“…Furthermore, Infante et al (2008a) were able to discriminate between different cold storage periods of peach using the e-nose. Although positive correlations between e-nose and sensorial analysis have been previously reported (Di Natale et al 2001), in the present study only the e-nose was able to distinguish between different maturity levels, while the sensory analysis was unable to establish differences for 'aroma' among them. This result likely reflects the differences in sensitivity between the e-nose and the trained panel, expressed by a homogeneity of the score observed for the descriptor 'aroma' in almost all the tested cultivars, except between M1 and M2 of 'Antares'.…”

Fruit quality has been described as a property that depends on many factors. Harvest time is one such factor, described as negatively affecting the fruit quality of peaches and nectarines when carried out at early stages of maturity. In order to assess this, fruit from peach cultivars '2B40', 'Elegant Lady' and 'Sweet September', and nectarine cultivars 'Antares' and '5A29' were harvested at three maturity levels, based on ground skin colour (M1 0 green-yellow, M2 0 pale yellow and M3 0 yellow), and evaluated at harvest and after a ripening period. Evaluations included instrumental characterization, sensorial analysis and e-nose. Flesh firmness was the parameter that best segregated the three maturity levels. Sensorial attributes and acceptability did not show differences between stages of maturity, while e-nose data clustered M1, M2 and M3 into different groups. These results suggest that the maturity level at harvest, within the range evaluated in this research, does not affect the sensory quality of the product, in spite of the aroma assessed with an e-nose revealing differences among them.

“…There have been several reports on electronic sensing in environmental control, medical diagnostics and the food industry (Keller et al 1995, Schaller et al 1998, Hai and Wang 2006. Some authors reported positive applications of EN technology for discriminating different fruits' quality and many experiments were performed including testing orange (Di Natale et al 2001a), melons (Benady et al 1995), blueberries (Simon et al 1996), pears (Oshita et al 2000, Correa et al 2001, peaches (Molto et al 1999, Brezmes et al 2000, Di-Natale et al 2001b, bananas , apples , Brezmes et al 2000, Saevels et al 2003 and nectarines (Di-Natale et al 2001b). These studies showed that EN has greater potential for nondestructive quality evaluation of mangoes, which emanate different strong aromatic compounds at different stages of maturity and ripening.…”

The king of fruits "Mango" (Mangifera indica L.) is very nutritious and rich in carotenes. India produces about 50% of the total world's mango. Many researchers have reported the maturity indices and quality parameters for determination of harvesting time and eating quality. The methods currently used for determination of quality of mango are mostly based on the biochemical analysis, which leads to destruction of the fruits. Numerous works are being carried out to explore some non-destructive methods such as Near Infrared (NIR), Nuclear Magnetic Resonance (NMR), X-ray and Computed Tomography (CT), electronic nose, machine vision and ultrasound for quality determination of fruits. This paper deals with some recent work reported on quality parameters, harvesting and post-harvest treatments in relation to quality of mango fruits and reviews on some of the potential non-destructive techniques that can be explored for quality determination of mango cultivars.

ABSTRACT:The impressive chemistry shown by porphyrins in natural systems is particularly attractive for exploitation in chemical sensors. In these devices the sensing mechanisms can mimic most of the porphyrin biological reactivity, such as reversible binding, activation of small molecules, redox activity, and photoactivated processes. The simultaneous presence of multiple binding mechanisms allows porphyrins to interact with a large variety of analytes. This feature reduces the selectivity, but prompts the development of sensor arrays, where the cross-selectivity of more sensors is used to classify and identify samples characterized by a complex composition. Since 1995 the Sensors Group of the University of Rome Tor Vergata has exploited these features to prepare sensor arrays based on different transducers and aimed at several applications. These kinds of devices have been reported as electronic noses (gaseous phase analytes) and electronic tongues (liquid phase analytes) to underline that their working mechanisms are tentatively similar to that of biological senses. We report here some of the results obtained.
