Traditional cooking vs grocery store keal kits; a quantitative comparison of generated food waste using a food waste diary
Grocery store meal kits, as a relatively new method of cooking, became popular in the last couple of years. These meal kits are bought in-store, include pre-portioned ingredients together with a recipe, and differ from traditional cooking in the way how meals are planned, bought, and cooked. Food preparation showed to significantly influence food waste generation, moreover, consumers are the biggest contributor to the total amount of food waste. The objective of this study was to investigate whether and how grocery store meal kits influence food waste generation, compared to food waste generation by a traditional method of cooking. 33 Dutch households used a food waste diary to report their food waste for seven days long. Data was analysed using Multiple Regression Analysis. Results showed that cooking with a grocery store meal kit negatively impacts food waste generation. Planning routines, shopping routines, and cooking skills did not significantly impact the strength of this relationship. These results are the first academic indication that grocery store meal kits assist in reducing food waste at the consumer level. Grocery store managers may use these insights in their communication on how customers can help in minimizing food waste.
