This extraction process involves a two-step dual-temperature approach [75]. A process for generating potassium ammonium sulfate from seawater has been proposed, involving the reaction of magnesium sulfate (obtained from chilled bitterns precipitation), aqueous ammonia, and potassium tartrate.
Extraction of phenolic compounds: A review
Extraction by maceration is a simple process of soaking a pulverized sample in the appropriate solvent in a closed system, followed by constant or sporadic agitation at room temperature (Olejar et al., 2015; Sticher, 2008). After the extraction period, a separation process is applied to separate the solid parts from the solvent.
Enzymes: principles and biotechnological applications
Many of the microbial enzymes used in biotechnological processes are secreted extracellularly, which greatly simplifies their extraction and purification. Microbial intracellular enzymes are also often easier to obtain than the equivalent animal or plant enzymes, as they generally require fewer extraction and purification steps.
