Overview

Instrumental odor assessment
A world leader in sensing technologies that digitize the human senses, Alpha MOS offers electronic noses based on ultra fast gas chromatography technology.

Instrumental sensory benchmarking and application to sausages
Competitive benchmarking, which consists of comparing one’s products or processes to the leaders’ ones, is a technique commonly employed by companies. This type of studies allows to position one’s products in the market versus competitors and to give indications in order to improve, re-engineer or re-formulate products.

Alpha MOS HERACLES Neo Electronic Nose
The new generation of HERACLES Neo electronic nose from Alpha MOS features unsurpassed performance in smell and flavor analysis.

Alpha MOS HERACLES Electronic Nose technical specifications
HERACLES is  an electronic nose based on dual flash gas chromatography technology dedicated to smell and aroma analysis. It allows manual injection and can also be used with an autosampler.

Alpha MOS instruments dedicated to odour, taste and visual aspect (colour and shape) analysis
Specialized in electronic sensing systems, Alpha MOS company positions as the world leader in the design and development of instruments dedicated to odour, taste and visual aspect (colour and shape) analysis. To answer the needs of the major industries, Alpha MOS offers reliable and fast solutions that can control the sensory quality of their products and secure their manufacturing processes.


New food products development with an electronic tongue and an electronic nose
This application note describes the sensory evaluation of various formulations of snacks, with an aim to select the optimized product that will meet the market expectations. Eight formulations of snacks were analysed both by a sensory panel and by E-Nose and E-Tongue. The sample set includes snacks obtained based on different manufacturing processes that lead to different textures. The samples were pulverized using blade mixer before analysis, to get homogenised samples. The panel of trained assessors used a Quantitative Descriptive Analysis based on 26 descriptors among which 7 for texture, 5 for aroma, and 14 for flavor. The combination of E-Nose and E-Tongue measurements showed the same grouping of samples as the sensory panel.

Application to spiced sauce of qualitative and quantitative product deformulation with an electronic nose
In the context of the constant evolution of taste, marketing & R&D departments sometimes need to enter a re-engineering process in order to make their current products consistently match the market expectancies. This application note describes the comparative analysis of two similar spiced sauces with the Alpha MOS Ultra Fast GC based HERACLES Electronic Nose where “Brand A” sauce represents the sauce produced by the market leader. Their aromatic profiles were first compared. Then various herbs and spices were investigated in order to screen the possible ingredients entering the formulas prior to re-formulation.


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.

Quality control of Omega-3 powders
With the Alpha MOS electronic noses, formulation
departments can achieve instrumental evaluation of aroma of Omega-3 powders in correlation with sensory panel scale, thus avoiding safety concerns while reducing human workload, and determine the optimum storage conditions for ingredients and final products.

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.
