Wet Milling - an overview | ScienceDirect Topics

Alkali wet milling. This method consists of soaking the raw material in NaOH (pH 13) at 85°C. Then, raw material is de-branded, cracked, and steeped in NaOH at 45°C, then ground to a powder, which is next mixed with NaOH, ground and sieved. Finally, the residue is collected (Eckhoff et al., 1999). The enzymatic wet milling.
