Publication date: Available online 20 November 2019Source: Trends in Food Science & TechnologyAuthor(s): Jixian Zhang, Chaoting Wen, Haihui Zhang, Yuqing Duan, Haile MaAbstractBackgroundBecause of the important role of bioactive compounds in functional foods and health care, more and more attention has been paid to the active components extracted by green extraction methods. However, how to ensure the extraction yield and biological activity during the extraction process is an urgent problem to be solved. Subcritical water extraction (SWE) is a promising engineering method, which provides an environmentally friendly technology for extracting various bioactive compounds from natural products. Especially, under high temperature and high pressure, subcritical water can change the polarity and dielectric constant of solvents, thus contributing to a better extraction process, improving the mass transfer efficiency of the extracts and maintaining its biological activities, which has a high application prospect.Scope and approachThis review provided an update overview on the fundamental principles and bioactive compounds extraction with subcritical water. This will contribute to deepen the understanding of SWE and provide theoretical basis and reference value for further improving the application of subcritical water.Key founds and conclusionsIt is expected that this green and efficient extraction technology will be increasingly applied in the extraction of more bioactive ingredient...
