2.2. Jam making
Carrot jams were obtained by two methods (named common and mild), which differentiated for the ingredients and for pro- cessing. In both methods the content of the carrot pulp incorpo- rated was over 60%, in order to obtain a carrot “extra jam” (European Commission, 2001) with a reduced sugar content.
After processing, jams were hot-packed at 85 C (Rababah et al.,
2011) in sterilized jars and immediately sealed with a cover to reduce the inner air pressure after cooling. To preserve nutritional value, according to Wicklund et al. (2004), samples were stored at
4 C until the time of analysis, carried out as described in the following paragraphs.
