Quinoa grain byproducts: Their valuable components and applications

Food industries produced many waste products each year, and it causes serious environmental problems that result in economic losses and social impact. However, some studies have reported that many wastes have potential and valuable bioactive compounds. These biomaterials have a high potential for food additives, cosmetic products, pharmaceutical applications, and biomass that can be beneficial in terms of ensuring global food sustainability. The quinoa industry is not the exception to waste production; however, in comparison with the studies from other pseudo-cereals, the quinoa industry needs more attention from the scientific community because the information from byproducts from quinoa is not widely studied, and many of the processes that have been proposed for recovering bioactive compounds from quinoa are not industrially scalable. Additionally, the compounds obtained from the quinoa process are generally discarded as waste or used in animal feed. However, as described in this chapter, compounds obtained from quinoa processing can be potentially valuable bioactive compounds. The main uses of quinoa byproducts are presented and discussed, and the mainstream sectors of applications for these byproducts, such as in the pharmaceutical, health, food, and cosmetic industries, are highlighted. © 2023 Nova Science Publishers, Inc.
