Application of the biospeckle method for monitoring bull's eye rot development and quality changes of apples subjected to various storage methods-preliminary studies.

Adamiak A, Zdunek A, Kurenda A, Rutkowski K - Sensors (Basel) (2012)

Bottom Line: After that time, 34% of 'Pinova' and 21% of 'Topaz' apples displayed visible surface lesions.In the second experiment various storage conditions were used and apples were tested during their shelf life by non-destructive and destructive methods.This study showed that biospeckle activity decreased during shelf life, irrespective of storage conditions.

ABSTRACT
In this study, the biospeckle technique was evaluated for monitoring of apple bull's eye rot development and product quality in general, during storage under various conditions and during subsequent shelf life. This non-destructive optical method is based on the analysis of laser light variations scattered from the sample. Apples of the cultivars 'Pinova' and 'Topaz', susceptible to bull's eye rot, were used in two independent experiments. In the first, apples were non-destructively monitored for five months during cold storage. After that time, 34% of 'Pinova' and 21% of 'Topaz' apples displayed visible surface lesions. The increase of biospeckle activity was observed during the development of fungal disease. In the second experiment various storage conditions were used and apples were tested during their shelf life by non-destructive and destructive methods. This study showed that biospeckle activity decreased during shelf life, irrespective of storage conditions.

Mentions: The device for biospeckle measurement was similar to that previously used by Zdunek et al. [16–19]. Its schematic illustration is presented in Figure 1. In this study, two similar systems, equipped with differed laser for illuminating the sample were used.
