|The study aimed at producing fiber fortified fruit jams and to evaluate the fortification influence on nutritional, textural and sensory characteristics. Following fruits were used for the fruit jams preparation: apricots (Prunus magnapavliciana), redcurrants (Ribes rubrum Detvan), cherries (Prunus avium Chestnut) and sour cherries (Prunus cerasus L). Produced jams were fortified with different percentages of bamboo fiber (1 %, 5 % and 10 %). Dry matter content, polyphenol content, textural and sensory properties were measured in experimentally produced fruit jams. Principal component analysis showed the influence of bamboo fiber fortification on measured parameters. Sensory properties were mainly influenced by 5 % and 10 % fiber addition. The addition of 1 % of bamboo fiber did not affect significantly sensory properties of experimentally produced fruit jams. The obtained results clearly indicated that a higher percentage of fiber fortification leads to reduce sensory characteristics. These changes, as the study showed, can certainly cause the product not acceptance from the side of consumers.
