The raw corn for wet milling should contain 1516 per cent moisture and it should be physically sound. Insect and pest infested, cracked and heat damaged corns (treated at temperature around 75ᵒC during drying) are unsuitable for wet milling. The heat damaged corn affects the quality of oil extracted from its germ.

The process was conducted at a rotational speed of 400 rpm for 12 hours. Aggregated globular particles were obtained by dry milling due to the fast decrystallisation, whereas nanofiber dispersions were achieved in wet conditions. Interestingly, milling in the presence of PDMS led to the formation of nanosheets with a specific orientation.

AND SEPARATION The corn is coarsely milled in the cracking mills to separate the germ from the rest of the components (including starch, fibre and gluten). The corn flows to the germ separators to separate out the corn germ. The corn germ, which contains about 85% of the corn's oil, is removed from the slurry and washed. It is then dried and sold for further processing to recover ...
