Sensory analysis

Electronic Nose

Because the sensorial quality of the products are key factors for success, smell and aroma analysis are very common requirements for industry. As a result, companies frequently use olfactory analysis, both during product development and quality control. The sensory analysis proposed in AlfatestLab allows an objective smell characterization of your products together with a chemical composition analysis, based on Kovats index, qualitative and quantitative analysis through statistical data processing and chemometrics.

Quality Control

The consumer expects that his favourite products have a constant sensory quality. With objective and reliable measurements, the electronic nose helps to control the sensory profile of products all through the production line:

  • Sensory conformity tests: aroma control, off-odour detection, odorous contaminant detection
  • Consumer complaints investigation and identification of odorous defects subjected to a customer claim
  • Influence of the manufacturing process on food flavoring
  • Products aroma ageing follow-up, ingredients selection based on their shelf life and the stability of their sensory profile
  • Food packaging testing: evaluation of the impact of food-contact materials on the organoleptic quality of food.

Research & Development

The sensory profile, products aroma in particular, has a strong influence on consumers’ choice and preference. Thanks to its numerous applications, the electronic nose is a precious support tool for designing new products that meet consumers’ expectations:

  • Recipe optimization to reach a target sensory profile
  • Design of innovative product with a totally unique aroma
  • Product re-design (retro-engineering) to change or improve its sensory features: new recipe, new aroma, new packaging
  • Benchmarking of competitive products based on their sensory profile
  • Change of manufacturing process or ingredients substitution (sugar-free, low carb, etc) and assessment of the impact on product aroma.
Smell of alcohol from pre-packaged sliced bread? Ethanol content measurement and identification of discriminant volatile compounds through sensory analysis

Smell of alcohol when opening a package of sliced bread? Discover why with this e-nose comparison study of four brands of pre-packaged bread and a bakery product!


Sensory benchmarking of chocolate hazelnut spreads with e-nose

Sensory analysis is an efficient tool to compare competitors’ products to the target leaders’ one in the market, to develop a new product or to improve a current one. In this study, 4 brands of chocolate hazelnut spreads were characterized to compare their aroma profiles in order timprove, re-formulate or re-engineer products.


Recycled PET packaging: olfactive quality evaluated by sensory analysis

In this study an objective and neutral olfactive evaluation through an electronic nose has been performed on recycled PET samples. The differences respect to a reference have been clearly identified, allowing to improve the recycling processes and accelerate product development.
