Quick answer: When a brand reformulates a product, for example replacing white sugar with coconut sugar or reducing sugar, sensory testing shows whether people notice a difference and whether they like the new version. Common tests include difference tests (such as the triangle test), descriptive tests with trained panels and consumer preference tests. Clear goals and good test design give reliable results.
Key takeaways – Sensory tests check whether changes are noticed and liked. – Triangle tests detect differences. – Descriptive panels describe what changed. – Consumer tests measure liking and preference.
Why test after reformulation?
Reformulation can change taste, texture, colour and aroma. A brand may want the new product to taste the same as the old one, or it may want an improved taste. Sensory testing tells you which outcome you achieved before you launch.
Which tests are common?
| Test | Question it answers |
|---|---|
| Triangle test | Can people tell the products apart? |
| Duo-trio test | Which sample matches the reference? |
| Descriptive analysis | What exactly is different? |
| Hedonic (liking) test | How much do people like it? |
| Paired preference | Which one do people prefer? |
How does a triangle test work?
Panelists receive three coded samples: two are the same, one is different. They choose the odd one out. If significantly more people than chance pick the correct sample, there is a noticeable difference. Statistical tables show how many correct answers are needed.
How many people are needed?
Difference tests often use around 20 to 40 panelists or more, depending on the risk you accept. Consumer liking tests usually need larger groups, often 50 to 100 or more target consumers. Trained descriptive panels may be smaller but meet several times.
How do you set up a test?
- Define the goal: same taste, better taste, or acceptable difference.
- Choose the right test.
- Prepare samples the same way, at the same temperature.
- Code samples with random numbers.
- Randomise serving order.
- Provide water or crackers to cleanse the palate.
- Collect and analyse results.
What changes might coconut sugar cause?
Replacing white sugar with coconut sugar often adds caramel notes and a darker colour. Panels may notice these changes. Whether that is good depends on the product. In chocolate or spiced products, the change may be welcome. In a pale vanilla product, it may need adjustment.
What happens after testing?
If the difference is not acceptable, adjust the formula and test again. If consumers prefer the new version, the brand can move to production trials and shelf-life testing. Keep records of all tests for future reference.
