Non-Destructive Quality Assesment by Sensor Technology

High-value fresh agricultural products. Particularly for export, must be carefully handled and sorted, in order to meet quality standards and customer demands. Texture, together with the appearance and   flavor, are three sets of qualities that govern the acceptability of fruit and vegetables to the consumer. The major driving force for the development of non-destructive testing methods for detecting fruit and vegetable quality is the desire to implement Total Quality Management and the need to evaluate the properties of each individual fruit and vegetable. The rapid development of fast and low-cost microprocessors, signal analysis methods and special sensors has opened new possibilities for using non- destructive testing of agricultural products. Important findings in these fields will be summarized and discussed. The presentation will discuss how fruit-and vegetable -quality parameters are linked to some available sensing technology, such as light reflection and transmission; delayed light emission: NTR: fluorescence; light spectroscopy; x-ray magnetic resonance (NMR); force/deflection; impact; vibration; acoustic: dielectric; microwave; and gas analysis. The discussion will concentrate on quantified analysis of data obtained the new technology to measure fruit and vegetable quality during the growth and postharvest stages. Technology for monitoring quality detection during growth and in storage (CA) as well as prediction of fruit shelf life will be presented. The review will cover several promising techniques for adapting non-destructive quality measurements horticultural products.
