The effect of various concentrations of potassium bromate (a malting additive) was studied on malting sorghum. Potassium bromate at concentrations of 50-125 mg/litre sprinkled on germinating sorghum (28 degrees +/- 1 degrees C) at steep out increased the filtration rate and cold and hot extract values after four days of germination. There was no significant decrease in malting loss at the low concentrations (50-125 mg/litre) of the additive. A higher dose, of 150 mg/litre, decreased the malting loss, while at a concentration of 125 mg/litre a significant increase was observed for the diastatic power after four days of germination.
