Impacts of low and super-atmospheric oxygen concentrations on quality attributes, phytonutrient content and volatile compounds of minimally processed pomegranate arils (cv. Wonderful)

Minimal processing of pomegranates (Punica granatumL.)—A review on processing, quality, and shelf life

“…The higher microbial counts in this study may attribute due to the presence of perforations on MAP which provide means of entrance for microorganisms during storage. The previous researchers reported that the MP pomegranate arils packed under MAP in super atmospheric O 2 (Ayhan & Esturk, ; Banda et al, ; Belay et al, ) and 100 kPa N 2 atmosphere significantly showed lower aerobic mesophilic bacteria counts throughout the storage duration. In addition to MAP, Aloe vera gel (Martinez‐Romero et al, ), chitosan coating (Ghasemnezhad et al, ; Ozdemir & Gokmen, ), and UV‐C + Hot Water + High oxygen packaging (Maghoumi et al, ) also showed potential to reduce microbial spoilage of MP pomegranate arils.…”

“…The storage temperature, time, and their interaction showed a nonsignificant effect on aril firmness during the storage period of 14 days (Caleb, Opara, et al, ). Packaging conditions (passive and active MAP) also showed a nonsignificant effect on aril firmness (Ayhan & Esturk, ; Belay, Caleb, & Opara, ). These authors also reported the highest firmness of arils stored under super atmospheric conditions.…”

“…Bhatia et al () observed the significant effect of packaging material and storage days on color ( a * and b *) value of MP pomegranate arils but their interaction (packaging material and storage days) had a nonsignificant effect on color values. In few studies, authors also reported that packaging with storage duration had a significant influence on the color intensity (Belay et al, ; Hussein et al, ; O'Grady et al, ). Hussein et al () reported a general decrease in individual color parameters of “Arakta”, “Bahgwa”, and “Ruby” MP pomegranate arils by Day 7 of storage at 1°C, 4°C, and 8°C.…”

“…Martinez‐Romero et al, reported that MP arils treated with Aloe vera gel in combination with 1% acid showed a significant increase in total phenolics after 8 days of storage whereas SA‐treated ails showed an increase in total phenols up to 13th day followed by a declining trend till the end of 19 days of storage period (Bhatia & Asrey, ). Packaging conditions, duration, and their interaction had a significant effect on the total phenolic content of pomegranate arils (Belay et al, ). Maghoumi et al () observed a positive effect of UV‐C and high oxygen on the phenolic content of MP pomegranate arils.…”

Effect of high O2atmosphere packaging on postharvest quality of purple passion fruit (Passiflora edulisSims)

“…Recent research has shown that high O 2 atmosphere could inhibit microbial growth and enzymatic browning (Jacxsens, Devlieghere, Steen, & Debevere, ). Super O 2 modified atmosphere storage maintained lower microbial counts and higher amount of volatile compounds of pomegranates arils than that of low O 2 and air modified atmosphere storage (Belay, Caleb, & Opara, ).…”
