【 摘 要 】

Cereal bars are eaten regularly due to their nutritive values and ease of consumption. Furthermore, new cereal bars were recently introduced to serve the growing market of functional food. In this work, we aimed at developing an innovative sugar-free cereal bar with high protein and fibre content, showing functional effects and with improved sensory properties over cognate commercial bars. We developed an innovative recipe by substituting honey with a xanthan gum/erythritol mixture as binder, and by manufacturing bars in a conventional industrial apparatus. The new formula was characterised by high content of proteins (27.7%) and fibres (8.7%), whereas carbohydrates resulted drastically reduced (26.7%). Panel test analysis showed that bars hold satisfactory sensory properties (aroma, flavour and taste), whereas some texture parameters were positively changed, as hardness and adhesiveness were significantly reduced. In vitro challenge experiments showed that the phenolic components isolated from the bar matrix significantly increased the levels of glutathione and glutathione reductase in Caco-2 cells, a model of enterocytes (P<0.05). In conclusion, we produced a sugar-free cereal bar on an industrial scale with antioxidant properties, and with improved nutritional and texture parameters in comparison with a conventional product.
