Tomato pomace is the residue obtained after the processing of fresh tomatoes and consists of seeds, skin and a small amount of pulp. Considering the potential application of tomato pomace in the food and pharmaceutical industries, it is important to examine its macronutrient composition. The aim of this research was to determine the moisture content, ash content, content of lipids, proteins, total dietary fiber, insoluble and soluble dietary fiber, carbohydrates and total energy value of tomato pomace, skin and seeds. The analysis results showed that the moisture content in the samples of tomato pomace ranged from 6,0% to 9,7%. The highest ash content was recorded in the samples of skins (5,1%) and the lowest in the seeds samples (3,1%). The lipid content varied from 3,9% in the samples of skin to 26% in the samples of seeds, indicating a high lipid content in the seeds of tomato pomace. The protein content ranged from 14% in the samples of skin to 27% in the samples of seeds, confirming a high protein content in the seeds of tomato pomace. Dietary fiber was the most abundant component of tomato pomace with the lowest proportion (40%) in the samples of tomato pomace and the highest proportion (52%) in the samples of skin. Samples of skin were the richest in soluble (9,1%) and insoluble dietary fiber (43%). Samples of seeds did not contain digestible carbohydrates, while the carbohydrate content in the samples of tomato pomace was 23%. The highest energy value (424 kcal/100g) was recorded in the sample of seeds, which is expected due to the high lipid content in seeds. The result of this research contribute to the valorization of tomato pomace waste as a valuable source of macronutrients and dietary fiber. These findings can serve as a basis for further utilization of tomato pomace and reducing its harmful impact on the environment. Additionally, tomato pomace can become a cheap and available source of micro and macronutrients in the pharmaceutical and food industries.
