| Abstract | ||||
| This study aimed to evaluate produced weaning food based on wheat grains low in its content of phytic acid PA which inhibits the minerals absorption such as Ca, Fe and Zn. These minerals are of special importance in infants nutrition. A laboratory formula of weaning food was prepared named N with low content of PA by naturally activation of phytase. It was compared with 6 samples of commercial weaning foods from local markets. Phytic acid, phosphorus and its derivatives and the absorption of previous minerals were determined in all samples. The results showed that PA in commercial weaning food samples ranged from 73.798 to 352.642 mg/100g., while reduced to be 6.670mg/100g for N sample. The percentage of phytate phosphorus to total phosphorus ranged from 7.150 - 20.161 % for the commercial samples, but it was just 0.520 %, for the N sample. The phytate: Ca, Fe and Zn molar ratio ranged from 0.010 to 0.214 , 0.921 to 3.842 and 2.140 to 3.810 respectively for the commercial samples, while the N sample recorded 0,001 , 0.038 and 0.091 respectively. This study was carried out to evaluate produced novel weaning food based on wheat grains low in PA by activation of naturally occurring phytase. Also, this novel product was compared with some commercial weaning products. | ||||
