“…About a decade ago, the electronic nose was introduced as a very rapid tool for aroma profile analysis in several fields, including medical diagnosis [9], environmental pollution monitoring [10,11], cosmetics [12], and the automotive industry [13]. More recently, it has become more popular as a nondestructive technique for food analysis.…”

An electronic nose was successfully used to detect and discriminate lard from other types of animal body fats and samples containing lard. The results are presented in the form of VaporPrint TM , the image of the polar plot of the odor amplitudes from the surface acoustic wave (SAW) detector frequency. In the VaporPrint TM , the radial angles representing the sensor provides individual fingerprints of the aroma of different animal body fats. Principal component analysis (PCA) was used to interpret the data and it provided a good grouping of samples, with 61% of the variation accounted for by PC 1 and 29% accounted for by PC 2. All of the lard-containing samples formed a separate group from the samples that were free from lard. This method can be developed into a rapid method for detecting the presence of lard in food samples for Halal authentication.

Electronic noses (ENs) have recently emerged as valuable candidates in various areas of food quality control and traceability, including microbial contamination diagnosis. In this paper, the EN technology for microbiological screening of food products is reviewed. Four paradigmatic and diverse case studies are presented: (a)Alicyclobacillusspp. spoilage of fruit juices, (b) early detection of microbial contamination in processed tomatoes, (c) screening of fungal and fumonisin contamination of maize grains, and (d) fungal contamination on green coffee beans. Despite many successful results, the high intrinsic variability of food samples together with persisting limits of the sensor technology still impairs ENs trustful applications at the industrial scale. Both advantages and drawbacks of sensor technology in food quality control are discussed. Finally, recent trends and future directions are illustrated.

This study was aimed at the development and evaluation of regioregular poly (3-hexyl thiophene) (rr-P3HT) based chemoresistive sensors to detect the alcoholic volatile organic compounds (VOCs): 3-methyl-1-butanol and 1-hexanol, found to be present in spoiled and Salmonella typhimurium contaminated beef packages. The sensors were developed using two types of dip coating methods: (1) vertical dip (90°), and (2) inclined dip (10°). Five layers of rr-P3HT were deposited on tin interdigitated flame retardant FR4 substrates. The morphological studies revealed that the rr-P3HT sensors developed with the inclined dip coating method had formed relatively smooth thin-film of rr-P3HT than sensors developed using the vertical dip coating method. The sensitivities of the vertical dip and inclined dip coated sensors were found to be repeatable for the same concentration and were also reproducible among different sensors for same VOC. The sensors exhibited selective response to trace level concentrations of 3-methyl-1-butanol and 1-hexanol, with a lower detection limit of about 10 and 15 ppm, respectively.
