Table 2: Identification of volatile aroma compounds and their content in cloudy beetroot juice powders obtained without additional carriers (nd—no data). A significant effect of the drying temperature on the total content of aromatic compounds in the tested powders without carriers was noted. A higher drying temperature (130 \({}^{\circ}\)C) led to the formation of a high amount of volatile compounds. However, more volatile compounds in the powder from the pure juice (J130) were found than in the juice with the addition of pomace (MJ130). Presumably, a high amount of low-molecular compounds, such as simple sugars, in the case of pure juice powder resulted in more reactions and consequently the formation of more volatile compounds.
