The confectionery industry is one of the fastest growing segments in the global food market.
Unfortunately, confectionery products, including marmalade and cakes, have low nutrition value and high
energetic value, which does not respond the rules of healthy diet. Jerusalem artichoke syrup and Jerusalem
artichoke powder made from Jerusalem artichoke roots also are valuable products, rich in inulin, as well as
vitamins and minerals, and can be used for fortification of marmalades and cakes. Concerning to new
products consumers today demand high-quality products that are safe for health, but food production
companies willing to produce new food products whom storage time is not less than of traditional food
products, to find out this information is necessary to determine the microbiological parameters of freshly
prepared new products and during storage. The objective of this work was to evaluate microbiological
parameters of sugar confectionery and pastry, also and the changes during storage time if one of ingredient is
partly replaced by product made of Jerusalem artichoke. The results of this research show, that sugar it
possible to replace with Jerusalem artichoke syrup up to 40% of total amount of sugar, and so increase
nutrition value of marmalades, taking into account the condition that after the clotting marmalades need to
leave to dry. The study indicates that Jerusalem artichoke powder can be used for enrichment of cakes also to
prolonging the storage time.
