Assessment of iron content of cooking water on bulgur by determining chemical, mineral, colour, textural and thermal characteristics.

The iron content in the water used in bulgur production did not have a negative effect on bulgur quality up to 2 ppm. The protein, ash, phenolic and mineral amounts and textural characteristics of bulgur were not affected by the concentration of iron in the water. As a result, high iron concentration in cooking water negatively affects bulgur's colour and antioxidant activity. Therefore, it is recommended to use iron-free water in bulgur production. © 2024 The Authors.
