The demand for nixtamalized products has broadened the industrialization of maize. The nejayote is a product of the alkaline cooking of grain, and unfortunately contributes to environmental deterioration after being dumped into the public sewer system. There is evidence that adequate treatment of this byproduct not only reduces pollution, but it is also a source of compounds with high added value with potential for technological applications. The objective of this review was to provide an overview of the main methodologies and technological developments which have been implemented to explore the physicochemical properties of nejayote and to assign a treatment or an application to it. With the work performed it was possible to detect that the recovery of materials with high added value (polyphenols, carbohydrates, sugars, gums and calcium components) can be used in various areas such as the food, pharmaceutical and biotechnological sectors. In addition, it was identified that the obtaining of these components can be carried out through the coupling of various bioprocesses (fermentation, filtration, centrifugation and decantation).
