Special Issue Information

Dear Colleagues,

Advanced extraction techniques have gained considerable attention in the last few decades. These techniques are emerging as alternatives to traditional methods under a new paradigm based on both the acquirement of higher yields and the development of more sustainable processes that are in accordance with green chemistry. When compared to traditional methods, advanced green procedures require shorter times, are energy efficient, and enable the efficient extraction of bioactive compounds with different polarities using reduced amounts of bio-based solvents while replacing harmful and hazardous ones. Thus, these novel methodologies for extraction have been used to mitigate the current challenges associated with the traditional extraction methods. Sustainable extraction methods include non-thermal treatment methods such as ultrasound-assisted extraction (UAE), microwave-assisted extraction (MAE), supercritical fluid extraction (SFE), high-pressure extraction (HPE), and enzyme-assisted extraction (EAE). However, although no single extraction method is capable of extracting all the desired components from food sources in an efficacious manner, these alternative techniques provide potential tools with which to develop eco-friendly processes that are safer and facilitate the production of high-quality extracts with applications in the field of functional food. Thus, this Special Issue focuses on successful cases wherein advanced techniques have been used to develop extraction procedures in food systems. Original research articles and reviews are welcome and encouraged.

Microalgae are a sustainable source for the production of biofuels and bioactive compounds. This review discusses significant research on innovative extraction techniques using dimethyl ether (DME) as a green subcritical fluid. DME, which is characterized by its low boiling point and safety as an organic solvent, exhibits remarkable properties that enable high extraction rates of various active compounds, including lipids and bioactive compounds, from high-water-content microalgae without the need for drying. In this review, the superiority of liquefied DME extraction technology for microalgae over conventional methods is discussed in detail. In addition, we elucidate the extraction mechanism of this technology and address its safety for human health and the environment. This review also covers aspects related to extraction equipment, various applications of different extraction processes, and the estimation and trend analysis of the Hansen solubility parameters. In addition, we anticipate a promising trajectory for the expansion of this technology for the extraction of various resources. Full article
