We studied the biopotential for tiger nut tubers of edible meadow (Cyperus esculentus L.) and the possibility of their use in the technology of food products with high biological value. Tiger nut tubers of edible meadow satiety grown on the Zhuravsky farm in the Korenovsky district of the Krasnodar region, harvested in 2021, were chosen as the objects of study. During the study, the organoleptic characteristics of tubers and their physicochemical properties were determined by standard methods, lipid extraction was carried out according to the Folch method, the content of vitamin E was determined by optical density on an SF-46 spectrophotometer at a wavelength of 483 nm using ethyl alcohol as a solvent. Analysing the indicators of the biological value for the object of study was carried out by the calculation method in comparison with ideal fat, vegetable oils, and hazelnut kernels. It has been established that oleic acid, linoleic acid, and palmitic acid are the main MUFAs, PUFAs and SFAs, respectively. When comparing the ratio of the content of MUFA, PUFA, and SFA in edible meadow tubers, vegetable oils, and hazelnuts, it was found that not all declared products correspond to ideal fat (1:1:1), while the ratio of PUFA:SFA is at the recommended level (0.2–0.4) only in edible meadow satu (0.28). Among the presented crops, in terms of ω6:ω3, tubers (23:1) are in second place in terms of their proximity to the ideal ratio of 10:1. The highest content of vitamin E(141 mg/100 g of product) among the presented crops is found in edible meadow grass, which is 2.1 times more than in sunfloweroil, 10.8 and 3.2 times more than olive oil and hazelnut kernels, respectively. Thus, tubers of edible meadow succulent (Cyperus esculentus L.), grown in the Krasnodar region, are a valuable crop with a high biopotential, primarily as a source ofMUFA, PUFA, vitamin E, and are recommended for use in the food industry.
