Comprehensive Utilization of Avocado in Biorefinery: A Bibliometric and Co-Occurrence Approach 2003–2023

Abstract

In recent years, the consumption of avocado, both fresh and processed, has experienced a significant worldwide increase due to its recognized nutritional value and beneficial health effects. However, this industrial processing generates a substantial amount of underutilized byproducts, primarily the peel and seed, leading to significant environmental and economic challenges. Fortunately, these residues are rich in bioactive phytochemicals, making their recovery an excellent opportunity to enhance the sustainability and profitability of the modern avocado industry. This bibliometric analysis utilizes data from the Scopus platform to explore the comprehensive utilization of avocado waste. By employing a biorefinery approach and computational tools, the study aims to identify and extract value-added compounds with potential applications in the food, pharmaceutical, chemical, and cosmetic industries. The results highlight that the most relevant research topics are currently focused on sustainable and comprehensive biotransformation of avocado byproducts. Additionally, there is a growing emphasis on methods for extracting valuable products, characterizing their properties, and identifying potentially exploitable active compounds. Furthermore, research is increasingly exploring the environmental and economic factors associated with new research advancements, such as emerging environmental regulations, certifications, substitutes, and technological applications. One key gap identified in recent research advancements is the lack of a sustainable diagnostic framework for avocado utilization processes in a cascade system (multiple high-value consumer products and by-products such as bioplastic). This suggests a crucial area for future research efforts.
