Based on an innovative approach, the solution consists of two main products: Culinary references created collaboratively with chefs, health professionals and a community of scientists. A digital application based on artificial intelligence to help kitchen teams to create and customize meals. The solution allows the restaurant to achieve qualitative and economic objectives: • Optimize taste, • Maximize nutritional intake, • Promote healthy and sustainable food, • Reduce food waste, • Optimize the operational efficiency of kitchen teams, • Promote quality local products. Culinary references On the basis of recipes, culinary references are created in the laboratory to offer a better taste quality, an optimized response to the nutritional needs of guests and a diet that promotes health. They integrate all the data allowing to take into account the constraints and needs of the guests (food allergies and intolerances, pathologies, lifestyles, new dietary practices such as vegetarianism, physiological characteristics). They also integrate the restaurant's budget data and kitchen equipment to guarantee the feasibility of meals and the economic constraints of the restaurant. Customization of meals Based on the culinary references and according to the personal profiles of the guests, algorithms help the catering manager to create an adapted meal plan. Guest Application A mobile application and a website allow the guest to fill in his personal profile, to choose his dishes and to reserve his meals. Kitchen Application Kitchen teams have functionalities for calculating product needs, managing supplies, planning and producing meals.
