What is a Star Profile in Food Technology?

If you’ve ever looked at a sensory star profile and thought it looked more like a spider’s web than a graph, you’re not alone.

Star profiles are one of the most common forms of sensory analysis used in Food Technology and Hospitality and Catering, but they can sometimes feel confusing at first. Once you understand how they work, they are actually one of the easiest ways to compare food products visually.

A star profile allows us to compare the sensory characteristics of a food product by scoring different attributes and plotting them on a graph.

What is a sensory star profile?

A sensory star profile (sometimes called a radar chart or spider diagram) is used to show the strengths and weaknesses of a food product visually.

Testers score a range of sensory characteristics, usually out of 10, such as:

  • appearance
  • aroma
  • flavour
  • texture
  • sweetness
  • saltiness
  • crispiness
  • moistness

The scores are then joined together to create a star-shaped graph.

This makes it easy to identify which characteristics are strongest and which characteristics may need improvement.

Why do we use star profiles?

Star profiles are useful because they allow us to:

  • compare several products quickly
  • identify strengths and weaknesses
  • evaluate recipe modifications
  • compare tester opinions
  • justify improvements to a product

They are often used during product development and practical investigations.

Example

Imagine that we are comparing two biscuit recipes.

CharacteristicOriginal recipeReduced sugar recipe
Appearance87
Sweetness95
Texture78
Aroma87
Overall acceptability96

A star profile would immediately show that the reduced sugar recipe has lower sweetness and overall acceptability scores.

Generated using the Sensory Star profile toolkit

This helps us to identify where further improvements may be needed and draw some comparisons we can write about.

Common mistakes when using star profiles

One of the biggest mistakes students make is choosing sensory words that are too vague.

For example:

  • nice
  • bad
  • disgusting
  • tasty

Instead, try to use more specific sensory vocabulary:

  • crispy
  • buttery
  • rich
  • bland
  • sweet
  • salty
  • chewy
  • crunchy
  • moist

The more precise your sensory vocabulary, the stronger your evaluation will be.

How do I interpret a star profile?

When looking at a star profile, ask yourself:

  • Which characteristic scored the highest?
  • Which characteristic scored the lowest?
  • Are there any obvious strengths?
  • Are there any weaknesses?
  • How could the product be improved?

Remember that there is rarely a perfect product. The purpose of sensory analysis is to identify opportunities for improvement.

When should I use a star profile?

A star profile works particularly well when:

  • comparing two recipes
  • reducing sugar or salt
  • developing healthier products
  • evaluating practical work
  • comparing commercial products
  • gathering feedback from several testers

150 Sensory Words for Food Evaluation and Sensory Analysis

by

Finding the right sensory words for food can be one of the biggest challenges when carrying out sensory analysis and food evaluation. One of the barriers to carrying out sensory analysis is knowing how to describe what you can see, smell, taste and feel.

Many students fall into the trap of using words such as:

  • “nice”
  • “good”
  • “bad”
  • “disgusting”
  • “I liked it”
  • “I didn’t like it”

The problem is that these words don’t actually tell us anything useful about the food product.

For example:

“The biscuit was nice.”

What exactly was nice about it?

Was it:

  • crispy?
  • sweet?
  • buttery?
  • golden?
  • crunchy?
  • soft?
  • chewy?

The aim of sensory analysis is to use precise vocabulary to explain what you experienced and justify your opinion.

This list of sensory words for food has been designed to help students and teachers develop more detailed sensory analysis and evaluation skills.

What are sensory words?

Sensory words are descriptive words used to explain the characteristics of a food product using the senses.

When carrying out sensory analysis, we usually evaluate:

  • appearance
  • aroma
  • flavour
  • texture and mouthfeel
  • sound (where appropriate)
  • overall acceptability

Using a wider range of sensory vocabulary allows us to explain exactly what we liked, disliked or would improve.

Flavour sensory words for food

Flavour is often the area where students struggle most.

Instead of saying:

“It tasted nice.”

Try to explain exactly what you mean.

For example:

“The biscuit had a sweet, buttery flavour with a slight vanilla aftertaste.”

Sweetness and Saltiness

When developing recipes, particularly healthier products, it is important to be able to describe sweetness and saltiness accurately.

For example, if sugar or salt has been reduced, testers may need to explain whether the product:

Sweetness

  • is not sweet enough
  • has a balanced sweetness
  • is overly sweet
  • has a subtle sweetness
  • tastes artificial
  • lacks sweetness
  • has a lingering sweetness

Saltiness

  • is under-seasoned
  • has a balanced saltiness
  • is too salty
  • tastes savoury
  • lacks seasoning
  • has a strong salty flavour
  • has an overpowering salty taste

Texture and Mouthfeel sensory words for food

Texture describes how food feels in the mouth.

Instead of saying:

“The texture wasn’t very nice.”

Try to identify what the texture actually was.

Was it:

  • soggy?
  • crispy?
  • crunchy?
  • chewy?
  • dry?
  • creamy?
  • rubbery?

Sound

Some food products can also be evaluated by the sounds they make.

Positive sound words

  • crisp
  • crunchy
  • crackling
  • snappy
  • light

Negative sound words

  • soft
  • soggy
  • stale
  • muted
  • dull

Overall Evaluation

These words can help summarise your final opinion of a product.

Positive words

  • appealing
  • enjoyable
  • satisfying
  • authentic
  • high quality
  • balanced
  • well executed
  • professional
  • successful
  • effective

Negative words

  • disappointing
  • unbalanced
  • poor quality
  • artificial
  • underdeveloped
  • unappealing
  • unsuccessful
  • inconsistent
  • unsatisfactory
  • ineffective

Top Tip

If you find yourself writing:

“It was nice.”

Stop and ask yourself:

What exactly made it nice?

The best sensory evaluations explain exactly what the tester could see, smell, taste and feel. Using a wider range of sensory words for food will help improve coursework, practical evaluations and sensory testing activities.
