Sensory analysis of coffee and tea products with Alpha MOS analytical instruments

Alpha MOS electronic sensing instruments are aimed at analyzing the chemical and sensory properties of products, in a way which correlates well with the results obtained by human sensory panels. Alpha MOS electronic sensing instruments have many applications in the coffee and tea industry.

Now 25 years in business, Norlab is a specialist supplier of Separation Science & Dissolution Instruments and Accessories, Laboratory Fluid Handling Solutions and more...
To celebrate our 25th anniversary, we are planning special deals and promotions throughout the year. We encourage you to stay informed by signing up for our newsletter.

Competitive benchmarking and development of new coffee products with e-tongue
The Alpha MOS ASTREE Electronic Tongue system offers higher speed of analysis than traditional techniques, thanks to its global analysis of products, and helps manufacturers speed up competitive benchmarking and new product development process. This study describes some examples of the possibilities offered by the Alpha MOS Electronic Tongue.

Coffee bitterness determination with an electronic tongue
The Alpha MOS ASTREE Electronic Tongue can be used to determine the bitterness level of various coffee preparations. After building a bitterness scale with the e-tongue from coffees tested by a sensory panel, the instrument can then be used to assess bitterness of components extracted from coffee.


Monitoring quality of coffee supplies with an electronic nose
The Alpha MOS HERACLES Electronic Nose can be successfully employed to control the quality of coffee samples and detect aged products. HERACLES is a very powerful tool to rapidly assess the sensory quality of coffee batches upon receipt and to select suppliers.

Organoleptic testing and sensory comparison of teas with an electronic tongue
The Alpha MOS ASTREE Electronic Tongue is a fast, objective, flexible and cost effective tool to perform the organoleptic testing and sensory comparison of teas. The data obtained in this study demonstrated the repeatability and accuracy of ASTREE for discriminating and comparing teas according to flavors, origins, process techniques, blending, etc, for evaluating bitterness, or for evaluating the influence of steeping time. It is a powerful tool for tea quality control, providing significant benefits compared to other techniques or human sensory panels.

Batch cross contamination monitoring in tea processing with an electronic nose
With the Alpha MOS HERACLES Electronic Nose, based on ultra fast Gas Chromatography, low levels of contaminants in food and beverage products can be measured in a very short time (every 4 minutes).


The Electronic Nose and Tongue: a powerful marketing and sales tools in the Japanese food and beverage industry

In Japan electronic nose and tongue instruments have been widely used as Research and Development tools particularly in the food, beverage and cosmetics industries for shelf life analysis or formulation developments. They are more and more used nowadays at the production floor as easy, reliable and fast organoleptic Quality Control instruments. They do give simple electronic signature correlated with the smell and taste qualities (quantitative or qualitative). They can also provide a chemical firewall instrument or early warning process indicators of any changes in the raw materials profiles or finished products qualities.

Electronic Nose and Tongue instruments are now included in sales and marketing tools. They are used by vendors in order to:

  • Guarantee objectively the batch to batch consistency of products to their customers by providing an electronic signature on every lot delivered
  • Outrun competitors by showing objective specifications of their products
  • Position their products versus competition

Electronic Nose and Tongue instruments can be not only part of a manufacturer's specifications under an electronic signature format within relationships with customers or suppliers, but they can also be used as powerful tools to objectivate the organoleptic the specifications of a manufacturer’s products.

This article presents examples where the Electronic Nose and Tongue are part of the marketing and sales efforts of food companies in Japan.

Alpha MOS HERACLES Flash Gas Chromatography Electronic Nose
The HERACLES II is the most powerful and flexible electronic nose. This all-in-one instrument, both electronic nose and ultra fast gas chromatograph, performs overall odor profiling and chemical composition analysis in one run.


Alpha MOS ASTREE Electronic Tongue
ASTREE is the key tool for objective and safe taste assessment: taste masking, shelf life studies, taste comparison, etc.
