Abstract
Background: The by-products of red chicory leaves are a valuable source of bioactive compounds that can be exploited in the development of functional foods. Objective: This work aimed to combine healthy properties of red chicory by-products with other ingredients in the formulation of a functional jam, which is easy and safe to swallow, especially for people suffering from dysphagia. Methods: The physicochemical parameters, as well as the total polyphenols content (TPC), was assessed in the obtained product. Results: The TPC (549.44 mg GAE/100 g) was higher than the values reported in other jams, and it remained stable along with the colour during six weeks of storage. Within the carbohydrates, 0.4% of the prebiotic fibre inulin has been detected, suggesting that this jam formulation is a promising delivery system of phenols and fibre. From the sensorial point of view, the functional jam obtained an overall good acceptability judgment. The bitterness of the red chicory is persistent, which helps people with dysphagia swallow more easily. Conclusion: The functional jam, based on chicory by-products, could be a good source of bioactive compounds, which are helpful even in the disabled subjects’ diet.

Summary
Cichorium intybus L. belongs to the Asteraceae family, and it is commonly named chicory. This plant is of great commercial interest, and its farming is widely distributed in Asia, North America, and Europe. Besides its economic and culinary features, chicory is noteworthy for other reasons. It belongs to traditional medicine since all parts of this plant contain potentially healthy bioactive compounds [3]. The by-products of red chicory leaves are a valuable source of bioactive compounds that can be exploited in the development of functional foods
