“…Conventionally, secondary metabolites were extracted using techniques such maceration (MAC), percolation, solvent, and Soxhlet extraction (SE). In the past few decades, green extraction techniques such as supercritical CO 2 extraction, instant controlled pressure drop (DIC), ultrasound‐assisted extraction (UAE) and microwave‐assisted extraction (MAE) have rapidly gained interest globally as these techniques are less‐laborious, fast and have increased extraction yield as compared to the conventional methods . Also these techniques are environmentally friendly as they involve reduced solvent and energy consumption …”

BACKGROUND In this study, we aimed to evaluate the influence of different extraction procedures [decoction, homogenizer‐assisted extraction (HAE), infusion, maceration, Soxhlet and ultrasound‐assisted extraction (UAE)] on the chemical profiling and biological properties of methanol and water extracts of Pulicaria dysenterica (L.) Bernh. The chemical profiles of the extracts were evaluated by high‐performance liquid chromatography coupled to electrospray ionization and time‐of‐flight mass spectrometry (HPLC‐ESI‐TOF‐MS). The antioxidant properties and enzymes (lipase, α‐amylase, α‐glucosidase, tyrosinase and cholinesterases) inhibitory potential of the extracts were evaluated. RESULTS The chemical profiles were dependent on the type of extraction methods as well as on the type of solvent. The methanolic extracts showed higher levels of total phenolic, flavonoid, and phenolic acid content, while the highest total flavonol content was observed in the HAE–water extract. Forty different compounds were identified from P. dysenterica. In relation to the potential in vitro anti‐diabetic effects, the highest activity against the studied key enzymes was observed for the macerated extract (α‐amylase: 0.58 ± 0.03 and α‐ glucosidase: 1.65 ± 0.03 mmol ACAE g−1). The HAE–methanol extract was the most potent inhibitor of cholisterases, whereas the highest activities against tyrosinase were observed for UAE–methanol extract, followed by macerated and Soxhlet. The inhibitory activity of the studied extracts against lipase were in the order: soxhlet > macerated> HAE–methanol > UAE–methanol. CONCLUSION This study has established scientific baseline data on the therapeutic properties of P. dysentrica, thereby advocating the need for further investigations in an endeavour to develop novel pharmaceuticals from this plant. © 2019 Society of Chemical Industry

“…DIC pretreatment has shown a positive and significant effect on the extraction of different phenolic compounds from grape stalk powder executed with several types of solvents. 9 Another study has proved that DIC promoted enhanced lipid extraction from rapeseed and jatropha seeds without significant modification of fatty acid composition in comparison with conventional Soxhlet extraction. 10 Allaf et al 11 in their study showed that lipid extraction could be enhanced by DIC treatment and was aptly evidenced by calculation of effective diffusivity.…”

“…These are considered at the same time as a rich source of phenolic compounds and pollutants [101]. Thus, to improve the extraction of phenolic compounds from grape stalks, Sánchez-Valdepeñas et al [99] applied DIC as a pre-treatment to extract the phenolic compounds. During the extraction of phenolics, one of the most influential factors is the size and porosity of the solid particles to ensure solid solvent contact.…”

Food processing systematically aims at meeting the needs of consumers who are looking for total high quality and perfect food safety. As the various thermal and non-thermal food preservation technologies often affect the natural properties in terms of sensation, flavor, texture, etc., instant controlled pressure drop (DIC) has been conceived as a relevant, innovative process in this field. DIC uses high saturated steam pressure and short duration to provide a new way to expand biological matrices, improve drying, decontaminate, and extract biologically active compounds, among other attributes. Therefore, this review focuses on describing the applications of DIC technology on a wide range of products such as foods and by-products that have been processed both in the laboratory and on an industrial scale. The application of DIC has shown the possibility of a significant leap in quality improvement and cost reduction in the food industry. DIC reduces the drying time of fruits and vegetables, and improves the extraction of essential oils, vegetable oils, and antioxidant components. It also provides strong decontamination, eliminates vegetative microorganisms and spores, and reduces non-nutritional and allergenic components. Over the past 33 years, this technology has continued to expand its food applications and improve its characteristics on an industrial scale. But there are still many food unit operations that can be taken to the next level with DIC.
