In recent years, focus on health and well-being has sparked a rising interest in bioactive compounds in food industries. These components are gaining much more popularity due to their numerous health benefits. Due to this reason, the demand for these compounds has also increased, whether it comes from edible or non-edible sources. Conventional techniques were time-consuming and were yielding low-extract products, so this problem raised the demand for modern extraction techniques. Novel techniques, including microwave-assisted extraction, ultrasonic-assisted extraction, and supercritical-assisted extraction, are better performing as compared to previous techniques. Their benefits include time saving, less solvent use, and better extract product yield, making them superior as compared to conventional techniques (maceration, percolation, and Soxhlet extraction). The drawbacks of old traditional techniques and the benefits of modern techniques make researchers and industries adopt new methods for extractions. At this point, novel techniques proved to be a sigh of relief for their users and changed the whole trend of extraction techniques. As the world is talking about environmental protection and sustainability, novel techniques also have a slight upper hand in this sector. Because some of the conventional techniques require high temperatures for the extraction process to be carried out. While on the other hand, novel techniques are non-thermal in nature, so they are more environmentally friendly and sustainable. The core aim of this review is to gain a comprehensive knowledge and understanding of principles and benefits of novel techniques in comparison to traditional techniques. A detailed overview of MAE, UAE, and SFE from different studies has been emphasized in this review, mainly focusing on the differences of different control parameters, bioactive compounds, and their benefits.
