Due to their high content of phytonutrients, Allium plants are used both as food and in the treatment of many medical conditions. The increased interest in these plants is due to their powerful antioxidant properties. In this paper, the Barchart logarithmic diagram allowed us to identify the representative nutritional components for each investigated product (onion, garlic, wild garlic and leek plants), allowing us, at the same time, to identify potential mixtures of dehydrated powders to be recommended to the consumer according to his nutritional deficit. Based on the generalized model, the following potential powder mixes were highlighted and characterized by mathematical modeling in order to make food supplements: mix of garlic and wild garlic, mix of onion and wild garlic, mix of wild garlic and leek. In order to determine the moisture content, the total antioxidant capacity and the total polyphenol content of the leaves of wild garlic, onion bulbs and garlic, the following methods were used: thermogravimetric analysis, analysis of the total antioxidant capacity using the CUPRAC method, determination of the polyphenol content using the method Folin-Ciocalteu.
