The difficult task of scaling up ultrasound use in the food sector of Latin America: A topic of research, development, and innovation

In Latin America, ultrasound research in the food industry is highly relevant to the scientific community. However, its industrial scaling faces significant challenges. This study aims to analyze ultrasound scientific research and technological development in the food sector, emphasizing Latin America compared to global trends. A comprehensive analysis of scientific research published between 2015 and 2024 was conducted using Web of Science and Scopus. Additionally, a technological mapping of patents was conducted using databases like PatentScope, Espacenet, and Lens. China and the United States are the main producers of scientific studies globally. In Latin America, Brazil leads in research studies, contributing 10 % worldwide, followed by Mexico and Colombia. In contrast, the number of patents related to ultrasound use in the food sector is 47 % lower than that of scientific publications, with the same countries leading globally and in Latin America. The results show that this region, despite the increase in scientific publications on the topic, requires public policies and funding programs that encourage patent registration in the food sector to help reduce the gap with leading countries such as China and the United States. To achieve this, it is important to strengthen collaboration among academia, industry, and government in order to translate applied research into industrial developments. In addition, this region can leverage its potential in natural, technological, and human resources to position itself as a potential leader in developing sustainable, scalable, and competitive food technologies. This could contribute to the economic and social development of Latin America. Finally, the increase in patents and technological developments will help drive sustainable innovation and reduce the socio-cultural gaps in the region.
