The extraction of medicinal or functional compounds from natural materials, especially plant origin, is an important unit operation in food and bio-industries. Furthermore, the extraction of pharmaceutical compounds from plant has attracted the attention of researchers and industries due to the increasing market demands.
Generally speaking, the extraction of DF can be classified into three main types: One is a conventional solvent extraction method; second uses microwave or ultrasonic to extract DF; third is enzymeassisted extraction method. Microwave-assisted extraction and ultrasonic-assisted extraction widely used in the extraction of bioactive compounds, provides a rapid sample preparation with reduced amounts of solvent.
investigated the obtainment of SDF from white grape pomace Chardonnay, and showed that a hot aqueous extraction, 90 C, ratio substrate/ solvent of 1:4 and no gridding of the grape pomace was able to extract a great variety of polysaccharides, which were concentrated through membranes, enriching the diversity of SDF in the sample.
