To cope with the pressure of modern life, consumer demand for convenience foods has increased in the last decades. The current study set out to compare the costs of buying industrially processed dishes and of preparing them at home.
Direct purchase costs of industrially processed dishes frequently consumed in France (n 19) and of the ingredients needed for their home-prepared counterparts (n 86) were collected from four major food retailers' websites in Montpellier, France. Mean prices and energy density were calculated for four portions. Costs related to energy used by cooking appliances and time spent preparing dishes were further estimated.

Not applicable.
Based on the costs of ingredients and energy used for cooking, dishes prepared at home cost less (-0·60 € per four portions, P < 0.001) than industrially processed dishes, but when the cost of time was taken into account, the industrially processed dishes were much cheaper (-5·34 € per four portions, P < 0.001) than their home-prepared counterparts. There was no difference in energy density between industrially processed and home-prepared dishes.
Our findings suggest that industrially processed dishes are more profitable to consumers when the cost of time for preparing dishes at home is valued. Given the ever greater demands of everyday life, more account should be taken of the additional cost to consumers of the time they spend preparing meals at home.
为了应对现代生活的压力,消费者对方便食品的需求在过去几十年里有所增加。本研究旨在比较购买工业化加工菜肴和在家准备这些菜肴的成本。
直接从法国蒙彼利埃的四家主要食品零售商的网站上收集了法国经常消费的工业化加工菜肴(n=19)和在家准备这些菜肴所需的食材(n=86)的直接购买成本。为四份计算了平均价格和能量密度。还进一步估算了烹饪设备使用的能源和准备菜肴所花费的时间相关成本。

不适用。
基于烹饪用食材和能源的成本,在家准备的菜肴成本更低(每份 4 份节省 0.60 欧元,P<0.001),但考虑到时间成本时,工业化加工的菜肴比在家准备的菜肴便宜得多(每份 4 份节省 5.34 欧元,P<0.001)。工业化加工和在家准备的菜肴之间的能量密度没有差异。
我们的研究结果表明,当在家准备菜肴的时间成本被考虑在内时,工业化加工的菜肴对消费者来说更有利可图。考虑到日常生活的需求越来越大,应该更多地考虑到消费者在家准备餐食所花费的时间的额外成本。
