Ultrasonic process intensification for the efficient extraction of nutritionally active ingredients of polysaccharides from bioresources #42

Abstract

To reduce the consumption of petroleum and common energy sources, it is important to look for alternative green techniques that are able to produce the same products and fulfill the same industrial applications. Power ultrasound is successful in inducing various physical and chemical transformations due to the intense pressure waves of the ultrasound in a liquid medium. Ultrasound energy could be considered as one of the new forms of energy which is promising for the applications of extraction involving the bioresources. This chapter presents the aspects of ultrasonic process intensification of the extraction of one of the most biologically active ingredients, namely, polysaccharides from diverse herbal materials. Number of studies has been surveyed and summarized to present their best outcomes in the applications of ultrasound in the extraction process. Evidently, ultrasonic conditions provide better environment for isolating the bioactive compounds and more importantly with higher preservation of the bioactivity of extracted components.
