Isolation of Natural Compounds with Organoleptic Properties Using Selected Advanced Extraction Techniques

Abstract

This review presents an overview of various advanced solid–liquid extraction techniques used for extraction of compounds with organoleptic properties from natural sources. These compounds are important additives to food, cosmetic, and pharmaceutical products. The most frequently used techniques are ultrasound assisted extraction and microwave assisted one, but there are other efficient techniques, such as pressurized liquid extraction, supercritical fluid extraction, pulsed electric field and enzyme assisted extraction. These techniques reduce or eliminate the volume of toxic solvents required for extraction, decrease the extraction time and mostly are more energy efficient. Low energy extraction conditions (pulsed electric field and enzyme assisted) can better preserve the compounds sensitive to heat, pH, and light.
