“…The possibility of application of an e-nose based on MOS sensors (five tin dioxide gas (TGS) sensors) and pattern recognition techniques such as PCA, DFA, and SVM to detect adulteration of argan oil with sunflower oil (from 10 to 70%) was reported by Bougrini et al (2014). Results of PCA and DFA performed on the e-nose data showed differentiation between pure and adulterated argan oils.…”

“…Actually, most of the applications listed in Table 1 were studied using e-noses based on MOS. E-noses based on conductometric sensors have been used for geographical origin confirmation or adulteration detection of dairy products (Cevoli et al 2011;Pillonel et al 2003;Yu et al 2007), plant oils (Bougrini et al 2014;Cerrato Oliveros et al 2002;Cosio et al 2006;Guadarrama et al 2001;Haddi et al 2011;Hai and Wang 2006;Jeleń 2008, Mildner-Szkudlarz andWei et al 2015), meat and meat products (Laureati et al 2014;Tian et al 2013), honey Pei et al 2015;Subari et al 2012;Subari et al 2014;Zakaria et al 2011), beverages (Aleixandre et al 2008;Berna et al 2009;Hong et al 2014;Lozano et al 2007;Penza and Cassano 2004;Steine et al 2001), coffee (Buratti et al 2015), tea (Kovács et al 2010), and some spices (Banach et al 2012;Heidarbeigi et al 2015).…”

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.

Diagnosis of adulteration in cow ghee is one of the key concerns of recent years. In this study, the aroma fingerprints of cow ghee were detected. For this purpose, an electronic nose system was developed and its ability for detection of different amounts of margarine mixed with pure cow ghee (10, 20, 30, 40, and 50% levels) was investigated. The system was equipped with eight sensors (MOS type), that each of them reacts to specific volatile compounds in the samples. The features of the signals were considered for data analysis. In this research, principal components analysis (PCA) and artificial neural networks (ANN) methods were used for data analyzing. According to the results, the PCA analysis explained 98% of the variance in the data set. Also, ANN analysis identified 85.6 and 97.2% of pure cow ghee from the adulteration ones when samples were classified in 7 and 2 classes, respectively. Practical applications Diagnosis and estimation of adulteration in cow ghee is one of the key concerns for consumers. Electronic nose is a new method that can be used for detection of products quality. We show that electronic nose system is a valuable tool for detection of margarine as a one of common adulteration in cow ghee.

“…This method ascertains argan oil purity up to 98% (Hilali et al, 2007). Adulteration of argan oil with sunflower oil can also be detected using the combination of a voltammetric e-tongue and an e-nose based on metal oxide semiconductor sensors and pattern recognition techniques (Bougrini et al, 2014). Trace element analysis has also been reported as a method to detect argan oil adulteration (Gonzalvez et al, 2010;Mohammed et al, 2013).…”

-The "argan oil project" is nowadays considered as an economic success that harmoniously combined sustainable development, integrated research-action and socio-economic progress. Actually, it was a long battle whose main stages are presented here. The main stages of the argan oil project include a detailed chemical study of argan oil in order to certify argan oil quality and establish an official quality norm and obtain a geographic indication, pharmacological analyses to certify cosmetic argan oil safety, and finally a strong desire to develop Moroccan rural areas by implementing women's cooperatives and easing the women's access to education.Keywords: argan oil / edible oil / cosmetic oil / Morocco / field research Résumé -Le projet arganier : 20 ans pour passer de l'utopie à la réalité.. Le « projet arganier » est considéré comme un succès économique qui a mélangé harmonieusement le développement durable, la recherche-action intégrée et le progrès économique et social. En réalité, ce fut une longue bataille dont les principales étapes sont présentées ci-après. Les étapes principales du projet huile d'argan comprennent une étude chimique détaillée de l'huile d'argan pour certifier sa qualité, établir une norme officielle et obtenir une indication géographique protégée, des analyses pharmacologiques certifiant la sécurité de l'huile d'argan et enfin un fort désir de développer les zones rurales marocaines en mettant en place des coopératives de femmes et en facilitant l'accès des femmes à l'éducation.Mots clés : huile d'argan / huile alimentaire / huile cosmétique / Maroc / recherche-action
