Infants and young children have diverse dietary needs, so conducting a detailed analysis of the food they consume in terms of antioxidant activity and the content of antioxidant elements is of utmost importance. The aim of the study was to assess the antioxidant properties and the content of Cu (copper), Se (selenium), and Zn (zinc) in baby products. A total of 398 samples of ready-to-eat food consumed by children were tested. To evaluate the antioxidant activity (338 samples, without dairy), the Folin-Ciocalteu method and the 2,2-diphenyl-1-picrylhydrazyl radical scavenging test (DPPH) were employed to determine the total phenolic content (TPC). For the determination of mineral component content (398 samples), atomic absorption spectrometry (AAS) was used to analyze the levels of Cu and Zn, while inductively coupled plasma mass spectrometry (ICP-MS) was utilized for the quantification of Se. Fruit and vegetable mousses exhibited the highest average total phenolic content (TPC) and the highest percentage of free radical scavenging in the DPPH test. In terms of mineral content, the group of dairy products recorded the highest average levels of Cu and Se, while porridges contained the highest content of Zn. Notably, only organic baby food contained significantly more Zn compared to conventional food (12.2 ±: 13.9 mg/kg vs. 10.7 ±: 14.4 mg/kg). Ready-to-eat products designed for consumption by children provide antioxidant properties, and the presence of Zn, Cu, and Se can contribute to supporting antioxidant processes.
