The pandemic COVID 19 has upset the economic, social, financial, and general behavioral systems. Global crisis has a large impact overall and related fallouts significantly affect existent structural paradigms in every country and region across the world. In particular, the spread of COVID-19 pandemic has led to having to rethink the way we produce and consume food. Within this global change, a rise in the number of consumers who purchase food products online in order to comply with the rules aimed at limiting the circulation of the virus should be emphasized. Consequently, probably causing a long-term positive effect on m-commerce. The purpose is to elaborate on the index of the satisfaction level of consumers of purchasing food online via food shopping channels, by using key factors that characterize the online spending behavior. The analysis was carried out by collection of data deriving from an anonymous online questionnaire administrated via social networks and emails, during the ‘hot’ months of the pandemic progression in Italy, which is March-May 2020.

We analyze both dimensions of customer satisfaction (process and outcome), by means of two systems of indicators. We reduce their complexity using synthesis obtained with the Partially ordered set. Results highlight the differences between the two dimensions of customer satisfaction. Online shopping can surely contribute to reduction of food waste thanks to elimination of frenzied shopping routines at supermarkets and can open space to new fields of study. On the other hand, defining an index of the consumer’s satisfaction can alter sales strategies of m-commerce managers and entrepreneurs.

大流行 COVID 19 扰乱了经济、社会、金融和一般行为系统。全球危机对整体产生了巨大影响，相关后果显着影响了世界上每个国家和地区的现有结构范式。特别是，COVID-19 大流行的蔓延导致我们不得不重新思考我们生产和消费食物的方式。在这一全球变化中，应强调越来越多的消费者为了遵守旨在限制病毒传播的规则而在线购买食品。因此，可能会对移动商务产生长期的积极影响。目的是通过表征网络消费行为的关键因素，阐述消费者通过食品购物渠道在线购买食品的满意度指标。

我们通过两个指标系统分析客户满意度的两个维度（过程和结果）。我们使用从偏序集获得的综合来降低它们的复杂性。结果突出了客户满意度两个维度之间的差异。由于消除了超市疯狂购物的习惯，在线购物肯定有助于减少食物浪费，并且可以为新的研究领域开辟空间。另一方面，定义消费者满意度指数可以改变移动商务经理和企业家的销售策略。
