Abstract
The aim of this paper is to analyse through a systematic literature review the main topics studied on a relatively new concept: e-grocery. This study examines the existing literature through the use of some interactive Scopus applications with the goal to provide: (1) a better understanding of the main topics that have been analysed up to now; (2) the principal methodologies that have been used; and (3) the challenges that still exist as well as literature gaps. First, we provide a summary of what has been previously researched in the field, analysing the trends regarding time, sources, authors, countries and document types. Then, tokenization, and a natural language process (NLP) that applies the Latent Dirichlet Allocation (LDA) method, is used to extract the main topics in the field. We obtain that the research topics in the discipline have always been linked with technological changes, innovation and diffusion, and environmental effects have been a cornerstone since the origin of the field. In comparison with other fields in transport economics, we notice that experimental design and choice modelling are not very popular. As a step towards future research, we propose an integrative framework for e-grocery consumer behaviour that starts from the Engel–Kollat–Blackwell (EKB) model.

Humans need to eat in order to survive, so eating is an essential activity that is carried out several times per day [1]
This article provided a critical overview of how e-groceries/retails research has evolved in the last 20 years

Summary
Humans need to eat in order to survive, so eating is an essential activity that is carried out several times per day [1]. It is not strange that research on e-grocery has recently received more attention in many disciplines [2,3]. E-grocery is gaining momentum because it promises relative convenience to the customer, given that customers can obtain the groceries they need from the comfort of their homes or offices and at a convenient time. Despite the growing interest in e-grocery research, there is a need for an analysis that shows how the research has evolved in the past. The aim of this paper is to present a bibliometric analysis of e-grocery/e-retailing that examines the main topics and methods and offers a future research agenda
