“…An example of application of an e-nose for olive oils is the study by Guadarrama et al (2001) who used a sensor array based on 16 conducting polymer gas sensors to discriminate the quality, variety, and geographical origin of olive oils. The PCA revealed that the e-nose applied in the study has been able to distinguish not only different-quality olive oils (lampante, ordinary, virgin, and extra virgin) but also Spanish olive oils produced from different varieties of olives and originated from different geographical areas.…”

Electronic Nose as a Tool for Monitoring the Authenticity of Food. A Review

Counterfeiting of food is recently one of the risks relevant for producers, distributors, retailers, consumers, and national governments from economic (price), health (allergens), and religious reasons. Flavour of several food products is one of the key attributes of their quality and authenticity. In the case of some foods, the aroma of a product is specific enough to discriminate an original product from its fraud or adulterated counterpart. Electronic nose (e-nose) is a rapid and powerful technique, which requires no special sample preparation to determine the aroma of a product. In the present review, the applications of different e-noses and chemometrics for determination of food authenticity including adulteration and confirmation of origin are discussed. E-noses of various configurations are a very promising tool for testing the authenticity of food products.

“…1) using olives from Chemlali or Sahli autochthonous varieties. From these, 34 samples were Chemlali olive oil, the predominant autochthonous olive variety, produced in Kairouan (16), Sfax (14) and Sidi Bouzid (four samples) regions. The other 26 samples of Sahli olive oil were produced in Kairouan (four), Mahdia (ten) and Sousse (12) regions.…”

correct prediction (repeated K-fold cross-validation) of the geographic production region with sensitivities of 92 ± 7% (Chemlali) and 97 ± 8% (Sahli). It was also confirmed the electronic tongue capability to classify Tunisian olive oil according to olive cultivar or quality grade. The results indicated the possible use of potentiometric fingerprints as a promising innovative strategy for olive oil analysis allowing assessing geographical origin, olive cultivar and quality grade, which are key factors determining olive oil price and consumers' preference.

“…More recently, ENs have been used for the quality control and process monitoring of foodstuffs such as olive oil (20,21) and milk (32). However, the potential of the EN as a diagnostic tool is attracting an increasing number of research groups for the diagnosis of infectious diseases such as bacterial vaginosis (6) and pulmonary (29) and urinary tract infections (1,39), as well as breath analyses of patients suffering from diabetes (53), uremia (30), or lung cancer (12).…”

Use of an Electronic Nose To DiagnoseMycobacterium bovisInfection in Badgers and Cattle

et al. 2005

It is estimated that more than 50 million cattle are infected with Mycobacterium bovis worldwide, resulting in severe economic losses. Current diagnosis of tuberculosis (TB) in cattle relies on tuberculin skin testing, and when combined with the slaughter of test-positive animals, it has significantly reduced the incidence of bovine TB. The failure to eradicate bovine TB in Great Britain has been attributed in part to a reservoir of the infection in badgers (Meles meles). Accurate and reliable diagnosis of infection is the cornerstone of TB control. Bacteriological diagnosis has these characteristics, but only with samples collected postmortem. Unlike significant wild animal reservoirs of M. bovis that are considered pests in other countries, such as the brushtail possum (Trichosurus vulpecula) in New Zealand, the badger and its sett are protected under United Kingdom legislation (The Protection of Badgers Act 1992). Therefore, an accurate in vitro test for badgers is needed urgently to determine the extent of the reservoir of infection cheaply and without destroying badgers. For cattle, a rapid on-farm test to complement the existing tests (the skin test and gamma interferon assay) would be highly desirable. To this end, we have investigated the potential of an electronic nose (EN) to diagnose infection of cattle or badgers with M. bovis, using a serum sample. Samples were obtained from both experimentally infected badgers and cattle, as well as naturally infected badgers. Without exception, the EN was able to discriminate infected animals from controls as early as 3 weeks after infection with M. bovis, the earliest time point examined postchallenge. The EN approach described here is a straightforward alternative to conventional methods of TB diagnosis, and it offers considerable potential as a sensitive, rapid, and cost-effective means of diagnosing M. bovis infection in cattle and badgers.
