Abstract

Changes in quality properties of air heat-treated (45°C for 0, 2 and 4 h) strawberries were investigated. As treatment time increased, most of physical, chemical and DNA quality properties decreased significantly. After 4 h, however, fruits showed the highest L* value, Hue angle, pH, SSC and total phenolic accumulation. The results of multiplex PCR assays showed two amplified fragments for all samples extracted from achenes. In thalamus, conversely, the number of amplified fragments decreased with time, indicating great degradation of DNA in this tissue.

PlumX Metrics

PlumX Metrics provide insights into the ways people interact with individual pieces of research output (articles, conference proceedings, book chapters, and many more) in the online environment. Examples include, when research is mentioned in the news or is tweeted about. Collectively known as PlumX Metrics, these metrics are divided into five categories to help make sense of the huge amounts of data involved and to enable analysis by comparing like with like.
