Abstract: The tubers of Jerusalem artichoke typically comprise about 80% water, 15% carbohydrate, and 1 to 2% protein. Jerusalem artichoke tubers have a high mineral content they are especially rich in potassium (150 to 657mg100 g–1) (Kays, Nottingham, 2007). Potassium is a type of mineral called an electrolyte. Electrolytes conducts electrical impulses throughout the body. They assist in a range of essential body functions, including blood pressure, normal water balance, muscle contractions, nerve impulses, digestion, heart rhythm. The aim - to evaluate changes in the potassium quantity of Jerusalem artichoke tubers. The experiments were carried out at the laboratory of Institute of Agriculture and food sciences at Aleksandras Stulginskis University in 2015 – 2016. Jerusalem artichoke tubers of three varieties 'Sauliai', 'Albik', 'Rubik' were grown in the Petras Tinkevičius ecological farm in 2015-2016. The tubers of Jerusalem artichoke were stored in a three, controlled atmosphere chamber with different gas composition: first - CO2 – 1.0 %, O2 – 21.0 %, N – 78.0 %, second - CO2 – 10 %, O2 – 3.5 %, N – 86.5 %, three - CO2 – 15.0 %, O2 – 5.0 %, N – 80.0 %. Object of the work – Jerusalem artichoke tubers 'Sauliai', 'Albik', 'Rubik'. By applying standard methods, the change in potassium (mg 100g–1) and the dry matter (%) quantity was assessed of Jerusalem artichoke tubers. The experimental data were statistically processed by the dispersion analysis method (ANOVA), software STATISTIKA 10 (StatSoft, USA). Arithmetic means of the experimental data were calculated. Statistical reliability between data is evaluated by Fisher's LSD test.[...]
