INTERNATIONAL JOURNAL OF FOOD ENGINEERING(2023)
摘要
The total quantity of food waste in Europe has been estimated at around 88 million tons per year. About 42 % is thrown out by households, of which 60 % would be avoidable by increasing users' awareness. The present paper aims to develop an integrated system to reduce household food waste and improve the end-users' lifestyle in terms of health and well-being. A smart fridge able to track the stocks, a web application and a set of related services have been designed and prototyped to guide the user in the proper storage of food and support him/her in purchase planning and food preparation. The system was positively evaluated in terms of usability, it is use contributes to both environmental and economic benefits, leading respectively to a reduction of environmental impacts of about 21 % and a yearly savings amounting up to 285 euro, in comparison with a traditional system.
