Effect of high voltage electrical discharges, heating and ethanol concentration on the extraction of total polyphenols and lignans from flaxseed cake

Sinapinic and protocatechuic acids found in rapeseed: isolation, characterisation and potential benefits for human health as functional food ingredients

“…Crucially, it was found that the extracts from rapeseed cake had a significant increase in their antioxidant activity following HVED treatments. Other studies have shown the efficacy of this technique to extract phenolics from different oilseed sources, including sesame cake and flaxseed cake (Boussetta et al, 2013;Sarkis et al, 2015). The study by Barba et al was an initial optimisation, in addition to being the first step in the search for more efficient methods to isolate phenolic compounds from rapeseed by-products.…”

An overview of the impact of electrotechnologies for the recovery of oil and high-value compounds from vegetable oil industry: Energy and economic cost implications

“…The application of high voltage electrical discharges (HVED) is based on the physico-chemical process of dielectric breakdown or arcing that occurs when the electrical discharges keep attached to water (Barba, Boussetta, & Vorobiev, 2015;Boussetta et al, 2013). This process is the result of liquid ionization after applying a pulse of high voltage (40 kV) and high current (approximately 10 kA) of short duration (μs-ms) between two electrodes.…”

“…olive, corn, soybean, canola, or sesame) (Guderjan, Elez-Martínez, & Knorr, 2007;Guderjan, Töpfl, Angersbach, & Knorr, 2005;Puértolas & Martínez de Marañón, 2015;Sarkis, Boussetta, Blouet, et al, 2015). In addition, PEF and HVED are also a tool with great potential to improve the recovery of valuable compounds, such as polyphenols and lignans from the generated waste, not only during oil production (Boussetta et al, 2013Roselló-Soto et al, 2014;Sarkis, Boussetta, Blouet, et al, 2015;Teh, Niven, Bekhit, Carne, & Birch, 2015), but also from the agricultural practices such as pruning (Yu, Bals, Grimi, & Vorobiev, 2015;Yu, Gouyo, Grimi, Bals, & Vorobiev, 2015).…”

“…polyphenols, proteins, isothiocyanates or lignans), from wastes and by-products generated during vegetable oil production process, has also received high attention (Boussetta et al, 2013Roselló-Soto et al, 2014;Sarkis, Boussetta, Blouet, et al, 2015;Teh et al, 2015). Some examples of the main findings found for the recovery of nutritionally valuable compounds from wastes and by-products generated during vegetable oil production process by using PEF and HVED are described below and summarized in Table 1.…”

Effect of pulsed electric fields and high voltage electrical discharges on polyphenol and protein extraction from sesame cake

“…Only a small number of works have been performed using oilseeds (Boussetta, Turk, et al, 2013;Grémy-Gros, Lanoisellé, & Vorobiev, 2008;Gros et al, 2003) and, to the best of our knowledge, no work has been performed using these technologies on sesame seed or cake. The goal of this study was to evaluate the effects of different variables in order to enhance extraction of polyphenols, lignans and proteins from sesame cake through the application of PEF and HVED.…”
