ABSTRACT
Increasing disposable income of society and the individual., time-saving attitude., health safety (during COVID-19)., and innovation have increased consumer inclination from offline to online food delivery (OFD). Before COVID-19., eating out the home was the fashion and hangout., but after COVID-19., consumers feel safe while sitting at home. This study aims to explore the pre and current publications on online food delivery., find out the most studied country in OFD., find out the top-cited research publications in OFD., and find out the most dominant research terms in OFD. The present study reviews previous research published during the last 11 years (2012-March 2022) extracted from the www.dimensions.ai free web app. A drastic increase in publications since 2020 explains researchers' inclination toward the OFD. Two hundred twenty research articles were published during the pandemic out of 253 published in the last 11 years. The maximum researched country in OFD is the United States., followed by India and the United Kingdom. The most cited research publication has 255 citations. The most visible keywords in the present study were 'Zomato.,' followed by 'SEM' and 'OFD.' The present study has some limitations., like the database used in the study (dimensions) may not be as good as Scopus or WoS., which may give a better result. More study is required to understand the OFD topic and its survival. It is recommended that the catering industry take OFD as an opportunity along with the regular business generated through steady footfall of the customer/guest. It can be improved through proper logistics., software support., and merging with artificial intelligence. © 2022 IEEE.
