Microwave assisted extraction of pectin from waste Citrullus lanatus fruit rinds

Optimization of microwave-assisted extraction of polyphenols from Quercus bark

“…Its use is increasingly widespread in the extraction of different compounds: lipid extraction from microalgae (Dai et al, 2014), pectin from waste Citrullus lanatus (Prakash Maran et al, 2014), anthraquinones from roots of Morinda citrifolia (Hemwimon et al, 2007), essential oil from dry spices (Farhat et al, 2010), and polyphenols from Pinus radiata (Aspé and Fernández, 2011) and Pinus pinaster (Chupin et al, 2015) barks.…”

Microwave-Assisted Extraction of Polysaccharides

“…In general, pectin extraction efficiency is improved by raising microwave power. Microwave radiation loosens the cell wall of plant material and the skin tissues are opened (Kratchanova et al 2004;Prakash Maran et al 2014). Therefore, the extracting agent can easily interact with the matrix to extract the pectins.…”

“…Irradiation time should be also carefully selected, as an increase of this parameter can help the extraction but an excessive time exposure can give rise to the degradation of pectins (Prakash Maran et al 2014). These effects are shown in Fig.…”

Influence of Microwave and Ultrasound pretreatment on Solvent Extraction of Bio-components from Walnut (Julgans regia L.) Shells

“…A recent modification to conventional extraction has focused on selectively increasing the accessibility of the pores that contain the targeted active compounds [13][14][15][16]. This can be achieved either by sample pretreatment before solvent extraction or by combining auxiliary energy to the existing extraction units [17][18][19][20]. Both processes reduce analysis time, energy consumption and solvent usage, while producing higher yields relative to conventional extraction [21].…”
