Analytical and bioluminescence-based non-invasive quality assessment of differentially grown strawberry (Fragaria x ananassa Duch. ‘Asia’) during household refrigeration storage

Strawberry is a typical spring fruit, for which consumer demand is particularly high; however, information is scarce on the comparison of quality traits of strawberries of local and imported origin during household refrigeration storage. That is why we sought to answer the question of to what extent the quality of strawberries changes during 5 days of household refrigeration storage. The choice of methods was focused on fast and at the same time informative analytical methods: pH, total antioxidant capacity, and lipid oxidation. Furthermore, a non-invasive imaging technique: ultra-weak bioluminescence measurement was carried out along with the determination of fruit morphological (weight, height, width, and color) and analytical (antioxidant capacity and lipid oxidation) traits. The data indicate that the longer strawberries are cultivated in the same plantation, the smaller their fruit weight and the lower their fruit quality become.
