Current trends and prospects in quinoa research: An approach for strategic knowledge areas

Abstract

Currently, the demand for healthy consumption and the use of alternatives to dairy proteins for the development of foods with good nutritional value are growing. Quinoa has received considerable attention because it contains high levels of proteins, essential amino acids, essential fatty acids, minerals, vitamins, dietary fiber, and bioactive compounds. However, the content and bioavailability of specific compounds of interest are related to the genotype, agro-environmental conditions, and management practices under which quinoa is grown, as well as postharvest management. This article aimed to analyze research trends in three areas of knowledge: quinoa breeding for nutraceutical properties, plant–soil relationships focused on abiotic stresses, and postharvest and value-added transformation activities. To achieve this, a specific methodological design based on bibliometric and scientometric methods was used. Through analyses of keywords, titles, abstracts, and conclusions from publications in each knowledge area, the main research trends were identified, including their scope and key topics, the classification of trends according to their degree of development and relevance, and the core areas of knowledge. These trends reflect the current state of research. Finally, an analysis of the conclusions, recommendations, and future research sections of key publications revealed a strong relationship among breeding research aimed at obtaining varieties tolerant to biotic and abiotic stresses, the development of nutritional and functional compounds of interest for food safety, and the development of higher-value-added products. The findings also highlight the need for further research into the potential bioactivity of quinoa and the verification of its health benefits for humans.
