Campaing on food loss reduction by web-app for online broadcasting at food corner

Abstract

The authors developed a web app for online broadcasting at food corner. To motivate the purchase of discount foods, the authors installed live cameras at food corners of 5 supermarkets and a department store, and delivered the still images, names, prices, and discount rates of discount foods via the web app. The title of the campaign was "Nokorifuku Campaign," and the campaign period was from October 8th to 31st, 2022. The total registration during the campaign period was 467, and the number of students were 91 (81 was students of Okayama University). By comparing with last year, food loss reduction effects were found at 3 supermarkets among 4 with available data, and the reduction effects also continued even in November, the next month of campaign. The authors also estimated confidential intervals of food loss reduction effects by the actual usage data of web-app by Monte Carlo simulation.
