No matter whether it is opened or not, the flour can't be eaten after it has expired. Because the storage time exceeds the shelf life, not only the nutrients are lost, but also the flour is likely to have bred bacteria and even insects. If it is eaten again, it may have adverse effects on the human body.

Use expired flour

Wash the dishes. When cleaning the tableware stained with oil, first take a proper amount of expired flour and mix it with hot water to make paste noodle soup, then smear it on the tableware, wait for 2 minutes and then rinse the tableware with clear water.

Clean the kitchen screen window. A lot of grease often appears on the kitchen screen window. When cleaning, first add 100g flour into the basin, mix it with hot water and smear it on both sides of the screen window. After standing for ten minutes, brush it several times.

Wipe the tap. When wiping the faucet, first sprinkle a proper amount of flour on the rag, and then wipe it back and forth on the faucet after getting wet, which can remove stubborn water stains on the faucet.
