Produção biotecnológica de nutracêuticos utilizando resíduos agroindustriais : uma revisão

Abstract

Nutraceuticals are products of natural origin that have properties beneficial to health. They constitute a growing market driven by greater concern for health and nutrition. The nutraceutical definitions are broad and lack a legislative framework. Its production is very diversified, varying according to the raw material and compound produced. Agroindustrial residues show potential for the production of nutraceuticals, due to their content of bioactive substances, in addition to the costs involved in their disposal. Fermentative and enzymatic processes have economic and environmental advantages. This study carried out bibliographical research in databases such as the CAPES Portal, ScienceDirect, Web of Science, Scielo, INPI and Espacenet on the production of work related to the biotechnological production of nutraceuticals from waste and industrial by-products. 57 works were used, including articles and patents. The most used sources of residues and by-products were the processing of cereals and fruits. The most produced compounds were carotenoids, omega-3 acids, oligosaccharides and peptides. The most tested physiological function was antioxidant and anti-inflammatory. The most used enzymes were cellulases, xylanases and proteases. The microorganisms of greatest interest were filamentous fungi such as Aspergillus niger, lactic acid bacteria and yeasts such as Saccharomyces cerevisiae. Waste proved to be an important source of nutraceuticals and deserves attention for studies to increase industrial viability to promote a circular and sustainable economy.
