Connection Between the Debranning Time and the Kernel Hardness of Wheat

Abstract

Surface cleaning has an important role in the technology of milling of wheat considering food security. Wheat hardness has an effect on the milling process, it determines the properties, qualities and end use of flours. In the last decade new debranning methods have appeared, which are able to better remove the shell of wheat grains applying rubbing surfaces. In my thesis I examined how different levels of debranning affect hardness and content of ash in wheat types with different grain structure. Conclusion is with approximately 4% of shell removed the hardness of grain. Further removing of shell does not result in further changes though. Reduction of hard wheat's general grain size with longer debranning process is larger compared to soft wheat's.

Effect of short term storage on wheat quality parameters

“…Very important parameter of wheat kernel is the hardness of the kernel. It determines the consumption and the parameters of the technology especially that the hardness of the kernel changes as a result of debranning [5]. In Hungary wheat is usually not processed after harvesting, but it is stored for short term.…”
