This paper explores the relationships of various cognitive, attitudinal, and behavioural responses of e-discount sales promotion technique preferences consumers have when making purchases through online food delivery services (OFDS). This paper highlights new findings towards expanding e-discount and sales promotion literature and thus provide relevant implications.

This study aims to integrate the protection motivation theory (PMT) model and attitude to explore the factors influencing consumers’ usage behavior toward online food delivery platform services (OFDPSs) during the COVID-19 pandemic. The utilitarian value and hedonic value of OFDPSs, which may influence consumers’ attitude, were also included in the integrated research model. This study collected a total of 384 participants who are with experience in using OFDPSs during the COVID-19 pandemic in Taiwan for analysis

With the development of information technology, online food delivery services have significantly changed people’s food consumption patterns. The outbreak of COVID-19 has further facilitated the development due to restaurant restrictions and social distancing measures. Due to the emergence of online food delivery services, scholars have paid increasing attention to this popular topic, and a large number of studies have examined which factors are related to consumers’ intention to use online food delivery services. However, previous studies showed inconsistent findings, and relationships between variables lack a comprehensive understanding. Therefore, this study aimed to develop a research model and examine the factors influencing consumers’ intention to use online food delivery services. By reviewing and analyzing 52 studies with 53 independent samples (N = 22,937), the meta-analytic structural equation modeling approach was carried out to assess the research model. The findings indicate that two attributes of online food delivery services (i.e., convenience and price-saving orientation) play different roles in the research model. Specifically, convenience significantly impacted perceived ease of use but had no direct impact on perceived usefulness. Price-saving orientation significantly influenced both perceived ease of use and perceived usefulness. Moreover, relationships between perceived ease of use, perceived usefulness, and perceived trust were significant, and these factors ultimately significantly led to the intention to use food delivery services. The findings contribute to theoretical advancement in the extant literature on food delivery services and help firms develop to provide better food delivery services for consumers’ continuous usage.

The surge in food delivery systems during the coronavirus 2019 pandemic necessitated this study of heavy metal migration from food contact materials (FCMs). A total of 104 samples of FCMs, comprising 51 polypropylene (PP), 21 polyethylene (PE), and 32 polystyrene (PS) samples of six different types of FCMs (containers, covers, table utensils, cups, pouches, and wrappers) used for food delivery distributed in Korea, were collected and investigated for migration of three heavy metals (Pb, Cd, and As) using inductively coupled plasma–mass spectrometry (ICP-MS) to determine whether they complied with Korea’s Standards and Specifications for Utensils, Containers, and Packages. Acetic acid (4%, v/v) was used as the food simulant, and tests were performed at 100oC (in harsh conditions) for 30 min. Linearity of Pb, Cd, and As showed acceptable results with a coefficient of determination (R2) value of 0.9999. Limit of detection (LOD) and limit of quantification (LOQ) of Pb, Cd, and As were 0.001, 0.001, and 0.001 μg/L and 0.002, 0.003, and 0.003 μg/L, respectively. Accuracy and precision results complied with the criteria presented in the European Commission Joint Research Centre guidelines. The average concentration of Pb, Cd, and As migration detected in a total of 104 samples was 0.009–0.260 μg/L, which was very low compared with the migration specification set in the Standards and Specifications for Utensils, Containers, and Packages. The maximum level of Pb corresponded to 0.23% of the migration limit. There were no samples exceeding the limit. Thus, this study confirmed that the heavy metal contents of FCMs used for delivery food distributed in Korea were safely managed. The data from this study represent an invaluable source for science-based safety management of hazardous heavy metals migrating from FCMs used in the food delivery industry.

Since delivery food has become a new dietary culture, this study examines consumer awareness through big data analysis. We present the direction of delivery food for healthy eating culture and identify the current state of consumer awareness. Resources for big data analysis were mainly articles written by consumers on various websites; the collection period was divided into before and after COVID-19. Results of the big data analysis revealed that before COVID-19, delivery food was recognized as a limited product as a meal concept, but after COVID-19, it was recognized as a new shopping list and a new product for home parties. This study concludes by suggesting a new direction for healthy eating culture.

Various non-face-to-face services are being activated due to the influence of the Corona 19 virus around the world. However, unlike the rapid development of delivery services, social awareness of delivery services is causing many problems. Therefore, in this study, we analyze the quality attributes of delivery services from the consumer's point of view, and based on the results, we try to derive a direction for service improvement. In this study, quality factors were established through interviews and surveys with actual consumers, and quality attributes were classified through the Kano model and Timko’s customer satisfaction coefficient. “Attractive” is (‘Ease of ordering, Accurate delivery to the designated place’), “One Dimensional” is (‘Variety of payment methods, Accurate delivery on time, Accurate delivery of ordered food, Degree of non-deformation of packaging conditions, etc., Convenience of use time’), “Must be” is (‘Kindness of the delivery person’), “Reverse” is (‘provision of services, service response to order discrepancies’). This study has academic significance in that it compensated for the disadvantage of not being able to interpret the mathematical meaning of the Kano model with Teamco’s customer satisfaction coefficient. It also has practical implications in that it provides an indirect clue to future improvement directions.

This study was conducted to understand the type of use and satisfaction of delivery food by Chinese and Korean students. In December 2019, Korean and Chinese students living in Gyeonggi Province were analyzed using SPSS. The average number of food deliveries was 1~2 times a month and used 30.7% of the Korean students and 21.8% of the Chinese students. As for how to order food for delivery, 62.2% of Korean college students took up mobile apps, and 49.0% of Chinese students took up mobile phones. In terms of satisfaction after using delivery food, Korean students scored 3.89 points for taste and 3.74 points for using a neat and convenient packaging container, while Chinese students showed the highest score of 3.69 points for past eating experiences and 3.65 points for taste. As for the factors influencing the satisfaction after using the delivered food, the food quality satisfaction (β=0.518) for Korean students and favorable menu factor (β=0.533) for Chinese students were found. Therefore, it is judged that it is necessary to continuously improve the quality, service, convenience and diversity of delivered food, and health and safety factors in order to improve the delivery patterns and satisfaction of college students.

This study was performed to provide fundamental data on the convenience foods purchase according to the food-related lifestyle. This study was conducted on 398 Chinese international students residing in Gyeonggi area between October and December 2019. Among the total 373 survey subjects, gender was 183 male students (49.1%) and 190 female students (50.9%). This study was conducted by questionnaire method with reference to previous studies. There are significant differences in economic pursuit and taste pursuit for delivery food use, economic pursuit and taste pursuit for delivery food information, health pursuit and taste pursuit in delivery food ordering method, and economic pursuit and convenience pursuit for delivery food use (p<0.05). Delivery food usage time was significantly different in convenience pursuit, health pursuit, eating out pursuit, and taste pursuit (p<0.05), and the delivery food preference menu was significantly different in economic pursuit, health pursuit, eating out pursuit, and taste pursuit (p<0.05). The menu positive factors among satisfaction factors showed statistically significant differences in economic pursuit (β=0.188, t=3.531) and health pursuit (β=0.160, t=3.099) among food related lifestyle factors. In conclusion, this study presented the desirable direction of delivery food usage in Chinese students.

In this study, a survey was conducted among university students (119 men and 134 women) in Chungbuk province using questionnaires to investigate the variables and eating patterns related to the use of food delivery apps. A survey was conducted from March 22, 2019 to April 3, 2019. Of the total respondents, 77.2% reported that they had ordered food at least once using food delivery apps on smartphones. Further, 63.3% of the total subjects had ordered food delivery through smartphone apps once or twice a month, and the most preferred cuisine for food delivery was fast food, followed by Bunsik (Korean street food/snack), western food, and Chinese food. The average satisfaction scorefor food delivery apps was 3.8 points, and the satisfaction score was the highest with the convenient ordering process (4.0), followed by good taste (3.9) and good portion (3.8). The subjects who used smartphone food delivery apps three times or more a month showed a significantly higher frequency of instant food intake (p=0.0132), dining out (p=0.0282), and late-night eating (p=0.0047) than the subjects who ordered food using delivery apps less than three times a month. In conclusion, these study results may be applied as baseline data for dietary education among university students.

Food environment has been going through significant changes with the introduction of Information and Communication Technology (ICT). This study was conducted to investigate the current development status of ICT related to food delivery service by analyzing the relevant registered patents according to consumer buying process. Patents registered between 2002 and 2016 were searched with ‘food’ and ‘delivery’ as main keywords through Korea Intellectual Property Rights Information Service (www.kipris.or.kr). The search resulted in 624 patents among which 219 patents were related to food delivery service; 108 patents based on ICT were selected and analyzed. The patents were examined by applicant and year. The patents were classified into the six steps of consumer buying process: ‘need recognition’, ‘information search’, ‘evaluation’, ‘choice’, ‘purchase’, and ‘postpurchase evaluation’. Patents belonging to more than one step were coded to all the corresponding steps. The patents were registered mainly by domestic companies (50.9%) and individuals (35.2%), having shown dramatic increase of registration since 2012. Over 2/3 (67.6%) of the patents were related to the ‘purchase’ step. About 32% were associated with the 'information search' step. Approximately 18% of the patents were relevant to the 'evaluation' and 'choice’ steps, respectively. The numbers of patents related to the 'postpurchase evaluation (13.9%)’ and 'need recognition (12.0%)' steps were relatively low. The current ICTs related to food delivery service in Korea were largely associated with service providers' profit generation rather than consumers' benefit. There is still much room for technology development that could contribute to increasing consumers' benefit.
