3.2 Mineral contents mg/100 gFrom the data illustrated in Figure 1, the high mineral contents (P and K) of ice cream fortified with inulin and oat flour were observed in all treatments, but the highest P content of 21.3% was observed in T1 fortified with 2% oat flour, followed by 19.6% in T3. The high P and K contents in the previous treatments could be because of the higher contents of them in oat flour and inulin. In addition, the Mg content was 2.53 and 2.73%, and Fe was 1.62 and 1.38% in treatments T1 and T3, respectively. Also, the addition of oat flour led to increase in the Mg and Fe contents in ice cream samples (Youssef et al., 2016; Sayed and Khalil, 2017; Akalın et al., 2018). The calcium contents was nearly the same in all ice cream treatments.
