The endosperm of corn is rich in starch, protein, lipids, minerals and vitamins. The embryo of corn is particularly large, accounting for 10%-14% of the total weight, and contains a large amount of fat, so oil can be extracted from the embryo of corn. Because corn contains a lot of fat, corn is prone to rancidity during storage.
Corn can be ground into flour and rice. There are no grades of cornmeal, only thickness. Corn flour can be used to make steamed buns, silk cakes, etc. The protein in corn flour does not have the ability to form gluten elasticity and has poor air-holding properties. It needs to be mixed with flour to make various fermented snacks. The broken rice made from corn is called corn residue, which can be used to cook porridge and stew rice. The extremely tender unripe corn is called "corn shoots" and can be used to make dishes. Some new special corns have recently appeared on the market: fruit corn, waxy corn, and popcorn. Food review:
