Fortification of cereal groats with iron and zinc using ultrasound
The research is devoted to fortification of cereal groats with iron and zinc using ultrasound. Three factors were studied: ultrasound frequency at levels 35 kHz and 42 kHz; processing time at levels 10, 15, 20, 25 and 30 minutes, and temperature at levels 25, 30, 35, 40, 45, 50, 55 and 60ºC. All fac...

Summary: | The research is devoted to fortification of cereal groats with iron and zinc using ultrasound. Three factors were studied: ultrasound frequency at levels 35 kHz and 42 kHz; processing time at levels 10, 15, 20, 25 and 30 minutes, and temperature at levels 25, 30, 35, 40, 45, 50, 55 and 60ºC. All factors had statistically significant effects on the absorption of iron and zinc ions both for pearl barley and oat groats, and no interaction effects between factors were found. Four multiple regression models with the coefficients of determination in the range of 0.951 to 0.985 were developed to predict the ions Fe2+ and Zn2+ absorption by cereal groats. |
