Non-destructive techniques and systems for detection of saffron quality and adulteration

Saffron as one of the most valuable medicinal plants is exposed to more fraud due to the high price. Adulteration reduces the saffron quality and leads to create the unhealthy product. It is a challenge facing international markets especially when saffron is used as a medicine. Common methods for saffron quality assessment and distinguishing the adulterated saffron include chromatographic-based methods which are time-consuming, expensive, and destructive. In this paper, non-destructive techniques and systems for rapid detection of saffron quality and adulteration was introduced. Due to their capabilities and advantages, near-infrared spectroscopy, machine vision and electronic nose are suggested as the powerful non-destructive technologies for fast and low-cost assessment of saffron quality and detection of product adulteration. Moreover, these techniques are suitable for developing the smart portable systems. It was also noted that the combined use of these systems can provide more information about the various quality aspects of the saffron
