Technological innovation is a matter of interest to governments, decision-makers, entrepreneurs, and researchers due to its impact on competitiveness, which is why publications in this field have grown exponentially. To synthesize the main research topics and highlight possible lines for future research, this work aims to develop a bibliometric analysis of technological innovation in the field of the food industry, based on the review of 1015 papers published in specialized journals. The methodology consists of analyzing bibliometric indicators of quantity and quality using the VOSviewer and SCIMat tools. The results show recognition of the different lines in which the research has organized the debate, grouping them into 12 main themes positioned on a strategic map. Furthermore, this study presents directions for future research obtained from the analysis of existing gaps. This study contributes to the literature on innovation by providing a systematization of technological innovation in the food industry.
