This study demonstrated that HS can be utilized as an alternative source of antioxidants and dietary fibre to fortify yogurt.
The addition of HS and the percentage added contributes to the
dietary fibre content and antioxidant capacity of the final product, as well as to all of the other physico-chemical parameters
considered. During storage, the antioxidant capacity of fortified
products was increased with respect to the control, and no
modification of the phenolic compounds was observed. Thus, it is
possible to conclude that the functional ability of these products
is stable or increased during storage. The yogurt with the 3% San
Giovanni and TGT HS achieved the highest score from the consumers. By consuming 100 g of products fortified with 3% of
these two varieties, consumers obtain the 37% dietary fibre
intake recommended by the European Union and the respective
0.4 and 0.6%, polyphenol intake reported by the scientific
literature
