Abstract: Currently, the population is experiencing severe water stress mainly due to high water consumption by industries. Food and beverage processing consumes up to 90% of freshwater, resulting in large volumes of wastewater that is often treated with complex, costly and environmentally damaging processes. The purpose of this study is to perform the first bibliometric analysis to evaluate and discuss the evolution in the use of environmentally friendly technologies for wastewater treatment in food processing plants. A total of 606 documents published up to August 2022 were retrieved from Scopus. Data were manually standardized. VOSviewer version 1.5.18 and Bibliometrix version 4.0.0 were used to perform scientific mapping and evaluate bibliometric indicators of quantity, quality and structure. Scientific production is growing exponentially due to factors such as strict environmental policies and increased environmental awareness. The average number of authors per document is 4.056 and prolific authors in the field have not yet been defined. The contribution of the countries (led by the United States with 104 documents) was associated with their gross domestic product (GDP), level of trade and industrialization. Likewise, institutions from China (third place with 70 documents) have the highest contribution in the field. On the other hand, most of the journals where the documents were published are of high quality according to different metrics. According to the most influential articles, the frequency of keywords and their dynamics over time, the use of microalgae, microorganisms and plants for the treatment of effluents generated during food processing is the main trend. The processes also focus on the recovery or recycling of compounds of interest in wastewater such as phosphorus, nitrogen and carbon to contribute to the circular economy.
