consumer purchase decisions and build brand loyalty.

Trained Descriptive Panels

Our customers’ products are evaluated by panels of people who are experienced in sensory science. UL uses an established framework during testing in order to help ensure standardized responses across product lines and quantitative result data.

Degree of Difference Testing

Our tests help customers know whether appreciable differences occur between test and control products, and help establish a product’s intrinsic variability rate due to variances in production time, component sourcing and other circumstances.

Substantiation and Product Optimization
UL’s testing and analysis help customers verify their advertising, packaging and marketing claims and assist in their efforts to maximize consumer satisfaction potential.

On-site Sensory Testing and Product Evaluations

UL can help customers create in-house programs using accepted sensory testing methods in order to evaluate specific product attributes.

Consumer tastes, preferences

II. Sensory analysis of food productsConsumer tastes, preferences and buying behaviours

and buying behaviours are changing constantly. Researchers at the

Health and Food Sciences Precinct can help your business:
understand your target market characteristics
define products and their acceptability
test product concepts
understand product quality issues.

food and beverage products

Sensory analysis can reveal how consumers

perceive the appearance, aroma, taste and texture of your product. Testing includes:

difference testing to understand if new product formulations differ in taste and texture from old ones
shelf-life trials (in combination with microbial count testing)
acceptability testing to understand if a product suits consumer palates
flavour profiling to identify consumer preferences for product
fault detection to identify undesirable flavours.

Consumer research for

II. Sensory analysis of food productsConsumer research for food and beverage

food and beverage products

Consumer research gives you information about

potential customers. We use focus groups, surveys, experimental auctions, at-home trials and novel interview methods to understand how consumers think and feel about food and beverage products.
Some of the ways our methods have helped business and industry include:
product concept and prototype testing
domestic and export market consumer profiles
customer motivation and how this can shape marketing strategies
demand, purchase intent and consumer willingness to pay
consumer threshold for defects.

III. Sensory TestingSensory analysis (or sensory evaluation) is a scientific discipline that applies principles of experimental

applies principles of experimental design and statistical analysis to the use of human senses (sight, smell, taste, touch and hearing)

for the purposes of evaluating consumer products. The discipline requires panels of human assessors, on whom the products are tested, and recording the responses made by them. By applying statistical techniques to the results it is possible to make inferences and insights about the products under test. Most large consumer goods companies have departments dedicated to sensory analysis. Sensory analysis can mainly be broken down into three sub-sections:
Effective testing (dealing with objective facts about products)
Affective testing (dealing with subjective facts such as preferences)
Perception (the biochemical and psychological aspects of sensation)

concerned with obtaining objective facts about products. This could range from

basic discrimination testing (e.g. Do two or more products differ from each other?) to descriptive profiling (e.g. What are the characteristics of two or more products?). The type of panel required for this type of testing would normally be a trained panel.

There are several types of

III. Sensory TestingEffective testingThere are several types of sensory tests. The

sensory tests. The most classic is the sensory profile.

In this test, each taster describes each product by means of a questionnaire. The questionnaire includes a list of descriptors (e.g., bitterness, acidity, etc.). The taster rates each descriptor for each product depending on the intensity of the descriptor he perceives in the product (e.g., 0 = very weak to 10 = very strong). In the method of Free choice profiling, each taster builds his own questionnaire.
Another family of methods is known as holistic as they are focused on the overall appearance of the product. This is the case of the categorization and the napping.

type of testing is concerned with obtaining subjective data, or how

well products are likely to be accepted. Usually large (50 or more) panels of untrained personnel are recruited for this type of testing, although smaller focus groups can be utilised to gain insights into products. The range of testing can vary from simple comparative testing (e.g. Which do you prefer, A or B?) to structured questioning regarding the magnitude of acceptance of individual characteristics (e.g. Please rate the "fruity aroma": dislike|neither|like).

possible to explain why certain characteristics are preferred over others. When sensory analysts study the relationship between a given physical stimulus and the subject's respons, the outcome is often regarded as a one-step process. In fact, there are at least three steps in the process. The stimulus hits the sense organ and is converted to a nerve signal that travels to the brain.The brain then interprets, organizes and integrates the incoming sensations into perceptions. Finally, a response is formulated based on the subject's perceptions.
