Optimization of process variables of probe ultrasonic‐assisted extraction of phenolic compounds from the peel of Punica granatum Var. Bhagwa and it's chemical and bioactivity characterization

Intensification of bio-actives extraction from pomegranate peel using pulsed ultrasound: Effect of factors, correlation, optimization and antioxidant bioactivities

“…As it happens, a longer time of extraction may improve the more tissue disruption so as more solvent can diffuse in cells and leach out the bio-actives [16] . A similar trend was observed by Foujdar et al; Pan et al; Tabaraki et al [3] , [4] , [14] . In the case of TFC significant rise between 1 and 3 min was achieved later on; a substantial increase from 10 to 16 min was noted; nonetheless, in between, there was no significant increment in TFC.…”

“…The responses found at 210 W were 181.20 mg GAE/g of TPC, 62.03 mg QE/g of TFC, and 174.87 mg GAE/g of AOX capacity. This trend was observed by several other researchers viz., Foujdar et al; Pan et al; Sharayei et al [3] , [4] , [11] . The improvement in extraction of all the three responses might be due to the cavitation, which might have resulted in more tissue damage and elevation of mass transfer resulting in higher extraction of TPC, TFC, and AOX [30] .…”

“…The industrial processing of pomegranate fruits results in huge amounts of by-products, such as peels and seeds [2] . Though pomegranate peels (PP) are by-products, it constitutes around 78 to 80% of the pomegranate marc (on wet basis), which is also a comparably good source of high-value antioxidants than seeds [1] , [3] , [4] . PP and its natural extracts contain several primary and secondary metabolites as proteins, fats and oils, dietary fibers, sugars along with functional and nutraceutical ingredients.…”

Novel Antioxidant Packaging Films Based on Poly(ε-Caprolactone) and Almond Skin Extract: Development and Effect on the Oxidative Stability of Fried Almonds

“…A similar thermal stability than that of ASE was reported for curcumin with three degradation steps between 224–239 °C, 439–444 °C and around 570 °C [ 59 ]. Recently, Foujdar, Bera and Chopra [ 60 ] reported that plant compounds are thermally degraded in three main regions, according to the results obtained for Punica granatum peel ethanolic extracts obtained by ultrasonic-assisted extraction. The first region (up to 200 °C) was attributed to moisture loss and evaporation of volatile matters.…”

Nanotechnologies: An Innovative Tool to Release Natural Extracts with Antimicrobial Properties

“…LC analysis of the extract recorded the punicalagin (163.52 mg/g of waste) as a major ellagitannin compound. Peel extract exerted high antibacterial activity against both Gram-positive and Gram-negative bacteria [ 72 ].…”
