Recovery of Biomolecules from Agroindustry by Solid-Liquid Enzyme-Assisted Extraction: a Review

This article aims to present the results of a literature review on agroindustry solid-liquid enzyme-assisted extraction (S-L EAE), to identify the most recent uses and types of enzymes in solid-liquid extraction. For this purpose, two search equations were made with the keywords enzymatic, solid-liquid, extraction, and by-products or wastes or residues in Scopus database, which lead to 230 resulted articles which were analyzed. Many agro-industrial wastes contain organic value compounds which required to be extracted by solid-liquid extraction techniques to take advantage of them. Therefore, incorporation of enzymes such as cellulase, proteases among others in solid-liquid extraction method is a green and eco-friendly improvement applied to this unit operation to reduce the use of organic chemical solvents and enhancing the biomolecules recovery such as phenols, carotenoids, oils, and so on from wastes or by-products from agro-industrial activities. Thus, agro-wastes are products that could be initially expected as losses which contain a significant number of biomolecules with nutraccutical, food, and pharmaceutical potential which can be extracted with high efficiency and specificity with the use of enzymes.

Automated summary

This article discusses the application of solid-liquid enzyme-assisted extraction technology in the utilization of agro-industrial waste, which can reduce the use of organic solvents and improve the recovery rate of biomolecules.
