Effects of postharvest storage conditions on phytochemical and radical-scavenging activity of pomegranate fruit (cv. Wonderful)

Changes in phenolic compounds and antioxidant activity of sour–sweet pomegranates cv. ‘Hicaznar’ during long-term storage under modified atmosphere packaging

“…However, no significant difference in the ascorbic acid content was found between control and MAP-treated pomegranates after 180 days of cold storage and 180 + 3 days SL at 20 C (Tables 1 and 2). Our findings are in agreement with those of Arendse et al (2014), Barman et al (2014) and Abd-elghany et al (2012) who reported a gradual decrease in ascorbic acid content in pomegranates during storage. The reduction in the level of ascorbic acid might be the result of delayed biosynthesis or fast degradation of ascorbic acid in MAP-stored fruit (Khan and Singh, 2008).…”

The comparison of the physicochemical parameters and antioxidant activity of homemade and commercial pomegranate juices

“…Ascorbic acid was found in tested juices at the levels of 15.7-26.8 mg% (HM) and 9.1-16.1 mg% (CA). This is in agreement with Ranu and Uma (2012) as well as Arendse et al (2014) who found AA levels of 19.8 mg% and 16.82 mg% respectively in fresh pomegranate juices.…”

“…Radical scavenging activity (RSA) was investigated using the 2.2-diphenyl-picrylhydrazyl radical (DPPH) according to the procedure performed by Arendse et al (2014). 10-fold diluted aqueous solutions of pomegranate juices were used.…”

Effect of active-modified atmosphere packaging on the respiration rate and quality of pomegranate arils (cv. Wonderful)

“…Anthocyanins are water soluble polyphenolic compounds responsible for the red colouration in pomegranate fruit peel and arils (Alighourchi et al, 2008;Arendse et al, 2014). Total anthocyanin concentration fluctuated with storage in MAP-A (5 kPa O 2 + 10 kPa CO 2 + 85 kPa N 2 ), MAP-B (30 kPa O 2 + 40 kPa CO 2 + 85 kPa N 2 ) and clamshell packages, throughout the storage (Table 1).…”
