Influence of the storage duration on the health promoting tyrosine, tryptophan, and total phenolics in potato tubers

This research investigated the influence of the storage duration on the health promoting tyrosine, tryptophan and total phenolics in potato tubers. In the course of storage, the total amount of accumulated compounds in the dry mass of organically grown potato tubers increases. This is determined by individual properties of potato variety, storage time, and interaction of these two factors (P < 0.05). Organic potato tubers show increased total phenolic compounds in their dry matter during storage. This is due to a variety of characteristics, storage time and the interaction of these two factors (P < 0.05). A more pronounced increase in total phenolic compounds during storage was observed in 2022 than in 2021.
