“…Aromatic products (concretes, resinoids, and absolutes) can be obtained by solid–liquid extraction, simply by adding the solvent to macerated plant material. Subsequently, the solvent is evaporated, retaining highly concentrated aroma oils or even solids . The solid–liquid extraction of some norisoprenoids from oak wood using a solvent mixture of water, ethanol, salts, and acids, imitating a model wine solution, was investigated by Sefton et al Several ionones and ionoles could be extracted from quince fruit juice using pentane‐dichlormethane solvent .…”

Flavours, fragrances, or aromas are valuable chemicals, with a broad range of industrial applications. The consumer's preference for ‘naturally’ manufactured aromas drives the development of biochemical production, which requires suitable product recovery. In this study, different industrially established recovery techniques, their advantages and limitations, and their possible application for aroma recovery from crude fermentation broth are reviewed. Among several techniques discussed, absorption, adsorption, and pervaporation appear to be particularly suitable for the recovery of aromas from highly diluted biochemical mixtures.

The processing of large quantities of water in biorefining processes can lead to immense costs for heating, evaporation, and wastewater disposal. These costs may prohibit the exploitation of alternative products, e.g., xylooligosaccharides from straw, which are regarded as too costly. A new counter-current extractions method is proposed that aims at low solvent (water) consumption, as well as high yields and extract concentrations. This process was evaluated with suspension extraction experiments with steam pretreated wheat straw and the process window analysis based on a mass balance for a washing and a leaching scenario. The latter was conducted with two other suspension extraction processes as a comparison. The equilibration time was found to be well below 10 min. While the suspension extraction with and without recycling need to be designed to achieve a high yield or a high concentration and low solvent consumption, the proposed extraction method can reach all three simultaneously. Thus, this new process is evaluated as a potential method to spare water and downstream costs and allow new processing pathways in second-generation biorefineries.
