Overview

Quantification of milk powder added to fresh milk by E-Nose
The Alpha MOS FOX Electronic Nose can detect whether powdered milk has been added to fresh milk and quantify (after pasteurization) the rate of added powdered milk.

Quantification of p-cresol in milk by HERACLES E-Nose
With the Alpha MOS HERACLES Fast GC Electronic Nose, the quantification of this compound in milk can be done in a few minutes with a sensitivity that is close to human detection threshold.

Aroma differenciation of milk and milk by-products based on process and origin
The Alpha MOS FOX Electronic Nose can be used in product development to evaluate the influence of milk composition (fat, carbohydrate, protein, vitamin and mineral content) and process (heating process, etc) on the aroma profile of processed milk and milk by-products. Results are directly correlated to human experience. The technique can be used as a fast and reliable tool to assess and control product conformity. It can also differentiate samples based on origin (trademark) or can be used for quantitative application to predict results linked to the fat content, protein content, etc.

QC monitoring of caseinates with an electronic nose
The results obtained for the qualification and control of caseinate production demonstrates the ability of the FOX Electronic Nose to rapidly provide identification of unknown samples according to supplier and quality, and correlation with the sensory panel.

Testing of Cleaning in Place (CIP) process efficiency with E-Nose
The Alpha MOS GEMINI Electronic Nose is particularly suitable for controlling CIP efficiency and for ensuring repeatability, minimizing downtime, optimizing the use of detergent and water, and avoiding the use of human sensory panels.

Instrumental multi-sensory characterization of processed cheese
This study showed the interest of combining electronic nose, electronic tongue and electronic eye analyses in order to achieve a detailed sensory evaluation of food products.

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.

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.
